Home Heating and Air Conditioning Services

In Houston, a dependable heating and cooling system is as important as having hot water or electricity. Your family spends a lot of time indoors, so it’s critical to hire a trained and certified contractor when you need HVAC service.

Heating and Air Conditioning Services

The skilled and experienced contractors associated with Third Coast Air and Heat offer a full array of heating and air conditioning services designed to keep your family healthy, safe, and comfortable in all weather conditions.

  • Complete System Design: Homeowners have suffered long enough with high utility bills and uneven levels of comfort caused by poor system design. Our technicians always run a full set of load calculations to determine the effect that windows, doors, perimeter leakage and insulation have on your home’s total heating and cooling load. Properly sized air conditioners provide better comfort, longer life and lower operating costs when compared to systems that are oversized or matched with deficient ductwork.
  • HVAC Installation Services: Any major construction project can be disruptive and inconvenient, so our technicians are trained to keep job site clutter to a minimum while maintaining a low profile. Every new construction or replacement system will have that “factory” finished look, and our technicians performance-test the equipment to ensure it delivers just the right amount of conditioned air into every room in your home.
  • Comprehensive Repair Service: It’s early morning in July, and your house is heating up when you suddenly realize your air conditioner isn’t working. You start to get that sinking feeling because you know this is going to be a major hassle. Fortunately, Third Coast Air and Heat can quickly address any HVAC equipment repair problems. We always use genuine factory-authorized repair parts, and 24/7 critical care service is available for emergencies.
  • Maintenance Agreements: Besides your house and car, your central HVAC system may be the most expensive purchase you ever make. It makes sense to protect your equipment by acquiring a preventative maintenance plan. Twice a year, certified technicians tune-up your equipment and perform a variety of critical inspections, calibrations and adjustments to ensure the system performs at peak efficiency year round.
  • Indoor Air Quality Services: Modern homes are often too tight, and older homes usually have large gaps and breaches in the perimeter envelope. In either condition, dirt, dust and other pollutants accumulate in the interior of your home where they can negatively impact those with allergies, asthma and other respiratory conditions. Third Coast Air and Heat is trained in indoor air quality science, and they can design a whole-house IAQ strategy that includes filtration, ventilation, eradication, and humidity control so your home stays clean and fresh-smelling throughout the year.

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!!
