AC window units and sliders

Theodora | Posted in Energy, Heating & Insulation on July 13, 2004 07:07am

Hi. I have sliding casement windows in my rental. Is it impossible to use one of the AC units designed for a double hung in this type of window, or must I get one specifically for sliders? And how do you deal with the open space above the unit when you have sliders? I just intend to deal with the bedroom, not the whole house. It’s 89 degrees in this house at nine at night. Aack. Thanks in advance.

    T, you gonna put this in yurself??? and let's assume you have an aluminium slider....

    Set the AC unit and slide the window closed to the unit... But 1st put foam pipe insulation (the kind the slips over pipe) on the frame and jamb portions of the window that are going to come in contact with the unit's can before you set the unit. Oh yes, one more thing... Put something inside of the jamb as a filler (wood will work) where the bottom of the unit is going to rest... Try not to set the unit directly on the jamb. let it res on the filler... If you sandwich a piece of pipe insulation in there under the unit it will help isolate the noise and dampen vibrations...

    Put a SMALL sheet metal screws thru the jamb and into the window frame, top and bottom, left and right, to hold the window closed. Make sure you miss the glass... A wedged in filler stick will work if you can't do screws

    For a filler piece you can use a piece of painted plywood screwed to the jamb and window frame.... More pipe insulation to close up the air gap between the WF and plywood... Slip it on or make long slices of it as you see fit...

    If you use some really cheap, real cheap, latex caulk like that 70 cent stuff from Wally World between the jamb and ply as glazing it will give you a seal that will be easy to remove and clean up if you have to at a latter date...

    Plan "B" would be to use plexiglass instead of ply... More weather resistant and will light pass thru.. Look better too.... Use a poly caulk where the panel (same for the ply) meets the unit's can... The exposed cheap stuff will fail in no time...

    The top of the unit should have a piece of angle metal fastened to it that you can fasten yur panel to. If not, add one. BE CARFUL that you don't hit anything vital inside the can when you do this... Short screws please.. Use yur caulk as a gasket between the angle and the can.... 

    Should be good to go..

          Well, I went out and got some stuff, and I'm going to give it a try. Don't make fun of my cheapo AC unit. It's what I could afford, what I could actually lift, and what would fit into a 22 inch window. I'm feeling pretty optimistic, but first I have to read the saw manual. That's one I gave the ex five years ago for Christmas that he never had anything to do with, so I took it when I ran away from home.

            Way to go T!!!

            Is the window vynal??? If so could you post a pic of the track, frame and jamb please... and one of the unit out of the box...

            The can (cover) for the AC should easily come off (remove a few screw, slide the cover off) and that would make life so much easier for you... the can won't weight but a couple of pounds... No slugging all that poundage if you don't have to.

            You may have to alter the plan a bit and have the window sill carry the weight of the AC...

            Is there a rack that came with your unit that mounts out side of the window to hold the unit up???

            Another way that might work...

            Cut yourself a peice of 3/4'' plywood the size of your window opening keeping in mind on some how to fasten it to the window frame.

            Paint the plywood a desired color.

            Measure your A/C unit and cut a rectagular hole in the plywood so you can push the unit into it.

            Couple of screws through the fins of the unit into your pretty lookin plywood.

            Plug it in.

            Voila!

        That's what I was thinking about trying last night!

        The ACs made for sliders are just not in my budget. IMERC, I'll get started today and see how things go. Yes, I'm doing it myself.

    There are window units made to fit the vertical as found in slider windows. They require a verical filler above the unit after setting the unit on the sill.  Much in the same way that DH window units require a filler on the left and right,

    Since slider style A/C's are less common you can expect to pay more $$ than a regular window type.  Check out your local appliance dealerships.

    You might consider converting a window unit to a thru-the-wall install.  A little time and effort plus less $$/unit will allow theinstallation of a bigger BTU unit and not lose the the proposed window's integrity.   Easier to close off the T-T-W in the winter.  Less chance of air or water infiltration.
