Step 1: Turn off the Furnace

Turning off the furnace is an important step to ensure your safety while working on the furnace. You can turn off the furnace at the thermostat or by switching the circuit breaker. 


Step 2: Locate the Filter

The filter is typically located in the blower compartment or the air return duct. Refer to your furnace manual or contact our professional HVAC contractors for assistance!

Step 3: Remove the Old Filter 

Remove the old filter by sliding it out of the filter slot. Take a moment to inspect the old filter to see how dirty it is, as this can help indicate if you need to change the filter soon next time. On average, you should change your furnace filter every 90 days.

Step 4: Install the New Filter

After removing the old filter, it’s time to install your new one! Ensure the filter is facing the correct direction by checking the airflow arrow printed on the filter. Slide the new filter into the filter slot, ensuring it fits into place.

Step 5: Turn On the Furnace

Once the new furnace filter is properly installed, the final step is to turn on the furnace. Turn on the thermostat the same way you turned it off, either at the thermostat or by switching on the circuit breaker.
