DIY Homemade AC

STEP 2: PREPARE THE PLASTIC BUCKET

Now that you have all of the materials and tools listed on the previous page, it's time to make the 5-gallon plastic bucket.

First, fill the 5-gallon plastic bucket with approximately 2 gallons of water. Mark the level and add some dry weight with an object like a brick. This will give the bucket some stability while you're working, or you can leave the water in the bucket in there which will also work as weight.

Next, make some holes in the wall of the bucket. You'll want to ensure to keep the lowest ones above the water line. Also, make sure the holes are evenly spaced out around the unit.

Now it's time to cut the pad to fit.

STEP 3: PREPARE THE PAD

Next, you'll need to cut a piece of the pad. The measurements are 13-14 inches high and 30-31 inches around.

As you'll later see demonstrated in the video, a long straight-edged ruler will make this step a lot easier and tidier. Keep in mind you may have to trim quite a bit to get the paid to fit just right. At this point, it's smart to take down the final measurements of the pad so that if needed you an easily cut a replacement. You'll also need the measurements for the next step as well.

The video at the end also does an excellent job at showing you how the pad fits as a visual.

The cooling pad will hug the walls of the 5-gallon bucket, and a screen will help hold everything in place. Learn how to set that up on the next page:

    This may make you feel cooler but actually adds heat to a room (remember to cool you have to transfer the heat somewhere else). You can make a two bucket system with two fans, one set inside and one out that would actually cool, but you have to connect then through a wall or window somehow.

    Hey that’s no joke. I actually built one of those last year and bought the copper, water pump, etc to Julie another one here just in case. Lol

    We used one where i used to work in va. Feels about 5 to 10 degrees cooler. Its a swamp cooler and when its 90+ makes it feel a little better but its not an air conditioner and uses the water quickly.

    Swamp cooler, not air conditioner. It puts humidity into the air, which makes things worse here in the south

    It’s not A/C, it’s a swamp cooler. They can be useful, so long as you don’t have high humidity already.

    Yeah during a blackout I’ll just go out and get myself a shovel full of snow

    They don’t create high humidity, but they will raise it up to normal levels in especially dry areas. They use evaporation for cooling, so as long as the water is evaporating, it’s cooling. 🙂

    Only works in dry places, not in humid climates like you’d need. Also, I’ve made a few ice A/Cs different methods, and they are very inefficient. A whole cooler of ice barely cools a small cab pickup for maybe an hour before it all melts. Best bet is to find a way to run coil through whole… large blocks. Still were fun to make though.
