My air conditioner was making this funny, squeaking sound, so I called Texas Air Authorities, Inc. to come out and have a look. This was the first time that I ever used them. They showed up on time, and were very professional. And very friendly people, too. The tech was great. He was very informative and laid out all my options for me. He walked me through, step by step, and when he was finished with his explanation, I had a good understanding of what was going on. I really appreciate how he took the time to do that!
