STAY AWAY!!! These guys will lie to your face, again and again. Had an AHS warranty and the guy shows up in a hurry. Then makes a diagnosis and says part will be in tomorrow, and he'll be back to install. 8 days have passed int he middle of February, and for 5 consecutaive days, same story...part's being overnighted and we'll repair tomorrow. Then they blame the parts supplier saying that it came in, but they lost it. Sure buddy. Do yourself a favor...DO NOT RENEW WITH AHS AND DO NOT LET UNITED AIR TEMP WORK ON YOUR PROPERTY. You've been fairly warned. PS...another reputable HVAC company came out and repaired the issue in 1 day. read full review »
