I first started used A & R Air Conditioning last year when they put a new unit in for me. This year, it was just a checkup and maintenance call for warranty purposes. Everything was great except for a lot of ash in the coils, but he cleaned it all out and everything is working the way it should now. I was very happy with A & R. I really like their work. They are prompt, courteous, and clean, and I definitely recommend them!
