Thermocouple Replacement in Dallas
100% Local

If your gas furnace pilot light won't stay lit, there's a good chance your thermocouple needs replacing. This safety device is small but critical—and our Dallas technicians can replace it quickly to get your heat back on.
A thermocouple is a safety sensor that shuts off gas flow if the pilot light goes out. When it fails, your pilot light won't stay lit no matter how many times you try to relight it. The good news? Replacement is usually straightforward and affordable.
Our team carries thermocouples for most furnace models, so we can often fix the problem in one visit. We'll test the new thermocouple to make sure it's working properly and check your pilot light assembly while we're at it.
Signs You Need Thermocouple Replacement
Your pilot light won't stay lit even after multiple attempts to relight it, which is the classic sign of thermocouple failure. You find yourself having to hold the pilot button longer and longer each time you try to start the furnace. The pilot goes out frequently, especially on windy days or when the furnace kicks on. If you smell gas near the furnace, call us immediately—never attempt to relight a pilot when you smell gas.

Such a great company! Quincy was extremely professional and efficient. The technician was knowledgeable and helpful explaining everything that was being done or needed to be repaired to help me understand versus just trying to send me an estimate. I highly recommend Quincy, Hayden, Jake or Ron for any HVAC needs. Thank you, Quincy again for being so amazing!

Great company to get your air conditioning done by. They were the lowest quote out of the 3 companies I had come out. The guys came out and put in a new furnace, coil, plenums, and condenser. American standard was the brand and it looks great. Ron Sanford was very professional and made sure everything was right and working before they were done.
