The furnace that heats your house is an impressive machine, but it does require some maintenance. Maintenance should be performed every 3-6 months in order to clear out dust which can cause problems ranging from less efficiency to catastrophic meltdowns. Here’s a step-by-step list to tackle your furnace maintenance.
The furnace filter is the most susceptible to a buildup of dust. This can restrict airflow and eventually cause overheating.
Before doing any work on your furnace, turn off the power and gas lines to the machine. Pull the filter out, noting the direction it’s facing. Check the manual for the right dimensions and MERV rating, get a new filter, and pop it into place in the proper direction.
Clean and Inspect the Heat Exchanger
To clean and inspect the heat exchanger, you need to remove the cover panel. Use a vacuum to suck up all the dust, and a toothbrush to reach nooks and crannies. Check for any cracks in the piping or burn marks. This can indicate a carbon monoxide leak or flame overflow. If you notice these signs, call a professional.
To clean the blower, remove the blower cover panel, disconnect the motor wires, and remove the control board. Slide the blower assembly out and use a brush and vacuum to clean. Slide everything back in, in reverse order, and screw back on all the cover panels.
When everything’s set, you can turn back on the power and gas and your furnace will be as good as new!
