Step 1: Measure and Inspect

The first step is to measure the dimensions of your through the wall air conditioner and inspect the area around it. Look for any gaps or cracks that may be present.

Using a tape measure, measure the height and width of the unit. This will help you determine the amount of weatherstripping and caulk you will need.

Step 2: Clean the Area

Before applying any sealant, make sure the area around the air conditioner is clean and free from dust and debris. Use a screwdriver to remove any loose caulking or weatherstripping.

Once you have applied the weatherstripping and caulk, it’s important to check for any remaining leaks. Turn on the air conditioner and feel around the edges for any air escaping. If you detect any leaks, apply additional caulk or weatherstripping as needed.

Step 6: Insulate the Inside

To further improve the efficiency of your through the wall air conditioner, consider insulating the inside of the wall. This can be done by installing foam insulation panels or using insulating spray foam. This will help prevent any air from escaping through the wall.
