What Does a Furnace Filter Do?

A furnace filter is an important part of your heating system. It is installed inside the furnace and is designed to trap airborne particles, such as dust, pollen, pet dander, and bacteria, before they’re distributed throughout your home. Not only does this improve air quality, but it also reduces allergy symptoms and can alleviate respiratory issues.

Additionally, your furnace filter plays a crucial role in maintaining the efficiency and longevity of your furnace. A clean filter allows for proper airflow, ensuring your furnace operates at peak performance, consumes less energy, and experiences less wear and tear. The harder your furnace has to work, the more strain your system will experience. This can cause your furnace to break down earlier than it otherwise would.

How Often Should You Change Your Furnace Filter?

Every home, heating system, and type of furnace filter is different, so there is not one universal answer to how often you should change your furnace filter. However, as a general rule of thumb, check your furnace filter every month and assess its condition.

If you notice that the filter is visibly dirty or clogged, it’s time for a replacement, regardless of the amount of time that has passed since the previous change. Factors such as the type of filter you use, the presence of pets, the number of occupants, and local air quality can all influence the frequency of filter changes.

How to Replace Your Furnace Filter

Replacing your furnace filter is a fairly straightforward process that most homeowners choose to do on their own.

Begin the process by turning off your furnace to ensure safety. Locate the filter compartment, which is usually near the return air duct. Note the filter’s size (printed on the frame) before purchasing a replacement.

Remove the old filter and dispose of it. Slide in the new filter, ensuring it’s aligned correctly with the airflow arrow pointing toward the furnace. Secure any clips or latches, and then turn the furnace back on.

Other Furnace Maintenance Tasks

Regular filter changes will contribute to a healthier indoor environment and optimal furnace performance, but there are other steps you can take to maintain your furnace, including:

  • Regular Inspection and Cleaning: Apart from changing the filter, periodically perform a visual inspection of your furnace. Clean any external parts that appear dirty. If any parts look worn, contact a professional for service.
  • Clear Air Vents and Ducts: Ensure that air vents and ducts are free from obstructions. Vacuum and dust these areas to prevent airflow restrictions and maintain consistent heating throughout your home.
  • Lubricate Moving Parts: Some furnace models have motors and bearings that require lubrication. Check your furnace’s user manual to determine if lubrication is needed. Ideally, this should be performed by a professional.
  • Monitor Thermostat Settings: Verify that your thermostat is functioning correctly and is set to the desired temperature. Calibrate or replace it if you notice any inconsistencies.
  • Schedule Maintenance: Many furnace tune-up tasks should only be performed by a professional, both for your safety and the optimal performance of your heating system. Scheduling regular professional maintenance is the best way to ensure your furnace operates at its best.
