Window AC / September 1, 2018 / Babette Arsenault
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.
Today window air conditioners are becoming less popular then wall split-systems. And it happens for several reasons. These air conditioning systems are indeed much noisier than split-systems and they significantly reduce the daylight area. But besides some disadvantages window air conditioners have decided advantages. The main advantage is reasonable price. Another important factor is easiness in installation and relatively small amount of Freon in the system. Modern device models provide intensive ventilation and air conditioning and are characterized by economical operation.
Side panels fill the gaps on the sides. These are also very thin so most of the sleeve is uncovered and outside. This allows for placement of ventilation louvers on the sides and top allowing free movement of air. This is the primary difference between the two types. The wide availability of louver space allows the unit to move a lot of air and this means window units can be quite powerful up to 3 tons or 36000 BTU. So window A/Cs can be effective for very large rooms. In contrast a wall air conditioner sleeve is designed for a hole through the wall. Walls vary substantially in thickness.
