I live in a rather bigger home than is normally out there so I knew I was going to be paying much more for a complete hvac replacement.This was going to be a big expenditure on my part so I did a ton of research. So I was looking for a company that would sized the hvac units properly , figure out all the install issues beforehand as best as one could reasonably expect, work with any of my concerns/issues I brought up and in business like, professional, honest and timely manner. Boris and Kam did all that and more. From the initial prompt 2 hour long detailed free quote by Boris to the very professional install by Kam and his assistant, to the all the paperwork completed by Boris for the rebates you pretty well cannot ask for any more. Now lets see how well this unit stands the test of time.
