Boiler Installation Services

My wife and I bought a house that had oil heating baseboards and windows AC. We called a few companies to get a quote to replace to central air, but once we talk to SumZero the choice was clear. IIija was very professional and friendly. He explained the entire system and process to us as clear as it gets. He guided us to a system that would accommodate all of our needs. From that moment on I have to say the customer service was beyond expectations. His team was very professional and did an amazing job. They explained me how everything works. We couldn’t asked for more. Definitely would recommend anyone who wants great service call SumZero. They know how to treat a customer. Thanks IIija and the entire SumZero team.

They are the best to work with. I had my furnace replaced along with 2 new heat pumps for the 2 floors. Everyone involved, right from Raphael who came to give me solutions and estimates to the people who actually did the work were super helpful and detail oriented. They completed the project in time and cleaned the place well post visit. Dan and Roman came the day after install to fine tune the system and were super helpful. They also promptly replaced the thermostat that was incorrectly installed. How the system really performs is yet to be seen in the summer and peak winters. But, the overall experience with the team was absolutely great.

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!
