Window support for window A/C

I have 2 major challenges to install a small one-room A/C in the bedroom our 50+ year old house. First, the window we want to install the unit in has an indoor sill, but not an outdoor one. What is a quickest and inexpensive material and method to install an outdoor sill or equivalent for A/C support? Second, the window slides left to right instead of up and down. What is the quickest and inexpensive method and material to seal the open gap that will be above the A/C when installed? If you could respond with advice before we melt, it would greatly be appreciated....

Thanks in advance,

You can purchase kits for air conditioner units that need to be supported on the outside. They are basically like an "L" (flipped upside down) that has an adjustable foot (usually a threaded rod with a padded end) that rests against the house.

As far as filling in the hole is concerned, I assume your a/c has a lip inside- if it doesn't, it probably came with the a/c in the box (this piece usually rests on the window sash when you stick the window in the hole.) It would be pretty simple to cut out a piece of plywood that would cover the opening from the inside, so that this lip on your a/c would rest on the bottom edge of the plywood. A few temporary screws around the edge would hold it in place. Or, if you prefer Red Green's methods, use duct tape.

Another alternative to consider, since you have a slider window, is to install a piece of plywood (or two) that would equal the thickness of your sash (the one you had to slide out of the way to put in the a/c). you can cut it the exact size to fit into where the window was when it was closed. Then where it meets the slider sash, you can either tape it, or sandwich another couple pieces of plywood on each side and screw them together to lock the plywood in place on that side.

Plexiglass will work as well and you won't lose any light.
