I looked all over the Internet both YouTube and Google Images and I
couldn't find anything on installing a window AC the way I'm going to do it
last year I just set that AC in the window and extended the little plastic
sides and you know that works but it's a real easy way for people to break in or
steal your AC and it's not very it doesn't keep a lot of the hot air out
and cold air in so I'm going to use a piece of plywood and screw it on there's
you know somewhat or semi-permanent where I can remove it every fall and be
able to silicone around it keep bugs out and and hot air from coming in so I want
to show you how to do that since it's fairly simple but I didn't see anything
else on the internet describing this so what the heck here we go
all right first thing I'm going to do is measure the opening
okay I got it the cut let me tell you what this is by the way it's 3/4 treated
plywood if I hadn't mentioned that there is a gap at the bottom but this room was
the carport at one time it's now our sunroom and the carport was slanted away
from the house so rainwater would drain so there is a slight gap at the bottom
of that but what I'm concerned about is the sides and the top being square and
I'm going to probably put some trim around the inside edge of this the
reason is that that will help to hold the plywood up against the window frame
and it'll all look good now I've got to measure the air conditioner and cut that
hole in that plywood and now I'm going to show you how to do a plunge cut for
those that know how to do it this is nothing new but I'm sure there are
people that just don't realize you can start a cut in the middle of the piece
of plywood by using the plunge method it's a little bit dangerous but if
you're careful you can do it and so that's what I'm gonna do next is measure
that their air conditioner okay I got my hole marked for the air conditioner
start teen by eighteen and a half now I'm going to show you how to do a plunge
cut you pull this has a guard on the bottom you have to hold that up as you
as you're doing this you got to keep your hands somewhere safe this is kind
of hard to do it's a little unsafe so you know if you decide to try this I'm
not responsible for any lost fingers okay here we go
you look real close and you Center this blade on the line you're going to start
and you want to make it go into the wood square you want to lower what you do is
rest the front edge of this circular saw on the wood you line that blade up with
a line you want to cut cut the saw on and then you lower the blade ever so
slowly into the wood and you want to hold on tight and be ready to let go of
the guard on the trigger if you should get hung up or bound up here we go let
me put my glasses down
there's one I got to do all four sides with that type of plunge cut and then
I'm going to get my jigsaw you see with the circular saw since the blade is
rounded the corners are going to have a little left in them and you'll have to
get a jigsaw to finish up these little cuts so all LOB finish these other three
cuts and then I'll show you how to finish it up with a jigsaw I'll show you
that plunge go one more time just so you can get a good idea how to do
we write back with a jigsaw okay once again the reason you can't finish these
corners with a circular saw is because of the curvature of the blade in order
to complete this cut you'd have to go past your lines which would leave for a
very ugly cut on the backside you'd be able to see the criss crossing of the
blades where the cut crosses in order to go past the corner so you stop before
the corner you take you jigsaw and you finish up the corners now I'm going to
mount this in the window with some screws and then I'll put my air
conditioner in I'll show you how to mount the air conditioner where it won't
vibrator people won't be able to break in through it okay here we go
I tend to go overboard with fasteners so uh it's going to take a lot of effort
but I'm going to force myself to only use two screws on the other side these
screws on both sides of this I'm going to have to toenail into the window frame
and behind here the bottom edge there's a inch and a quarter inch flange all the
way across the bottom on the outside and the top here I'm going to go right in to
the bottom edge of the aluminum no I want this to be a really tight seal
to keep bugs out and and cool they're in hot air out okay I got my screws in I I
just couldn't stand it I had to put three in the bottom and the three in the
top I have no willpower when it comes to fasteners that's why I don't drink or do
drugs one beard led to 30 and one joint led to a whole sack all right I'm fixing
to slide that air-conditioner in here okay a little bit of caulking around the
inside and the outside this would be weather tight and then I'll give it
about a week to dry that wood is treated wood and it's still green and wet from
the insect in waterproof treatment they put on it so it'll probably take about a
week to dry out and I'll put a coat of paint on it on the inside and the out
there you have it nobody can steal it or kick it in it's as strong as a window
would be so I hope this helped if anybody was searching for a way to put a
window AC unit and a semi-permanent method where the AC won't get stolen and
you leave yourself open to people trying to crawl in it through the
air-conditioner opening all right I'm going to put this up see you thanks for
