We have two rooms in our house that never cool down. Even though we have central AC and there is a duct there, that area is always about 10-20 degrees warmer in the summer. (It’s colder back there during the winter but that is never quite as troublesome as at it being hotter.) That part of the house is an addition that didn’t get the same degree of insulation as the rest of our home.
Usually we have to keep those rooms shut off from the rest of the house in order to keep the AC from cycling on too often. When the AC unit switches on, the fan sucks in air from the house and draws the hot air from those rooms into the rest of the house, raising the temperature in the main area and causing the AC to have to run longer to bring the temperature of the rest of the house down the while hot air is still being sucked from those rooms….you see the vicious cycle there?
So we usually just keep those rooms shut during the summer. The problem is that those are my sons’ bedrooms. It ends up being too hot back there for them to sleep so they spend most of the summer sleeping in the living room. That’s a pain too. So what to do?
This year I decided to make a redneck air conditioner to put in their room. This little contraption is supposed to help take the edge off the heat for a fraction of the cost of running a window AC unit.
- Styrofoam cooler
- Small fan, 6 inches or so
- pvc elbow, this one is 1 1/2 inch
- sock or other piece of fabric
- pencil or pen to mark off the fan and elbow
- serrated knife
It was so fast and easy. Levi wanted to make this one since it was going in his room.
Place the fan and the elbow on the lid and trace them.
Cut out the openings for the fan and elbow.
Go easy. You don’t want to push too hard and crack your lid.
Now cut your sock to make a loop.
Stretch the loop and wrap it around the edge of your fan.
We needed a few sets of hands to get this on. It will help form a seal between the cooler and fan and prevent air loss.
Now get some plastic bottles from your recycling that you have filled with water and frozen and pack the cooler with them.
Levi said he could already feel a difference. So we put it in his room for a test run.
We left it for a while to run and later when we checked on it the room didn’t seem nearly as hot as it usually gets.
The space back there is pretty large so I can see making a couple of these to put back there. Maybe I’ll make one for each boy to place by their bed so that they can be comfortable enough to sleep in their own rooms.
What do you do to beat the heat?
