Absolutely awful! I'm also a customer of American Home Shield, and they sent an Air Pro Master tech (Jose) out to my home. After misdiagnosing the problems with two of my a/c units and charging me over $400 for freon, he left having repaired nothing! Another tech from another company came out and fixed the problem in one unit in 15 minutes. When I went back to AHS to get the unresolved problem fixed, Air Pro Master had AHS deny the claim, only to call and try and charge me extra money to do the job outside of my warranty. Steer clear of this company if you actually want good service and don't want to waste money. If I could give less than a star, I would.
