Air-Zona was recommended to me by a friend. I am very impressed. My air conditioning quit over the weekend, and I called and asked for someone to come out first thing Monday. (They would have come out on Sunday, but I wasn't going to be home anyway.) Daryl showed up right on time and looked over everything. He was a super nice guy and he wasn't bothered when I asked questions, and he offered plenty of information. It was a pretty simple fix, but he took the extra time to clean everything up and check everything out, and give it a good once over. Now it is blowing nice and cold! These guys are definitely my go-to for A/C stuff from now on.
