We can all agree that the worse part of summer is the unbearable heat. In most parts of the world, summer brings along at least a few weeks of smothering heat and humidity and, for the most part, the entire season is that way. Even if you love the hot weather, air conditioning is essential in this intensely warm season. But what happens if you’re living somewhere that doesn’t have AC or what if your AC has just given out on you at the worst possible time? Well, suffer no more. You can MAKE your own air conditioning using a basic box fan that you can buy at just about any store. Watch the video below to see how you can create AC for little to no cost at all.

Sound too good to be true, right? Air conditioning that you don’t have to pay a fortune for – yeah, right. While this may not be the central air conditioning you might be used to, it really is an efficient and functional way to cool your space down without spending an arm and a leg!

The system works because of three separate parts: the copper coil, the ice water, and the basic box fan. The ice water is sucked into the copper coil which becomes freezing cold. The coil is attached to the box fan, which then blows out freezing air from the ice water in the coil.

If done correctly, you can create a mess-free cooling system for only a few dollars! All you have to do to keep up on your DIY air conditioning is replace the ice when it starts to melt away. Definitely worth saving all the money.

Here’s what you’ll need to get started:


  • Box fan
  • 2 copper coils
  • Zip ties
  • 1/4″ compression unit
  • Wrench
  • Clippers/Scissors
  • Plastic tubing
  • Bucket
  • Ice

Step 1: Lay out your box fan and start to slowly unravel the first copper coil on top.
Step 2: Unravel the second copper coil. Zip tie both coils down.

Step 3: Use the compression unit to connect the two copper coils.
Step 4: Snip off the excess of the ties.

Step 5: Attach the plastic tubing to the end of the copper coil.
Step 6: Put the ice into a bucket and stick the end of the plastic tube into the ice water to get the cold air flowing.
