Our Process

I just had a team from SumZero install an air source heat pump and a new furnace, and I would absolutely do it again. Arthur, Douglass, and Paulo were polite, knowledgeable, and efficient and got all of the work done in a single day. I was stuck in and out of meetings most of the day and they got done what they needed to, explained what they were doing, and were minimally disruptive while here. I’d definitely use these guys again if I needed work done in the future!

... watching contractors work on your house did you ever think- "wow these folks sure work like they work on their own homes?".... No? Sarcastic much? Wishful thinking? I thought so too. We all dread dealing with contractors as we know most of them are.... Dreadful to deal with. Facts. So that is how I felt too when I decided to switch my house from oil heat to electric. Due to the size of the house It was going to be a large project involving a complex setup of multiple condensers, air handlers and ceiling cassettes. I had in mind what I wanted, so I needed a contractor to look at my design and make changes as needed, provide input based on experience and execute it. The vendor would need to understand modern cold weather heat pump solutions and installations in a complex near- commercial environment. They also would need to understand integration with the heavily automated existing controls in my house. Like a good citizen I solicited several well- established HVAC vendors to provide me with quotes. I actually spent an hour or more with each one showing and explaining my property and current set up. All nine of the contractors said they can do it and will provide quotes. I got back... 3 quotes. But it wasn't a problem as I knew which vendor I will go with based on my interactions with them price notwithstanding. Ilija from Sumzero was the only guy that was technical enough and had sufficient knowledge to understand what the project involved and to make welcome changes to the specs and equipment based on load calculations. The installation went as planned. The team led by Paul showed up on time every day and worked extra hours to finish the job in a week. Remember the opening statement about contractors working like they work on their own home... This was how it looked and felt when I watched them work. No corners were cut and when I asked for a bit more here and there I was accommodated without any questions. Marcelo (lead tech) and the team worked hard and provided outstanding results. The last day presented a challenge where my existing controls needed to be integrated with the new controls. Daniel is their controls guy and our initial conversation was actually funny. I started to explain how I want the integration to work and Daniel interrupted me midway and finished my thoughts. Yeah- he is that good. Overall, I believe that companies like Sumzero are very very rare in the field. Knowledge, expertise, work ethics, communications with customer- it is all done well. So if you have an HVAC project regardless of its complexity- you should give them a call. You will not be disappointed. My 2 cents

This was our first annual maintenance service for our heat pumps. Dan was extremely helpful and patient with our requests and questions. Our experience with SumZero has been that they more than just technicians but educators. We highly appreciate Dan’s service.
