Window AC / September 4, 2018 / Jacqueline Bizier.
One sees a similar box for a wall air conditioner. Naturally people assume they are the same. But they arent and this article will explain why. The two types share some characteristics. Both span the dividing line from inside to outside allowing all components to be housed in a single box. Therefore both utilize both inside and outside air to perform. Both are designed to condition a single room. But there are differences. Windows are thin and the sleeve for a window unit is designed to take advantage of this. It sits on the window sill with the window closed onto the case to seal the top.
A window air conditioner in my opinion is a last resort for air conditioning your house or building. There are many down sides to window air conditioning units. There are two good things that window air conditioners have going for them. They are very inexpensive when it comes to cost per BTU of cooling. They also install very quickly and easily. That is where the good part of them ends. Window air conditioners are security risks. If a thief wants to get into your house the thin sheet metal box that holds the unit in the window can easily be pulled apart to get in through the window.
If there is no central hot air heating then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed then do not force the issue and go another option. Ductless split type air conditioning may be your best option.
Window units of today are very quiet and their efficiency has improved a lot also. In fact these units are so quiet that you can hardly even hear them operating. Window air conditioners have the same components as a central air conditioner but they are all installed in small cabinet. The biggest and most important difference is that they dont have to cooling capacity of central units. But they also dont cost as much to operate either. If you only want to cool one or two rooms then window air conditioners are a perfect choice. However if you want to cool your entire home a central air conditioner is the best alternative.
