What Local Homeowners Are Saying

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

We contracted with SumZero Energy Systems for a Heat Pump installation to our 140 year old home. Raphael came to our home and took the time needed to explain the equipment and installation process in full. He worked with us to facilitate the electrical upgrade required for the new system. The electrician worked with our City and electric utility to get us the complicated upgrade despite the equipment supply shortages. The installation coordinator, Jackson came out and walked around the house and discussed the location of vents, returns and mini-splits throughout our home, always listening to our concerns. We also went outside to locate the placement of the exterior equipment, again listening to our concerns. SumZero promised a two day installation for our complicated installation and they delivered. The installation crew was courteous and considerate during the whole process and left our property immaculate. The system was up and running by the end of the second day. In addition, our two old oil furnaces were removed. Our two oil tanks in the basement were also removed professionally with all hazardous waste handled by licensed personnel. The office staff was very helpful in the processing of the Heat Loan (0% financing) and the MassSave Rebate ($10,000). The Heat Loan was approved quickly keeping our installation date on track and the MassSave rebate was approved within 30 days of installation. We have enjoyed the comfort of full home air conditioning during the summer, not missing our AC window units at all. We look forward to heating our home this winter without burning oil.

The first word that comes to mind is OUTSTANDING when I think about SumZero. My husband and I just bought a home with a very old HVAC system and knew we needed an update. The first thing we did was speak with Sarai Ortiz who explained to us all of the steps we needed to take in order to see what system was best for us. She was very helpful and followed up with us throughout the entire process. Hearing that we needed a new system, David Sampaio promptly came to our house to give us a quote on what system he thought was best. My husband loved what he presented and did not hesitate to take the offer. Since we did not have the expenses for the system at hand, Sarai walked us through getting a heat loan through Mass Save. This process was so easy and the loan was finalized within a week! We were so excited to get things rolling, but of course things were on hold due to the pandemic. Even though we had to wait a couple more weeks than anticipated, Sarai and David kept us in the know and answered every question that we had. Once the time came to have the new system, SumZero was more than happy to make us a priority! The workers were on time, efficient, and very kind. Not once did I worry or question the quality of work they were doing. After two days, the work was complete! Daniel was able to walk me through what was installed and how to use the new thermostat, which we love! We now have a home that is comfortable to live in no matter the season. If you’re looking for a new HVAC system, SumZero is the one to call!

Before any home upgrade or repair I do a ton of research, and estimates way beyond the average. As any home owner you try your best not to get taken in any way. After months of research and estimates I found these folks at SumZero. I was more impressed with their motivation to try to get me the best deal, as hassle free as it can be install, and definitely the service after the fact. They went out of their way to help me with the process with MASS Save, and any other discounts I could possibly be entitled to, which for me was the deal maker. Secondly, the products, they gave me a bunch to choose from, all the selections were brand names that we can trust and are high quality. After my estimates I took that information and looked up each one and was very pleased with the options they could do. All top notch pieces of equipment with great reviews. So We decided to give them the job, and boy did we do the right thing. Install took a day, they were very good, and cleaned up the mess before leaving, it was a very large project. No complaints. once the system was installed we immediately seen a difference in our utility bills. What a difference! Lastly, we had 2 small problems in the weeks to come and SumZero came out promptly, and addressed my concerns right away. They even had to replace the air filtration system. wasnt SumZero's fault. Just happen to be the first customer to have a defective one from their company. Within a couple of days they came back and replaced it. During all of this from start to finish, everyone I dealt with was super awesome, friendly, and got the answers i needed in a very quickly and professionally. I am not the type to write reviews very often, but these guys deserve it. They want to be a bigger company, they are highly motivated, and they want you to be happy. Thats becoming pretty rare these days in my opinion. These guys at the very least deserve a chance at your business. Dont be worried about getting plenty of estimates, you will quickly see a pattern, and the have SumZero give you an estimate and you will see what I mean.
