Window AC / August 28, 2018 / Jacqueline Bizier
Another huge improvement in window air conditioners is in their appearance. Older models did not blend in very well with their surroundings. They were usually some shade of brown and looked like there was a box in your window. Window air conditioners today are much less obtrusive and look less like boxes. Corners are rounded and colors are much lighter. This gives them a much sleeker look. As with most things once they have been around for awhile cost become more reasonable and less of an obstacle. A window air conditioner can be purchase for less than two hundred dollars and often not much more than one hundred dollars. Of course this is for smaller units. Costs go up as the cooling capacity of the unit increases.
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.
