Essential Furnace Upkeep: Expert Advice from an HVAC Technician

As an licensed professional, I regularly work on furnaces that aren’t working properly. A well-maintained furnace also provides efficient heating but also reduces costly repairs. In this overview, I’ll share frequent heating system issues, routine maintenance tasks, and when to call a professional.

Common Furnace Problems

Heating units can develop multiple failures over time. Here are some of the usual malfunctions I come across in my work:

Furnace Won’t Turn On – This could be a result of a malfunctioning thermostat, tripped circuit breaker, or sensor failure.
Poor Heat Circulation – Dirty filters can restrict airflow.
Strange Noises – Whistling or squealing sounds could mean a loose component.
Furnace Turns On and Off Too Often – This may be caused by a dirty filter.
Pilot Light or Ignition Issues – A faulty thermocouple may stop the furnace from igniting properly.

Routine Furnace Upkeep

Consistent maintenance is critical to keep your furnace running. Here are a few essential maintenance recommendations:

Maintain Proper Airflow
A blocked air filter reduces airflow, forcing the furnace to work harder. Change the filter every 1-3 months.
Ensure Proper Fan Operation
The fan distributes warm air into your living space. Dust buildup can cause wear and tear.
Test the Thermostat
A miscalibrated thermostat can lead to unbalanced temperatures. Monitor the temperature settings to ensure the system is operating efficiently.
Inspect the Heat Exchanger
A damaged heat exchanger can leak carbon monoxide—a serious gas. Should you detect unusual smells, schedule an inspection.
Keep Vents Clear
Blocked vents or flue pipes lead to poor heating performance. Remove obstructions to maximize efficiency.
Schedule Annual Professional Maintenance
A yearly inspection by a certified HVAC technician reduces the risk of major issues. This covers checking electrical components.
