Window Air Conditioner Installation, A Step By Step Guide
With this window air conditioner installation guide, you can install your unit
with confidence. A properly installed unit will operate safer and quieter. We will look at installing
the unit in a standard double hung window. The same basic procedure can be adapted for installing in a
casement window. Some basic tools such as screwdrivers, tape measure, level, and a small adjustable
wrench are required.
Before you install your air conditioner, you should ensure that you have the
proper unit. Ensure that the unit has the required cooling capacity in BTU/HR. You must also ensure that
it has the proper electrical characteristics such as the voltage and the amperage as well as the
frequency. This is usually accomplished by matching the electrical plug on the unit with the receptacle
that you intend to use.
Next, you should make sure that you have the proper unit for the type of window
you have such as casement/sliding windows or double hung windows. Special units are required for
casement/sliding windows and not all manufacturers make them.
Now that you have the proper unit, you must find the proper location. There
are several things to consider. First of all, you should find a window with an electrical receptacle
close enough so that the cord from your unit can plug directly into the receptacle. (It is not
recommended to use an extension cord with a window air conditioner because it could pose a fire hazard.)
Next, you should ensure that the flow of outside air to the condenser coil will not be obstructed by
things such as fences, bushes, etc. If possible, you should install the unit in a window that is located
near the center of the room. This will provide for improved air circulation in the room and potential
The next step in your window air conditioner installation is to measure and
mark the center of the window. You should measure the width of the window and divide that number by two.
Then place a mark on the window sill at the midpoint. You should do the same thing with the air
You should remove the air conditioner from its' case. This is typically done by
removing the front grille and then removing a couple of screws that hold the unit in the case. Then, the
unit can be slid out of the case.
At this point, you should install the curtains/frame to the case if the unit
did not come with them already assembled. Some manufacturers send these parts as an installation
