There are more options than ever to cool off your home in the summertime. But, they’re not all equal in terms of how well they work or how much they cost. But, the right solution will deliver great hvac while costing less to run than others.

The owners of a colonial home in Andover MA were ready to make such an upgrade. For years, they used window air conditioners to cool parts of their home. But, those units were getting old. They were loud and cost a lot to run. And our homeowners were tired of having to drag them out of storage, clean them and then install them every spring.

So, they contacted N.E.T.R. to find a better way to keep their home cool in the summer. They were looking

Problem: A colonial home in Andover did not have central air conditioning. The homeowners used window air conditioners. They wanted to cool in their three bedrooms.

Solution: Installed a Mitsubishi outdoor condenser and three ductless units with one unit in each bedroom.

Adding air conditioning to a home

For decades, central air conditioning was the best way to cool an entire house. But, central ac wasn’t around in homes until the 1970s. So, all the houses built during the suburbs boom of the 50s and 60s didn’t have them.

People who lived in these houses often used fans or window air conditioners to stay cool. However, none of these are as efficient as central air.

Fans cost much less but aren’t as strong. Window units cool off a room more than a fan. But, they’re costly to run. And, they’re also very noisy and require a lot of care to keep them working correctly.

For decades, central air was the best option. But, if you didn’t have it already in your house, it’s expensive to install. Retrofitting a home takes two to three days and costs up to $4,000.

But, that’s if the house already has ductwork. If it doesn’t, you can expect to double that time —- and that cost. And, this house did not have ductwork.

Our homeowners had forced hot water heat. Their heat came through small pipes and radiators. There were no ducts in the house. To install central air, we’d have to design, build and install ducts.

That would be more than only expensive. It would also take up a lot of room in the house. We’d have to run big, bulky ductwork along ceilings and floors, and probably in closets. They would take up a lot of room, especially after we build out walls around them, so they’re not exposed.

Fortunately, we had a way to avoid all that. Our solution would work better and cost less than central air every month.

The option we offered was a ductless HVAC system. It provides just as much strength as a central unit. But, it would cost less to run. And, it would be easy, and far cheaper, to install.

How a ductless HVAC system delivers cool air

Like central air, a ductless HVAC system uses an outdoor condenser that circulates air throughout the house. But, that’s about where the similarities end.

With ductless, the air travels through small, flexible tubes instead of ducts. This design makes it much easier to install. We don’t have to do any major building or designing to put in the system. Instead, we just run the tubing through the walls.

Inside the home, that tubing connects to the units that are mounted high up on the wall. Since the tubing can run anywhere, we can place the units anywhere. This way, we can position each one in the best spot in each room.

And, that’s it. It takes us less than a day to install. It’s much more straightforward and much less expensive than other options. And, it works much better than older hvac solutions.

How ductless units create zoned cooling

A significant advantage of a ductless system is zoned cooling. What this means is that each unit cools a different room, or zone, in the home. Every unit has its own thermostat to do the job.

With a central system, there’s usually just one thermostat in the house. It controls the entire home. But, this means the whole home won’t get the same treatment.

Usually, the thermostat is on the first floor. In the summer, it will turn on the ac when the temperature near it is higher than its setting. Then, it turns the ac back off once the temperature is correct again.

But, the whole house is not the same temperature. Often, the upstairs is warmer. But, the thermostat isn’t measuring that area. So, the system shuts off before those rooms cool off.

That’s the difference with ductless. Since each unit has a thermostat, each one works on its own. In the rooms that cool off quickly, those units shut off first. Meanwhile, the others in places that are warmer will keep working until the climate control is just right.

Zoned hvac also offers more flexibility. Our homeowners don’t have to set each unit to the same temperature. For instance, they put a unit in one of their spare bedrooms. There’s not always a person using it. So, they can leave that unit off until someone is using that room.

Ductless units vs. window air conditioners

A ductless HVAC system offers better cooling for less money than window air conditioners. The units use less energy and can cool off a room better than window units. They are also quieter and require less maintenance.

The difference lies mostly in the design. Window ac’s require people to put them in and take them out each year. As a result, they are never really sealed in. That means a good deal of the cold air they produce seeps outside the house through openings in the window.

That’s not the case with ductless, however. Here, the treated air runs through that plastic tubing. It’s sealed well to the condenser on one end and the unit on the other. And, unlike ductwork, there aren’t any leaky spots.

So, the system doesn’t waste much, if any, energy cooling air that doesn’t get used.

And, thanks to the technology in the units, they can produce more cool air using less energy. Since they use less energy than window units, they have a much smaller impact on your electric bills each month.

Finally, the ductless units are permanent and whisper-quiet. Once they are installed, you never have to worry about moving them. And, when they’re on, you won’t even notice. They make virtually no sound at all when they’re working.

All those benefits have a big upfront advantage, too. Since they are energy-efficient, our homeowners qualified for rebates. Two groups in the Bay State, the Massachusetts Clean Energy Center and Mass Save, offer cash incentives for people to install new ac units that use less energy than older ones.

We made sure our homeowners applied for these. And, between the two groups, they received $1,600 toward installing the new system. Between the rebate and the lower monthly energy bills, our homeowners are getting better climate control than ever. And, they’re paying less for it, too.

It’s common to see additions on ranch homes. These one-floor houses became popular during the suburban housing boom of the 50s and 60s. Over time, people began to add more rooms to them.

This ranch in Andover MA, for instance, had a large room added over the garage. It gives the home a split ranch look. The room has high ceilings that just about make it like a second floor.

While this increases the value, it also makes it harder to heat and cool the home. Since it’s an addition, the room was never part of the original hvac design. It gets some heat, but not a lot.

That meant the room never quite warmed up properly in the winter. And, the home didn’t have central air. That meant the room over the garage would get even hotter than other parts of the house.

However, it wasn’t the only trouble spot in the house. The den, where the family watched TV, had many of the same problems: Too cold in the winter, not cool enough in the summer.

So, our homeowners reached out to NETR for a way to fix these problems. They wanted to supplement their system and add air conditioning for the first time. While they knew it would be a big investment, they wanted to get the most for their money.

Fortunately, they called the right place. We designed a custom system using ductless technology for their den and the room over the garage.

The system cost less to install than building new ductwork for heat retrofitting central air. And, it’s more efficient than window air conditioners and space heaters.

Problem: Homeowners in a split ranch in Andover MA wanted better climate control in their den and the big room over their garage. They had oil heat but no air conditioning.

Solution: Installed an outdoor Mitsubishi heat pump with matching ductless units in the den and room over the garage.

Uneven heating and cooling in a split ranch

Uneven heating and cooling is when there are hot and cold spots in different parts of the house. A central system like a gas furnace is supposed to provide an even temperature throughout the home. But, this doesn’t always happen. The result is different temperatures in various rooms.

It’s a widespread phenomenon, especially in split ranch homes. It’s partially because of how the home is laid out. One part of the house has two stories while another has one. As a result, air travels differently than in regular two-story houses.

Here’s what’s happening in this case: The room above the garage is essentially the second story. And, hot air rises. So, as the heat moves up, it collects in the highest point of the home.

Meanwhile, the garage floor is concrete. And, it’s not well insulated. That makes it one of the coolest parts of the home. And, warmth naturally gravitates toward cold air.

So, it’s more than the hot air collecting on the floor above the garage. The garage itself is also attracting heat, which is collecting above it. And, since the den is next to that room, it’s also getting more warmth.

This would be a good thing, except that it collects at the wrong times. In the summer, there’s also sunlight and heat beating down on the roof. Now, that heat gathers in the room above the garage. It’s got no place to go.

As a result, the room above the garage, and the den next to it get really hot in the summer. In the winter, however, the opposite occurs.

This house has oil heat, which warms a home quicker than gas or electric. So, there’s plenty of heat in the house. However, there’s a lot of cold air outside. Now, when the hot air rises it keeps going up. Since there is cold air outside, the warmth escapes through the roof.

The problem here is that the thermostat is not near the garage. When the area near the thermostat is warm, the furnace shuts off. But, the other rooms are still cold because the thermostat isn’t measuring them.

These factors make hvac in a house like this challenging. Fortunately, new technology makes it easier to address.

Adding cooling and extra heat with ductless units

Ductless units offer what’s called “zoned” heating and cooling. That’s because each unit has its own thermostat. And, the system overall is much more flexible than older central hvac solutions.

Instead of traditional ductwork and vents, warmth or cooled air travels through thin plastic tubes. The system starts outside with a heat pump. Then, those tubes are small enough to fit inside walls. Our installers can snake them through the house without having to tear down walls, take up extra space or build expensive ductwork.

At the other end are the units themselves. Our installers find the best spot in each room for them. Since the tubing moves around so easily, we can put the units anywhere we want.

Each unit has enough power to heat or cool a room or two. And, each one has its own thermostat. This where the “zoned” part comes in.

Now, every unit handles one zone. That allows the system to add extra heat or cold air where it’s needed. This way, the entire home is heated or cooled evenly.

In the case of this home, we installed just two units: One in the room above the garage and one in the den. In the winter, they add just a little more warmth when the oil furnace isn’t cutting it there.

And, for the first time, there is air conditioning in these rooms. The units go a long way toward keeping these rooms — the hottest in the house — colder in the summer.

Ductless units save you money on energy bills.

It would seem like adding ductless HVAC untis to this split ranch would make the house’s energy bills go up. After all, the homeowners would have to pay for the extra energy it uses. But, that’s not exactly what happens.For some months, the house will actually use less energy than before. And, the homeowners were eligible for large cash rebates that put a sizable dent in the cost of the new system.

The units are Energy Star-certified. That shows that they use less energy than similar hvac systems to provide the same results. Today, many groups across the country want people to install new energy-efficient models. They’re better for the environment. And, these groups make them better for people’s wallets.

In this case, our homeowners were eligible for more than $2,500 in cash rebates for going ductless instead of using less efficient options. Thanks to the Massachusetts Clean Energy Center and Mass Save, they are paying much less than the listed price for their new system.

And, now, that more efficient heat kicks in, so the oil doesn’t have to. In the fall and spring, the HVAC units alone can provide enough heat for those cold rooms.

As a result, the oil heat, which is more expensive, doesn’t turn on as early in the season. And, it doesn’t have to work as long as it used to in the spring. By using the more efficient system, our homeowners save money on their energy bills.

It’s hard to believe that a home today doesn’t have any sort of air conditioning. But, it may not be as unusual as you may think.

After all, central air wasn’t available in homes until the 70s. And, some people never liked window air conditioners. They’re bulky, loud and cost a lot to run.

For whatever reason, one cape-style home in Andover MA never had any ac. But, the homeowner was finally ready for a change. And, she wanted to make the best investment possible.

Our homeowner called NETR after reading all our outstanding customer reviews. And, she had a few options. Central air was one. But, that would require a lot of work, and a lot of money, to design and build new ductwork for the home.

There are also portable and window ac’s. But, these are not very efficient. Plus, they take up a lot of space and use a lot of energy. She didn’t want her electric bill to skyrocket in the summer.

Fortunately, there was a great solution for this home: A ductless mini-split system. It provides the strength of central air with the zoned effect of window or portable units. And, it would work better and cost less than either of those options.

• Problem: A cape-style home in Andover MA did not have air conditioning. The homeowner wanted cooling in the main living area, master bedroom and home office.

• Solution: Installed a Mitsubishi outdoor mini-split outdoor condenser and three ductless units inside the home.

Ductless HVAC vs. central air conditioning or window ac units

A ductless hvac system can cool a home just as well, if not better, than central air. It’s just as strong and can cool the entire house. However, it’s not one-size-fits-all like a central unit.

There are a few major differences. First, the cold air does not travel through ductwork as it does with a regular central air conditioner. Instead, this system uses narrow, flexible tubing that runs from the condenser to the indoor units.

That makes a big difference. The tubing is so small that our techs run it through the walls without altering anything. That means no new ducts and no tearing down walls. We have the whole system installed in less than a day.

What makes the system similar to window units is that there are units in various rooms. It's different from using vents. But, the similarities stop there.

For starters, the units are whisper-quiet. Unless you have your ear up to it, you’ll never hear it working. It's a significant contrast from the constant roar of a clunky old window air conditioner.

The units also stay in the room all the time. Once they are mounted, they never come down. Usually, they are set high up on a wall where you rarely notice them.

This setup makes using them a lot easier. You don’t have to drag around the units each spring to clean and install them. Our techs put them up once, and you don’t have to worry about them again.

Creating zoned HVAC with a Mitsubishi ductless System

We mentioned before that the ductless system is not “one-size-fits-all” like central air. By creating hvac “zones,” they avoid hot or cold spots in the house.

Each unit has a thermostat on it. A central unit, on the other hand, has just one thermostat for the entire house.

When there’s one control, the system cools the entire home at the same time. That means if one area — usually the upstairs — takes longer to cool, it won’t get properly treated. The ac turns off when the room with the thermostat reaches the desired temperature.

That’s not so with these units, however. Instead, each one works apart from the others. If one room takes longer to cool down, that unit stays on until it does the job. Meanwhile, other units turn off sooner.

This system offers much better climate control. With central air, the basement could get too cold, or the bedrooms are always too hot. Now, our homeowner sets each room to the temperature she wants.

That means the temps can also be different for each zone. For instance, perhaps our homeowner prefers her bedroom much cooler than the living room. She can set each unit differently than the other. Or, she can adjust them all the same for nice, balanced climate control.

How a Mitsubishi mini-split system saves you money

A Mitsubishi mini-split system doesn’t just work better than central air or window ac units. They also save you money on your monthly utility bills. The savings occur because the system uses less energy to achieve the same — or better — results.

Part of this is just due to better technology. The condenser and indoor units simply work better than older options. As a result, the mini-split system is Energy Star-certified, showing it uses less energy than similar setups.

Next is the tubing through which the air travels. It seals up much better than ducts. That means they lose less cold air along the way. Ductwork, by design, lets some of that treated air leak out.

Finally, there’s the zoned aspect. Remember, our homeowner can set each unit to a different temperature. Well, she can also leave some on and some off.

Splitting them like that is a common tactic. If our homeowner will be downstairs all day, for instance, there’s no reason to keep cooling the bedroom. Then, the opposite happens at night: she can turn off the units downstairs.

Doing so uses less energy. And, the less energy our homeowner uses, the less she pays for each month.

In fact, our homeowner’s new system is so efficient that she got a cash rebate just for installing it! Today, energy companies offer incentives for people to install hvac units that use less energy than older ones.

We found one in her area called Mass Save. It’s a collaborative of utility companies in the Bay State that offer rebates for Energy Star units. Since this one fit the bill, we made sure our homeowner applied for it.

As a result, she got a $300 rebate toward her installation. The cash brought the cost of her unit down even further. Even though it’s the first time she has air conditioning, she’s paying much less each month for it. And, the ac she’s getting is even better than the more expensive options.

It was time for an hvac upgrade in this Andover, MA colonial home. The homeowners were paying way too much on their electric bills to heat and cool their home. And, the system they had didn’t even work that well.

The house had electric heaters for the winter and window air conditioning units for the summer. Neither are very effective. They take a while to take effect, and they don’t treat the whole house properly. Meanwhile, however, they cost a lot to run.

Our homeowners were ready for a change. They knew it would be a big investment. But, they couldn’t see going through another year of high energy bills and sub-par climate control.

So, our homeowners called NETR after reading our outstanding customer reviews. They felt comfortable that we could create just the right system for their home. And, we did

• Problem: A colonial home in Andover MA had high energy bills in the winter and summer. The homeowners used electric heat and window air conditioners. The window units were noisy and were a hassle to install and remove each year.
• Solution: Installed a Mitsubishi Hyper-heat mini-split outdoor heat pump and condenser with five high-wall indoor units.

More efficient hvac with a Mitsubishi ductless system

The main problem this home had was an outdated hvac system. Maybe a few decades ago, electric heat and window air conditioners were sound choices. Now, however, there are much better products available.

First of all, electric furnaces take a while to heat up. That creates a lag from when it kicks on to when you actually feel your home warm up. Meanwhile, a one-zone hvac setup just isn’t the best option anymore.

In most homes, there's only one thermostat controlling the furnace. The thermostat is usually on the first floor of the home. But, there’s a problem here: The whole house does not warm up the same way at the same time.

Many times, the upstairs rooms are much colder than downstairs. But, the thermostat will shut off the system once the first floor reaches the desired temperature. This leads to hot and cold spots in the house.

Meanwhile, the window air conditioners in the summer posed different problems. These units are not very efficient. They use a lot of electricity to cool a room. That causes electric bills to skyrocket during the hottest months.

They also waste a lot of energy. That’s because they are never permanently installed. The homeowners need to drag them out of storage and put them in the windows every spring.

This process becomes a hassle over time. And, since the window ac's are never fully installed, they aren’t sealed in. As a result, a lot of the air conditioning escapes around the unit and goes outside.

And, if that wasn’t enough, the air conditioning they do provide comes with a dull roar all day long. Window units are notoriously loud. Some people prefer that sort of white noise when they sleep. But, others don’t. And, just about no one enjoys that noise when they’re trying to talk, watch TV or listen to music.

So, it was time for an upgrade. And, the solutions to all these problems was a Mitsubishi mini-split system. It costs less to run and provides “zoned” heating and cooling for better, customized comfort.

What is zoned heating and cooling?

Zoned heating, is when a home has multiple hvac units. It's different from having one centralized heater or ac. With zoned, each unit handles a different “zone” in the house. Now, the homeowner to create more even heat or air conditioning. It can also save money on energy bills.

Here’s how it works with ductless mini-splits: Here’s how it works: An outdoor heat pump generates the warm air or ac. That treated air works its way through the home through small, flexible tubing. The tubing much smaller, and more efficient than old-fashioned ductwork.

At the other end are the indoor units themselves. Each one handles a different room, or zone, in the home. And, each one has its own thermostat. It makes the system much more flexible than a regular one-zone system.

Now, every indoor air handler works on its own. If one room takes longer than others to warm up, that unit stays on longer than others. And, in the summer, they cool the home just as evenly.

This eliminates all those hot and cold spots in the house. Now, each indoor unit ensures every room is just the right temperature.

Do ductless mini-splits save money on heating and cooling costs?

Compared to other hvac sources, a ductless mini-split system with a heat pump costs less to run. This is due to the technology they use and the way they are set up. They use less energy than gas, electric, or oil. And, the system doesn’t waste as much of that energy as other options.

The savings start outside, with the heat pump. These use electricity to run, but not to generate the hot or cold air. They need a little to get the system working. The actual climate control takes place thanks to a heat transfer process.

Without getting too technical, the system draws what little warmth there is outside in the winter. It uses a condenser to magnify it, and then send the heat into the house. In the summer, it draws warm air from the home, cools it, and sends it back in.

It works in a closed system where all it’s actually doing is transferring heat, not generating it. Therefore, it costs a lot less than a furnace to run. Inside the home, the treated air travels through tubing that is more secure than ductwork. This setup means less hot or cold air gets lost along the way.

Meanwhile, the minis-splits use less energy than other options. This is partly because they all won’t run as much. Remember, each one shuts off when its zone reaches the right temperature. As a result, the system doesn’t stay on longer than it should, as it would with a one-zone system.

For these reasons, the mini-split system our homeowners chose is Energy Star-certified. It meets government standards showing it uses less energy than similar units.

That also amounts to upfront savings. In the Bay State, two energy conservation groups offer cash incentives for people to install energy-efficient units. We made sure our homeowners applied for these.

As a result, they received a $2,500 rebate from Mass Save and another $625 from the Massachusetts Clean Energy Center. That money put a huge dent in their installation costs. And, now they are paying less every month on their electric bill.

It’s rare that spending less money gets you better results. But, with mini-splits, that’s precisely what happens.

Heating and cooling a large, two-family home can be a big expense. There a lot of ground to cover, and these homes usually do not have great airflow. Plus, there are two separate families with different needs in the same home.

This home in Somerville, MA had an outdated HVAC system. There was a furnace with gas heat that didn’t warm the house properly, leaving some rooms cold. 

The home, also, did not have central air. The tenants used window unit air conditioners in the summer, but they were noisy and drove up the electric bills.

So, it was time for an upgrade. The property owner wanted a new system that was energy-efficient, quiet and did not need a lot of upkeep. After reading ductless mini split system reviews, the owner knew it the mini split units were the right choice. It would be a big investment, but his tenants would be more comfortable, and it would save him money in the long the run.

Problem: A two-family home in Somerville MA had uneven heating and used inefficient window air conditioners in the summer.

Solution: Installed a Mitsubishi ductless mini-split unit with an outdoor heat pump and four ductless units in the house.

Zoned HVAC Creates Better Heating and Cooling

One reason the house wouldn’t heat properly was that the HVAC system treated it as one zone. That means the entire house was controlled by one thermostat, which is far from ideal for a multi-family home.

This type of system only read the temperature in one area of the house, even though the temperature throughout the house may vary from room to room. When the room with the thermostat was too cold, the furnace kicked in, but it stopped when that room reached the setting.  However, other areas of the house weren’t warm yet and since the furnace off again, it never reached the desired temperature. 

Therefore, a single zone unit is highly inefficient at heating such a large home, but this can happen in a home of any size. That wasn’t the only problem.

Heat usually travels between rooms and through stairwells; however, these are blocked off in a two-family home. Restricting the airflow prevents the entire home from warming properly.

Having only one thermostat meant that one apartment controlled the climate for the whole house. That’s a problem if another tenant wants it cooler or warmer. And, it’s especially frustrating if their apartment doesn’t even get as warm as the one with the thermostat.

Our Solution

The solution is to break up the house into zones and we did this with a ductless mini-split system. These are simple to install and easy to customize.

This system starts with an outdoor heat pump. The mini split unit produces the warm or cool air that will circulate in the house. That air travels into the home through small, plastic tubing.

On the other end are ductless units. They’re long, rectangular units that our installers can mount just about anywhere, but the best spot for them is high up on a wall. The tubing runs through the walls and attaches to the unit.

Unlike a central system, each unit handles one “zone” of the house and each unit all has its own thermostats. This way, they can turn on and shut off independently from each other.

Now, if they are all set to the same temperature the house will be evenly heated. Or, the tenants can heat each one separately and one apartment doesn’t control the entire house.

Ductless Versus Window Unit Air Conditioners

Another advantage of the ductless mini-split system is an improvement in cooling during the summer months. Ductless air conditioning offers the best of both worlds. It packs the power of a central air unit and it’s as flexible as using window unit air conditioners.

The same units that deliver heat in the winter also cool the apartments in the summer. Thanks to new technology, they can treat the rooms quickly and maintain that temperature.

There are some big differences between window units and ductless cooling. First, ductless heat and air units are whisper quiet. Now the tenants won’t have to put up with the constant dull roar of their AC just to cool down.

Next, ductless mini split units do a better job because they are permanently installed. Window AC’s are made to be installed in the spring and taken out in the fall, which means there is never a good seal around them. A lot of cold air escapes without doing the job.

With ductless mini split systems, the units are completely in the room. They’re just as powerful as a central air unit and, unlike a one-zone setup, each unit's thermostat can be set for cooling or heating.

This system makes it easy to keep the second floor just as cool as the first one. Since hot air rises, it’s common for the second story of any house to be warmer than the rooms below. Now, each tenant can set their own temperature.

And, they can set each unit to a different setting if they want. This goes a long way toward keeping the bedroom the perfect temperature for a great night’s sleep.

Saving Money with a Ductless Mini-Split System

Overhauling the HVAC system for an entire house is a big investment. Fortunately, the new ductless mini-split system in this home is energy efficient. This helped the property owner spend less up front when he had it installed, and it will save him money every month.

The energy efficient ductless units use less energy to produce the same results as other systems that use more resources like natural gas or electricity. And, the less energy the home uses, the smaller the monthly utility bills.

For this heat pump, its efficiency shows in its HSPF and SEER ratings. These stand for “Heating Seasonal Performance Factor” and “Seasonal Energy Efficiency Ratio.”

Put very simply. HSPF measures how much electricity it takes to produce a unit of heat. The SEER does the same for cool air. The higher rating the less energy it takes to produce the warmth or cool air.

For a unit to be considered energy-efficient, it needs at least an HSPF rating of 8.2 and a 15 SEER rating. This heat pump ranges from a 9.8 to 11.3 HSPF rating and 17 to 19.1 SEER rating. For reference, those old window AC’s had SEER ratings around 10.

So, each month, the home is using less energy for climate control. That means big savings over time on utility bills for the property owner.

Great Rating Equals Instant Savings

Those great ratings also resulted in instant savings. In Massachusetts, property owners can qualify for cash rebates for replacing old furnaces and air conditioners with energy efficient ones. By using less energy, the new ones are better for the environment.

In this case, ductless heat and air systems are also better for the owner’s wallet. We helped him apply for rebates from two energy groups. In all, he got $3,000 in cash just for putting in his new system.

The owner of a multi-family Victorian-style home in Somerville, MA wanted to upgrade the HVAC system in their home. The energy bills for the house too high, but he didn’t want to make a lot of physical changes to the home since it was in a historic district.

The home already had steam gas, but no central air system. His tenants used window air conditioners in the summer and house’s structure caused it to use more energy heating and cooling than similar homes.

Of course, upgrading the whole system would be a big investment. So, the property owner wanted to make the most of it. This meant getting a system that offered better climate control and lowered monthly expenses. It also needed to be low-maintenance and easy to use.

After reading our outstanding reviews, the property owner called NETR. We quickly got to work designing a system that met all his needs.

Problem: A multi-family Victorian house in Somerville MA needed an HVAC upgrade. The steam gas heat did not evenly heat the entire home. The window air conditioners cost too much to run in the summer.

Solution: Installed a new Mitsubishi ductless HVAC system. The custom design uses indoor units in the living room, dining room and bedroom with an outdoor hyper-heating outdoor condenser unit.

Ductless Units are Easy to Install

We designed a ductless system for this home. Like the property owner wanted, it used less energy than his old HVAC system and is easy to use. But, that’s not all this system was ideal for a historic house, because ductless AC units don’t require a lot of work to install.

Traditional, central systems require ductwork and vents. This often means a certain amount of construction in the house. In order to install new vents and ductwork, installers may have to modify floors and walls. This can take away from the visual appeal of any home. It also takes up space, especially when they need to fill closets or other spots with ducts.

Older homes weren’t designed to have all that duct work in them. As a result, they often need more work than modern homes. Fortunately, we were able to bypass all of that thanks to how the ductless system works.

These units don’t push air through big, bulky ducts. Instead, the forced heat or cool air travels through plastic tubing. The tubing itself is very narrow, just a few inches wide and flexible.

The flexibility lets our installers run it like electrical wiring. It can be snaked through the house without tearing open any walls or floors. The ductless system is much less invasive than traditional units.

The treated air itself comes from an outdoor condenser unit, similar to a central air unit, but thinner and less noticeable.

From the outdoor unit we drill a small hole through the wall and feed the tubing thourhg to run the heat into the house.  Inside the house are rectangular units that sit high on a wall. The tubing attaches to them through another small hole that’s covered by the unit itself.

Once everything is hooked up, the system is ready to go. It’s an easy process that takes less than a day in most cases and doesn’t have nearly as much impact on the visual appeal of the house as most other systems.

Ductless Units Offer Even HVAC

Once installed, ductless units offer better heating and cooling than older systems. One reason is that the newer designs allow them to distribute the air more efficiently than models that were invented decades ago.

The flexibility also plays a role in their efficiency, since the units can be easily mounted anywhere. Our installers can find the ideal spot in any room for them. This allows our installers to locate the optimal place for every unit to increase their efficiency.

Instead of being controlled by one thermostat, each unit works independently. They can all be set to the same temperature or put at different settings so that every room stays the perfect temperature. This helps the units use less energy than with a centralized system.

When they are all set for the same temp, each unit will work until its designated zone reaches the desired temperature and then it will shut off. This way the only units running are the ones that need to be at any given time.

In the winter, the units in the rooms that warm up quickly will turn off before the cooler rooms will. That means they use less energy — and cost less money.

Since the units are separate, they don’t have to be set the same. If one tenant doesn’t need the kitchen as warm as other rooms, they can lower the temperature in that room. If another tenant wants the bedroom a few degrees hotter than other spots, now they can program each unit on its own.

Ductless HVAC Saves Money on Monthly Bills

In almost every case, the units are more energy efficient than old ductwork-and-vent setups and they are always better than window air conditioners. This is proven through their Seasonal Efficiency Energy Ratio, or SEER, ratings.

A SEER rating measures how much energy an AC unit uses to cool an area. The higher rating, the less energy it uses, and less energy means less spent monthly utility bills.

The new units offer much more efficiency than the old units. Window air conditioners often have SEER ratings around 10. Today, all central air units must have a rating of 13 or higher.

There are also Energy Star ratings. In order to be certified for Energy Star, an appliance must show that it is more energy efficient than other units that do the same job. Air conditioners need SEER ratings of 14.5 or higher.

So how does the new Mitsubishi ductless system stack up? Under the right circumstances, its SEER rating is 23.2. That’s way more than the old units and more than even the average central air system.

The comparison isn’t the same in the winter. The home still has oil heat and the new system only supplements that instead of replacing it.  However, the house will now use less oil throughout the year.

As we mentioned before, the HVAC units go a long way toward even heating. Now, there’s no need to waste extra energy for the whole system to heat up a few cold spots.

The new units make it so the expensive oil heat system will not have to be used nearly as often.  Heating with just the units in the fall and early winter will do the trick now. The same goes for those warm, early spring days!

Of course, installing the new system is a large investment for a house this big. Fortunately, this homeowner was able to cash in on some huge savings thanks to a rebates that NETR was able to help them find.

In the Somerville area, two groups offer rebates for installing high-efficiency equipment. One is Mass Save, a collaborative of utility companies in the state. The other is the Massachusetts Clean Energy Center.

We made sure our property owner knew about the rebates and how to apply for them. Between both organizations, he received more than $1,600, which really helped to offset his installation costs!

Our property owner also took advantage of our financing offers. Now, he’s set up with zero interest over 72 months.

Our payment plan along with the rebates made this HVAC investment an easy decision. Add to those benefits all the money he’ll be saving in monthly energy bills and it makes it all a small to price to pay — literally — for great climate control.

It was time for a change for this two-family colonial home in Somerville MA. For years, the house had an oil furnace and no central air. While there was plenty of heat, it wasn’t spread out evenly and some of the rooms never got warm.

Meanwhile, summers were too hot. Both apartments had to use window air conditioners, but they are noisy and required a lot of maintenance. Finally, both the heating and cooling systems were expensive to fun.

These homeowners were ready for a completely new HVAC system and they wanted something was energy-efficient, quiet, easy to use, and low-maintenance. In addition, the new system also needed to treat the whole house evenly.

That all sounds like a tall order. But the homeowners knew just where to look. They came to NETR after reading our outstanding reviews. We were able to design and install a system that met all their needs — and lowered their monthly energy bills.  

Problem: The energy bills in a two-family colonial home in Somerville, MA were too high, and the climate control was uneven across the apartments.

Solution: NETR installed a Mitsubishi ductless HVAC system. The custom system uses three units on the first floor, two on the second floor, and an outdoor HyperHeat heat pump unit.

Uneven and Inefficient Heating and Cooling

In order to create the best new HVAC system for this home, we had to look at what was wrong with the heating and cooling systems in the house currently.

When it came to heat, strength wasn’t the problem because oil heat burns very hot.  As a result, it can quickly heat up an area and often works even faster than gas or electric heat.  However, spreading that forced hot air evenly can be tricky, especially in a two-family home.

One issue is the “stack effect.” It’s well-known that hot air rises, but it does so by “stacking” from the heat source and then moving up. This means parts of the house will heat up quicker than others and the heat that makes it to the top floor will then continue out of the house through any openings or drafts.

There’s also the problem of airflow. One common problem in a two-family home is that the stairwells are not open. In a single-family house, an open stairwell would allow the heat to move freely, but here it gets into some places while not reaching others.

All this worked against the power of oil heat. Even though this energy source could warm a large space quickly, the airflow in the house prevented it from heating the entire home evenly.

The problem in the summer was much simpler: window air conditioners are inefficient and noisy. Plus, they use a lot more energy than central air and require a lot of maintenance.

Ductless Units Offer Heating and Cooling

A great way to address all these issues at once was to install a ductless split system for zoned HVAC. This means you can adjust the temperature in different parts of the home individually, instead of having one thermostat to control the whole house.

Here’s how the new system works: an outdoor heat pump provides forced heat or cool air. The treated air travels through tubing in the walls that connects to the units in the home.

The units are mounted wherever they’re needed in the home and each one treats a different “zone” in the house. Every unit is then controlled by its own thermostat.

This makes a huge difference in this situation where the problem wasn’t the oil heating system could produce enough heat, just that the heat couldn’t reach every part of the house.

Now, those hard-to-reach areas have their own ductless units to make sure they are always the perfect temperature. Instead of turning up the heat higher than it needs to be, the units pick up the slack.

In the summer the system works the same way. Each unitcools a different zone in the house, but unlike the old window units the units are whisper-quiet.

The new ductless units also cool each room faster than the old ACs and use less energy to do the job.

Saving Money with Ductless HVAC

Because of these energy efficient units, our homeowners got money back for their upgrade!  They were able to get money back thanks to Mass Save and the Massachusetts Clean Energy Center.

These two groups advocate for clean energy and energy-saving products. One way they do this is by offering cash rebates for anyone who installs energy-efficient products. We made sure our homeowners were aware of these savings and even helped them apply for the rebates.

As a result, our homeowners got more than $1,700 in cash rebates for the installation. $200 came from Mass Save and the Clean Energy Center offered $1,502.

On top of those upfront savings, they are saving money on their monthly energy bills.  

Now they’re no longer using clunky old window air conditioners in the summer and the new system will use much less energy to do the job. 

Because window units are meant to be taken in and out the cooled air escapes around the unit because the area often isn’t sealed well. This won’t happen now because the units are entirely inside the home.

In the winter, they won’t have to crank up the heat because new system supplements the oil heat. This allows the tenants in each apartment to keep the oil heat a little lower and let the units take care of the extra warmth a few of the rooms need.

Now, the tenants don’t need to turn on the heat when it starts getting chilly and they can turn it off earlier in the year because the units will be able to keep the house a comfortable temperature by themselves. So, these homeowners will use their oil heater less overall!

Instead, the more efficient units provide enough heat in the fall to keep them warm before the temperatures really drop.  As soon as it gets a little warmer at the end of winter, they can switch from oil heat to the units.

Using less oil, of course, keeps their energy costs down and when combined with the summer savings, they’re paying less all year ‘round.

A new addition to a home needs heating and cooling just like every other part of the house. A ductless heating and cooling system makes that process much easier and much more efficient than other options.

Our homeowners had just added a new room off the kitchen of their large colonial home in Carlisle, MA.

Now, they would need supplemental heating to handle that part of the house. Meanwhile, the house did not have central air and the homeowners used window air conditioners in the summer.

Ready for a fresh start with their new addition, our homeowners called NETR. They’d read our outstanding reviews and saw we are the number-one Elite Diamond Dealer in New England.

We quickly got to work designing the perfect electric ductless mini split system for their home.

Problem: A colonial home in Carlisle MA needed cooling and supplemental heating for their kitchen and a new addition to their home. The house had oil heat and no central air.

Solution: Installed a Mitsubishi electric ductless mini-split system with an outdoor condenser and two indoor ductless units.

Ductless HVAC in a New Addition

There are many advantages to installing a ductless HVAC outdoor unit. These benefits have an even bigger impact on a new construction.

Much of this has to do with how the ductless split system works. As the name implies, it doesn’t require ductwork to operate. This means our installers don’t have to map a route for ductwork, then build and install it. Meanwhile, our homeowners don’t have to pay hundreds, if not thousands, for the additional labor.

With a Mitsubishi electric ductless system, an outdoor condenser provides the warm or cool air. That air travels through small, flexible plastic tubing, which is about two inches in diameter. Therefore, our installers can feed it through a wall. This is much simpler — and cheaper — than designing and installing ducts.

Finally, that tubing connects to a ductless unit where the air is distributed into the room. The tubing itself comes through the wall behind the unit and connects to it.

Since the HVAC unit doesn’t require a vent, out installers can place it anywhere in the room. This allows us to find the best spot for optimal performance. Each unit comes with a remote control, so the homeowners can control the temperature, even if the unit itself is installed out of easy reach.

This makes ductless HVAC perfect for this new addition and one less thing for our homeowners to worry about. They can design the room however they want and adding the ductless unit will be little more than an afterthought.

Ductless Cooling Replaces Window Units

The electric ductless system in this home also handles air conditioning. The units are a huge improvement over the old window air conditioners the homeowners previously used.

Window units are commonly used in an old house like this. Central air wasn’t available in most homes until the 70s and it can be expensive to install it later.

Once again, the ease of putting in a ductless system was a big benefit. Installing central air means, at least, tapping into existing ductwork and, often, new ducts. That would certainly have been the case in the new addition.

Instead, the same ductless units that provide heat in the winter also provide cool air in the summer and they do it faster and quieter than the window units.

Thanks to the technology in ductless units, they are whisper-quiet. This is very different from the old, loud AC’s the home had previously. In addition, unlike the window units these don’t require a lot of maintenance.

In the past, our homeowners had to spend a day taking out the window units from storage. They’d have to clean them out and maybe get them fixed. Problems like broken coil and low refrigerant coolant are common in window units over time, but this is not so with ductless units.

Saving Big with Ductless Heating and Cooling

Convenience and great climate control are huge benefits of a ductless HVAC system. For many people the cost is just as important. The systems we install deliver on that just as well.

An electric ductless mini split system is a big commitment, but it’s one that pays for itself over time by lower monthly energy bills.

Ductless units, on average, use less energy than other HVAC options to work. There’s also the zoned aspect of ductless units. There’s also the zoned aspect of ductless panels.

Each has its own thermostat, which means our homeowners can control each unit separately. This is very different from an oil burner using one thermostat for the whole home. When there’s one thermostat, the system turns on and off just based on the temperature in that area.

Even if other parts of the home heat up before that spot, the whole house continues to get warmer until the thermostat hits its mark. This results in the system using more energy than needed.

With a ductless unit, our homeowners can customize them to use less energy. For instance, if the kitchen gets warmer before the new addition, then that unit can turn off before the one in the new room. 

It also means the homeowners can wait an extra few weeks to turn on their more expensive oil heat in the fall. Instead, they can use the more efficient ductless units for just a little bit of heat. Then, they can fire up the burner when it really gets cold.

All this made the new ductless units the finishing touch for this home’s new addition. The units give the home a state-of-the-art HVAC system that uses less energy and provides more comfort than they had before.

Sometimes, even the best heat can’t quite warm a home well enough. That was the problem our homeowners in Concord, MA were experiencing.

Their ranch home had oil heat coming through baseboard heaters. And, even though oil burns hotter than other heat sources, parts of the home were still too cold. But, this was due to the HVAC layout, not the heat itself.

Older homes like this one often have outdated HVAC systems. Technology improved greatly over the past few decades. As a result, people know they can get better results for less money with upgraded systems.

These homeowners also had a problem in the summer: The house was too hot. For years, they’d used window unit air conditioners to cool off a few parts of it. That’s because the home was built before central air was widely available in homes.

These could all be solved with a major HVAC overhaul. But, that would be expensive and require construction in the home. Instead, the homeowners wanted a solution that would be easy to install, easy to use, and easier on their energy bills than what we had now.

They chose NETR to come up with a solution for them. After reading our outstanding products reviews, they knew we could provide an efficient and cost-effective supplemental heating solution for them.

Problem: A family with a ranch home in Concord, MA had could not get the family room and master bedroom warm enough in the winter with oil baseboard heat. They used window air conditioners instead of central air in the summer.

Solution: Installed a Mitsubishi Comfort ductless heating and cooling split system with units in the family room and master bedroom leading to an outdoor condenser unit.

Ductless Heating Supplements Baseboard Heat

Installing a ductless HVAC system was the best way to address everything this family needed. It provides supplemental heating and replaces inefficient window air conditioners. And, it does not require a lot of work on the home.

Dual zone ductless heating and cooling does all this thanks to its design. As the name implies, it doesn’t require big, bulky ductwork to deliver climate control. This allows our installers to place the system wherever it will work best. They don’t have to worry about using existing ductwork or doing major work to install new ducts and vents.

Ductless heating and cooling systems starts outside with a condenser unit. This is the part of the system that provides the heat in winter and cool air in the summer. That heat or cooling travels through very narrow, flexible piping instead of ductwork.

This is a big difference. Instead of metal ducts usually more than a foot wide, the piping is less than three inches in diameter and is flexible. This means our installers easily run it through rafters and in between beams in your walls.

Finally, that piping attaches to ductless units. Installers can mount the unit anywhere because it doesn’t require a vent. So, they can find the best spot in any room. Usually, that’s high up on a wall, mostly out of sight.

The unit itself covers the very small hole where the piping comes through the wall. And, each Mitsubishi wall air conditioner and heater has a remote control, so you don’t have to reach up to change the temperature or turn it on or off.

What Are Ductless HVAC Systems are Useful For?

A split system heat pump is especially useful for supplemental heat. Since oil has a very high flash point, it can heat a home quicker than gas or electric systems. However, the baseboard heaters in this home didn’t do a great job of moving that heat around.

Now, our homeowners can use the dual zone ductless heating and cooling system along with their oil heat. It can give just a little extra heat in the rooms that need it. Otherwise, they’d have to turn up the heat in the whole house just get the living room and master bedroom as warm as they wanted it.

Why Ductless HVAC Is More Cost-Efficient Than Window Air Conditioners

Ductless HVAC also goes a long way in the summer. And, it does so for many of the same reasons that make it so useful in the winter.

This is thanks to the “zoned” aspect of ductless heating and cooling. Unlike a central air system or even a furnace, ductless HVAC units don’t work from one thermostat. Instead, eachunit has its own.

Now, our homeowners can set the temperature in each room, or zone differently. In the winter, this means they can customize the heat everywhere to make sure the whole home is evenly heated. In the summer, they can use this to cool off just the parts of the house that need it.

Of course, that’s kind of like how window air conditioners work. After all, each window unit works by itself. But, those a/c’s are old, noisy and inefficient. Ductless unitscan cool better, faster and for less money.

There are a few reasons for this. First, the technology is better. Window units, especially older ones, just can’t deliver as much cool air as the ductless HVAC units while using as little energy. Ductless units are also whisper-quiet. This contrasts with the dull roar that old window units often make when they’re working.

Also, the area around them is usually not sealed.  This allows cool air to seep outside instead of staying in the room. Instead, ductless units are completely indoors. That cool air stays in the room and doesn't go out the window.

Saving Money with Ductless HVAC

All these points show the convenience of ductless HVAC. And, they explain how well they provide climate control. But, there’s one more big part of a ductless system: saving money.

This dual zone ductless heating and cooling system especially goes a long way toward lowering this family’s monthly bills. And, it does so in quite a few ways.

First, there’s the increased efficiency. As we mentioned before, our ductless system uses less energy than other systems to provide hot or cool air. That includes the oil heat and window a/c’s this ranch home had. Using less energy each month means lower monthly energy bills.

Our homeowners also see a lot of savings in the fall and early spring. Since oil heat burns very hot, it can be a little bit of overkill outside of the winter.

Other Options

Now our homeowners have a better option when the weather begins to cool or just begins to get warm. They can wait a few extra weeks in the fall before firing up their oil heat. And, they can turn it off a few weeks earlier in the early part of the year. Using their ductless heat in those weeks will cost them much less than burning oil.

Finally, there’s the zoned part. Remember, each ductless unit has its own thermostat. This means our homeowners can turn down one unit when they don’t need it while turning up another when they do.

For instance, now they don’t need to heat both the living room and master bedroom at night. When they’re sleeping, they can turn down the unit in the living room because no one’s using it. Less energy, once again, means lower bills.

The opposite happens during the day — or in the summer. When it’s warm during the day, our homeowners can cool off the living room much more than the bedroom. Then, when it’s time for bed, they can turn up the bedroom unit to make it cooler.

Ranch homes became popular across the country a few decades ago. But the truth is, they’re not exactly suited for all seasons. And, heating and cooling technology has improved a lot since many of them were built.

Our homeowners in Lincoln, MA found their ranch-style home feeling a little obsolete when it came to HVAC. A few of the rooms were always too cold in the winter. And, the house did not have central air conditioning.

It was time to upgrade the heating and cooling. The homeowners wanted a new system that would use less energy and save them money. They chose NETR after reading our reviews. They saw how we rated outstanding when it comes to energy efficiency and cost-effective heating and cooling units.

Problem: A ranch-style home in Lincoln, MA had no central cooling and needed more heating in the family room and master bedroom.

Solution: Installed Mitsubishi wall mounted ductless air conditioner. The living room and master bedroom each got an indoor air conditioning unit, which attached to an outdoor condenser.

HVAC in a Ranch Home

Ranch homes first began popping up in the southwest part of the country. As a result, they’re best in warmer climates. In cooler areas, they begin to have some problems.

A big one is heat loss. This occurs for a few reasons. First is the layout. A ranch is usually one story. As a result, it’s more spread out than two- or three-story homes. This means it uses more foundation concrete than homes will smaller bases.

But foundation concrete does not insulate well. As a result, most of them were built on slabs that were not insulated. This creates a heat sink because concrete can absorb a lot of heat. It’s an effect that can chill a home in the summer. That’s great for the hotter southwest, but in New England, it’s a problem in the summer.

Other aspects of a ranch allow it to lose heat. These homes often have many thermal passes. Chimneys, recessed lighting and plumbing chases amount to openings in the structure. Heat can escape through these.

In this case, the master bedroom and living room were often too cold. They had oil heat, which heats quicker than gas or electric. But, that even wasn’t enough for this New England ranch.

And, it was an older home, built before central air was popular. The owners were using window units in the summer. But, they weren’t really cutting it.

Our heating and cooling solution had to overcome many big challenges. We couldn’t change the foundation, obviously. Nor did the homeowners want to do any major work. That would include running ductwork for central air.

Fortunately, we knew how to provide the extra heat and powerful cooling the homeowners wanted.

Wall Mounted Ductless Air Conditioner Solves the Problem

A wall mounted ductless air conditioner that also functioned as a split system heat pump was clearly the way to go in this case. This would allow us to add powerful heating and cooling exactly where they needed it. And, we could do so without a lot of extra work.

The trick to it is the ductless HVAC units. These take the place of old-fashioned duct work and vents. Where ducts are big and expensive to install, these units take up almost no room. And, connecting them to an outdoor unit is very simple.

Here’s how it works: Hot or cool air comes from a heat pump outside the home. This is like how a central air conditioner condenser sits outside. However, that air travels through very skinny piping.

The piping is less than three inches wide. And, it’s flexible. This is much different from metal ductwork that’s at least a foot wide. With the piping, our installers don’t have to take up a lot of space in the home to make a path for the air. Planning those paths and building the ducts cost a lot of money.

Ductless HVAC installation

For ductless HVAC installation, all we have to do is drill a small hole in the side of the home and run the piping from the heat pump. From there, they feed it through the walls. Finally, they bring the piping into a room through another small hole.

The piping attaches to the ductless unit. This is the device that actually distributes the hot or cool air. It mounts high on a wall and covers the hole for the piping. The units are whisper quiet. There’s no sound like when a furnace kicks on or a radiator hisses.

Perhaps the biggest difference, sound-wise, comes in the summer. They’re a huge change from the roar of the old window air conditioners the homeowners were using. Before this, it could actually be hard to hear a television in the living room or hold a conversation in the bedroom. Now, they don’t even notice when it’s on.

Of course, the sound isn’t nearly as important as the savings. And, that was the big selling point for the ductless system. Now, the homeowners will get better heating and cooling — and spend less to get it.

Saving Money with Ductless HVAC

Our homeowner’s new Mitsubishi ductless mini split AC system will save them money in a few ways. The biggest savings will come in the summer. That’s because our homeowners are getting rid of their old window air conditioners.

Window units use much more energy than our ductless system. If you’ve ever used them, you’re used to seeing your electric bill skyrocket in the warmer months. But, that won’t happen now.

Thanks to better technology, the ductless units use much less energy to get the same amount of cool air. The new system is Energy Star-certified. It meets government standards proving it’s more efficient than other, similar HVAC options.

In the winter, the savings won’t be quite as big. That’s because the house still uses oil heat through baseboards. But, now our homeowners won’t have to use as much oil to heat the whole house. This is thanks to the zoned HVAC strategy the ductless units offer.

What this means is that each ductless unit handles a different area, or zone, in the home. And, each unit has its own thermostat. This way, our homeowners can set each zone to a different temperature if they want.

They may actually prefer one room cooler than another during part of the day. Now, they don’t have to pay more money to heat it they whole time.

Or, they can set each thermostat to the same temperature. This still creates savings.

Remember, our homeowners wanted units in the living room and master bedroom because those rooms wouldn’t get hot enough. Before, their options were to let them remain cold.

Or, they could crank up the heat even higher, until those rooms warmed up. When they did that, however, they’d end up overheating other parts of the house. And, they’d pay for more oil to do so.

The NETR Difference

Now, it’s different. When the living room is too cold, the ductless unit kicks on.Then, it turns back off once the room is warm enough. Then it turns back off. The one in the bedroom does the same.

If, say, the living room warms up before the bedroom, that unit turns off first. Now, the homeowners aren’t using more of that expensive oil to keep heating the house just for the bedroom. Instead, that one unit stays on until the room is ready. But, it’s using far less energy to do the job.

Now, our homeowners have even heating in their ranch for the first time. They also have whisper-quiet air conditioning in the summer. And they have lower energy bills. Their home may be a few decades old, but their HVAC system is totally up-to-date.
