Frequent Furnace Malfunctions

Heating units can develop various failures over extended use. Here are some of the most common challenges I come across in my work:

  • Furnace Won’t Turn On – This can be caused by a malfunctioning thermostat, damaged circuit breaker, or pilot light problems.
  • Weak or No Airflow – Blower motor problems can reduce efficiency.
  • Loud Furnace Operation – Whistling or squealing sounds might suggest a failing blower motor.
  • Furnace Turns On and Off Too Often – This can result from a improper thermostat setting.
  • Gas Burner Won’t Stay Lit – A gas supply problem may stop the furnace from igniting properly.

Basic Furnace Maintenance Tips

Proactive maintenance is necessary to maintain heating efficiency. Here are some key maintenance tips:

  1. Check and Replace Air Filters
  2. A blocked air filter limits airflow, forcing the furnace to work harder. Inspect the filter at least quarterly.
  3. Inspect and Clean the Blower Motor
  4. The fan moves warm air into your living space. Dust buildup can reduce efficiency.
  5. Ensure Accurate Readings
  6. A malfunctioning thermostat can lead to frequent cycling. Check the connectivity to verify the system is functioning properly.
  7. Check for Cracks or Damage
  8. A damaged heat exchanger poses a risk of carbon monoxide—a dangerous fume. If you notice soot buildup, shut off the furnace and seek expert help.
  9. Keep Vents Clear
  10. Clogged vents or flue pipes may result in dangerous backdrafts. Inspect airflow pathways to ensure proper operation.
  11. Schedule Annual Professional Maintenance
  12. A yearly tune-up by a licensed HVAC technician reduces the risk of expensive failures. This includes testing safety controls.
