Cleveland HVAC Testimonials
"We had a furnace,air,whole house humidifier and air cleaner all installed today. We are very pleased with Ken and his associate. Ken has always been honest when we needed repairs on the old one. We never shopped around because when he said he would be here at a certain time he was. I was not at all afraid to leave him if I had to. I trust and recommend him and his work. He was through and cleaned up after and also used drop cloths in the house which I appreciated. I would highly recommend Ken. IU"
