The owners of this gorgeous brownstone home in Boston had a problem. They had an existing Sanyo ductless air conditioning system, but it wasn't working properly. The homeowners really liked the ductless system they had, but wanted to upgrade it and make sure all the areas of the home were comfortable. They also wanted to be able to control the temperature at home remotely through a smart phone if possible.

Boston Brownstone gets modern comfort and control with mitsubishi ductless

When the homeowners gave us a call, we went out and took a look at the existing Sanyo system. It was clear that it had serious problems, and needed to be replaced, but we also knew that we could save the homeowners money by designing a system that would save them money on energy costs as well as installation.


Problem: Existing Sanyo ductless system wasn't working, and needed to be replaced. The owners were looking to upgrade the comfort in their home and have the ability to control the system remotely.

Solution: We were able to upgrade their current system with a single Mitsubishi Outdoor condenser and five indoor zones of comfort, along with a Kumo Cloud interface, allowing all the units to be controlled remotely through a smart phone app. This means the homeowners will get the comfort they need and can monitor their home from anywhere, while reaping savings from energy efficiency, a Mass Save Rebate, and ability to control every zone, even when they're not home.

We were also able to install the condenser on the roof, ensuring it was accessible if need be, but also out of the way, so the homeowners could still enjoy the views from their rooftop patio!

The other addition that made a new Mitsubishi's ductless system such a great choice for a Boston brownstone like this one is the ability to add a Kumo Cloud wi-fi interface for the units, so each individual cassette and zone throughout the home can easily be controlled from a smart phone app! This lets you bump up the heat before you get out of bed on a cold, frosty fall day for your bedroom and kitchen, and also turn down the heat after you leave for all the rooms, especially the bedrooms when not in use.
