Window air conditioning units are definitely convenient. Of course, they do have certain drawbacks that you need to consider. First of all, a window air conditioning unit is only going to work in one room at a time. If you have a house with multiple rooms, and you want air conditioning, you should consider retrofitting your existing duct system to work with a central air conditioner. If you don't have this option, you will need to have an air conditioner in every single room that has a window. This article explains two things you need to do if you are going to try and cool your home using window air conditioning units.
Remove Your Units Every Winter
First of all, you should only install window air conditioning units if you are willing to uninstall them during the winter. This is probably going to be necessary because you're going to want to restore your window to its original insulation during the winter.
Most AC units are actually very easy to install and uninstall. They can be removed within a matter of minutes. In fact, many systems have designs that enable them to be set within a window fixture without even being screwed down or fastened. Instead, the unit rests on the window seal, and then the top, movable sash can close on top of it. This design makes it much easier to take the unit out before winter.
Clean Your Unit Once a Year
This is also important because you will probably want to clean the outside of your AC unit before you reinstall it every year. That is, the outside of the air conditioning unit, where the evaporator is, is a vital part of your system. It is going to get dirty because it sucks in air. So it is very common for dirt, leaves, and all types of grime to get stuck in between the evaporator coils that line the outside. These are the thin, metal fins that are sticking out.
You can clean these using a special coil cleaning solution and a brush. When you brush out the coils, just make sure that you go with the grain of the fins. If you go against the grain, you can bend them and make the problem even worse. So, if you do want to invest in window AC units, you need to take care of them, remove them every winter, and clean them before you reinstall them.
