East Boston Multi-Family Home Gets Personalized Comfort with Mitsubishi Ductless System

Boston multi-family home gets three zoned Mitsubishi ductless.

Multi-family homes like this one are common in East Boston. Most were built well before central heat and air were common place and though some have pretty good heating systems, the lack of air conditioning can be a real problem in the summer.

Our homeowners used window units throughout their home, but it wasn’t giving them the comfort they needed in the increasingly hot and humid Boston summers. They gave us a call at N.E.T.R., Inc., to find a better cooling solution that would keep them comfortable without costing an arm and a leg to install or run.


Problem: The family needed additional cooling, since their window AC units just weren’t cutting it, and they were losing sleep because of the heat.

Solution: Three zones of Mitsubishi ductless air conditioning were installed to keep the master bedroom, top floor bedroom, and kitchen comfortable all year long while saving money on energy bills!


Our family knew it was time to replace their window air conditioners because they couldn’t keep up with the heat during the summer. These AC units were also noisy, expensive to run, bulky and heavy, and a pain to put in and store in the winter. Not to mention, these kinds of AC systems block up your window for almost half the year, leaving the house darker and less inviting. There had to be a better way.

When this family called us, we knew right away from our experience in all parts of the Boston area that multi-family homes like this one need a solution that provides personalized comfort, but also works with the house.

Mitsubishi Electric ductless heat pump systems are perfect for homes like this one with no central ductwork. These ductless heating and cooling systems have an outdoor unit that then connects to indoor cassettes which are mounted up on the wall, out of the way. Each unit is controlled independently, which creates a separate zone of comfort in each location. One outdoor unit can service up to 5 indoor units, which makes them often a cost-effect and leaves the option to expand the system later. These multi-zoned heating and cooling systems are very different from traditional whole home air conditioning units in this way.

These Mitsubishi ductless units are designed to monitor both the temperature and the humidity in a room as well as, distribute the cool air evenly throughout the space. This helps to avoid those hot and cold spots you get with a traditional air conditioner alone. Each wall unit is controlled by a remote and can be adjusted independently. You can keep the kitchen cooler when you’re cooking and turn off the unit in the bedroom when not in use, which can save you significant money in energy costs every month.

One of the best features of Mitsubishi ductless heat pumps for the Boston area is that they double as heaters, providing that extra touch of heat you need in a room without cranking up the thermostat in the rest of the house. They work efficiently even when it’s -13F outside, which is great news for these homeowners, since the bedroom on the top floor can get pretty frosty during the winter.

With the new Hyper-Heat system, you can just pick up the remote and adjust the temperature to your needs. In a few minutes you’ll have a cozy space to wake up in!  No more dashing around to get dressed in the morning before rushing down to warmer parts of the house.

Likewise, in the summer, if you wake up at night and it’s a little hot, a simple adjustment with the Mitsubishi Electric remote and you’ll be back to a peaceful night’s sleep in no time.  Best of all, these units are super quiet- we’ve even had people install them in their music rooms where they record, because they are so quiet to run that you can barely hear them!

The real benefit to Mitsubishi ductless is their energy efficiency. The units use inverter technology to use the exact amount of energy they need to maintain consistent comfort- similar to high-end whole home HVAC systems.

In addition, these Mitsubishi Electric ductless systems qualify for rebates from the government because of their high efficiency ratings. Our family, here in East Boston, was able to qualify for a $300 Mass Save rebate to help bring down the cost of installation, with helped to make this an even more affordable, permanent cooling solution for their home.
