Furnace Not Heating

Professional Furnace Not Heating in Asheville & Western NC

A furnace that runs its cycle but doesn't produce heat is a common and frustrating problem, especially when temperatures drop in the mountains. Quality Comfort's technicians are experts at diagnosing 'furnace won't heat' problems quickly and accurately. The most common causes include a failed ignitor (the most frequent furnace repair we perform), a faulty flame sensor that's covered in oxidation and can't detect a flame, a failed thermocouple on older standing-pilot systems, a tripped limit switch due to overheating from a clogged filter or poor airflow, a faulty gas valve, or a cracked heat exchanger that has triggered a safety shutoff. Some of these are straightforward fixes; a cracked heat exchanger, while less common, is a safety issue requiring prompt attention. Whatever the cause, we'll diagnose it accurately and explain your options clearly.
