How do you change an furnace filter?
Modern central heating and air conditioning systems generally have the filter located as close to the blower unit as possible, in the
cold air return duct. Remove the grill or box cover holding your filter in place.
Remove the dirty filter:
Dispose of the dirty filter in a bag to contain the dirt.
Install the new or cleaned and dried furnace filter with the air flow arrow pointing toward the blower. Record the date and wash or change the filter within the recommended period.
If you experience higher dust levels in your home due to changes in outside air, construction or dry weather, you may need to change or wash your filter more frequently than the recommended period.
For questions or concerns about the location or installation of the filter contact the HVAC manufacturer or a reputable HVAC contractor.
