I have been using Tri County Climate Control for six years. This last time they were out was for annual maintenance on my air conditioning unit. It's a new one that they installed for me last year. It all turned out fine. They have always done great work for me. They've always been dependable, and their techs are always personable and answer all my questions. Also, they respond very quickly by email so you can communicate with them that way, and it's very convenient. I highly recommend them!
