A step-by-step guide that shows readers the correct way to change their AC filters, an essential maintenance task to ensure the efficiency of their units.

Keeping your air conditioning unit in top shape is essential for ensuring it runs efficiently, saves you money on energy bills, and provides clean air for your home. One of the simplest yet most crucial maintenance tasks is regularly changing the AC filter. Not only does this improve air quality, but it also extends the life of your AC unit. Here’s how you can change your AC filter in just five easy steps:

Step 1: Locate Your AC Filter

Your AC filter is typically found in the return air duct or blower compartment before the return air reaches the air handler. In some homes, it might be behind a return vent on a wall or ceiling in a central room of the house. If you’re unsure, check your AC unit’s manual, or look online for specific model guidance.

Step 2: Check the Size and Type of Filter

Before you remove the old filter, make sure you know the correct size to purchase as a replacement. The size is usually printed on the edge of the filter in length x width x height (e.g., 14″ x 25″ x 1″). There are also different types of filters, from disposable fiberglass filters to more permanent, washable ones. Choose the one that best fits your needs and is compatible with your system.

Step 3: Turn Off the AC

Safety first! Always turn off your AC system before attempting to change the filter. This prevents the system from turning on while you are working, which could draw in debris and dust or pose a safety hazard.

Step 4: Remove and Assess the Old Filter

Slide the old filter out along its tracks. Look at the amount of dust and debris accumulated. If it’s coated in dust, it’s definitely time for a change. If it’s been three months or more since the last change, proceed even if the filter doesn’t look very dirty. This can depend on your specific environment and manufacturer recommendations.

Step 5: Insert the New Filter

Slide the new filter into place, making sure that it’s facing the correct direction. Filters are designed to trap particles from one direction, and an arrow on the frame’s edge indicates the proper airflow direction. It should point away from the return air duct and toward the air handler mechanism.

Once the filter is snug in its housing, turn the AC system back on. And just like that, you’ve successfully changed your AC filter!

Conclusion

Changing your AC filter is a quick and necessary task that can prevent a multitude of problems, from inefficient operation and higher energy costs to unnecessary wear on your AC unit. For the well-being of your system and the air you breathe, set a reminder to check your filter every month and replace it as needed. Your lungs and your wallet will thank you!
