Window AC / September 1, 2018 / Babette Arsenault
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.
I have seen many units that are not even screwed fast. If the window air conditioner is just there balancing in the window frame it becomes very inviting for a unexpected guest. The window air conditioner is also very inefficient. These units use more power per BTU of cooling than any other type of air conditioner. If you are a light sleeper than chances are you will not want one of these window shakers. Window air conditioners are one of the loudest forms of air conditioning. The blower for these units is very loud when running. Then add the noise of the compressor and you have enough decibels to keep many people wide awake all night long.
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.
