What They Say

  • Ray with Third Coast Air & Heat goes above and beyond to do the work timely & complete. He makes suggestions to improve the air system quality and efficiency. We were totally impressed with his workmanship and communication, and the job costs are very reasonable. Will 100% recommend his service to others! Thank you Ray!

  • We have found the owner, Ray Mehrens, to be of the highest moral integrity. In addition he is very dependable and trustworthy. We have recommended this company to our family and friends.

    Ron H.

  • Thank you for being honest and hardworking. We had received a quote from a competitor - they recommended a full unit replacement at $15,000. Not only did Ray tell us we didn’t need a new unit, he said ours was still under warranty (something the other company failed to tell us). Ray recommended that we insulate the house better. Ray put insulation into our attic and did some outside ventilation work. Now that we are in the heat of summer, not only is our house cooler than it was in the past, but our electric bills are lower! We have told all our friends about Third Coast Air! They are now our go-to company. We appreciate you and the work you did. It used to take out house until well after 10 pm for the ac to stop running. Not the case any longer!

  • Thank you so much for working on my a/c. It was like you weren’t ever there! Which is a good thing. You didn't leave ANY lights on, no insulation all over the bathroom floor, a/c wasn't cranked down to 60– nothing! I am not used to someone being so conscientious about their work. Thank you Thank you Thank you!!
