In general, the top floor of a home is the hardest to get right in terms of temperature. That problem gets even worse the higher you go. Where most homes are two stories, a house with three stories finds its top floor even harder to maintain. That’s where our techs came in.
Problem: The third-floor living room in a multi-home home in Everett, MA wasn't being heated and cooled efficiently with electric heat and a window air conditioner
Solution: Installed a Mitsubishi ductless HVAC system with an outdoor unit.
Terror on the top floor
Ok, maybe terror is too strong a word. But, challenging is certainly appropriate when it comes to heating and cooling in this Everett, MA home.
The owner of this multi-family home wasn’t happy with his HVAC system on the third floor. This isn’t all that unusual. Getting the top floor of any home is tricky when it comes to climate control. A third floor is even tougher.
Many times, this happens because of where the thermostat is located. Often, there’s one thermostat governing the whole house. And, it’s usually on the first floor.
When that thermostat reaches the temperature you set, it turns off the furnace or central air. But, it’s not taking into account the second floor. Therefore, it’s turning off the unit before the other areas in the house are set.
This is why the upstairs is usually too cold in the winter. In the summer, a top floor ends up too hot. This is for the same reason along with the simple fact that heat rises.
For this home, those problems were even more pronounced. This was for a few reasons. First was the fact that this is a three-story home. Now, there are two extra floors of heat rising to the top, as opposed to just one in a two-story home. That makes it even hotter in the summer.
In the winter, the problem is a little different. This is due to it being a multi-family home. Each unit has different heating needs. It’s difficult, then, to get it right for all three. As a result, the top floor has it the worst.
Third floor’s the charm with ductless HVAC
For a long time, our homeowner was using electric heat and a window air conditioner n the third floor. These helped keep the living room up there warm in the winter and cool in the summer. But, it wasn’t quite cutting it.
He knew he was spending too much money to not get the results he wanted. And, the air conditioner was especially a problem. Not only was it not passing muster, it was way too loud.
It was time for a change. That desire brought him to NETR. The owner knew all about our excellent service and stellar reviews. And, we lived up to reputation.
It was clear early on that a ductless HVAC system was the way to go for this home. It would provide him the flexibility, efficiency and quiet performance he wanted.
Ductless systems work on the same basic principle as older HVAC systems. But, they do so much more efficiently and with less hassle. Here’s how:
A ductless system uses an outdoor unit connected to indoor units through small, flexible tubing. This is much less equipment than a furnace, air conditioner condenser, ductwork and vents. In this case, smaller is definitely better.
That takes us to the third floor. To remedy the situation in the living room, it just took one unit up there. Our techs installed a Mitsubishi wall-mounted unit up near the ceiling. Behind it is a small tube, no wider than an inch. It’s going through the wall, but you can’t even see it thanks to the actual unit.
That tubing travels down the house to an outdoor electric unit that delivers cold or hot air. And, that’s it.
The homeowner didn’t have to spend hundreds and hundreds more for a new ductwork scheme and to have new vents carved out in the walls. And, our techs didn’t have to disrupt the other families living there by building ductwork from the furnace in the basement to the top floor.
Mitsubishi ductless means more comfort for less money
Comfort is a big reason why a Mitsubishi ductless HVAC system is a great unit. But, it’s not the only one. A system such as this is a great long-term investment, and Mitsubishi is a top-of-the-line choice.
Mitsubishi is especially known for quiet, efficient units. That makes them more enjoyable and less costly than others.
Let’s take a look at the ductless air conditioning for instance. Now, the top-floor tenant doesn’t have to deal with a clunky window-unit a/c bocking the light and making all sorts of noise. This is especially notable in a small living area, where that noise can overpower a TV or conversation.
And, with ductless heating, the top floor can truly control its own heat. That makes it a more desirable apartment than before.
For the homeowner, who’s paying the utility bills, it’s less of a burden each month. Mitsubishi ductless systems are proven to be energy efficient. That means they use less energy than other systems to deliver. Less energy means less money you pay for the same effect.
In fact, these systems are so efficient that they can actually earn some money for the people who buy them. Rebates are available from more than one group in Massachusetts for installing energy-effcient HVAC systems. Our salesman made sure this homeowner knew all about them.
In this case, the homeowner got a $625 rebate from the Massachusetts Clean Energy Center. This is a group advocates for clean energy across the state. They also provide incentives for more people to adopt systems like the Mitsubishi one here.
And, he received another $100 from Mass Save. A group of utility company in this organization have a similar mission.
All in all, this homeowner got himself a heating and a/c system that makes the top floor more comfortable, saves him money each month and even put some cash in his hand. That’s three great improvements for his three-story home.

Mitsubishi Ductless Heating
With zoned heating, each unit turns on and off as needed. Let’s say you set the whole house to 66 degrees. A unit a part in a cold part of the house runs until it reaches that temperature. But, a unit where it stays warm will turn off sooner, when that area reached 66 degrees.
Right away, our homeowners started saving money on their monthly heating bills. They left the units in the spare room and office very low or completely off most of the time. The rest of the house stayed nice and warm, however.
In the case of this home, it was very simple to run the tube from the outdoor condenser into room and up the wall. We installed the unit itself over a few of the windows. That way, it works from a spot where you can barely notice it.
The same goes for keeping it cool in the summertime. And, as an added bonus, the unit comes with a remote. Even though it’s high up on the wall, our homeowner can adjust the temperature from anywhere in the room.

The solution here was a
You can also choose to not heat or cool a section of the house all the time. All you have to do is turn off that zone, or set the thermostat accordingly. That’s what this couple planned to do with the second bedroom.

Mitsubishi Ductless HVAC Units to Supplement Oil Heat
Stoughton, MA has many neighborhoods like this one, full of Cape-style homes that were built without central air conditioning. As a result, homeowners rely on window air conditioners to try to keep cool in our increasingly hot and humid summers, and many times, the window units just can't keep up the way a ductless HVAC installation can. The window units are a pain to install and store each year, they are bulky and noisy, and worst of all, they are incredibly energy inefficient, which means ridiculously high energy bills when the hot weather hits. This young family in Stoughton, MA wanted a better solution to provide them the comfort they craved, but without sky high bills that can put an unexpected crimp in anyone's budget.

Wenham, MA has a lot of great homes, and this small Cape style home looks like it could be on a postcard for the Chamber of Commerce! Cape style homes like this one are compact, but they often don't have central air conditioning, and are forced to rely on window air conditioners in the summer.
For these homeowners, a single indoor units would solve their most pressing need- making sure their living room was comfortable. They were tired of trying to watch TV over the noisy window air conditioner, which never seemed to deliver the comfort they wanted. By adding a single zone of ductless to the living room, the homeowners will now be able to spend time in quiet comfort- Mitsubishi ductless units run at only 22db- whisper quiet!
These units are also incredibly energy efficient. They use inverter technology to help maximize their performance while using the smallest amount of energy possible to deliver you the comfort you want. This means that they can really save you money on energy bills, especially when compared to traditional window air conditioners. They are so energy efficient, they also qualify for rebates through the Mass Save program, and these homeowners qualified for $100 rebate, helping to defray some of the cost of this significant upgrade to their home comfort!

Salem, MA is located on the North Shore, and is probably best known for the famous Witch Trials, but it is truly one of the nicest areas around. Being close to the Shore, you will find a lot of Cape-style homes like this one around. While Cape style homes are naturally compact, they can often be surprisingly difficult to heat and cool. The steep roof and gables can make the second floor surprisingly hot in the summer and cool in the Winter. Many of these homes are built without ductwork, so they rely on forced hot water radiators for heat, and end up relying on window air conditioners in the increasingly hot and humid summers.
Mitsubishi Ductless systems are just that- heating and cooling systems that don't rely on ductwork, but instead consist on an outdoor unit and then an expandable number of indoor units that can deliver the comfort you want, right where it's needed most. Each indoor unit can be controlled separately, creating a zone of comfort that can be adjusted as needed, for just those areas of your home in use.
We then added additional units to the living room and office, and then the second floor master bedroom and kid's bedroom.
At N.E.T.R., Inc., we always want to make sure our homeowners get the comfort they want, and it comes with the minimal amount of piping and disruption possible. As you can see from the photographs, we take every opportunity to make sure the lines needed are hidden so the units look like they have no lines running to them- giving each room a finished look that's important when you're renovating and upgrading your home.
What homeowners like this one appreciate the most is that this solution is energy-efficient and cost-effective to run. Anyone who has had any experience with window air conditioners knows how high your energy bills can get during hot weather! Not only that, the window units are hard to install and insulate properly, so you always risk letting bugs in the house, or feeling like you are also cooling the great outdoors. With ductless, you get a permanent solution that has very little maintenance required, unlike the storage and concerns about mold and mildew you can get with window air conditioners.
This energy-efficiency is due to Mitsubishi's inverter technology, that allows the units to use just the right amount of energy to deliver the comfort you want and maintain that comfort level- there are no more wild swings in temperature as a unit kicks on or off. That means that many of our customers see as much as a 40% drop in their energy bills after getting ductless. in fact, the units are so energy efficient, they qualify for both Mass Save and Mass CEC rebates! This family was able to qualify for $500 from the Mass Save program and $2,500 from Mass CEC, saving $3,000 on this significant upgrade in comfort to their home- that's great news for any family's budget!
Best of all, Mitsubishi ductless units work as both heaters and air conditioners, which makes them a real comfort upgrade. As heat pumps, they can add heating or air conditioning on demand, which can allow them to add just that touch of heat you need sometimes, without cranking up the main heating system for the whole home. For those frosty fall mornings or chilly, rainy spring days, all the family will need to do is adjust the level on the handheld remote, and they'll be comfortable in minutes- without having to adjust the comfort level for everyone and every room in the house at the same time.
