Tips for End of Season San Diego Furnace Maintenance & Inspections

share

Spring is almost here, and though nights are still chilly here in San Diego, it’s time to think about making sure your furnace is clean and trouble-free for next fall’s first cold snap. So here are a few tips that the professionals at Anderson Plumbing, Heating and Air recommend for end-of-season maintenance:

Gas Furnaces - Maintenance and Safety

Check around the furnace for evidence of gas leaks, which will leave stains. Make sure that you have a carbon monoxide detector near the furnace. If an alarm from the detector would not be easily heard from main rooms of the house, place another detector closer to living areas. Before you turn off the gas for the summer, check to see that the pilot light is deep blue. Any other color indicates that it is not burning properly.

Replace Furnace Filters

The end of the season is the ideal time to replace the filter in gas and electric furnaces. Make sure that the new filter is the correct size for your furnace, as a too-small filter will allow allergen-laden, unfiltered air to flow around the filter and right back into the house. Turn off the power before changing out the filters. If your air ducts haven’t been cleaned within the last five years, this is also a good time to have that done.

Clean Dirt from Furnace Area

Sweep or vacuum out dust and debris from the bottom of the furnace. Make sure to clean in crevices and corners as well.

Check Your Furnace Blower Belt

Inspect the fanbelt on the blower for cracks or fraying, and replace it if necessary. Also, check the tension of the belt—it should not give more than ½” when pressed. If it’s too loose, it should also be replaced, unless the slack is caused by the blower motor’s shifting. In that case, you may wish to loosen the bracket attachment, shift the motor until the belt is taut, and re-tighten the attachment.
