This was our first-time using Texas Air Authorities, Inc. We had a bad experience with the first company we were using so my husband looked at reviews online and we found Texas Air. We have a home that requires air conditioning with zoning and ours needs four zones. Most companies here will only do two zones. Texas Air Authorities, Inc. was willing to take on the task of doing the four zone, they were knowledgeable, honest and ethical. We now have a set contract with them for our seasonal checks as well. Their workers were cordial and pleasant. We did have a small incident but even that was completely addressed by them on all fronts. They made this whole process painless and they completed it in less than two days for four zones! I would definitely recommend Texas Air Authorities, Inc.!
