What Local Homeowners Are Saying

See how SumZero has helped local homeowners stay comfortable year-round with energy-efficient heat pump solutions.

I strongly recommend SumZero Energy Systems for your mini-split project. I had a great end to end experience with them and would use them again. Of my three quotes SumZero was not the cheapest but it was the best value for money. I have a tricky layout and SumZero proposed ceiling cassettes for the tricky parts and were the only company that were confident in being able to do the job with ceiling cassettes. They did a Manual J and they came up with a good solution. They helped me with the loan and rebate process. They were always responsive. The install team in particular were spectacular. They showed up on time, did the work efficiently, neatly and cleanly. Their planning and execution were superb. Even the hidden parts of the job in the attic were super neat. They restored the attic insulation to pristine condition. They implemented a solution where you can only see one line set channel outside the house, going straight up from the condenser. You would not know that this serves four heads inside the house.

We hired SumZero to install a ductless mini split system and it was a great overall experience, David Sampaio helped quote and spec out the install and was great at coordinating the project. The team who installed everything completed the job in only a few hours: they were professional, fast, and cleaned up well. They even went above and beyond to help me check something unrelated to the install on the outside of my house. Very easy company to work with and we're very pleased with their work so far.

UPDATE: It's been about 3 months since my new heat pump and gas furnace were installed and things have been humming along, moving seamlessly from cooling to heating. When the temps dropped close to 20 a couple of weeks ago though, the heat pump began to work a little harder and longer at squeezing heat from the frigid air (as we knew it would). So I looked to boost the BTU's by firing up the furnace. Though the blower came on, there was no gas, no flame. A check of the gas line valve and the circuit breaker all looked good. Working different modes on the thermostat I tried multiple times, but the furnace remained cold. I gave SumZero customer support a call first thing Monday morning and got voicemail. Though the message proclaimed my "call was important," my heart sank a little wondering WHEN I would hear back. But Lara cheerfully got back to me within the hour and said she would have a technician by the name of Dan Jameson out to the house between 1:00 and 3:00. Dan arrived a little before 2:30 with the same sunny disposition that seems to be part of the culture at SumZero. He invited me to shadow him and learn a little bit more about my HVAC system while he checked it out. He quickly discovered that an internal gas valve was in the off position, something town inspectors like to see when heating is not required (though it really isn't necessary). Needless to say, the furnace began working like a champ. Dan also took time to check the filter, the heat pump, and program the thermostat, all the while answering my questions and giving me valuable pointers as well. Now when the weather drops below freezing, the heating automatically kicks over to the gas furnace. Should any other questions come up, Dan made a point of saying to be sure to call and, if need be, they'd be happy to come out to the house to explain. Once again, everything is working as it should. And SumZero rocks! Though you try to get some idea of who you are hiring through online reviews and asking the right questions (if you even know what questions to ask), a lot of blind trust goes into choosing a contractor - trust that you'll get what was agreed to, on time, in working order, and at the right price. I'm happy to say that SumZero checks all the boxes - and then some. From sales rep Paul Jameson to Sarai and Lara in the office, to Wanderson and his installation team led by Paulo, ALL were professional, knowledgeable, super polite, and patient - exemplars of what customer service used to be. I am very, very happy with my whole house heat pump and additional duct work that was extended into a recent addition. An added bonus is that they will help with the submission of paperwork for the Mass Save rebate. For family and friends contemplating similar work in their homes, I'll definitely point them SumZero's way. Well done!
