Typical Heating System Issues

Forced-air systems may encounter multiple issues over time. Here are some of the most common malfunctions I handle in my work:

  • Furnace Won’t Turn On – This can be caused by a faulty thermostat, tripped circuit breaker, or ignition issues.
  • Poor Heat Circulation – Dirty filters can cause the system to overheat.
  • Strange Noises – Whistling or grinding sounds often indicate a loose component.
  • Short Cycling – This can result from a dirty filter.
  • Gas Burner Won’t Stay Lit – A faulty thermocouple can prevent the furnace from igniting properly.

Basic Furnace Maintenance Tips

Regular maintenance is important to keep your furnace running. Here are some key maintenance recommendations:

  1. Maintain Proper Airflow
  2. A blocked air filter limits airflow, causing inefficiencies. Change the filter at least quarterly.
  3. Keep the Blower Fan in Good Condition
  4. The blower motor distributes warm air throughout the house. Dust buildup can cause wear and tear.
  5. Ensure Accurate Readings
  6. A malfunctioning thermostat can lead to frequent cycling. Monitor the battery life to verify the system is operating efficiently.
  7. Check for Cracks or Damage
  8. A cracked heat exchanger can leak carbon monoxide—a potentially deadly hazard. Should you detect soot buildup, call a professional immediately.
  9. Maintain Unobstructed Airflow
  10. Clogged vents or flue pipes lead to inefficiencies in the system. Remove obstructions to ensure proper operation.
  11. Book a Yearly Furnace Checkup
  12. A yearly checkup by a licensed HVAC technician catches major issues. This covers checking electrical components.

While some maintenance tasks are doable by homeowners, complex furnace problems must be handled by a licensed expert. Here’s when:

  • There’s No Heat – If resetting doesn’t fix the problem, you need expert help.
  • There’s a Strong Unusual Smell – Shut off the furnace immediately.
  • Unusual Sounds Persist – Grinding sounds indicate motor failure.
  • Your Furnace is Running Less Efficiently – Higher costs may indicate inefficiencies.

Final Thoughts

Taking care of your heating system guarantees reliable heating and improves the system’s lifespan. Following these maintenance tips avoids sudden breakdowns. Still, for major issues, don’t hesitate to call an HVAC professional. A licensed HVAC specialist is trained to handle serious heating system problems and ensure optimal heating.
