What Local Homeowners Are Saying

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

David and his team did a wonderful job installing mini-splits for our entire home. They were punctual, knowledgeable, responsive and highly professional through the entire process of quoting through installation. They seemed to have a deeper understanding of the systems than their competitors delivering a more efficient system at a better value. We’re very happy with our mini-split system!

Working with Paul and his team was excellent start to finish. Very professional and responsive. Got 3 heat pumps and they took care of the $10k mass save rebate too. Love it.

When I discovered that my existing system had failed and was not worth repairing, I thought I was about to enter a nightmare scenario. Fortunately, I have a great relationship with Handyman.com of MetroWest and Cental Mass who strongly recommended SumZero Energy Systems to me. I'm grateful to Handyman.com for the recommendation. SumZero is a great company because of the top-of-the-line equipment they sell and more importantly the great people that are the company. Whether you are talking to Sarai on the phone, meeting with David in person, getting service from the technicians, or admiring the professionalism of the Installation Experts and working directly with your Project Manager you'll realize as I did that it's the people in the company that make it a great company. So, it wasn't a nightmare after all. I'm living "The Dream" with new Cental Air and an additional supplemental Mitsubishi wall mounted Split Unit for the Second Floor. My home is an old house, so it needed a custom installation with expert planning. I could not be any happier. I'm actually kind of happy the old system failed because what I have now is Ten Times better than what I had originally. And the new systems are more affordable than the original. All's well that ends well. Thank you SumZero.
