How to Change the Filter on a Central Unit

Here are three easy steps on how to change your air conditioner filter when needed.

Step 1: Shut off the system

Health and Safety first so, make sure to cut off the power completely before beginning the replacement process. Also, to prevent dust and debris entering into the unit during the cleaning process the power must be turned off.

Step 2: Remove the old filter

The most simple step, slide the filter out of the slot.

Step 3: Check the condition of the filter

Once the filter has been removed checked the condition of the filter by holding it up to a light and see how dirty and clogged it looks. If every light makes it through the filter it means it needs to be replaced.

Step 4: Insert the new filter

Before entering the new filter make sure it is done correctly by locating the arrow on the filter frame, which indicates what direction the air should flow through the filter. This will always be away from the return air duct and towards the air handler mechanism. When the filter is placed back into its intended spot, point  the arrow  away from the return  and towards  the air handler.
