Changing a filter in a generic air conditioning system involves a few straightforward steps, regardless of the specific brand or model. Here's a general guide to help you through the process: 1. Turn Off at the Thermostat: Before starting, ensure the system is turned off to prevent any air circulation while you change the filter. 2. Locate the Filter: The filter is typically located at the return air duct at the furnace or inside the air handler unit. It may be behind a grille or access panel. Or install in the return grill in the house. 3. Remove the Old Filter: Open the grille or access panel and carefully slide out the old filter. Take note of the filter's size and the direction of airflow, which is usually indicated by arrows on the filter frame. 4. Select the Correct Replacement Filter: Ensure you have the correct size and type of replacement filter. Filters come in various sizes and thicknesses, so it's important to match the new filter to the old one. 5. Write the date on the filter for easy reference on your next filter change. 6. Install the New Filter: Insert the new filter into the slot, making sure the airflow arrows point in the correct direction, towards the air handler or blower. 7. Secure the Filter: Close the grille or access panel securely to ensure the filter stays in place and the system operates efficiently. 8. Turn the Thermostat Back On: Once the new filter is installed, turn the system back on and check for proper operation. Regularly changing the filter, typically every 1-2 months depending on usage and filter type, helps maintain system efficiency and indoor air quality. A 4 inch thick filter can last as long as 6 months. Don’t Want to Do It Yourself? While changing air filters is a straightforward process, some people prefer to leave it to the professionals.
