Window AC Installation Guide

In order for your AC unit to perform at its peak, proper installation is in order. Otherwise, its performance and your satisfaction will be affected. While it’s true that there are several air conditioner brands already on the market, and each model comes with its own peculiarities, there are some installation steps that are universal.

What you’re going to need

• A free window
• A nearby plug
• Your new AC unit

Installation Steps

1. Completely open up your window. Open the bottom of the window and remove the window screens, if you have any. Once that’s taken care of, take a vacuum and clean the sills and channels.
2. Matching Extensions. Several AC models come with sliding extensions, which will play a major role in the installation as you’ll need them to fill the remaining open space. Depending on what type of model you’ve got, the extensions, might, or not, be already attached to it. If they’re not attached, it is advised to prepare them before placing air conditioning unit in the window.
3. Upgrade if Necessary. Some types sit directly on the window sill, while others rest on brackets that need to be attached to the sill before they can function. Depending on your model, there might be a slight difference in how you attach the brackets, so, it’s best to consult the instruction manual.
4. After the mounting brackets have been securely installed, raise the AC up towards the window, carefully put it through the opening onto the brackets, and lock it in place. When you’re sure it’s secure, and you can safely let go without the appliance falling down, lower the window and make sure it connects with the channel found on top of the unit. The channel should be flat completely flat against the sash. Once the unit’s safety is taken care of, slide the extensions to fill the remaining space.
5. Seal Everything. After everything is in place, secure it. The easiest way to do it is to use foam and caulk – the foam on the inside and the caulk on the outside. When the foam is dry and fixed, plug it in and let it work.

How To Clean A Window AC

To maintain your health in good shape, you have to regularly clean out your AC unit, no matter what type it is. Even more, not only the filters require your attention, as the unit, too, needs cleaning. While it might seem a difficult task to tackle, it is, in fact, quite easy.

Filter Cleaning

Step 1. Turn it off and unplug it for increased safety. Depending on how the filters are placed, you’ll have to either remove the front panel or slide them out.

Step 2. Check the filter and determine how dirty it is. If it’s just a little dirty, you can safely let the water run over it. However, if it is packed with dirt or grime, make sure to vacuum it up first, as it will transform into a hard-to-clean mud-like paste if it gets in contact with water.

Step 3. Once the filter is clean and free from any type of dirt, let it dry. You can tap it with a paper towel if there’s water excess, but it’s best to let it air dry completely before placing it back.

In-depth Cleaning

Before the summer begins, or right after it has ended, it is best to thoroughly clean your AC unit. This procedure will not only increase the unit’s life span, but it will also help you avoid any lungs-related diseases, as well as airborne bacteria that, otherwise, might sneak into your house.

Step 1. Unplug the unit and take it off from its window stand. If it’s too heavy, ask for help.

Step 2. Remove its entire casing, and remove any type of dirt that might have accumulated inside. This might include dust, as well as crumbled dead leaves (if you’ve left the unit outside during autumn and winter).

Step 3. Take a fin comb, or any type of soft-bristled brush, and clean the aluminum fins from your unit. The same procedure can be done by vacuuming the fins for a faster, and dust-free experience.

Step 4. Use a cleaning spray and clean the front panel, until there is no more dirt. Also, don’t forget the window fins, and the case. Scrub the dirt away with a soft brush, and repeat the action if the dirt is too stubborn and refuses to come off. After the dirt is gone, rinse with water and let all the pieces air dry completely before reassembling it.
