If you want terrific service just give Texas Air Authorities, Inc. a call! My air conditioning unit went at the worst time with triple-digit temperatures and my wife who is pregnant just could not take it. I had called several AC companies and no one would come out the same day and they charged a ridiculous amount as well. Not Texas Air Authorities, Inc. They came out right away and diagnosed the issue. It turned out that there was some burned wiring and parts that had to be replaced. They took care of everything with the insurance company for me. Because my system is an older system they had to order the parts for the replacement which only took one day! They were back the very next day and had me up and running within 45 minutes! They were absolutely the best price and the quickest to arrive! I have kept all of their information for future repairs or future upgrades to my system! Very nice company, extremely helpful and I will be using them again!
