Window AC / September 14, 2018 / Aubrette Dumoulin
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.
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.
Why are window air conditioners so loud? Well the reason is simple: because the entire air conditioner - the compressor the condenser and the fans - are all located in one single unit. By contrast with a split ac and a central air conditioner the compressor and condenser are installed outside of your home. That means that in those units the loudest parts arent in your home. With a window unit however the noisiest parts of the unit are inside your home. This can be a minor annoyance. It may mean that you have to turn up the volume on the tv to hear it. But it can also mean sleepless nights if your window air conditioner in your bedroom is deafening.
