A whole house fan is an awesome add on to your home when it comes to cooling your house. Whole house fans are installed in either your attic or your roof and work by pulling air into your home through any open windows and making sure it leaves through your attic. It basically cools your home by bringing in cool air while taking the hot air out.
How do Whole House Fans Work?
A whole house fan works by creating negative pressure. What does this mean when it comes time to cool down your home? Your whole house fan will pull air through open windows, which will fill the room with fresh, cool, outside air.
This will make the negative pressure in your house build which will create positive pressure in your attic. When the pressure begins to build in your attic, it will release by pushing air out of soffits in your eaves or any other vents you have in your attic.
What this means for your home is there will be a cooling effect felt throughout. If you have rooms where you leave the windows open, that is where you will be able to feel your whole house fan’s effect the most.

There are plenty of benefits when it comes to purchasing a whole house fan. For starters, they work quickly to cool off your home.

Plus, since they use fresh air to cool your home, they will assist in taking out any odors from your house to make sure it smells as clean as possible.
And finally, if whole house fans are installed correctly, they will run quietly and last you a good long while!

Frequently Asked Questions About Whole House Fans
Are whole house fans loud?
The short answer is no, but there are several things that can go wrong which can cause them to get noisy. Most fans that are sold in the big box stores are usually the noisiest. They usually are the most poorly made. A super cheap whole house fan will only cost you more money and headaches than what you want.
Can I put a whole house fan in my attic?
A lot of attics are not ventilated the right way for whole house fans to work quietly. If air cannot exit the attic fast enough, the air left in the attic will cause back pressure against the fan, causing it to make more noise when it is running.
If you are able to get on top of all these problems, a well-made whole house fan will run as quietly as possible (46 to 52 decibels on high speed) and you will not have to worry about replacing it because it will last you 40 to 60+ years!
If your whole house fan is running right and being quiet, that means you can have a conversation standing right under the fan, and you will be able to whisper standing right underneath your whole house fan while it is operating at low speed.
Why is my whole house fan making noise?
The biggest culprit to a noisy whole house fan is either improper installation or it is cheaply made. Combine those two things and you will get a noisy fan.
Avoiding these two things are key and that is why it is wise to always reach out for help if you don’t know how to install a whole house fan. The last thing you want is to spend money on a fan, install it incorrectly, and then have to pay someone to come in and redo everything.
