If you are looking for a reliable step by step guide on how to install a portable air conditioner, then you don’t need to look any further. This guide will help you to install your cooling system quickly, easily, and correctly.

How does a portable air cooling system work? Most portable air conditioners employ refrigerants to cool the spaces in which they are installed. The hot air is then channelled out of the room through a hose. In most cases, the hot air is vented out through the window. Other openings in a room can also be used for this.

Although most portable air conditioners utilize a single hose design, some are based on a dual hose design. For the sake of this guide, we will assume that you want to install a single hose air cooling solution. Furthermore, we will assume that your room has a window.

Step by step guide on how to install a portable air conditioner

  1. Read the installation guide
    A portable air conditioner usually comes with an installation guide. This guide will enable you to understand the specifics of the brand that you have purchased. When you are through, remember to put the guide and other documentations in a safe place.
  2. Select a suitable place for your portable cooling system
    For convenience, you should place your air conditioner near an electrical outlet and a window. Cables can be tripping hazards especially if they are unsecured. You should also ensure that the position you have selected is free from obstructions. Furniture, walls, plants et cetera can obstruct airflow thereby reducing the efficiency of your air conditioner.
  3. Check if the window venting kit is compatible with your window
    Window venting kits are usually designed to fit in most standard windows. In case it does not fit perfectly, then you may need to do some improvisations. The size of the opening of your window will determine whether you should trim or expand your window adaptor kit. You can easily expand the kit by using a piece of plexiglass, plywood, or cardboard.
