Window AC / September 9, 2018 / Denise Brisette
If you already have a window air conditioning unit and you have noticed recently that it seems to be louder there are few steps you should take. Check to see if the unit is vibrating on the windowsill. It may need to be re-tightened on its shelf. The side panels might also be loose. Inspect those to see if they need tightening. If the unit seems to be vibrating more than normal consider sliding a piece of wood under the unit to secure it.

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.
The most popular brands of window air conditioners in the US are General Electric LG and Friedrich. You can find these units at various big-box retail stores like Best Buy or Sears as well as at online at merchants like Amazon. The cost of window units varies widely depending primarily on how many BTUs you need. The smallest units can be as well as $180 with the larger units running up to $500. In some climates Summer months can be downright unbearable without an air conditioner. Window A/Cs are less expensive than central air cooling systems and they typically use less energy than whole house systems as well.
