What customers say about furnace repair
…This is during the winter freeze over the weekend(1/25/26) called other companies in desperate need and Air star Now came to the rescue seriously and not only came to evaluate but actually showed and explained everything we needed to know. They installed a new furnace and the install is clean and professional. From now on I’m only calling Air Star now for my hvac services. Thanks to everyone that came out and got us the gift of heat. I can not say thank you enough. Also take advantage of their membership program…

What customers say about furnace repair
…Regardless of the type of units installed, the AC was loud when it turned on and the house was simply not cool enough. We could never get the temp to be lower than 79 degree no matter how long the AC was kept running. Last year, we had the furnace, compressor, and coil replaced, but the problems remained. What’s worse, the drain line kept getting clogged, shutting down the AC altogether. For several nights I had to take a wet vacuum to suck up all the water in the pan so that we won’t be without AC. It was a nightmare…

What customers say about furnace repair
H-town did a great job putting in an AC/furnace system in a tight space. My old AC was broken and we needed a new unit. I received many estimates, and theirs was among the best. They were very upfront about pricing and did not try to upsell things I did not need. AC units definitely need to be protected from power surges, but they happily removed that charge to bring the price down and admitted that I did not need the extra surge protector since I have a whole house surge protector on my house electrical panel…

We had a new AC, furnace and ductwork installed. The best experience. They were very thorough with their estimate which I appreciateed. Very professional. I needed an adjustment in one of the rooms and they came out the same day I called. We are so pleased with the new system. It's awesome. We found their prices to be fair as well. I highly recommend them

You won’t find a better professional company for your furnace needs. Zach was the technician who came out to my house, and he was awesome. He walked me through his normal inspection routine, explained what I should do moving forward, and had all the costs upfront with no surprises. Zach was very professional and patient—he didn’t even mind that I followed him around like a lost puppy while he worked! He took the time to explain everything clearly, which I really appreciated. I actually heard about the company on AM radio during an interview with a fellow named Rusty, and I’m glad I did…

What customers say about furnace repair
A year and a half ago, we had Air-Current replace one of our old air conditioners and the furnace in our home. They did such a great job that we had the second zoned units replaced a couple of weeks ago. Stan (the owner) answered all the questions that we had (and there were many) thoroughly. Cameron handled our financing (and made the process very easy). James (the general manager) and the crew did an excellent job with the installations. They even cleaned and repaired our dryer vent…

We don’t use the heater much in Houston, so when it stopped working I had no idea who to trust. Kenny from 75 Degree AC came out and handled the furnace repair in Houston fast and without trying to sell me anything extra. Very professional, very honest. I really appreciate that kind of service

What Every Houston Resident Should Ask Before a Service Call
- When is a furnace problem an actual emergency vs. a next-day call?
- Carbon-monoxide alarm, smell of gas, or visible cracks in the heat exchanger → emergency. No-heat in sub-freezing weather is urgent but rarely safety-critical. Most no-heat calls are igniter, flame sensor, or gas valve — same-day fixable.
- What's the difference between a flame-sensor clean ($120) and heat-exchanger replacement ($1,500+)?
- Flame sensors clog with combustion residue and stop signaling the gas valve — quick clean or swap. Cracked heat exchangers leak CO into your home airflow and require exchanger replacement (often impractical) or full furnace replacement. The tech's CO meter reading decides which one you're facing.
- Is a city-issued permit required for HVAC system replacements in Houston?
- Yes, the Houston Permitting Center requires a mechanical permit for most HVAC system replacements and significant modifications to your home's cooling infrastructure. Licensed contractors are responsible for securing these permits to ensure the installation meets local building codes and safety standards. Always verify that your chosen provider handles the permitting process, as this protects you from potential liability and ensures the work is properly inspected.
- When is the peak season for HVAC maintenance in Houston?
- The busiest season for HVAC maintenance in Houston, Texas, occurs during the peak of summer and throughout the hurricane season from June through November. Extreme heat and tropical humidity cause high demand for emergency repairs and system tune-ups. Scheduling your annual maintenance well before the summer heat intensifies can help you avoid long wait times and ensure your system is prepared for the high-stress conditions common in our climate.
- How do I find a qualified specialist for thermostat installation in Houston?
- Look for providers who demonstrate expertise in smart home integration and variable-speed system calibration when searching for thermostat installation in Houston. A qualified technician should be able to verify compatibility with your existing HVAC equipment and ensure the new device is correctly configured for local humidity management. Check for NATE-certified professionals who have experience working with modern, energy-efficient controls that help manage the unique cooling loads found in neighborhoods like the Heights or West University Place.
- How much does HVAC service cost in Houston, TX?
- Furnace repair typically runs $135–$760, and heat exchanger replacement runs $1,350–$3,100 in Houston, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
