Seal Gaps Around Unit
Gaps around your window air conditioner let bugs inside. Sealing these openings stops insects from entering your home.
Use simple materials to close spaces and keep your room bug-free. This also improves your air conditioner’s efficiency.
Use Weatherstripping
Weatherstripping is a flexible strip that fills gaps around the air conditioner. It blocks bugs and air leaks.
Apply weatherstripping on the sides and top of the unit. Press it firmly to hold it in place and seal openings.
- Choose foam or rubber weatherstripping
- Clean the surface before applying
- Cut strips to fit each gap size
- Press strips firmly for a tight seal
Apply Foam Sealant
Foam sealant expands to fill uneven spaces around the air conditioner. It creates a solid barrier against bugs.
Use foam sealant for larger gaps or cracks. Apply it carefully, as it expands and hardens quickly.
- Wear gloves before applying foam
- Shake the can well for even spray
- Fill gaps slowly to avoid overflow
- Allow foam to dry fully before trimming
