There are lots of two-family dwellings in and around Boston, like this home in Middleton, MA. We were called out to inspect the home for heating and air conditioning problems earlier in the summer of 2016.

With one family on the upper level and the other on the lower level of the home, a poorly designed, inefficient baseboard heating and central air conditioning system produced very different levels of temperature and comfort. This set-up left both families uncomfortable and unhappy.

That was why these homeowners in Middleton called N.E.T.R. Inc..

The family on the upper level needed a heating and cooling solution that enabled them to be comfortable -- the upper level ended up being too cold in winter and too hot in the summer, never achieving the comfort they craved. They needed an air conditioning solution to cool their entire living space and end the hot and cold spots throughout their space.

Problem: The family occupying the upper level of this two-family home was too hot in the summer and too cold in the winter. The oil boiler and baseboard heat often left the furthest parts of the upstairs chilly and damp. For these reasons, it was important that the solution not result in unintended discomfort for the downstairs occupants.

Solution: We installed a pair of Mitsubishi Electric Hyper-Heating H2i indoor units powered by one outdoor unit. This is called a multi-zone ductless mini split system provides whisper-quiet air conditioning wherever it’s needed. This eliminated their dependence on home heating oil and reduced their overall monthly energy costs.

Heating your home using oil is a common practice. You fill up, and you get your oil refilled when needed. With the price of oil always fluctuating, what can you do to try to maintain a budget? And what about getting some air conditioning in these hot and sticky summers?

Our Boxford homeowners were having just this problem. They were heating their home with oil and baseboard heating units throughout the house, but rooms would take a long time to heat up or cool down. In addition, because the house didn't have any ductwork, the homeowners had to rely on window air conditioning units to try to get some relief in the summer months (and longer into the fall as well!) They suspected there was a better way to heat and cool their home that might also take the bite out of the oil bills that always seem to come at the worst time. 

The Ideal Heating and Air Conditioning System for a Boxford, MA Home

The experts here at N.E.T.R. INC. went out to check out the home and realized that they could create multiple zones of comfort that could deliver both heating and cooling on demand for our homeowners! The family wanted to make sure their kitchen and pool room remained comfortable, as well as their master bedroom and the kid's bedroom as well. Since they spend most of their days downstairs, making sure they had the main gathering area in any house- the kitchen- comfy was important. Just as important was to make sure the bedrooms were just the right temperature so that everyone got a restful night’s sleep all year 'round.

Like many busy families, our homeowners want to be able to get the most out of their home, but don't want to dread going to bed because the upstairs is just too hot or too cold. Our experts were able to design a mini split heating and air conditioning system that used a single outdoor heat pump but could power four separate indoor wall mounted AC units, like the one on the left. This allowed a zone by zone customization of temperature and comfort as needed! This switch from oil heat to electric heating and cooling will help to keep the energy bill lower, and more predictable, even during the summer- something every growing family needs.

Problem: The existing oil heating system was alright, but the homeowner wanted lower energy bills, and increased comfort in the summer.

Solution: An electric Mitsubishi Hyper-Heating heat pump system will allow efficient heating AND cooling, on demand, any day of the year. In addition, the ductless system has built-in fans to help circulate the air and ensure even distribution of hot or cool air throughout a room, increasing comfort throughout!

Many times, you can make your existing home more functional by putting on an addition or renovating unused space in an attic or basement. These additions were never factored into the design of your current heating and air conditioning systems, but they certainly need the comfort you expect in the rest of your home! This situation presented a perfect opportunity for a ductless mini-split installation in this Reading, MA, sunroom.

Our homeowners in Reading, MA, added a gorgeous addition. These rooms are often called three-season rooms -- because they are far too cold in the winter to be used all year round. The family wanted a heating and cooling solution for their addition that would let them use the room all year long. After all, why add a sunroom if you can only use it part of the year? When they came to us, we knew that a Mitsubishi ductless Hyper-Heating system would be the perfect solution to provide the comfort they needed every day.

Installing a Mitsubishi Hyper-Heating ductless heat pump creates a separate zone of heating and cooling for the addition. Temperature can be adjusted easily by remote control, and the unit will provide pinpoint, quiet heating or air conditioning at the touch of a button. This system is reliable, even when the temperature is -13 degrees! The unit is installed up on the wall, out of the way, and will distribute the cooled or heated air throughout the space, ensuring comfort no matter what Mother Nature has in store.

Our homeowners wanted their new three-season room to be comfortable all the time- not just "in season." They needed an efficient heat pump system that wouldn't run up their energy bills. They were looking for a high quality, reliable system that would last years.

The choice of a Mitsubishi ductless Hyper-Heating unit was an obvious solution for this addition. Instead of adding additional stress to their existing HVAC system to heat and cool this addition, an independent zone of heating and cooling is a much better choice.  Sunrooms have many windows and provide an indoor place to enjoy the sunlight- but this also means that they can get pretty uncomfortable in the dead of winter or the summer heat.

Fortunately, the incredibly efficient, quiet heating and cooling provided by Mitsubishi ductless will give the ideal heat and air at the touch of a button. This control is allowing the homeowners to adjust the temperature to achieve perfection any day of the year.  Now, the money and effort in creating this new space in their home can be enjoyed all year.  The owners get four-season comfort, and they can enjoy their new space, regardless of what Mother Nature decides to dish out.

The efficiency of ductless heating brings maximum heat without traditional fossil fuel systems. Many of our customers rave about the money they save on heating bills once they get a ductless HVAC system installed. Especially in hard to heat rooms like a three-season room, Mitsubishi ductless will be able to deliver the heat needed at lower operating costs than any comparable solution- and it will provide cooling in the summer as well, something you don't get with other options like wood stoves or space heaters.

The key points of this home:

• The homeowners now have a comfortable, quiet solution to heat and cool the new three-season room addition- we now call it their four-season room!

• No removal or replacement of equipment was necessary, and the new ductless equipment is installed out of the way. The system will provide heating and cooling for this room, making it one of the most comfortable rooms in the house, and day of the year.

• The new system is efficient and will make sure that the new addition doesn't add whopping new energy bills along with it!

A Great Investment

Our homeowners will still be using their traditional HVAC system to heat and cool their home. This addition will have its own separate zone allowing it to be adjusted independently of the rest of the house. That means the homeowners will use the system only when they need it, minimizing any additional costs to heat and cool this beautiful new space.  They will get pinpoint control over the temperature in the room, keeping it comfortable - maybe even more so than other areas of the house!  This installation will also provide air conditioning, making spring and summer much more comfortable as well- and ensure the owners get maximum enjoyment out of their investment.

This attractive home in Roslindale, MA, had a problem that many homes have- the home office was too hot in summer and too cold in winter. The homeowner was trying to make do in the winter with a space heater, but it wasn't working. The space heater couldn't keep the office sufficiently warm, and it was expensive to run. There had to be a better option available. When the homeowner called N.E.T.R., Inc., we evaluated their issue and knew a Mitsubishi Hyper-Heating ductless system would be a perfect fit.

The Ideal Air Conditioning and Heating Solution for a Massachusetts Home

Many more people are working from home these days, whether it's telecommuting a few days a week, or getting a bit more done after hours and on weekends. The home office is now an integral part of most homes, and it's important to have the level of comfort you need to be productive.

Our experience with homes like this one in Roslindale is unparalleled in the Boston area. In order the achieve adequate cooling in the summer, window air conditioners don't seem to cut it anymore. These units are noisy, and they're power-hungry, really running up the energy bills! Likewise, space heaters tend to warm only part of a room but fail to keep a space like an office adequately warm during the winter, plus they're expensive to run

The solution to enhance our homeowner's at-home productivity while lowering their energy bills was clear. They needed to create a new heating and cooling zone for the area they were spending the most time in- the home office. 

After a review, we recommended adding a new heating and cooling zone with Mitsubishi Hyper-Heating. Not only does ductless work well down to temperatures below -13 degrees to deliver heat on demand, but it also functions as an efficient air conditioner.

By adding this ductless zone, our homeowners can maximize comfort in the office without having to adjust the thermostat for the whole house. This Mitsubishi ductless system will save them money by just heating and cooling the area where it's most needed, on demand. No removal or changes to their existing HVAC system was required.

Woburn has a number of cape style homes like this one-great homes that often were built when the heating and cooling needs were much different than they are today. Our homeowners were using a pellet stove to heat their home, but they were finding that it was very dirty and required a lot of cleaning and maintenance that was getting to be a nuisance. They were looking for a solution that would provide them with greater comfort year-round, while also enhancing the charm of their home.

A Ductless HVAC Solution for This Classic Cape-style Woburn Home

We were able to install a ductless heating and cooling unit to act as a supplement to the current pellet stove. The ductless unit can be relied on for heating and cooling at the touch of a button, winter or summer. The Mitsubishi Hyper Heat pump units provide efficient heat in the winter but can also provide cooling in the summer. In addition, these units are ductless, so all you see is the wall mounted HVAC unit tucked up out of the way near the ceiling.

We did not have to remove the pellet stove but left it in place in case the owners do want to use it during winter for additional heat. By leaving the old equipment in place, we were able to save time and money while disturbing as little as possible in the home itself, making this a high impact, low profile upgrade to the home.

The Mitsubishi Hyper Heat units are operated by a simple remote control, allowing pinpoint adjustments to both heating and cooling at the touch of a button. Now instead of having hot & cold spots in this picture-perfect home, the homeowners will enjoy the comfort you might expect in such a lovely and picturesque surrounding.

A lot of older homes in our area have baseboard radiators with an oil burner, like this homeowner in Wilmington, MA. While hydronic heat is a great heating solution, it doesn't do anything to help cool the house.

And, if you don't have ductwork for central air conditioning, you are stuck with finding another option to keep cool in the increasingly warm and humid New England summers. Most people use window air conditioners, but these often don't do a great job of cooling more than one room at a time.

If you have an open floor plan with a combined kitchen and family room, like our homeowners, getting the whole area comfortable can be a real challenge!

Window air conditioning units just can't circulate the air through a big living space well, and they are noisy, which can really reduce your enjoyment of such a great open space. Plus, without adequate cooling, wooden chairs and handrails start to feel sticky, just from the buildup of humidity. That's no way to spend your summer.

In the winter, the baseboard heating system takes a long time to heat up a room adequately and does not circulate heat well, leading to hot and cold spots - especially in an open floor plan - which can be very frustrating. 

Based on our homeowner's need to get adequate heating and cooling to all the rooms on the main floor, including a combined kitchen and family room, and one bedroom, the experts at N.E.T.R. INC. knew that a Mitsubishi ductless system would be the perfect solution. The wall-mounted units can circulate air well through a larger area, and they are whisper-quiet! No ductwork must be installed, and the remote control allows pinpoint adjustment in temperature to ensure perfect comfort for your family.

In addition, the Mitsubishi Hyper-Heating heat pump works to provide air conditioning in the summer, but can provide supplemental heating in the winter as well. These energy efficient systems are great in helping homeowners achieve increased comfort right where they need it most, while saving money on traditional energy bills.

These highly efficient systems are also eligible for rebates from the Mass Save program because they are environmentally friendly, and this family qualified for a $250 Cool Smart rebate as a result!  

Our homeowners greatly increased the comfort in their open floor plan home in ways they couldn't accomplish through traditional methods, and without the pain of dealing with window air conditioners or installing ductwork.

Problem: This home in Wilmington had an open floor plan and baseboard heat that made it hard to stay warm in the winter and hard to cool in the summer. Oil heat can be expensive, and the homeowners were trying to rely on seasonal installation of window air conditioners that were inadequate.

Solution:  Installing a Mitsubishi Hyper-Heating system designed to provide flawless heating in the winter and world-class air conditioning in summer results in both dramatically lower energy bills and increased comfort throughout the entire first floor in this home. 

Most of New England, is filled with older homes, like this one in Allston. And while these homes are full of great architectural features, most were built during a time when air conditioning was a luxury reserved for the well-to-do. Heating and cooling older homes can be expensive, especially when you try to achieve balanced temperatures throughout the house. One room may be too cold while another is too hot, resulting in a never-ending battle for control of the thermostat. The only way to make those cold rooms comfortable is to crank up the heat, which overheats the warm rooms and costs the owners on their energy bills. This was the situation we were brought in to solve for this family in Allston, MA.

Problem: The family wanted to save money on heating and cooling.  They were looking for a multi-zoned system so they could heat and cool areas as needed, rather than waste money heating empty space.

Solution: Installed a Mitsubishi Hyper-Heating ductless inverter with five zones of comfort in the bedrooms and main living area. We put in five wall AC units, creating zones of comfort throughout this classic home.

Marlborough is as picturesque as New England towns get, a mix of historic elements and the natural beauty everywhere. It's a great place to live, but if there are areas of your home that just aren't comfortable, they will be under-utilized and end up just being wasted space.

Our homeowners had a third-floor bedroom in their home, and like most rooms on the top floor of a house, it was way too hot in the summer and almost too cold in the winter.

 
Problem: The third-floor bedroom was uncomfortable most of the year -- too hot in summer and way too cold in winter, despite the skylights! The homeowners needed a way to make this space comfortable and usable for their family. 

Solution: A simple Mitsubishi ductless heating and cooling unit will bring added comfort to the third floor, making it a place everyone will want to be, any time of the year.

The Ideal Heating and Air Conditioning System for an Attic or Third-Floor Bedroom

While the rest of this modern home had adequate heating and cooling, and wonderful casement windows, this wasn't working well for the third floor. Even with central air, a third floor/attic room will always be a challenge to heat or cool. Window air conditioner units don't work with casement windows or skylights, that's for sure, and the baseboard heaters just weren't providing enough heat to keep the space comfortable.

Our experts at NETR knew that a simple single-unit ductless HVAC system from Mitsubishi could solve this problem once and for all and make the third floor one of the most comfortable spaces in the home! The energy efficient technology is able to both heat and cool on demand and do so without adding significantly to the energy bills for the rest of the home.  In fact, since the existing system will have to work less hard by not needing to heat or cool the third floor, we wouldn't be surprised if the owner's overall energy bills go down over time!

Boston is home to world class universities on the cutting edge of technology. So, it was no surprise when our homeowner in Boston's North End wanted to make sure he could control his heating and cooling system remotely, by an app on his smartphone. The homeowner has an older, forced air heat pump system that was due to be replaced. He wanted to upgrade to a solution that offered maximum comfort along with the convenience of remote operation.

Problem: The existing forced air heat pump system needed replacement and the homeowner wanted the new system to maximize comfort and convenience and allowed him to control the system remotely from a smart phone.

Solution: A four-zone Mitsubishi ductless split system powered by one outdoor condenser and four wall-mounted heads maximized comfort while a Kumo Cloud controller allowed remote operation from anywhere from a smartphone or computer.

Living in an older home doesn't forego modern solutions to comfort!

We were able to upgrade the old heat pump with Mitsubishi's Hyper-Heating ductless mini split system, which is proven to remain effective in the temperatures as low as -13F degrees, and it provides world-class, quiet, cooling in the hot and humid summers. We installed four wall mounted units to ensure comfort throughout the home, with only one outdoor heat pump needed, which was mounted on the roof so it was secure and out of the way.

It was a priority to our homeowner that he could control the units remotely, as many newer systems allow. By installing the Kumo Cloud controllers for the Mitsubishi systems the homeowner can now control the climate in his home no matter where they are on the planet! If he forgot to adjust the thermostat before leaving for a weekend on the Cape? No problem- just bring up the app and the Kumo controllers will adjust the temperature from anywhere. Need a little extra comfort on a really hot day for your dog or cat? It’s easy to monitor how warm or cold your home is from the app and adjust it as needed when Mother Nature serves up a surprise hot or cold snap. Likewise, they can adjust the temperature before they get home from work, making sure they always come home to a comfortable home, without spending extra money to heat or cool spaces when they aren't there.

We can Install Units Almost Anywhere!

There's nothing better that the excitement of adding a new space in your home. But often, bonus rooms, three season porches, and rooms over a garage, like the one our homeowners were adding, can be heating and cooling nightmares. When you add additional living space over a garage, you get additional square footage, but because the space below is largely empty and often not well insulated, the room above tends to be extra steamy in the summer and pretty chilly in the winter.

What's the best way to solve a problem like this? Our Wilmington, MA homeowners contacted us, and we knew a simple single zone Mitsubishi Hyper Heat system would do the trick. Adding a single zone of ductless HVAC can be just the thing for those difficult to heat and cool rooms in your home. Unlike options like electric baseboard, ductless units work as heating and air conditioning, all at the touch of a button on a remote control. Plus, with the built-in sensors and fans to distribute the air around the room, you get even distribution of hot or cold air throughout a room, ensuring perfect comfort. Mitsubishi Hyper Heat systems are also super-efficient, so it will save you money on energy costs, and it will allow you to heat or cool this room by itself, without worrying about the temperature for the rest of your home.
