Install an Air Conditioner in a Sliding Window

We finally decided we had enough with the heat, so we ordered an air conditioner off of Amazon. The problem was, this one was designed for vertically sliding windows, something we didn't realize until we tried to install it in our horizontally-sliding casement* window. As I looked at other people's creative solutions, I came up with this. Three days and going strong, so at this point, it looks like a success.
*Edit: D. Reichart pointed out to me that this is not actually a casement window. Casement windows are the ones that crank open. My apologies.
I feel I've gotta expand on my disclaimer -- please think about my design before using it in your situation. I'm sure the manufacturer would say this is a stupid idea, so proceed at your own peril. It hasn't blown up or fallen out of the window -- yet -- but I haven't thoroughly tested this. In other words, don't blame me if something goes wrong. These things are heavy!
Ingredients:
Air conditioner
One 6-8 foot 2"x2"
One 3-4 foot of 1"x4"
One package Command Adhesive Velcro strips
One 1.5" screw
A piece of plexiglass that fills the area above the AC unit
Masking tape, or something like it
Foam, if your air conditioner didn't come with any
Please forgive the choppy editing -- I got a new camera, and my video editing software isn't playing nice with the files, so I had to use Windows Movie Maker.
1-Year Update:
We finally installed it for its second summer of use (I love Oregon). It would have gone very quickly, but we needed more foam to fill the gaps, so I had to run to the store. But the installation was very easy. I just had to go back and rewatch the video to make sure I was doing it right!
2-Year Update:
Installed it again after rewatching the video as a refresher. Still no changes in the techniques I used the first year. The hardest part was washing the second story windows; other than that, it was just a matter of following directions, cutting the foam to size, and enjoying the cool air. Everything still seems to be as solid as ever!
3-Year Update:
It only took about half an hour this year, and that's with a hurt shoulder. All we bought this year was some new foam, and we were golden.
4-Year Update:
Ours went in no problem, and we still had time in the same evening to build and install a new one for a relative.
5-Year Update:
Both the relative's AC and mine are still rock solid. There was some paint loss on the window ledge of the relative's apartment (crappy paint), but with enough Command Adhesive, we got it stuck down.

It’s nice that he’s still responding to comments 7 years later.

I only have two videos that get regular comments, and the notification pops up on my phone, so it's not that hard. Besides, I don't really use Twitter or Instagram or Tik Tok or even Facebook, so responding here is my form of social media. Keep saying nice things, and I'll keep responding. Disagree with something in my video, and I'll have a respectful debate with you. Try to troll me, and I'll make fun of you. No matter what, I get something out of responding!

[@fareehaaaa]

@@PacoWarabi well, we hope your doing good right now, we just want to know how's that AC now, is it still there or you changed it?

[@PacoWarabi]

@@fareehaaaa I'm still using the exact same setup, and it still works great. The only issue we had this summer was right after the massive wildfires in Oregon, we had a massive rainstorm, and for the first time in 6 years, we ended up with water leaking in. I will have to think if we will change something for next year, but this really was an unusual situation. We never get rain like that.

Haha true

[@KentQuickstad]

We do, but they cost 3x as much.. ugh

[@teerich2011]

Depends on the width of the window but there are various sizes. His window could take a huge window unit. Sadly my windows would need a casement air conditioner (thin ac) that IS 3x as expensive and only see to be popular in the northeast part of the US. I never even knew a narrow ac unit existed till I started researching based on 15" width

You're very welcome to come up with your own system and put it up on KZbin. But I'm not an air conditioner specialist - this was a hack that works well enough for my situation, so I'm sticking with it.

How does that make the person a legend LOL? It all goes by when a person does Googling, it could be done a day after this video was made or 20 years later. Just because somebody is inputting something in Google that happens to relate to this person's video doesn't make this person a legend!

Ya know what? I just like everything about your idea, your video and you. At the beginning of the video - when you were finished talking about the A/C and kind of slunk down and walked across the camera, I thought; "was that just comedy genius I saw".

We chuckled at the start of your video because 80F looks pretty cool to most of us in the western US right now. I'm in the Seattle area, where houses are built for neither extreme heat or extreme cold. And we've been getting both. Over 100 for days in a row. It's a great tutorial and hopefully we'll be able to put your advice to successful effect tomorrow.

[@meowJACK]

It's not very empathetic to chuckle at someone's suffering. Just because you are experiencing worse temperatures, doesn't mean that the suffering of others should be laughed at. 80F with no AC can still be very very uncomfortable, there's no need to laugh at people going through that

[@PacoWarabi]

Also, not to brag, but it got up to 117 here this last summer.

[@KentQuickstad]

@@meowJACK 80F with no A/C is objectively less suffering than 100F with no A/C, so not really sure what your statement here is trying to convey... Also to be fair, 80 degrees is extremely manageble with box fans in the windows exhausting hot air out of the house at night. 100 degrees is a different story completely...

[@TheOzthewiz]

Wow ! you did that the hard way dude. I made a plexi-glass window in its own frame that fits perfectly in the window casing slots without having to use the cheap plastic side wings. I do have a crossbar to hold the top of the air conditioner also. NO gaps, slide the air conditioner in and out with ease, painted to match the window, and three screw ( I drilled holes at either end of metal air conditioner top metal bar. People think that I special ordered this with an airconditioner built in ) . Tee Hee, if they only knew the truth I'd be making this for everybody.

[@RichardTurlington]

Was so hot yesterday - the wife & I got into an argument about my wanting to go get an AC unit from Home Depot while she stayed at home with the kids. Realizing our snappyness was probably due to the heat I bought TWO AC units. Got home and realized there was no way to put them in without special hardware. Starting looking on Amazon - then found your video. I immediately headed back out the door to Home Depot with 20 minutes left before they closed. Though they didn't have 2x2's, I bought 1 3/8 x 1 3/8 instead and it worked well. I did the install of both units in under an hour. Couldn't have been more simple or cost effective. I too live in earthquake country, so I'll also be figuring out some type of secure strap that I'll bolt to a stud in the wall on the interior... but in the mean time, as you said, "Good enough!" One last thing, I live in an apartment and drilling into the casement windows is NOT an option. This solved that problem too. :) Thank you again!

Note from my neighbors here in Cactusland...ALWAYS turn the fan on for a couple of minutes before cold-starting any compressor. Same sequence in reverse for turning off. Cool off for a few minutes to let the compressor "rest" then the fan. I really like the simplicity of the box frame mount. Since I'm on the ground floor, I'll make the box more "secure." Great video and short, too. Just scored a freebie Zenith 5000t8! Luckily, I don't have direct sunlight on my window. Makes all the difference!

I Loved your idea, third year using my set up and working fantastic. I did close the window as much as possible right up against AC (accordion flaps not used) and use a sliding window lock to keep the window from being opened. I used thinnner wood pieces for the top and bottom wood to keep the gaps smaller (I have a light LG unit). This has saved my upstairs office and I'm getting ready to do it for our upstairs bedroom and get rid of our loud portable unit - yay! Thank you for sharing!

[@PacoWarabi]

I'm so glad this helped! If I were to do it again, I'd skip the accordion flaps. But since the plexiglass is already the right size, I just put them on year after year.

This makes me pine for the good ol' days of KZbin. 11/10

[@davidmarek7281]

Thanks so much! I just bought an AC unit for our master, since it is going to be about 110-115 this week. We had a hell of a time trying to figure something out to keep it sturdy, this looks like a great idea! Will try tonight!

[@PacoWarabi]

Did it work? 115 is just way too hot.

[@johnmimms9167]

i love the end of the video. he is silly!

[@Staplegun]

It's incredible how the AC was able to release your hair from it's knot, and even gave you a nice clean shave! :D

[@PacoWarabi]

I paid a premium for that feature. That's why I had to build the frame myself!

Hey man thanks u are an inspiration i had my ac sitting and waiting to be installed, but than i watched ur video and intatalled it myself in less than 5 mins

[@marywemigwase3354]

Oh my god there is hope for my oven apt yet! Thanks for your time

[@PacoWarabi]

I was so excited when I got my AC, and so disappointed when I realized it wouldn't fit in the window. Hope this hack helps you find a way to make it work. Air conditioning is amazing!

[@amb5151]

Thank you, this is extremely helpful!! Just did this myself with very minimal tools (got the wood cut at Lowe's) and practically zero home improvement skills. Got it up and working in less than an hour. I'm still a little afraid of it falling out of the window but it seems sturdy for now!

[@Reggeroni]

Thanks very much for making this video. I followed your directions step by step and.. viola! It came out el perfecto!

[@edsalinas9996]

Paco, artist tape is for Artists, and that is what you are! Keep rockin' Bro!

[@new-knowledge8040]

My apartment windows are also side sliding windows. The total height of the window, was twice the height of the air conditioner. So what I did was remove the side expansion panels, bolted the two of them together, and mounted them on top of the air conditioner. They were a tad bit taller than the air conditioner, and so they also fit into the window slide notch at the top, and thus were being properly held in place. Fortunately, when bolted together, they were exactly the same width as the air conditioner, plus a tad bit more. That allowed the panel to also fit into the window slide notch at at one side, and thus it was again being held firmly in place. Once finished, I just slid the slide window on over to meet up with the air conditioner and the bolted side panels. Job done. The way in which the conditioner itself was mounted for stability, took a little bit of work. But, it is basically Earthquake proof, and it required no additional parts. Everything I used had come with the conditioner.

[@PacoWarabi]

Very nice! That would make a great video as an alternative to my technique. I like that you don't need all the extra wood in your system, which doesn't just require the wood, but woodworking tools as well.

[@new-knowledge8040]

It seemed bizarre that the extra odds and ends that came with the conditioner for different vertical sliding window types, was all that I needed to make it mount to a horizontal sliding window type. Drill a few holes, bend a piece of metal, and that was about it. I had to make sure that it was mounted rock solid because below my window is an apartment entry door. But that position also meant that water would be dripping on peoples heads as they enter. So I took an old dead AC adapter and turned it into a sort of square cup. This cup catches the water than drips out of the air conditioner. From the square cup, I have a rubber tube that redirects the water flow off to a safe area. With is set up, I can at any time pull the air conditioner from its frame to service it or clean the inside. Otherwise I would have to get a ladder to disconnect the tube on the outside first, and do the same again to reconnect it later on.

[@PacoWarabi]

I really want to see a video of your setup. It sounds like you came up with a very elegant solution.

[@new-knowledge8040]

imgur.com/a/DEDBtcP My apartment window is divided into a large upper window, and a smaller lower window, which is where I mounted the air conditioner. I took the two expanding side panels, bolted them together, and placed them above the conditioner, and it was a perfect fit. So the window is completely filled. Sliding the sliding window, which is on the left side, on over to meet up with the conditioner, is what takes care of matching the air conditioner width. On the outside, there is a cement ledge, so I have two adjustable posts that sit on the ledge. In turn, there is no force being applied to the window. On the left side of the air conditioner, there is a white "U" channel. The sliding window handle actually can be moved up and down, and so I moved it down such that is mostly inside the "U" channel. It's a snug fit, and so that keeps the sliding window always in its proper place.

[@new-knowledge8040]

Recently my air conditioner developed a growth of slippery slimy clear goo that led to blockage of water flow. But problem solved. I gave it a dose of mouth wash, and that killed the slippery transparent goo.

[@trixsta54]

For everyone who has this problem with these type of windows can try looking up "Vertical mount air-conditioner units" believe it or not they actually do have them. Same type of unit, same price range, but made for vertical windows. This video however is great and offers great ideas for those who already have these types of units and are good at doing all the modifications.

[@PacoWarabi]

+trixsta54 Thanks for the heads up. Where are you seeing them for comparable prices? The lowest price for vertical mount air conditioners that I can find on Amazon is the Kool King 10,000 BTU air conditioner, for $396. You can get a Frigidaire 5,000 BTU for $119, or a 10,000 BTU for $306. It seems like there are very few options for slider windows. I created this video originally because I bought my A/C without knowing the difference between types of units, and got the wrong kind. If I had followed your advice years ago, I could have saved myself all the work, but wouldn't have 350k views!

[@davidinseattle2008]

Thanks Paco👍🏽! My girlfriend and I followed your advice and 40 minutes later we were having an "ice day" in 92 degree Seattle 😀

[@michellesimpsons356]

Thank you. I never thought about the plexiglass. I’am so excited to try this myself. wish me luck. .

[@PacoWarabi]

Good luck!

[@kdl8932]

Great vid! Thanks for taking the time to make it... helps dummies like me.

[@APNambo]

The end was gold!

[@MimsymomerathShop]

This looks like a solid plan to me! Better than any of the other videos I watched.

[@PacoWarabi]

Eric, Good questions. I think it's strong enough because while gravity is pushing it out the window, it has the entire 2x2 stopping that from happening. The screws they gave me to screw it into the window frame wouldn't have anything more than that. The velcro strips are Command Adhesive strips, which in my opinion, are plenty strong. The artist tape is basically masking tape, but made for artists. It's just higher quality. And finally, just keep in mind that your results may vary.

[@MR-pv7qg]

Tank you so very much . I installed my unite today. All the best to you!

[@traciekalkhof2268]

I had to put my AC in by myself because my boyfriend was busy. I had to search around for material to use. After 2 hours I got something secure enough to put it on. It was very heavy to lift myself, but I was determined. It doesn't look the greatest, but it won't fall out and it works. Thank your

[@slydegaming1932]

Plexiglass looks a lot better than plywood too.

[@BurnBlisterPeel]

This malarkey is happening in my house this weekend!! Thank you so much for the detailed instructions. xoxo

[@PacoWarabi]

So glad I could help!

[@stevenmorgans931]

That part about using plexiglass, never thought of that! I've held off getting one of these because I see so many installed with plywood above. I also like that you made it completely removable after the 7 or 8 days a year that it's actually hot enough to need one in the PNW.

[@PacoWarabi]

Steven Morgans I saw the same thing with the plywood. I wasn't willing to lose that much light, so plexiglass seemed the way to go. We use ours for a whole month in Oregon. Must be hotter here :-)

[@PacoWarabi]

Kody Petkovich Yeah, it's time for some A/C.

[@JordanOMara]

I used this exact method to install 2 window units in my townhouse. Great instructions!

[@Vynyard]

Thank you!!!! You totally gave me the confidence to try this. I got it done!

[@PacoWarabi]

@@Vynyard That is absolutely wonderful! Having an AC unit is a life changer. So glad this helped!

[@SweetHart..]

My housemate built a frame for ours. Worked perfectly and protected the back part of the air conditioner from the rain. Put it in the window in late Spring and left in there until Fall. The frame fit in the window perfectly with plastic window above the conditioner.

[@911V3N0M]

Thankyou!! THANKYOU!!!!! I can't believe how derpy I was and didn't think of the top wood bar. This whole set up is so much nicer, I'm glad I came across your video and thanks for making one! Now I can keep flys out AND the cool air in 😊🤩 Have an Ice day too my guy 👍

[@PacoWarabi]

You're very welcome! My original idea was to rebuild an entire wooden frame to simulate a vertical sliding window, and then I realized the only piece doing any work was the cross beam.

[@krist_714]

This helps so much!

[@shanegates6329]

Also in Oregon, ty for this guide, I did the same thing (ordered a fridgidaire off Amazon in a fit of heat induced mania at 3 am) and am now preparing to chill myself

[@PacoWarabi]

Our first summer here, we made it with no A/C, and then decided it wasn't worth trying to control temperature with just opening windows. Good thing these last few days, with the near record temperatures and then not opening windows last night due to the smoke. We've been running the AC nonstop.

[@mollyjr3]

We attempted to use two different brackets trying to get our small window to work and was about to give up on the window altogether when I found this video and it is 100x more stable than any of the brackets, less gaps overall very happy to have given this hack a try. Thanks! Saving lives and sanity

[@PacoWarabi]

Oh yay! Since we're renting, brackets weren't even an option, but glad that this works even better. It was in the 40s today in Oregon, so it's not even close to AC season yet. Stay cool!

[@1christine1001]

I closed the windo to contact the air-conditioned, and but a 1"×1" to prevent the window from opening wider. That eliminates the need for the plastic sides that accordion open. Made a screen for the remaining window so I can remove the plexiglass and get a some fresh air in the room.

[@PacoWarabi]

Great modifications. If I were to do it again, I'd remove the accordion wings as well, and I love the idea of adding the screen. Way to take the basic idea and make it better!

[@smurda13]

I found this after a search for a solution to my problem. Not only did i laugh, but i learned. Anyone else notice that after you turned on the AC, not only did you let your hair down, but you shaved lol

[@smurda13]

Also it seems the recent heatwave has brought this video back trending lol

[@PacoWarabi]

@@smurda13 This has been up for something like eight years, and each summer I start to get tons of views. The funny thing is I get comments in December - February from Aussie viewers, because it's summer in the southern hemisphere.

[@smurda13]

Well thanks to your video, I was able to get some ideas on how to complete my fit for my window AC unit yesterday. Now my son has his own AC and i can sleep in the bedroom again instead of the living room lol 😂

[@PacoWarabi]

@@smurda13 I'm glad this video helped! Sounds like you used the video the way I intended - take the ideas, then modify it to work in your situation, and probably improve on it as well. AC units make a huge difference in sleepability.

[@rockycolo340]

How do you make sure the a/c tilts down so that it drains properly? I am so glad I found your video. I am a renter and landlord gave permission to install a window a/c in slider window. So happy to do it without permanently modifying the window.

[@jjbarajas5341]

Thank u sir ! After looking at a bunch of KZbin videos and how to articles, I looked at my window and my AC and this method is the only way I could get my AC installed, thanks to my crappy window from the 70's. Instead of plexiglass though, I used some white corrugated plastic and put a flexible diffuse acrylic sheet in top of it to face the outside. My local hardware store's glass cutter was unfortunately broken at the moment. Might get a plexiglass sheet next summer though!

[@PacoWarabi]

Love the white coroplast idea. Even if it's opaque, I'm sure it lets in a lot of diffused light.

[@lonniemcclure4538]

@@PacoWarabi - Standard coroplast becomes embrittled with long term UV exposure. I know that from experience using it for window fills (which I no longer do). It was quite evident if was UV exposure, as an area near the top that was shaded was unaffected.
