Common Furnace Problems

Forced-air systems often experience several failures over years. Here are some of the usual malfunctions I come across in my work:

  • No Heat Coming from Furnace – This can be caused by a malfunctioning thermostat, tripped circuit breaker, or ignition issues.
  • Limited Warm Air Output – Clogged vents can cause the system to overheat.
  • Strange Noises – Clanking or rattling noises could mean a loose component.
  • Short Cycling – This may be caused by a dirty filter.
  • Gas Burner Won’t Stay Lit – A faulty thermocouple could hinder the furnace from producing consistent heat.

Routine Furnace Upkeep

Regular maintenance is critical to prevent costly breakdowns. Here are a few essential maintenance recommendations:

  1. Maintain Proper Airflow
  2. A blocked air filter limits airflow, causing inefficiencies. Inspect the filter as recommended by the manufacturer.
  3. Ensure Proper Fan Operation
  4. The blower motor pushes warm air via the ductwork. Debris can cause wear and tear.
  5. Calibrate Temperature Controls
  6. A malfunctioning thermostat might result in heating inefficiencies. Check the temperature settings to ensure the system is responding accurately.
  7. Inspect the Heat Exchanger
  8. A cracked heat exchanger poses a risk of carbon monoxide—a potentially deadly fume. Should you detect soot buildup, shut off the furnace and seek expert help.
  9. Ensure Proper Ventilation
  10. Clogged vents or flue pipes lead to dangerous backdrafts. Check vents regularly to avoid heating problems.
  11. Book a Yearly Furnace Checkup
  12. A yearly inspection by a certified HVAC technician helps prevent major failures. This includes testing safety controls.
