How To Build 2 Different Types Of Homemade Air Conditioning Units
(Option #1) Coleman Cooler Air Conditioner Unit
This blue beauty has a 45.5 L (48 qt) capacity and can hold 63 cans plus 7.7 kg (17 lb) of ice (That's before you turn it into a major air cooling Frankenstein). Its lid is hinged, and has "easy to lift" 2-way handles, and a rust-proof / leak-resistant drain.
Get yourself an old used computer fan from an old computer... for intake of warm air, and to circulate the air inside the unit.
The fan used in the pictures below is slightly larger, but this is the basic concept.
Use this as the vent for the exhaust of the cool air.
The extra added feature of this is that it's somewhat manually directional allowing you to tweak and turn the attached knob/lever.
Trace around the computer fan on one side of the lid, (the left side shown in this pic) and cut out the square.
Trace around the inner dimensions of the Floor vent on the other side of the lid (the right side as shown in this pic.)
Test fit both pieces, and trim if you need to until you get a nice tight fit.
Secure the fan from the top into the lid.
I originally used the clear plastic mirror mounts to hold the fan in place from the top, but then remembered that some people have pets and children who like to put body parts into interesting slots, holes and/or places that they really shouldn't so I ended up screwing on the safety grill as an added step...protection.

Secure the floor vent to the lid of your cooler with screws or bolts, whatever you like!
On the inside, underneath the lid of the cooler, I bolted my computer fan in firmly tight with some metal strapping. Now that it's completely secured from the top and underside of the lid, it won't slide upwards, fall into the cooler, or rattle and vibrate and drive you crazy!
*NOTE - Underside of floor register also shown for those out there who want to see the underside of a floor register.
I also ran the power chord for the fan out the back of the cooler by one of the hinges (secured that as well) and gave myself enough cable in order to move the unit around the room to whatever location you wish to make... cooler!
Inside the cooler, you want the air to be able to move around freely so the the cool air is blown out of the exhaust vent.
*NOTE - Warm and hot air rises and cool and cold air falls.
I took a piece of metal shelving and bent it into a "V" shape to fit into the bottom of the cooler... so that you can put re-freezable gel cooling packs into the bottom of the cooler, and air can still circulate around and underneath the packs.
Your gonna need a bunch of these re-freezable gel Pack whatchmacallits.
I purchased the large ones, and started with three inside the cooler. After testing I may add more.
You can use a bag of ice if you want, throw in a little water as well, or even add some cans of bottled water for later. It's all about experimenting and making progress!
That's really all... You should have something that resembles (or closely resembles) something like what you see in this pic.
Step 11 Ta Daaaaaaaa!
1. I used it as a foot rest / Ottoman and it cooled me down pretty well
2. The handles & long cable make it easy to move around and use in a plenty of ways and in different locations
3. I had fun building it... it was pretty quick and easy
4. Cold drinks
I think tomorrow I may head to Canadian Tire, and pick up one of those magnetic directional air flow floor vent scoop thingies!
Might also add more re-freezable gel packs to the interior of cooler (probably 4... will keep you posted!)

(Option #2) Simple Styrofoam Air Cooler
The A/C unit above works fine, but this one is the quickest, cheapest, and easiest to assemble BY FAR!! Also, I've posted another video below from someone who saw this video, built it, realized it worked extremely well, and created his own video after he made a few slight modifications to its design. Have fun, and stay cool!
