Coolray Heating & Air Conditioning installed the geothermal system which came with the home we purchased. So, when we wanted to install a heating system in the basement, we called them. Their salesman was very professional and very knowledgeable. He knew exactly what he was talking about and he helped us decide on a ventless heating system for the basement. Their service people were very friendly and very well-skilled and they did a great installation job for us. We were very satisfied, and we highly recommend Coolray Heating & Air Conditioning!
