I just bought a used Window A/C unit for my son. I am looking for
help in the installation. I have confirmed that the window opening is
large enough. Are there any kits ? Or do I have to build one. I need
some ideas before I start cutting or hammering.
You should not have to buy anything. Is there a frame around the front half
with sides that expand? You set the unit in the window opening, close the
window down and screw the sides into it to keep everything together. Close
any opening between the windows with a piece of foam so bugs and bats cannot
If that is not your situation, please describe what you have.
Thanks Ed. The unit is a used unit and not very well looked after.
The expanding sides were all broken and had to be removed. I had the
unit on a bench and plugged in this afternoon. Found some noise
coming from the compressor that goes away if the backend of the unit
is raised to about 20 degrees above normal. Otherwise the unit cools
- well from what I could feel with my hands.
Leave the frames in place even if the panels are broken. Cut pieces of
masonite or plywood to size to fill the openings.
Could be something loose inside if the noise goes away when tilted. Perhaps
the fan is hitting something. Only way to tell is to remove the outer
casing. I hope you didn't pay too much for it. Brand new bedroom sized ACs
can be bought for less than $100.

Fix whatever's making that noise before installing, so the A/C can be
installed with the back tilted slightly *down*. Installed flat, or
worse with back tilted up, and you'll have water in the house.
As for the missing side panels, I believe I've seen generic
replacement kits at the Despot, Wal-Wart and their ilk. Fome-Cor or
rigid styrofoam sheet also work, as do Edwin's suggestions of masonite
(aka hardboard) or plywood. Depending on the install and what I've got
lying around, I often use one of these in addition to the side panels
as they usually don't provide a good seal.
Also, if air conditioner is large, it may need angle bracing from
Personally, I am always careful to make sure AC is securely mounted in
the window (even if it requires some creative extra support),
especially when the window is above the first floor level and when the
unit is a 20K+ BTU monster. The idea of someone accidentally forcing
open the window or shifting the ac so that it falls just scares the
heck of out of me...
Thanks all for your input. Here is an update:
I decided not to take a chance on the old unit and bought a brand new
one - a 5600BTU that was on sale. I had it installed without too much
of a problem. However, when I fired the unit up, I realized that the
unit may be too small for the apartment. I accounted for the size of
the living room - forgeting that the kichen, bathroom and bedroom are
all part of the apartment. I went back to the store and they've
ordered an 8000 BTU that is on back order. I will make the exchange
after delivery of the 8000BTU unit next month.
The installation was not as difficult as I thought and your comments
gave me moreconfidence to tackle the job.
What you need to do is get or build a tall stand to put a large floor
fan on that will push the cool air to the other rooms.
That will also result in the 5,600-Btu/hr unit to better heatload the
evaporator coil resulting in more cooling.
Without a circulation fan the 8,000-Btu/hr unit will get the room it is
in too cold and will probably not effectively cool the other rooms.
I have a mere 6,000-Btu/hr room A/C that cools 950 sq ft that includes a
hallway living room, dining room and kitchen.
Even on 90-F plus days with relatively high humidity it will pull the
temp to around 76-F and the humidity to 56% or lower!
