Window air conditioners are the most common style of A/C, but – like everything else in appliances – they’re by no means standard.
Depending on your home, you might purchase a casement air conditioner or a wall air conditioner instead.
Casement Air Conditioners
Casement air conditioners (also known as slider casement air conditioners) are very similar to window units, but they’re designed for framed windows with a sliding sash or metal casement. Casement air conditioners are tall and thin as opposed to traditional window units, which are short and wide.
In general, casement air conditioners cost more than traditional window units and offer less selection.
Wall Air Conditioners
Wall air conditioners, you guessed it, go into a wall cutout. Air and moisture vent through their back, unlike window and casement window units, which exhaust air and moisture out both the sides and the back.
Window air conditioners are NOT appropriate for use in a wall application, as the compressor could burn out from improper ventilation and moisture build-up could cause mold in the walls.
Wall air conditioners also are generally more expensive than window units, as they are more of a specialty product.
But if you don’t like the look of a air conditioner hanging out of your window or if you dislike reinstalling your window unit every year, getting a wall unit cut in to your house could be the answer.
