Common Furnace Problems

Furnaces may encounter multiple failures over time. Here are some of the usual malfunctions I handle in my work:

  • No Heat Coming from Furnace – This might happen due to a malfunctioning thermostat, tripped circuit breaker, or ignition issues.
  • Weak or No Airflow – Dirty filters can restrict airflow.
  • Strange Noises – Banging or rattling sounds might suggest a problem with the heat exchanger.
  • Frequent Cycling – This could be due to a improper thermostat setting.
  • Gas Burner Won’t Stay Lit – A clogged ignition port can prevent the furnace from staying on.

Routine Furnace Upkeep

Consistent maintenance is important to keep your furnace running. Here are the best maintenance practices:

  1. Maintain Proper Airflow
  2. A dirty air filter restricts airflow, leading to overheating. Change the filter as recommended by the manufacturer.
  3. Keep the Blower Fan in Good Condition
  4. The circulation system pushes warm air throughout the house. Debris can cause wear and tear.
  5. Test the Thermostat
  6. A malfunctioning thermostat might result in unbalanced temperatures. Check the battery life to verify the system is responding accurately.
  7. Check for Cracks or Damage
  8. A cracked heat exchanger can leak carbon monoxide—a serious hazard. Should you detect soot buildup, shut off the furnace and seek expert help.
  9. Maintain Unobstructed Airflow
  10. Blocked vents or flue pipes may result in inefficiencies in the system. Remove obstructions to ensure proper operation.
  11. Book a Yearly Furnace Checkup
  12. A yearly tune-up by a qualified HVAC technician helps prevent potential problems. This covers cleaning the burner assembly.
