I had come over from the UK to look at a bazillion homes in a short period of time so I attribute my gullibility to jet lag and general lack of sleep.
But she said, and I quote, "Up here at 4000 feet, nestled in all these dense trees, you don't need an air conditioner." Um, right.
Big, fat LIE!
While I admit that living in a California mountain forest isn't anywhere near as hot as living in the Sacramento Valley (can you say 110+ degrees???), and we have far less concrete to radiate heat back to us through the night, so we do cool off beautifully. But we have hit the 90's here in the middle of the day and, frankly, that qualifies as needing an artificial coolant of some kind.
But my realtor was right about one thing. . .most houses up here don't have a/c. They either pull out an antiquated swamp cooler for the few weeks of really warm weather we get, or have a whole house fan that seems to do just fine.
And, really, in the three summers we've been back from the UK now, we haven't had more than 4 weeks of weather that I would be sorely tempted to use an air conditioner for. So buying a whole house a/c seems a little like overkill.
So, I did some research. Next spring we're going to be putting in a whole house fan (yippeee!!) and, if we feel particularly flush, we might add small per-room a/cs like they have in Europe. No need to connect to ducts and can go just about anywhere! Only one or two, mind you. . .just to take the edge off.
In the meantime, however, I came across YouTube videos showing how you can make a $10 air conditioner that should be able to cool a large room nicely. So, I said 'what the hey!'
For the project, you need:
- A Five Gallon Bucket
- A Drill with a 3 inch Circle Bit
- 3 PVC pipe sections, 3 inches in diameter and 6-8 inches long (you can get pre-cut ones or cut your own)
- An Exacto Knife
- A mall Fan
- Styrofoam liner (Home Depot and other hardware stores have them. . .they're also called styrofoam bait buckets)
- A Gallon Jug of Solid Ice (cleaned milk jugs work well for this)
- Drill three holes about halfway up the side of your bucket.
- Insert your styrofoam liner and drill through your bucket holes and through the styrofoam
- Drill (or cut with an exacto knife) a hole in your lid that is as big as it can be without your fan face falling through. Try to make your hole about a quarter inch smaller than the fan face
- Insert your pvc pipe sections through your bucket and through the liner
- If it's too tight, carefully shave little bits off of the inside of the cutouts until your pvc sections fit snugly inside the holes.
- Place a gallon jug of frozen water inside the bucket
- Replace the lid
- Set the fan in the hole, facing into the bucket and plug in
Theoretically, the fan will blow air over the ice, which will significantly cool the air and come out your little pvc pipes into your room.
I am not sure whether we have hot ice up here in the Sierras, or if the heat was just too much for the buckets were just too feeble against the room and it's high ceilings, but we did not receive any benefit at all from this experiment. We made three of them, had them all on in one room, and the temp did not go down one degree.
My seven year old suggested that maybe the temperature was going up, but the bucket a/c's were keeping the temp steady (he's ever the optimist!!), but I don't think that was the case. We tried them even when the outside temp was going down at dusk and still no luck.
So, it was an interesting and easy project, but not one I'd recommend.
