Heating System Service and Care: Guidance from an Heating Specialist

As an HVAC technician, I often work on furnaces that aren’t working properly. A regularly serviced furnace also provides cost-effective heating but also prevents breakdowns. In this article, I’ll explain common furnace problems, routine maintenance tasks, and when to call a professional.

Frequent Furnace Malfunctions

Forced-air systems often experience multiple issues over years. Here are some of the most common malfunctions I come across in my work:

  • Furnace Won’t Turn On – This can be caused by a malfunctioning thermostat, tripped circuit breaker, or sensor failure.
  • Poor Heat Circulation – Blower motor problems can cause the system to overheat.
  • Loud Furnace Operation – Clanking or squealing sounds could mean a loose component.
  • Short Cycling – This could be due to a overheating issue.
  • Intermittent Ignition Failures – A clogged ignition port may stop the furnace from igniting properly.

Basic Furnace Maintenance Tips

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

  1. Keep Air Filters Clean
  2. A clogged air filter restricts airflow, leading to overheating. Change the filter as recommended by the manufacturer.
  3. Ensure Proper Fan Operation
  4. The fan distributes warm air via the ductwork. Dust buildup can cause wear and tear.
  5. Ensure Accurate Readings
  6. A miscalibrated thermostat can lead to frequent cycling. Monitor the connectivity to ensure the system is responding accurately.
  7. Monitor for Carbon Monoxide Leaks
  8. A cracked heat exchanger poses a risk of carbon monoxide—a dangerous fume. If you notice soot buildup, schedule an inspection.
  9. Maintain Unobstructed Airflow
  10. Obstructed vents or flue pipes lead to inefficiencies in the system. Check vents regularly to maximize efficiency.
  11. Book a Yearly Furnace Checkup
  12. A yearly inspection by a qualified HVAC technician helps prevent expensive failures. This covers checking electrical components.

When to Call a Professional

While some maintenance tasks may be managed by residents, complex furnace failures should be addressed by an HVAC technician. Here’s when:

  • The System Doesn’t Turn On – If troubleshooting doesn’t fix the problem, you need expert help.
  • There’s a Strong Unusual Smell – Turn off the gas supply right away.
  • Strange Noises Are Getting Worse – Squealing sounds could mean motor failure.
  • Your Heating Bills Have Spiked – Higher costs suggest inefficiencies.

Final Thoughts

Proper furnace maintenance helps provide efficient heating and prolongs the system’s lifespan. Keeping up with routine checkups can prevent costly repairs. However, when serious problems arise, reach out to a certified technician. A licensed heating technician is trained to handle serious failures and help your system run smoothly all season long.
