I've had problems since I first bought this place brand new. The original company came out one time to fix said it was fixed near the end of summer. It wasn't fixed another  company came out  charged me  500 to fix . a few days  later  it was  broke again. I called glacier the guy came out he  was here about 2-3 hours! That's 2 hours longer than the other guys!  He told me there was wires  pinched at outdoor machine then wired wrong in Attic. He repaired and now I haven't had any problems  since . That was 3 months ago. Less than 300.00 Great work ! Great company!
