- Close the window gently until it contacts the top of the unit, securing it in place.
Secure the Unit in Place
- Most window A/C units come with side panels that can be extended to fill the gaps on either side of the unit. Pull out these panels and attach them to the window frame using screws or adhesive strips, depending on the model.
- Use a screwdriver or drill to secure the unit to the window frame. This will prevent the unit from shifting or falling out of the window.
- Check that the unit is level using your level tool. If necessary, adjust the support brackets or the position of the unit to ensure it is level.
Seal the Gaps
- To prevent air leaks, use foam insulation strips to seal any gaps between the window frame and the A/C unit.
- Apply the foam insulation around the sides and top of the unit, pressing it firmly into place.
- This step is crucial for maintaining energy efficiency and preventing warm air from entering the room.
Plug in the A/C Unit
- Once the unit is securely installed and sealed, plug it into a nearby electrical outlet.
- If the unit requires a higher voltage outlet (e.g., 220V), ensure you have the appropriate outlet installed before proceeding.
- Turn on the unit and test it to make sure it is functioning properly. Adjust the temperature and fan settings to your desired levels.
