How to Change a Furnace Filter

Maintaining your HVAC system is essential for keeping your home comfortable and efficient, and one of the simplest ways to do this is by regularly changing your furnace filter. A clean filter not only improves indoor air quality but also enhances your system’s efficiency and lifespan.

In this blog, we’ll guide you through the process of changing a furnace filter and discuss why it’s a crucial part of furnace maintenance.

Why is Changing Your Furnace Filter Important?

Replacing your furnace filter is one of the easiest ways to maintain a healthy and efficient home. A dirty filter restricts airflow, forcing your HVAC system to work harder and increasing energy costs. Over time, it can also allow dust, allergens, and other pollutants to circulate in your indoor air. Regular filter changes ensure optimal airflow, protect your system, and improve your home’s air quality.

How Often Should You Change Your Furnace Filter?

The frequency of filter changes depends on factors like filter type, HVAC usage, and whether you have pets or allergies. Generally, it’s recommended to check your filter every 30 days and replace it every 1-3 months. High-efficiency filters may last longer, but it’s always best to consult your HVAC system’s manual for specific recommendations.

How to Change Your Furnace Filter: Step-by-Step Guide

Changing your furnace filter is a straightforward task that requires just a few minutes. Follow these simple steps:

Turn Off the Furnace

Before you begin, turn off your furnace to ensure safety and prevent the system from running while the filter is removed.

Locate the Filter Compartment

Furnace filters are usually located in the blower compartment or behind a removable panel near the furnace’s intake.

Remove the Old Filter

Carefully slide out the old filter. Take note of the arrow indicating airflow direction, as you’ll need this for the new filter.

Inspect and Measure

Check the old filter for dust and debris buildup to gauge how often it needs replacing. If you’re unsure of the size, measure the filter or check the dimensions printed on the frame.

Insert the New Filter

Slide the new filter into the compartment, ensuring the airflow arrow matches the direction of airflow in your furnace.

Secure the Filter and Turn On the Furnace

Close the filter compartment, turn your furnace back on, and enjoy improved air quality and efficiency.
