Coolray Heating & Air Conditioning recently replaced my HVAC system and the new system is working great. I had used them once before and because of the good job they did I became a repeat customer. The servicemen were knowledgeable, professional, and they did a top-notch job. When I called to have them come out; they responded quickly. I recommend them because they got the job done quickly and efficiently. Both experiences I have had with Coolray Heating & Air Conditioning were very good; I will be using them again.
