Instructions to Change Furnace Filter
- 1). Turn off the power to the furnace.
- 2). Locate the filter housing. Read the owner's manual to find your furnace's filter location. Many furnace filters are located near the blower. Also take note of the housing unit. Check for an access panel and how it is secured to the unit.
- 3). Slide the old filter out of the furnace. Look for the airflow arrow on the side of the filter.
- 4). Install the new filter with the airflow arrow pointing in the same direction as the old filter.
- 5). Reassemble the filter housing, if necessary and turn the power back on.
