Window AC / September 6, 2018 / Marphisa Babin
A wall with simple sheet type siding may be only 6 inches thick whereas a brick or stone wall can be much thicker. So wall air conditioner sleeves have ventilation louvers only in the back to avoid louvers being covered by the wall edges. This limits the amount of ventilation space available in turn limiting how powerful the unit can be. Wall air conditioners generally dont get much over 14000 BTU depending on the brand. So are they interchangeable? This question usually arises when someone needs a lot of cooling power in a room without suitable windows for a window unit.
To help make that decision more clear I will explore some of the positives and negatives of the two major options. Ductless split type units are also becoming more of an option. I will do another article on that option. To include that in this article would just be more confusing. So for now we will just look at window air conditioners and central air conditioning. Central air conditioning is the best way to go if you already have a central hot air heating system already installed in your house or building. The advantage that you have is that you already have the air handler or blower part already installed.
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.
