This was our first time using Texas Air Authorities, Inc. They came out to service our heating and air conditioning unit and they did a really good job. The technicians were pleasant, professional and prompt. They were respectful of our home and answered the few questions that we had. Work with HVAC units is not cheap but you do get what you pay for and Texas Air Authorities, Inc. is a great company with knowledgeable representatives that know what they are doing. We absolutely recommend using them!
