I had a couple of requests to show this neat trick I have of keeping the house cool.
first, some theory.
Everywhere the sun hits, it gets hot, which is why closing your blinds to keep the sun out is helpful. You’ll notice the wall still getting really hot, though, because the sun is still hitting it.
The same heat buildup is happening in your attic, although you might not realize it. The heat builds up in the attic, and especially if you live in an older house with poor insulation like I do, the heat transfers down through the ceiling into the house, making things really hot.
So if you could push air into the attic, it could cool the attic, which would keep the house from getting too hot. If you open a window on the cool side of the house, you can help cool things even further.
The hot air leaves the attic via vents under the eavestroughs or on the roof. This happens normally, but you can help force airflow to go faster using this trick.
So where can you find a place to push air into the attic? Well, in my house, it’s right in the hallway. sometimes attic access will be in hallway, or bedroom, or closet; if you don’t know where yours is, you’ll have to look around, but you probably have one.
It’s usually pretty easy to get into the attic; just get a stepladder and push the board up.
Warning; if you do this on a hot day, it’ll be crazy hot in the attic.
Next you need a box fan. These are pretty cheap from Walmart or the hardware store.
Mine comes with a switch with 3 different settings.
However, if you were to try fit the box fan into the space, you’ll likely find that it doesn’t work; the space is too large for the box fan.
What I had to do is take some scraps of wood and build an inset. It’s pretty flimsy; just held together with staples; but it doesn’t need to carry a lot of weight. I also put a bit of weather stripping on it to keep the air from escaping too much.
So you put the insert in, and then the fan. Remember that you can rotate it to get it to fit the now-tight space.
You’ll need to find a plug for the fan. Take a look around in your attic; often there;s an outlet, and you can use a short extension cord to get the power to the fan.
And that’s all there’s to it. in the coming weeks, if there’s a heat wave coming, just climb on a chair or stepstool, turn on the fan, and start cooling down your attic!
Although this approach isn’t as effective as Air Conditioning, it’s a fraction of the cost and uses way less electricity.
