I have always been very impressed with everyone at Air Conditioning Sales of Norman! They are polite, respectful and, most importantly, reliable! They have had to come out to my house in the middle of the night, when we were all freezing because my heating unit went out. They showed up, as courteous and professional as ever... and I didn't have to give up my first born for payment! They really have reasonable rates, and for the quality of work you receive, I would say their rates are better than most others!
