I have been using Clean Air Heating and Air Conditioning for about two or three years now. Prior to them, I had the same person doing my heating and air conditioning work for 20 years or so. But, he took ill, and he recommended Clean Air Heating and Air Conditioning to me. I trusted his judgment, so I went with them. I have not been disappointed. They have done a good job for me. Their prices are in line with everybody else's. Their workers are polite and courteous, and they show up on time. They clean up behind themselves, and do not leave any kind of a mess in the house. There are two different men who come out to do the work, and one of the them is very careful to explain things to me. The other is less talkative, but he does good work, too. So, all in all, I am a satisfied customer.
