Transcript:How to Install a Window Air Conditioner

Hey, I'm Alex Nice from About.com. Summers back, and its going to get hot, it's time to install that window AC unit.

Installation Supplies

So let me show you what you are going to need: a Phillips-head screwdriver, insulated foam, and a tape measure.

Attach Cover Brackets

We are going to measure the length of the window to make sure it fits the window. Make sure you move any curtains or anything else that could be in the way. Some AC units come with these little cover brackets that you have to install yourself. You have to pull them out. There are metal clips on the side. Slide them in to the metal clips. This is we are going to have to screw in.

Put Foam in Windowsill

You open up your window and you take the foam and put it on your windowsill you can also take another foam and put it on the top of your unit where the window closes on to it. The side covers and the foam will keep that cold air from escaping and save on your electric bill.

Lift AC Unit Correctly

Be careful when lifting your AC unit, some off them are heavy. Lift slowly and carefully. I can't emphasize this enough. Lifting is a common cause of back injury. Stand yourself in front of your AC unit place your hands on either side of the bottom of the unit. Make sure your legs are about shoulder width apart. Bend your knees, keeping your back straight, Lifting with your legs and not your back.

Balance AC Unit in Window

Now for the tricky part: using one hand to keep the unit balanced, use the other to slowly close the window into the top bracket. You don't want to lose your balance and drop that AC unit crashing into the sidewalk below. That's what's going to hold your AC unit in place.

Plug-In AC Unit

Pull the slide cover out on either side until your window is completely covered. Now all we have to do is plug it in and let the cool air flow. Get yourself a glass of water, maybe check out more homeowner tips at About.com. Later.
