MYO Air Conditioner

Most of us look forward to summer in anticipation of beautiful warm, sunny weather. However, once it arrives it can quickly become a little TOO warm! Here’s a simple, dirt cheap way to MYO air conditioner and drop the temperatures to a comfortable level.

This simple homemade air conditioner cost us less than $12 to throw together. The cooler was $2.50 at the Dollar Tree, the fan was $8, I found a piece of PVC pipe in the garage.

MYO Air Conditioner aka Swamp Cooler

You’ll Need:
1 cheap styrofoam cooler
a small piece of PVC pipe (or you could cut off both ends of a plastic water bottle)
a small 4″ to 8″ fan
Ice

First, remove the top of the styrofoam cooler, flip it upside down (the side that faces the INSIDE of the cooler). Place the fan on it and draw an outline with a pencil or pen.

Carefully cut out the shape of the fan. I used a filet knife from the kitchen, (don’t tell my husband).

Next, flip the cover back over and gently seat the fan into the cover. Now, cut out the vent pipe hole the same way.

Trace the PVC pipe onto the side of the cooler.

If you don’t have a piece of PVC lying around, you can cut the ends off a water bottle. Basically, you just want to be able to vent the Cool air and direct it out.

Fill the cooler with ice, as full as you can. Since this is a cheap project we just fill four one-gallon jugs with water and freeze them. Place two of them into the cooler at the same time.

While two are being used, the other two are freezing (see where I am going with this??) then, when the other two that are in the cooler have thawed completely, place them back in the freezer, switching them out.

We built this “swamp cooler” in order to cool down our greenhouse. With temperatures outside reaching 95F already this year, the inside of the greenhouse was frequently reaching 135F- effectively cooking the tender plants inside.

Timeline of Cooling Effects

I’ll bet you’re wondering, “How long does the ice last?”

Well, that is entirely dependent on how the room is that you place it in, how large the room is, what the moisture levels are for the location of the “air conditioner” etc. This will cool a small room, about 10′-16′ for about 5 hours in 85F weather. Give or take an hour.

Some people have reported that this adds too much moisture to their homes, but for our particular area of relatively low humidity, we haven’t experienced this issue. Also, as I mentioned, this swamp cooler was built to cool our excessively hot greenhouse, so added moisture and humidity is a plus!
