How to Mount a Box Air Conditioner in a Sliding Window?

So, I'm currently renting a nice place that has not-near-enough A/C for the layout/size of the house.

Every window is about 600mm from the floor & a slider (from the side, not up & down). I've looked around & all I see are the A/C type which stand on the floor— but you have to have some place for water to leach out through a tube plus the exiting hot air has to also vent out.

Then, I thought of the box type you mount in a hole in the wall & wondered if anybody here had ever modified or created a frame to install one, semi-permanently, to a sliding window?

Thanks everyone.

  • I have mounted one in a double hung wooden window, a similar issue.
    I have seen things like this:

    But I got a sheet of marine 3ply that I cut to the exact gap size, with some foam gap sealer along the edge, plus some aluminium angle to make some cantilever legs for the unit. It looks a bit like this.

    • I mount mine similar to that, but with a wooden frame around it cut to fit the width (less a little, where I use foam to fill the gap) Then also have a right angle bracket on the outside to take the weight. I have seen some mounted further forward to let the window frame take the weight - I suppose depends on design of window frame.

  • Yeah, I had these units when I was in Florida & they were in the same type window— slides up & down….Mine slide in from the side.

    I'm thinking I'd need to build a wooden frame to both hold the A/C + fill the gap above. Also, will need to "block-up" so the unit actually rests on wood on either side of the track (not resting on the thin, metal slider frame). Then, find a way to wedge inside so that the window can't be "jimmied" open from the outside.

    Sigh…why is everything so difficult & convoluted for renters?

    Thanks for those images, appreciated.

    • Offer the landlord $10 a week extra rent if they install aircon?
      Worth a shot.

      • You wouldn't believe the layout of this place. Two front rooms divided by an entryway, with a swing door from the entry into the main kitchen/living area. The only A/C is in here & can't cool the front two rooms unless we place a fan at the open door & then another to try to carry the air to my son's room (furthest away at the front-right). At the other end of the living space is two more bedrooms- again, we try to use fans but really that one, small A/C is simply insufficient. Unfortunately, we moved in during winter so had no idea.

        There are literally NO other exterior walls with enough space to put another split-system which would make sense to do. They have big sliding windows & patio doors so no place for it (other than the master suite, & then "it" would be arctic & wouldn't help any other room).

        I was looking at placing the one box unit in my office to blow across the entry to my son's bedroom in hopes it would serve us & then the one split could possibly be enough to serve the rear side of this place. The property manager swore that the A/C was great & cooled the whole place…grrr. Is there any such thing as an honest property manager?

    • You beat me to it. Well done.
