Window air conditioners and wall air conditioners can be closely inter-related. The only difference is that window air conditioners are installed in a window whereas wall air conditioners are installed on a wall. Wall air conditioners are effective for a single room.

Installing a wall air conditioner requires a hole in the exterior wall of the room. It may cause trouble if the wall has pipes or wires running along it. An expert will be able to do the job if the walls are made of concrete or brick as it is not an easy task unless you are experienced and can do the job properly.

The instructions in the manual need to be read properly before doing the job as it has all the details of installing the unit. In case of any queries, you should call the customer help desk and get your job done properly by understanding all the points explained to you by them.

The unit should always be slightly out of level, which allows the condensate to drain without causing any problems. Before plugging, check the voltage. It should not overload the outlet circuit. We should not forget that the cord from the plug point should reach the unit through the hole.

All the above things should be done carefully and properly. You should not try anything if you are not sure what has to be done. It is always advisable to seek the services of a professional air conditioner installation company.
