People spend a lot of money on air conditioners. If you don't have the money at the time your air conditioner breaks down, make one yourself! It's easy and cheap. Using this type of homemade air conditioner can cool down one room. The only thing you have to do is to make sure you have frozen liters, dry ice, or frozen gallon water jugs. Make sure you have one of these items at all cost. That way if it melts, you can just refill it.


  • 1 Foam Cooler
  • 1 Elbow Dryer Tube
  • 1 Small Fan
  • 2 Bowls
  • 2 Frozen Liter Bottles



1. Measure a hole on top of he cooler lid using the elbow dryer tubes and a marker.

2. Cut it using a knife or a blade. Be careful and don't cut yourself.

3. Measure the second hole using the small fan. Use the same method to cut the hole.

4. Place the elbow dryer tube in the hole that you cut for it. Tape and seal it using duct tape. This will prevent any air from leaking in.

5. Place the small fan in the hole that you cut for it. Tape it using the same method as you did for the dryer tube.

6. Place the bowls inside the cooler. You may need to switch to a smaller or bigger size if the bowls don't fit. You will use these bowls to catch water.

7. Place your frozen liter bottles inside each bowl. As the bottles de-thaw, the bowls will catch the water.

8. Find a place in a room that you want your homemade air conditioner in next to a plug in. Plug in the fan and turn the fan on high.

9. Enjoy!


My Experience

My experience while using this method seemed to work very well. I prefer to use gallon jugs because they last longer. Dry ice makes it colder, but can be dangerous to use unless you have had experience with it. I have one of these in my bedroom during summer and it does help a lot. I place a rotating fan by mine to circulate the air around. Putting it all together was really easy. You just have to make sure you measure the holes the right way. If there is a gap, you have to use a lot of tape. You want all of the air to come out of the dryer tube.

      My home (like many around here) doesn't have air conditioning, because it rarely gets so hot that you need it. But I am particularly susceptible to heat, so there are those days where I really wish I had one. I'm going to collect the pieces to make one of these and keep them handy for those scorchers. Thanks, Brittany.
