Window AC / August 26, 2018 / Denise Brisette
The most commonly used air conditioners are window air conditioners. This is due mostly to the fact that they are the cheapest alternative when it comes to cooling our homes. But there are other reasons also. For example they install in a window out of the way. Install it and forget it. These units are also available with electric heat options. Window air conditioners were once so noisy that they were nicknamed window bangers. This term was very accurate and well deserved. However todays window air conditioners are very different from the ones many of us learned to hate.
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.
If you live in a college dorm studio apartment or a one-to-two bedroom apartment a window air conditioner is probably your best bet for keeping cool during the summer months. Unlike a central air conditioner a window unit can cost under $200 and will do an excellent job keeping your place cool during the dog days of summer. A window air conditioner - as the name suggests - sits on your window in a semi-permanent installation. This type of unit is designed to work straight out of the box and requires minimal hassle when installing to the window. Basically you attach the unit to your windowsill and then close the window down on top of it.
