Quick answer
Homeowner tasks: check the filter monthly during heating season, keep registers and returns clear, keep the furnace area clear, keep outdoor vent terminations free of snow and ice, and test carbon monoxide alarms per their manufacturer's instructions. Technician tasks: combustion and flame-sensing checks, temperature rise, blower amp draw, safety control verification, venting and condensate inspection.
Monthly, during heating season
- Look at the filter and replace it per manufacturer guidance when loaded.
- Walk the house and confirm registers are open and unobstructed.
- Listen for new noises at startup and during the blower cycle.
- Check that nothing has been stored against the furnace.
Seasonal, at the start and end of winter
- Clear snow and ice from high-efficiency intake and exhaust terminations after storms.
- Review the thermostat schedule for the season.
- Confirm return grilles are not blocked by furniture rearranged over the summer.
- Test carbon monoxide and smoke alarms per manufacturer instructions.
Annual, with a technician
- Temperature rise measured against the data plate range.
- Flame signal measured and compared to the minimum.
- Burner condition and flame appearance inspected.
- Blower wheel condition and motor current checked.
- Limits, pressure switches and interlocks verified.
- Venting and condensate path inspected.
Off the checklist entirely
- Do not open sealed combustion compartments or remove burners.
- Do not adjust gas controls or piping.
- Do not bypass safety switches for any reason.
