Just ordered two for our large casement windows upstairs in the kids bedrooms. Got an estimate for double hung windows to replace our nice casements so we could run portable air conditioner units in their rooms and needless to say, this product here is the best fiscal solution by far. Kids have been sleeping in the basement for the last three summers. God Bless you for creating this product! I priced custom cut plexiglass through Lowes and it was slightly less expensive but with thinner glass and no nicely cut hole. Cheers!

Im so excited to have come across this video. I'll be measuring and placing order in the morning. Brilliant!👍

[@fingen49]

Nice solution for a casement window solution for room AC.

[@firesfrixtion]

Just watched measured and confirmed payment this is what we needed!

[@JennySnowy]

Oh man, so with windows that open like that, you can get plexiglass the same size of the frame, that fits into the groove of the window probably with foam tape to create a seamless and protected edge, and cut out a hole for the hose to attach into. It will be clear, better working and better looking than the cheap fabric cover. I only know this because I use a portable air conditioner and I go down a rabbit hole of all the information out there when I get invested into finding the right one for me.

[@brokenology]

I clicked on your video because I was interested in your setup. Turns out we live in the same state. I will definitely be buying one, if not two full setups from you and your wife.

[@MartinsonManufacturing]

Oh, very cool!

PS thanks for the tip. My ac on top of my camper died and I had to get emergency replacement.

[@margaretadams537]

What a great idea, wish you were in the UK

[@wolfc8755]

Forget measuring the hose, just use the hose connection hole that's already in the window kit (every ac should come with a window kit) as a template for the plexiglass.

[@katik.4833]

This is so helpful ! I’m relieved you have created this solution! Will be ordering from you.

Purchased: August 2022 - still works GREAT! kzbin.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn I live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install.This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment.I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

[@eva5601]

I don't think that any bird will nest in the duct once the bird feels that hot air burst out of the duct.😂

[@user-vr6xd7by3b]

smart idea. Thank you😊

[@ossiemoore941]

Brilliant.

[@MikeorJill]

Thank you. I share this with all our residents.

[@junederrico9180]

This is so good but Im having a problem with the casement window in the wind coming back towards the window .when it happens the exhaust comes back towards the unit and the hose gets really hot. I dont know how to get the window off the crank

[@FatJohnnyD]

Looks like a great product. If I have an extra screen that I’m not using that fits my window, could I simply super glue your insert to the frame of the screen and use the screen’s spring locks to hold the screen and insert in place? Thanks.

[@sifud2417]

Genius bro 💯

[@danfraser107]

Hi, thanks for an exceptional, informative video! I have a Class A RV with a fixed window (not a casement window or window that opens). It's a small window. I can remove the window casing to have access to remove the window. Can I replace the fixed window glass with your clear acrylic to mount my portable AC exhaust hose?

[@mrmrcory1]

My window hinges out just like this but doesnt lock i dont know if yours does or not but how do you go/would you go about protecting the actual window pane from wind taking it off its hinges?

[@sharonmccarthy5531]

This is awesome! Any companies in Canada doing this? 🇨🇦

[@187g]

interested but my casement window has no slot for window screen. limited space for double sided tape. didnt really understand the idea of generic screen clips. how to make sure that would work ?

[@KenzieTeno]

Are these waterproof? Or how does it keep rain from coming in the window if it's not sealed?

[@user-tn5rm2cj8y]

I need to vent a 8 inch hose. Do yall maybe make the adaptor piece in 8 inch?

[@Pog_Mo_Thoin]

This is great. One question, can you create a mesh screen for the hose adaptor to keep out insects?

[@MartinsonManufacturing]

Yup, we already have one developed. You can choose the bug screen vent on the order form: martinsonmanufacturing.com/products/portable-ac-casement-window-vent

[@ericfung7966]

How can we enable to stop the windows from blowing on this plexi glass set up?

[@mwnitz]

You mentioned that you could secure these with clips from a hardware store. Do you have a link to them so I can see what these look like? Thanks.

[@ricky_ricardo]

What is the part called that slips on the hose and locks into the plexi glass

[@needasickduck]

Hey!!!! You are my hero man I'm from Wisconsin and been looking to get an ac for my bedroom but these casement windows are rough to deal with. Plexiglass, how did I not think of that! You sell inserts you said?

[@MartinsonManufacturing]

Hey fellow Wisconsinite! I do sell them. There's a calculator on our site here: martinsonmanufacturing.com/products/casement-window-vent. Just enter in the size you need and it will tell you the exact price.

[@everennui1]

@@MartinsonManufacturing Hello, fellow Wisconsinites! Well... actually, I'm a stone's throw from the Mississippi on the Minnesota side, but it's good to know you're from Wisconsin. Would this work for an exhaust during the winter months? I've read that acrylic is better than glass for insulation, but I'd like to know if you've tried this. Thanks a bunch!

I plan on moving my air conditioner from my office to bedroom each day. Is there a cover for the hole in the custom window insert, how long from ordering to getting the item?

[@MartinsonManufacturing]

Yes, we have vent covers for sale. If you place an order, it will be in your hands in one week.

[@vincevileborne]

Well I’ll mention this now… I will be a serious inquiry. I have a special situation that I will Have to call and explain. I have a “sectioned” casement window with mirror tint on it. I need one of the squares at the bottom cut out and a hose with vent to replace it.

[@madbeetle4470]

Do you have any suggestions for a material alternative to block sunlight/people from seeing in? The room I am looking to cool has my gaming PC in there, so I prefer to be able to dim the room and importantly I don't want such an expensive easy to carry item visible from outside. In fact if you're willing to make such a custom insert I'd be happy to order from you.

[@MartinsonManufacturing]

Yeah, we offer frosted plexiglass as well as black. We don't have an option to select those options on our website, so just tell us which one you want in the order notes at checkout. If you'd like to order one you can do so here: martinsonmanufacturing.com/products/casement-window-vent

[@denisesavannah2023]

My landlord installed a new window and there are cranked windows just like the one you have.. that's going to be tricky I'm not sure why they want to install that kind of window they forgot about the air conditioners..😢😢

[@user-wi5sj1wv3r]

Where in WI are you?

[@sashineb.2114]

Hello, have you tried this with a Midea duo-hose system? They told me it wouldn't work in casement windows. But I don't see why an insert with opening cut in won't work. A friend has the same windows I have and his LG (single hose) vents perfectly. Many thanks.

[@MartinsonManufacturing]

Yup! We do inserts for that unit all the time.

[@jalbor]

This is suuuper helpful. I may try to make this myself. Any recommended tools for cutting plexiglass?

[@MartinsonManufacturing]

Try a fine toothed jig saw

[@user-nr6sb2fe7b]

What about a casement window that opens IN, not out? Also can you ship a plexi 95" long sliding door insert if I ordered?

[@MartinsonManufacturing]

For those we typically do the same method, replace the outside screen with the plexiglass panel. We could make 95" happen, but shipping might get a little crazy. Send me an email and I'll get you a quote: [e-mail]

[@Jade-ms2ys]

Is it safe to vent through a screen? And someone said to use Lexan instead of plexiglass do you have an opinion? Thank you for your video

[@Thommadura]

No - Do not vent through a screen. THAT would allow the hot air coming from the Air Conditioner to flow around and back into the room along with Humidity. YOU CAN - if you do not need to see through the window - replace the screen with a thin piece of Plywood or fiberboard - but Paint it to protect it against the weather.

[@HooksUSD]

Whats the best way to cut a hole in the acrillic?

@@user-jz4th4mb6f I did pretty much exactly what he does in the video, but with a vinyl shower curtain I cut to size instead of a solid piece of acrylic

I would love to share ur company our my town in mn seriously very few options on the market and I would absolutely love to help you get more than people seeing ur website (hoping you’ll have own) pls lmk I don’t want your money this is just seriously so needed especially in older towns

[@PinkgalMHC]

What does something like this cost, on average? For 1 standard sized window and 1 hose to vent.

[@MartinsonManufacturing]

$220 is the average cost.

[@afgromeo929]

Does air enter through exhaust hose while the portable AC unit is off?

[@thisGuy481]

Probably. But you could always just close the window.

[@yhenalcoreza8512]

How did you cut a hole on it? Ace just told me that they don’t and can’t cut a whole because it might break :(

[@susanholcomb]

I bought a flourescent light replacement panel. It's plastic. You can cut it with an xacto knife or box cutter. Then tape it on with masking tape. Not the prettiest, but it works. It would be nice to have a pretty one.

[@vanlifenomadgipsygirlcanad2195]

Had exactly same question

[@orinn777]

Do you sell an insert cap for the hose hole if I want to disconnect the hose but not remove the insert?

[@MartinsonManufacturing]

Yes I do. It’s not listed on the website yet, but customers can just tell me in the order notes that they want one and I’ll throw one in for them.

Nope. Customers typically hold them in place with double-sided adhesive or Velcro.

I just bought one of those Midea ACs, but I haven't picked it up yet. I wrote to Midea to ask if it would work in a casement window and they said no. But I don't see why it wouldn't if other portable ACs can be vented OK. Have you installed yours yet?
