However, it’s important to make sure that these units are properly sealed to maximize their efficiency and prevent air leaks. In this article, we will provide you with a step-by-step guide on how to seal through the wall air conditioner.
Tools and Materials
Before you start, gather the following tools and materials:

– Screwdriver
– Tape measure
– Utility knife
– Silicone caulk
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.
Step 3: Apply Weatherstripping
Start by applying weatherstripping to the sides and top of the air conditioner. Cut the weatherstripping to the appropriate length and attach it using a caulk gun. This will create a tight seal and prevent air leakage.
Step 4: Seal the Gaps
Using silicone caulk, seal any gaps or cracks around the air conditioner. Apply the caulk in a continuous bead along the edges of the unit, ensuring a complete seal. Use a utility knife to smooth out the caulk and remove any excess.
Step 5: Check for Leaks
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.
Step 7: Regular Maintenance
Regularly check the seal around your through the wall air conditioner to ensure it remains in good condition. Replace any weatherstripping or caulk that has deteriorated over time.
