Warning Signs of a Failing Furnace

Furnaces in Los Angeles sit idle for 8 months out of the year. When they finally fire up, dust buildup and thermal stress can cause critical components to fail.

  • Yellow Burner Flames Gas should burn crisp and blue. A yellow or wavering flame indicates incomplete combustion and potential carbon monoxide production.
  • Short Cycling If your furnace turns on and shuts off after just a few minutes, the high-limit switch is likely tripping to prevent an overheat scenario.
  • Ignition Failure Clicking noises with no heat usually mean a dirty flame sensor or a failing hot surface ignitor.
