Comments on How to Install an Air Conditioner

You may want to add that a window a/c needs a support bracket or shelf on the outside. That is the heaviest end. Additionally angle the a/c down slightly so that moisture drains to the outside.

Excellent tips - especially for this time of year!

how to compute size and no. of diffusers from a 500mm x 300mm air duct supply

Very fine article. Just one comment: Most window units are meant to be slid out of their housings before being installed. This is to allow the installer to mount only the lightweight housing in the window first, and then just slide the heavy unit in.

I don’t think I’ve ever seen a window screen that you couldn’t remove, but if that’s the case with your window you still do have a couple of options.Free standing air conditioners are available that are essentially window air conditioners on wheels. You just plug them in and they can be moved from room to room. Check at home or hardware store or even a department store.You could also get a freestanding dehumidifier that would take the moisture out of the air and combine it with a fan to move the air.

HELP! My room is an oven in the warm months, but my window has a screen built in, which makes installing a much-needed air-conditioner seem impossible. Suggestions and non-destructive solutions would be most welcome! Thanks. Glen - Toronto, ON

for my side to side sindgle hung window I built a platform for the a.c. unit to sit on and secured it to the window sill (the platform sticks out to the outside). I removed the sliding window and screen. Cut out 1/4 inch plywood the same size as the window that was removed. Cut out a square in the plywood for the ac unit to fit in and attached the plywood to where he window use to be. Slid in the ac unit on the platform and plugged it in. Voila, sunshine on the left and ac unit on the right! Took about 30 minutes.

How do you install in a window that opens side to side, not up/down? Thanks!!

Window air conditioners (and all air conditioners really) are designed with the knowledge that they will be outside. They are designed to stand up to the elements. Most units are designed to be installed with a slight outward tilt for drainage (the manual usually addresses this). Some even have this tilt designed into the case. Covering the unit may cause airflow blockage, which can hinder performance and even damage the unit.

I've just installed a window air conditioner. My wife is concerned about weather damage to the outside portion of the a/c and that rain may enter the a/c case and exit toward the front into the room. Should I cover the outside portion of the A/C with something to prevent the water problem, if there are any.
