How Furnace Maintenance This Fall Can Prevent Problems Next Season

How Furnace Maintenance This Fall Can Prevent Problems Next SeasonSchedule professional furnace maintenance now and avoid major problems later. “Now” means the fall season, before frigid weather arrives and a furnace breakdown occurs at the worst possible time. Fall furnace maintenance is designed to identify incipient problems before they become major malfunctions later in the season. It also preserves system energy efficiency, keeps operating costs low, and ensures your family’s safety through another long winter.

Beyond changing the system air filter — something you should do yourself monthly during the heating season — fall furnace maintenance isn’t a DIY project. High temperatures, an open flame, and the potential of dangerous carbon monoxide gas restrict this important service to a qualified HVAC technician with the equipment and expertise.

A typical fall furnace checkup includes over 20 checklist items. Here are some of the major parts:

  • Remove the burner assemblies, inspect, and clean.
  • Clean the pilot sensor (if equipped) and the furnace flame sensor. If the furnace utilizes an electronic igniter instead of a pilot, test it with an ohmmeter.
  • Inspect the heat exchanger for cracks or corrosion. This critical safety component prevents carbon monoxide gas from infiltrating into the furnace airflow.
  • Test the gas pressure to the furnace and adjust if necessary.
  • Clean the blower fan of dust and dirt and check the blower drive belt for wear and correct tension. Lubricate all blower moving parts.
  • Inspect the vent pipe all the way to the roof and verify that it is fully intact and unobstructed.
  • Start the furnace and observe the burner flame for proper color and height.
  • Using a combustion analyzer, test the exhaust gases for correct carbon monoxide and oxygen levels. Check the furnace airflow for the presence of carbon monoxide gas.
  • Compare the thermostat reading to actual room temperature. Test the on and off signals of the thermostat and calibrate if necessary.

Now’s the time to schedule fall furnace maintenance so your system will be ready for another winter of safe, efficient heating. Contact the professionals at Paitson Bros., your source for furnace sales and service since 1922.
