Changing the Furnace Filter

​To change a furnace filter, follow these steps:

1. Turn off the furnace: Before starting the process, make sure your furnace is turned off to avoid any accidents.

2. Locate the filter: The furnace filter is typically located near the blower motor, inside the furnace cabinet, or in a filter slot on the return air duct. Consult your furnace's manual if you're having trouble finding it.

3. Remove the old filter: Once you've located the filter, carefully slide it out or detach it from its slot. Dispose of the old filter properly.

4. Note the filter size: Take note of the dimensions printed on the side of the old filter or consult your furnace manual. This will help you determine the correct size when purchasing a new filter.

5. Purchase a new filter: Visit a hardware store or any retailer that sells furnace filters. Ensure you get a new filter that matches the size and type specified for your furnace.

6. Install the new filter: Insert the new filter into the filter slot or slide it back into the furnace cabinet, making sure the airflow direction arrow printed on the filter matches the direction of the air flowing towards the blower motor.

7. Secure the filter: If the filter has tabs, secure them in place to hold the filter steady. Otherwise, make sure the filter fits snugly without any gaps.

8. Turn on the furnace: After securely installing the new filter, turn the furnace back on and ensure it's running properly.

Remember, furnace filters should be changed regularly depending on your specific furnace and environmental factors. It's generally recommended to change them every 1-3 months to maintain the furnace's efficiency and indoor air quality.
