Common Furnace Problems

  • No Heat: One of the most jarring issues is when your furnace fails to produce heat at all. This could be due to several factors, including a malfunctioning thermostat, a tripped circuit breaker, or a clogged filter.
  • Inconsistent Heating: If some rooms in your home are warm while others remain chilly, it might suggest a duct issue or uneven airflow.
  • Strange Noises: Unusual sounds, like banging or squealing, can indicate mechanical failures or loose parts that require immediate attention to prevent further damage.
  • Short Cycling: If your furnace frequently turns on and off without completing a cycle, it may be overheating. This could be due to a dirty filter, a malfunctioning limit switch, or simply an undersized unit.
