Heating System Service and Care: Guidance from an HVAC Technician

As an heating expert, I regularly service furnaces that need maintenance. A properly functioning furnace not only provides consistent heating but also prevents breakdowns. In this article, I’ll share typical heating system issues, routine maintenance tasks, and situations requiring an HVAC technician.

Frequent Furnace Malfunctions

Forced-air systems can develop various failures over extended use. Here are some of the most common malfunctions I come across in my work:

  • Furnace Won’t Turn On – This could be a result of a worn-out thermostat, damaged circuit breaker, or sensor failure.
  • Poor Heat Circulation – Blower motor problems can restrict airflow.
  • Strange Noises – Banging or squealing sounds often indicate a problem with the heat exchanger.
  • Furnace Turns On and Off Too Often – This may be caused by a improper thermostat setting.
  • Intermittent Ignition Failures – A gas supply problem can prevent the furnace from producing consistent heat.

Basic Furnace Maintenance Tips

Proactive maintenance is necessary to keep your furnace running. Here are some key maintenance tips:

  1. Maintain Proper Airflow
  2. A blocked air filter limits airflow, causing inefficiencies. Replace the filter every 1-3 months.
  3. Ensure Proper Fan Operation
  4. The fan pushes warm air into your living space. Debris can cause wear and tear.
  5. Calibrate Temperature Controls
  6. A unresponsive thermostat can lead to unbalanced temperatures. Monitor the temperature settings to ensure the system is responding accurately.
  7. Monitor for Carbon Monoxide Leaks
  8. A damaged heat exchanger can leak carbon monoxide—a serious fume. If you notice unusual smells, call a professional immediately.
  9. Maintain Unobstructed Airflow
  10. Obstructed vents or flue pipes can cause dangerous backdrafts. Check vents regularly to ensure proper operation.
  11. Schedule Annual Professional Maintenance
  12. A yearly inspection by a certified HVAC technician helps prevent major problems. This covers checking electrical components.

When to Call a Professional

While basic maintenance tasks are doable by DIYers, serious furnace problems require professional expertise. Consider calling a professional if:

  • There’s No Heat – If troubleshooting doesn’t resolve the issue, a technician should inspect the system.
  • Gas Leaks Are Present – Evacuate and call for service immediately.
  • Unusual Sounds Persist – Grinding sounds indicate motor failure.
  • There’s a Sudden Increase in Energy Costs – Unusual energy consumption often mean a struggling system.

Summary

Taking care of your heating system guarantees consistent heating and prolongs the system’s lifespan. Following these maintenance tips can prevent costly repairs. That said, for major issues, don’t hesitate to call an HVAC professional. A qualified HVAC specialist is trained to handle dangerous failures and help your system run smoothly all season long.
