When choosing an AC unit, you should have a basic understanding of how air conditioners work. No matter what type of AC you purchase, they both take in gas, convert to liquid and then convert it back to gas again. The unit uses chemicals called refrigerants. Window units funnel this air out of the window and simply expunges hot air out of the way.
Window air condition units are stored outside of your living space, which is a great way to reduce clutter. They are also energy efficient, which means you get more cooling power per BTU. Window air conditions can also be installed through the wall which doesn’t really need an actual window space. Purchasing one is a great way of reducing your energy bills in warmer months yet efficiently cooling your home.
If you want to beat the heat and avoid your energy bills, skyrocketing, look no further!
