Changing Your Furnace Filter

Changing the furnace filter is an important maintenance task that helps keep your HVAC system running efficiently and improves the air quality in your home. Here’s a step-by-step guide on how to do so!

Determine the type of filter

The first step is to identify the size of the filter your furnace requires. The size is usually indicated on the side of the existing filter or in the furnace manual.

Turn off the furnace

Before you start replacing the filter, it's crucial to turn off your furnace to avoid any accidents or damage. Locate the power switch or circuit breaker for the furnace and switch it off.

Find the filter location

The filter is typically located in the main return air duct, which is usually near the air handler or furnace. It may also be located in the blower compartment or inside the furnace itself. Refer to your furnace manual if you're unsure about the exact location.

Remove the old filter

Carefully slide out the old filter from its slot. Take note of the direction of airflow indicated on the filter frame, as this will help you install the new filter correctly.

Inspect the filter

Take a moment to examine the old filter. If it appears dirty, clogged, or damaged, it's definitely time for a replacement. A clean filter allows for better airflow and ensures that your furnace operates efficiently.

Install the new filter

Take the new filter and align it with the arrows or indicator on the filter frame, ensuring that the airflow direction matches the markings. Slide the filter into place, making sure it fits securely and snugly.

Turn on the furnace

Once the new filter is installed, you can turn the furnace back on. Flip the power switch or reset the circuit breaker. Allow the furnace to run for a few minutes and check for any unusual noises or issues.

Set a reminder for future replacements

Furnace filters should be changed regularly, typically every one to three months, depending on the type of filter and the air quality in your home. To avoid forgetting, set a reminder on your calendar or smartphone.

Remember, regular filter changes are essential to maintain the efficiency of your furnace and ensure clean and healthy air in your home. By following these simple steps, you'll be able to change your furnace filter with ease and keep your HVAC system running smoothly.
