I have noticed that at times it is already quite warm outside but remains cold inside and also in a different season, still hot inside when it is cool outSo if I could efficently replace the inside air with the outside, I would need much less heating and coolingDuhThat's what it's aboutSo what are the pros and cons? How does the air get from the room to the attic? Is there a danger of sucking dust out of the walls into the room?
Whole house fan mounts in your ceiling and blows into the attic, drawing outside air through the windows which you leave openThe attic fan draws outside air into the attic and blows hot air out of your atticAttic fan can lower your AC cost in the summer, especially if your attic insulation is not the best and you have no shade trees to shade your roofWhole house fan will suck in all the smells and pollen from outside, but you can shut down the AC sooner on a hot evening if your area cools off fast at nightNo good for places like Phoenix where it stays hot all night in the city.
