Furnace Maintenance Checklist

Now that fall is here, it's time to switch from using your air conditioner to use your heater. Make sure you and your family won't be cold this autumn and winter by scheduling your yearly furnace check and tune-up. Annual inspections and maintenance by a trained professional are recommended by all furnace manufacturers. Having your unit serviced once a year will also help it last longer. Professional care performed once a year is required to maintain the guarantee from one year to the next.

1. Replace the filter in your furnace monthly.

Because of the potential for catastrophic failure due to overheating, it may be necessary to replace the heating system altogether. Filters get clogged when dirt and debris accumulate, preventing air from flowing freely and forcing the system to work harder than necessary. When filters get clogged, debris cannot pass through and accumulates elsewhere in the system, leading to contamination and costly maintenance costs.

2. The belt should be inspected for wear and replaced if necessary.

Technicians will repair or realign any furnace belts that are worn or out of place to ensure the blower motor can do its job. As a properly running blower motor is essential to distributing warm air throughout a house, homeowners benefit from furnace repair when the belt is examined.

3. The bearings in your furnace's blower should be oiled once a year.

Most modern motors are factory pre-lubricated and sealed, so you never have to worry about them. However, some motors have covered oil openings near the motor shaft. The motor should be oiled once a year if it has oil ports. Alternatively, if it contains grease cups, you may fill them with bearing lubricant after removing the screw covers that cover them.

4. Check the furnace's burner and swap it if it's worn out.

Inspecting the burner is an essential aspect of a well-maintained furnace that should be done annually by a professional HVAC technician. By collecting and evaluating combustion gas samples, the technician can ensure the burners are working as they should. Professional cleaning of a gas furnace's burner may be necessary at regular intervals to maintain efficiency and ensure safety.
