I recently used Clean Air Heating and Air Conditioning to have a heat pump compressor replaced. There's a lot of familiarity with the crew member, as I've been working with the same tech from Clean Air for over nine years. He's worked on my system this whole time, so he knows what he's doing, and even better, he describes to me what it is he's working on and how he's doing it. They do a good job, and I will continue using them.
