To fill a gap in a window air conditioner, first measure the width of the gap. Cut a piece of cardboard or other material to fit snugly into the gap. Tape the material in place so it does not move.
Next, fill the gap with expanding foam insulation. Apply the foam evenly and allow it to dry completely. Finally, trim away any excess foam with a knife or saw.
- Unplug the window air conditioner unit from the electrical outlet
- Remove the front panel of the air conditioner unit, according to the manufacturer’s instructions
- Inspect the foam seal that is located around the edge of the opening in the window frame
- If the foam seal is damaged, cracked or missing, it will need to be replaced
- Cut a new piece of foam seal to fit snugly inside the window frame opening
- Apply a generous amount of silicone caulk around the edges of the new foam sealant and press it into place firmly
- Replace the front panel on the air conditioner unit and re-install it in the window according to manufacturer’s instructions
