Top Ten List for Installing a Window Air ConditionerTop Ten List for Installing a Window Air Conditioner

1.) Make sure you have the right type of window needed to accommodate the unit. Is it a double hung window? If your window slides from side to side you need to look at a slider casement type.

2.) Measure the width and height of your available space to install the unit. There is nothing worse than installing that air conditioner on a simmering hot day only to find out that it doesn't fit your space.

3.) to insure you have the right Btuh size, use this simple formula; take the total square footage of the area you want to cool and multiply that number by 30. You will need 30 Btuh's per square foot to cool your area and remember BIIGER IS NOT BETTER!

4.) Pick a window away from direct sunlight, air conditioners installed within a shady area can run up to 10% more efficiently.

5.) Remember that once the window air conditioner is installed it makes it more difficult to clean your window, clean it first before you install.

6.) Make sure that you have the correct power requirements, some units use standard 115 volt service while others use 230/208 voltage.

7.) You will need a three prong outlet, should have a dedicated circuit and avoid using extension cords as they are not recommended.

8.) Some window air conditioners can be pretty heavy, don't be afraid to ask for help.

9.) Read and follow manufacturers directions for installation and use.

10.) Window air conditioners should be installed with a slight pitch towards the back to prevent condensate from leaking into the room and make sure you fill the gap between the window frame and sash with foam that is usually provided which keeps hot air out and cool air in.
