Changing your furnace filter is a simple yet essential maintenance task that can improve the efficiency and longevity of your HVAC system. As a leading provider of heating and air conditioning services in Vancouver, Ashton Plumbing, Heating, and Air Conditioning understands the importance of regular filter replacement. In this article, we’ll provide you with a comprehensive guide on how to change your furnace filter effectively.

  • How often should I have my furnace filter? We recommend homeowners change their furnace filters before winter, or during spring if your furnace/central air system has cooling capabilities or a summer switch. This will ensure that clean, filtered air is circulated in your home.
  • Prepare the Necessary Tools: Before you begin, gather the tools and materials you’ll need for the task. This typically includes a new furnace filter compatible with your HVAC system and possibly a screwdriver to remove the filter from the filter tray.
  • Locate the Filter: The furnace filter is typically located near the blower or air handler unit. In most cases, you can find it behind a removable panel on the furnace housing or within the return air duct.

  • 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 to ensure you install the new filter correctly. Take note of the filter size. While there are a few common filter sizes, ensure that your replacement filter is compatible with your furnace.
  • Inspect the Filter Slot: With the filter removed, this this opportunity to remove debris and dust that may have collected near the filter or its housing.
  • Insert the New Filter: Take note of any arrows indicating the airflow of the filter and its correct orientation. Insert the filter and ensure the filter is seated correctly to prevent leaks.

Regular filter replacement not only improves indoor air quality but also helps prevent costly repairs and extends the lifespan of your furnace. If you are interested in an annual free furnace filter replacement for your home, consider joining the Ashton No Problems Plan!
