DIY: Changing Your AC Filter


Air conditioning units are a staple in most homes, especially during the hot summer months. However, to ensure they function optimally, regular maintenance is necessary. One of the most straightforward maintenance tasks you can perform yourself is changing the AC filter. Here's a step-by-step guide on how to do it.

Why Change Your AC Filter?

The AC filter's primary function is to filter out dust, allergens, and other particles from the air before it circulates in your home. Over time, these particles accumulate, causing the filter to become dirty and less efficient. This not only affects the quality of air in your home but also puts a strain on your AC unit, leading to potential damage and increased energy consumption.

When to Change Your AC Filter?

The frequency of changing your AC filter depends on several factors, including the type of filter, the air quality in your area, and whether you have pets. However, a good rule of thumb is to check your filter every month and replace it at least every three months.

How to Change Your AC Filter?

Here are the steps to change your AC filter:

  1. Turn Off Your AC Unit: Always start by turning off your AC unit to ensure safety.
  2. Locate the Filter: The filter is typically located in the return air duct or blower compartment.
  3. Remove the Old Filter: Slide the old filter out. Be careful not to spill any dust or debris.
  4. Check the Filter Size: Check the size printed on the side of the filter. You'll need this information when purchasing a new one.
  5. Insert the New Filter: Slide the new filter into place, making sure it's facing the right direction. The filter's edge should have an arrow showing the correct airflow direction.
  6. Turn the AC Unit Back On: Once the new filter is securely in place, turn your AC unit back on.

Remember, regular maintenance of your AC unit, including changing the filter, can save you money in the long run by preventing costly repairs and reducing energy consumption. Plus, it ensures a healthier and more comfortable environment in your home.
