I could not be more pleased with the service and results from Taps and Antrim Air. I have a commercial office building in Scottsdale under a "service" contract with another one of the big boys in AC. When they came out and told me I needed a completely new unit at about $5,000. I got a few other opinions and am I glad I did! The diagnosis and repair was done within two days at less than a third of the cost! It's adios to my old company - Antrum Air is my new AC service pro.
