DO NOT USE THIS COMPANY!
Arizona Trade Masters was recommended to us by APS. The "technician" came out, never stepped foot in my house to take readings, went onto the roof, claimed he had to "try to restart my AC" and that it was completely dead. Over the next few days, I received a vague quote of "$3300" - containing no specific details for replacing the entire unit. Just to be safe, I decided to get a second option. It turns out, my cold air return was blocked just enough that it was preventing my AC unit to work properly. In fact, the 2nd opinion tech stated I had one of the newest units on the roof. So basically, either your technicians know nothing about HVAC, or this company is trying to scam people out of thousands of dollars. Either way, I will be reporting you to APS and BBB.
