Default How do I create an opening for a wall A/C unit?

ups.com...
I want to install a small wall A/C unit in a bedroom of my condo. The
other side of the wall I will install the unit in is a storage room
with no drywall. The studs are spaced 16" apart and the A/C unit is
17-18" wide. I am handy with saws, etc. I just don't know how to
create the opening without compromising the strength of the wall. Are
there any tutorials or pictures on how this should look? Thanks.


This is a fairly simple job. If I read the thread correctly, the opposite
side of the wall in open studs, making it easier to work around.

You have to make a box to hold the AC and the studs. One stud has to be cut
so you have to put a horizontal piece on the top and the bottom of the
opening. They can be tied into the studs on either side and supported with
stringers. Take a look at a book that shows framing around a window and you
want to make a similar setup.

Mount the AC level and you should have no problems with water dripping. You
said you will run tubing, but you really don't want to do that for two
reasons:
1. If you drill a hole in the bottom of the pan, you may hit the coil and
ruin the Ac to trash. It happens often.
2. The fan is designed to take the condensate and sling the water against
the heated coil. This evaporates the water and helps cool the coil for
better efficiency.

You may want to consider putting a small fan in the storage room to help
blow out the hot air and bring in cooler air.

I see some negatives posted by others about this setup, but it will work.
My office at work is inside the manufacturing plant and the AC vents into
it. It is also a very hot plant as we use steam for our process. The AC
still works though. In the same building, there are a few other business
that have similar setups with much larger units.

It will be easy enough to remove the AC and drywall over the opening later.
Some paint and it will be invisible.
