Somerville Home Gets Mitsubishi Ductless AC for Attic Comfort

Somerville home gets Mitsubishi ductless AC for attic comfort

Homes built in the 1800’s, like this one in Somerville, were built long before central air conditioning. Our homeowners wanted to convert their attic space into a usable space that is as comfortable as the rest of the house.

Attic spaces are notoriously hard to heat and cool. In the summer, the heat from the rest of the house rises to the attic, making it hot and uncomfortable. Then, in the winter, when you might expect the attic to be warm for the same reason, poor insulation and air circulation causes attics to be frigid.

When the homeowner called us looking for a cost-effective, energy-efficient solution for their problem, we knew exactly what they needed.


Problem: The owners of this 1800’s home had no heat or air conditioning for the third-floor attic space, which was always too hot or too cold for comfort.

Solution: N.E.T.R., Inc. added two Mitsubishi ductless HVAC units to the third-floor attic and created a great oasis in the home that everyone can enjoy!


Indoor installation of ductless unit for heating and cooling in SomervilleMitsubishi  ductless split system AC is a great solution for older homes, because it allows you to add zones of heating and air conditioning where you need it most. These split systems solve the problem of hot and cold spots that many homes deal with daily and they do not any ductwork. The ductless heating and cooling system has minimal impact on the beauty and architectural features on these gorgeous older homes, while providing modern comfort during all seasons of the year.

The ductless HVAC system works with an outdoor, heat pump, condenser unit and indoor wall-mounted cassettes. These indoor units distribute air throughout a room quietly and monitor temperature as well as humidity. You can control the temperature with a hand held remote or you add a wall thermostat. There are even cloud-enabled apps that can be installed as add-ons to make control of the system as easy, even when you are not home! Once you set your comfort level, the units use an inverter technology to keep the temperature steady, using as little energy as possible.

Ductless Savings

Our homeowners opted for two indoor Mitsubishi Electric ductless units to keep the rooms in attic space comfortable. Choosing such an energy-efficient option, added comfort to their home that will save them money on energy bills all year long. When compared to the noisy window AC units they had been relying on in the past, this solution is so energy-efficient, the homeowners qualified for energy-saving rebates. Through the Mass Save program they qualified for a rebate of $200 and a Mass CEC rebate of $1,302, bringing a total savings of $1,502! Those savings helped this upgrade in long term, heating and cooling comfort to be even more affordable.

Mitsubishi ductless systems are great because they work both as heating and cooling systems through one unit. This means the homeowners can have that touch of warmth they want on the third floor during the winter, without having to crank up the heat for the whole house. Likewise, during the summer, they can add the perfect chill to the air when they need it and keep the whole third-floor cool.

The whisper-quiet operation will make this third-floor space one of the most popular in the house, with its custom, adjustable heating and cooling ability. The units can even be turned off if the space isn’t in use, so the homeowners can avoid wasting money on energy bills!

In the end, N.E.T.R., Inc. was able to deliver an efficient and cost-effective solution to make this Somerville attic one of the best spaces in the home. If you have a space in your home that is never the right temperature, give us a call here at N.E.T.R., Inc. and we’ll find a comfort solution that’s right for you.
