Window Air Conditioners: How To Install

If you’ve recently invested in a window air conditioner, chances are you’re dealing with a warm home. The good news is that your air conditioner will work wonders when it comes to bringing down the temperature and cooling your house or apartment. However, to truly work effectively, a window air conditioner needs to be installed correctly.

Follow these simple steps to install your window air conditioner and get your home feeling cool and refreshing as soon as possible. Say goodbye to uncomfortable heat in your home. With a window air conditioner, cooling down a room only takes minutes.

Gather Your Installation Tools

Before you start the installation process, you’ll want to collect all the necessary tools and materials you’ll need to properly install your window air conditioner. Some useful tools will include a drill and drill bits, a level, a utility knife, foam weather stripping, wood screws, and sheet-metal screws.

In addition to these tools, you’ll also need to purchase a mount for your window air conditioner. Because the back-end of your air conditioner will be hanging out of your window, a mount is essential to ensuring a steady hold and properly-tilted balance.

Window air conditioner mounts, otherwise known as window air conditioner brackets, should be purchased according to their length and weight support. Mounts come in a variety of sizes and models, so it’s always a good idea to shop around until you find one that can best support the size and shape of your window air conditioner.

Install the Air Conditioner Mount

Before you can install your window air conditioner, you have to install your mount. Your bracket can be installed by using either wood or sheet-metal screws. You’ll want to make sure that the bracket is slightly angled so that the air conditioner will drip water towards the outside of your building when in use.

Secure the Window Air Conditioner

Next, you should center the window air conditioner on the bracket and shut the window pane down onto its top to hold the appliance in place. This will also help you make sure the air conditioner is safe and stable as you work to screw it into place.

Extend the Air Conditioner’s Accordion Panels

Extend the accordion panels from each side of the air conditioner until they reach the window frame’s end. From there, the accordion panels can be screwed into place. In deciding where to place the screws, many accordion panels will have screw holes. If your accordion panels don’t have screw holes, look for a place where the panel overlaps the window pane’s lip.

If there’s any gapping between the accordion panels and the window pane, use foam weather stripping to fill in the space. You want to create as tight a seal as you can between the outdoors and indoors, as you don’t want any of the warm air from the outdoors moving into the home. You also don’t want any of the cool air that the air conditioner will be putting out to escape out of the window.

Power Up the Air Conditioner

Once your bracket is installed, your accordion panels screwed into place, and your windowpane holding down the main appliance, you can congratulate yourself. You’ve just installed a window air conditioner!

As for what’s next? Plug your air conditioner into a wall outlet and power it up. Your window air conditioner should then begin immediately blowing out cold air.

Extra Window Air Conditioner Tips

Window air conditioners are not one-size-fits-all when it comes to cooling different-sized rooms. For this reason, be sure that you check out how much square footage an air conditioner promises to cool before making your purchase. Larger rooms will require larger appliances, while with smaller rooms you can probably get away with purchasing a more affordable mini-unit.

What Safety Precautions to Consider

Last but not least, you should always take care to monitor your window air conditioner unit when it’s running. While it’s unlikely that anything hazardous will occur, because the appliance is connected to electricity, there’s always the risk of sparking or fire.

That being said, you should never leave a window air conditioner unit running when you’re not at home to supervise it. Instead, save the cool air for when you’re home and ready to relax.
