Furnace Filter become clogged faster than Usual… Part3

High levels of indoor contaminants:

High levels of indoor air pollutants create a bigger burden for furnace filters and they become clogged much faster. Filters typically don’t last as long in homes with indoor pets or where indoor smoking takes place. Weatherizing the home to prevent winter heat loss traps contaminants indoors which can increase this issue.

If you haven’t changed your winter filters out yet, you may want to start thinking about it soon. If you are unsure what filters you need, or you would prefer a professional Licensed HVAC company to come out and do a service call, please call us here at AC Dave Heating & Air. We are here to serve.

20 Most Common Winter Heating System Problems March 7

The furnace filter becomes clogged faster than usual 

Air filters need to be replaced on a regular basis, as filters become clogged with contaminants pulled from circulating air. It is normal for filters to require more frequent replacement during the winter months due to increased heating system operation – however, abnormal issues may cause your filter to become clogged sooner, requiring replacement much earlier than expected. It is recommended to replace your filter a minimum of twice a year.

  • The blower fan is set to ON. When the fan is set to ON at the thermostat, the blower runs continuously. As air constantly circulates through the HVAC system, it completes more passes through the filter, and the filter fills with contaminants at a faster rate. Turning the fan to AUTO is a furnace troubleshooting step that can help filters last longer.
  • Duct leaks. Duct leaks allow more contaminants into the indoor air supply from the unconditioned areas surrounding the ductwork. With more contaminants in the air, the filter will fill faster as air circulates.
  • Dirt accumulation near return air vents. The home’s return air vents feed indoor air back to the heating system for conditioning. Accumulation of dirt on or around the return air vent introduces more contaminants to the air supply and forces the filter to fill at a faster rate in order to keep them out of the heating system.

High levels of indoor contaminants. High levels of indoor air pollutants create a bigger burden for furnace filters and they become clogged much faster. Filters typically don’t last as long in homes with indoor pets or where indoor smoking takes place. Weatherizing the home to prevent winter heat loss traps contaminants indoors, which can increase concentrations of indoor air contaminants.
