Before buying a standard window air conditioner for your home, you should be prepared to modify your window because the cooling solution is not designed for horizontal-sliding windows. As such, you will need pieces of wood, foam board or plywood, or any other material that you can use to modify your window. Below is a step-by-step procedure of installing the system:

  1. Select the place where you will install your window air conditioner. Make sure that there is a power outlet close to the window.Inspect the window and ensure that there is enough space for the modifications required. Since the air conditioner is not designed for casement slider windows, you will need enough space for a table-like structure to carry the cooling system.
  2. Measure your window air conditioner and use the dimensions to build a strong wooden support for your unit. It should be strong enough to carry the weight of the unit. If the unit falls to the ground or deck, it can break or injure a person.To prevent this from happening, you should make sure that the support is strong and stable. You can reinforce its stability by fixing it to the deck or ground, or through any other means.
  3. With the help of extra hands, lift the air conditioner and place it on the support. The support should carry most of the air conditioner’s weight. Use a spirit level to tilt the unit so that it drains captured moisture through its rear. For maximum efficiency, the ventilation of the unit should be outside the window.
  4. When the unit is in place, you will need to seal the open space above it. You can use wood or foam board. You should select a material that will perfectly fit in the window groove and that cannot be easily broken.Make sure all the gaps and spaces are properly sealed to prevent hot air from find its way back into your house.
  5. Plug in the unit and test it.
