Window AC / September 16, 2018 / Denise Brisette.
So what you should do? The best thing to do is to check out the sound levels on your window unit before you make your purchase. All air conditioners come with labels specifying the decibels generated by the unit. A high number means a loud machine. For example a unit with a rating of 50 Decibels is 10 times louder than one rated 40 Decibels. The smartest thing to do is to go to a big box store like Target or Walmart and listen to an air conditioner before you buy it. Even if you are looking at a different brand it is important to get a sense of how loud the Decibel ratings are for you. You can do this best by listening to different ac units running.
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.
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.
Window units of today are very quiet and their efficiency has improved a lot also. In fact these units are so quiet that you can hardly even hear them operating. Window air conditioners have the same components as a central air conditioner but they are all installed in small cabinet. The biggest and most important difference is that they dont have to cooling capacity of central units. But they also dont cost as much to operate either. If you only want to cool one or two rooms then window air conditioners are a perfect choice. However if you want to cool your entire home a central air conditioner is the best alternative.
