A fall heating checklist contains the furnace maintenance issues you’ll want to address before the cold winds blow. Furnace malfunctions are most likely to occur at one of two times: the first startup of the season or the coldest spell of the winter. Having a trained HVAC professional deal with the former greatly reduces the chances you’ll need him for the latter. In addition to ensuring you get maximum energy efficiency and cozy winter comfort all season long, the items on a fall heating checklist are designed to identify incipient problems now – instead of an emergency call on a freezing night in February. Here’s what’s included on a typical fall heating checklist:
- Replace the system air filter. For the rest of the heating season, you should do this yourself monthly. Ask the technician to show you if you don’t know how.
- Inspect and clean fan blower blades and check the belt for adjustment and wear. Lubricate moving parts including the blower motor (if it has lubrication ports).
- Check the thermostat calibration. Verify that it signals on and off cycles to the furnace.
- Use professional techniques to evaluate the heat exchanger for cracks. A cracked heat exchanger can leak dangerous combustion gases including carbon monoxide into the house.
- Verify proper operation of the high limit switch and other controls that shut down the furnace automatically in the event of dangerous temperatures or other malfunctions.
- Inspect the vent flue for obstructions all the way to the roof.
- Check the manifold gas pressure. Low pressure may indicate a leak in a buried gas line or a defective regulator.
- Remove, inspect and clean the burners.
- Clean deposits off the thermocouple then test with a voltage meter.
- If a standing pilot light is installed, check for proper operation. Test the electronic igniter, if installed.
- While the furnace is running, test the interior environment for carbon monoxide levels.
