| 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. 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. |
