I had problems with my a/c all summer. I had Brad the handyman out and he couldn't fix it. Then Precision from Chandler who changed a capacitor and still my a/c lines were freezing up. On my 4th call I tried AccuTemp. Mike came out and determined I had a clog in the expansion value. He cleaned it up and the a/c has been running great since. I would definitely use this company again.
