How to build an air tight insert for a window AC unit

[@mel_tillis2]

Thank you for the great demo, the use of GREAT English, clarity and volume of speech - PERFECT 👍👍👏!! Glad you're a Kreg lover as am I 😁. Need to make one of these for my gaming room but my skill saw has died. I LIKE that Kreg saw and brake / dust filter!!! Off to find a Kreg skill saw.....

The cumulative effect of water condensation on, (particle board)? could be problematic?

[@keithruck]

Nice idea for long term. Making one tomorrow. That board was 60 bucks. Lowes wouldn't sell a half sheet. Yours looks great.

[@extracurricularbuilder2777]

Thanks brother. Good luck! Hope it works well for you. We finally have central air in the house, so I made a new insert for our little detached garage, and that’s where the window AC lives now.

I like what you said at the end man i'm no handy man by any means but dude i got these ideas floating around that i'm dying to try out

[@spdracr4life]

great idea but i see one problem with this, the unit is going to have water draining when its humid outside and that it going to pool up on the wood and might seep into the MDF unless the paint you used is waterproof 100% to protect the MDF?

[@aprilrobbins5220]

Came here to comment same that it was a good idea but ac will be sitting in a puddle. And depending on the unit it may need more if a slant.

[@Airbender24B]

He just needed to add a little slope to the shelf.

[@JoshuaStranger]

MDF seems like a bad Idea.

[@extracurricularbuilder2777]

MDF probably wasn't the best choice, but I had a sheet on hand. The paint held up really well, and I didn't have any issues. Also, I don't live in a humid part of the world.

[@micheleolson9914]

@@extracurricularbuilder2777 The humidity will be from the condensation dripping out. Maybe next time make the shelf shorter to end before the drip hole in the metal housing or install a drip tube thru a hole you drill in the shelf.

You should post affiliate links for the tools you used. Iv been looking at a track saw systems for awhile now just haven’t pulled the trigger on one. Also I’m never on Instagram so I’m glad you are posting here now.

[@extracurricularbuilder2777]

Thanks man. I love my track saw. So nice for big sheets of plywood and MDF. I’ll figure out some affiliate links. I’m not sure Kreg will give me one yet, because of my subscriber and follower amount.

[@garythomas418]

why did you slide the air conditioner in from the outside? I like the idea of building those side pieces instead of trying to support it from underneath.

[@SlimSavageBlanco]

How will the water drip from the bottom?

[@williamb454]

Looks good man!!

[@cashmagnetmarketing7316]

Seriously great job! Thanks for the vid :)

[@gilboston20033]

Nice job, I would make a frame to the upper part and add a piece of glass as long it does not weaken the project. Just a thought, but it looks really good.

[@wbishop1330]

👀 that is clean. What size or btu is ur ac. 👍✌️

[@weldlife373]

How is the water going to drain sitting on a board

[@alexandsimba]

I would suggest putting mosquito mesh around the openings of the AC. It will stop mosquitos, lizards, and leaves from making their way in the unit and contaminating the water that it uses to cool the evaporator coils. I am also not a fan of these companies letting the water linger inside as it will cause rust as the water slowly eats away at the metal. It's more energy efficient, but by not having a drain hole it also means you will have to buy another unit after a few years.

[@lipsofadon]

Very helpful. Thank you.

[@Airbender24B]

Nice job bro. Could you get away with only using a circ saw if you don't have a saw table or track saw?

[@extracurricularbuilder2777]

Easily. I used to use a circ saw and a guide for everything. Slowly upgraded over the years. This whole project could be done with a circ saw.

[@황태산-i3b]

Perfect🖒🖒🖒

[@blocknex]

some explaining would help

[@julieoliver8170]

First mistake MDF.

[@Airbender24B]

Can you elaborate please?

[@extracurricularbuilder2777]

MDF probably wasn't the best choice, but I had a sheet on hand. The paint held up really well, and I didn't have any issues even when it rained.

[@rvc9876]

MOLD MDF OH NO

You need to change the title to " How to over complicate a super simple task"

[@JIMMYJREVIEWS_thaiM-A-F-I-A]

Your blocking air flow , witch is VERY BAD for the unit , you have NO way for water to drip or evacuate , you went WAY OVER KILL on something ment to be simple . You probably didn’t have any experience with ac window units at the time of making this . With that shelf you will catch a heap of extra water that could flood your room ! Nice try buddy .

[@extracurricularbuilder2777]

It worked great. No water leakage into the house, no damage to the AC unit, and no damage to the window. Not to mention, it is much easier to install, and take down. No doubt some improvements could be made, but it’s done it’s job perfectly.

[@michaelarmenta8289]

How is it blocking air flow?

[@JIMMYJREVIEWS_thaiM-A-F-I-A]

​@@michaelarmenta8289 hello , If you look on the back of a AC window unit you will see a bright aluminum shiny piece of equipment that is called the AC evaporator. The purpose of the evaporator is to extract heat from the ambient environment And needs 4 - 5 feet of unobstructed pass-through airflow in all directions. Theevaporator much like your Radiator in your automobile. ‘’ The more COOL airflow the better ! ‘’ for the AC window unit to continue to perform optimally you need that Unobstructed COOL airflow so it can cool off whatever room your trying to cool off effectively and efficiently. I don’t know if you have been on the opposite side of your window mounted AC unit before but that sucker throws out a lot of ambient heat A LOT ! It’s almost comparable to the amount of heat that your clothes dryer throws out when it’s drying your clothes ! so with that being said the evaporator wants to be as cool as possible even though it is kicking out its own heat source and the evaporator is very close in proximity to all of this happening . So the evaporator is counting on having that 4 to 5 feet of unobstructed airflow because it’s kicking out its own heat source but yet it needs that cool airflow ! so if you build anything around this unit kind of like a cabinet or enclosure or anything that’s gonna trap hot air around your unit you’re forcing it to breathe it’s own hot air and it doesn’t like that ! lol not only is it bad for your unit but it’s also not gonna do its job efficiently to cool down whatever room you are trying to cool . On the bottom of your AC unit the mass majority of them have ventilation Vents that are all over the back of the unit .they are there so that the unit can get rid of all that hot air . building a enclosure like this guy did even though it is not completely sealed is definitely a bad idea ! not only are you trapping in all the hot air that the unit is trying to dissipate through the vents but you’re trapping dirt and debris they can also clog those thin aluminum fins or ‘’ heat sinks ‘’ on the back of the unit . So you’re making your AC unit work 100 times hotter and harder and dirtier then if done via manufactures instructions . Also if his AC unit is one of the types that has a small weep hole at the bottom for evaporator or condenser condensation The collected water needs to drip freely to the floor and evaporate if you have wood underneath it you’re just collecting all that condensation Drip water onto the wood causing mold and rot and bad smells all around it’s just not a good idea let me put it that way . Some window mounted AC units have a warning written on them stating that you should not drill holes on the bottom of your AC unit a lot of people see water collecting on the bottom on the inside of their AC unit and think it’s clogged or flooding when in fact it is made that way on purpose so that the condensation can be used to cool down the machinery while inside the unit . Another words do not drill holes on the bottom of your window mounted AC unit ! unless you see no factory warning sticker then you should be fine with a few drain holes of your own if you so desire . So another words don’t cover up your window mounted AC unit in any manner because it’s trying to operate and cool itself down to operate efficiently for you to have a cool room 👍🏻 I hope this was informative enough..thank you ✌🏻
