Mini-Split-Mixed-Applications

... 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

Great company! Honest people and fair prices. If you're anything like me, you hate shoddy work, and in the home remodeling industry, there's a lot of that. I would rather pay a premium to ensure it is done right and the quality is there. SumZero does that and more. We called, and within a day, they sent one of their experts, Raphael G., to quote us for ductless mini-splits to outfit our home. He was very thorough, offering different options that would work for our living room and bedrooms, which are boiling and humid during the summertime. He made the process extremely easy for us to understand and was willing to work directly with our condo association to accommodate their requests. We're still waiting to get them approved by our condo association, as there is a lot of work involved in obtaining approval. However, so far, the experience has been nothing but easy and painless. I'm looking forward to having the mini-splits installed.

The entire team from Sum Zero Energy was excellent. From the initial contact and estimate to the installment and cleanup. They were also helpful with loan details. The electricians were very knowledgeable and explained everything to me. The crew that installed the mini splits on the outside and inside of the house were efficient and knowledgable. Once the job was completed, they explained how everything worked, cleaned up and disposed of everything. We were very pleased with the work and the entire experience with the company.
