Central AC Installation

... 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

I recently purchased a new home that is heated and cooled using 6 mini splits throughout the house — I was a bit anxious about these units providing sufficient AC or heat—This summer was very hot and humid and the units worked great — I had SumZero come out today to check all of my units and to reassure me that they are all in great working order for the upcoming winter — I met with Daniel and immediately felt comfortable with his knowledge and skill set with mini splits —He was very professional and addressed all my concerns before he inspected each unit — He was patient and spent over an hour testing each unit and keeping me posted as to his findings—Thank goodness they are all in great working order and my anxiety about these mini splits was put to ease — I had another company come out a few months back—They were very professional but admitted mini splits were not their specialty—Dan was very confident and detailed in educating me and evaluating my mini splits — IF YOU NEED SOME HELP OR MAINTENANCE WITH THIS TYPE OF HEATING/AC units, CALL SumZero ! You will be so glad you did Ken

If we could give SumZero Energy 6 stars, we would! We found them via an email outreach they did, and from the very first contact all the way through final installation and tech check, we can't rave enough about this company. Raphael, our sales rep, was excellent with superb communication and follow-up. Likewise, Paulo and his installation crew were polite. knowledgeable, hard-working, and a pleasure to deal with. Even the staff at the main office has excellent communications skills and follow through. Top to bottom, SumZero works extra hard to meet your needs and make you happy. They even guided us to make sure we got the maximum rebates allowed. We chose a Mitsubishi heat pump system and are very happy with it so far. It's a big technology leap for us but we are confident that the SumZero team will make sure that our first winter/summer seasons go smoothly. Do not hesitate to hire this company!
