Signs Your Furnace Isn't Working Properly

If you notice any of the following, it’s time to call a professional for a heater repair or furnace installation assessment:

  • Strange Noises: Banging, rattling, or squealing sounds coming from your furnace.

  • A Yellow Pilot Light: The pilot light should be blue. A yellow flame can indicate a carbon monoxide issue, which is a serious safety hazard.

  • Cold Air or Low Airflow: The unit is running but not producing heat, or the airflow is weak.

  • Frequent Cycling: The furnace turns on and off too often, a symptom of an underlying problem.
