This is the second service I have had done since the initial installation of my new HVAC system. The installers were professional and got the entire system (both heat and AC) installed in 1 day. The service Tech that has come out both times has been great to work with. Great demeanor, treats my home like his own, and clearly takes a lot of pride in his work. Richard McSherry is a wonderful tech and I would highly recommend CoolRay to anyone looking for a new HVAC system for their home.
