Found and called AC Doctors based on their standing on Yelp, and I'm so glad I did. There's a reason they are ranked number one. Just like in auto mechanics, the most important quality needed in an AC tech is honesty. Before they came out, I had two AC techs from other companies telling me I needed to install a completely new system. Pete and Nestor from AC Doctors were punctual, professional and did not overcharge me as they took a least invasive approach towards getting my AC back and running before moving towards a new system install. Additionally, Doug (the owner) is an incredibly nice, approachable guy, and their office staff (Annette) was very helpful. So glad I found a go-to company to perform maintenance on something so essential while living in Arizona.
