Does a Whole House Fan Work in Every Season?

Most of us only use our whole house fan while running the A/C as the summer heats up, but did you know you could use it all year-round? Using a whole house fan can help you save money on your electricity bill and provide a comfortable and consistent environment in your home. Here’s why you may want to consider using your whole house fan, in any season.

What is a whole house fan, and how does it work?

Whole house fans are a great way to circulate cool air throughout your home. They’re easy to install and can be used in any season of the year.

How do whole house fans work?

Whole house fans are installed in your attic and have blades that rotate as they pull air into the fan through vents on the roof. The fan then sucks cool air into every room in your home, which reduces the need for air conditioning.

The cool air is distributed evenly, so you also don’t have to turn on ceiling fans or window units. The great thing about this is that it saves energy and money.

How to Use a Whole House Fan in the Summer

Whole house fans are a popular and cost-effective way to cool your home during summer without using your A/C.


Use During the Night to Naturally Cool your Home and Lower Energy Bills

Whole house fans help reduce energy usage by removing hot air from inside the home and replacing it with fresh air from outside. This lowers the temperature inside your home, which can help reduce overall utility bills.

Whole house fans are most effective when used at night when it’s cooler outside than inside. If installed correctly, they are generally less noisy than air conditioners. So, you don’t have to worry about them disturbing your sleep if you have them running all night long.

A whole house fan is designed to move air throughout the entire house, meaning it will help circulate cool air through your bedroom. This can help lower your home’s overall temperature and make it more comfortable for sleeping at night.

How to Use a Whole House Fan in the Winter

If you have a whole house fan, it is not just something you can use during the summertime. It can help keep your home comfortable during winter too.

Get Rid of Stale Winter Air

Whole house fans are an ideal solution for homes with poor airflow and stuffy conditions that tend to worsen during the winter. They can help improve indoor air quality by drawing in fresh air from the outside and pushing out stale air from inside your home.

In addition, if you have allergies or any other respiratory problems, whole house fans can help relieve symptoms such as irritation, sneezing, and runny noses.

Whole house fans also reduce can dust mites by removing humid air from inside your home.

Reduces Moisture Buildup Inside

Whole house fans are a great way to reduce moisture buildup inside your home. However, over time, the humidity in your home can lead to mold and mildew growth. This is not only unsightly, but it can also cause health problems for you and your family.

Whole house fans are designed to draw moist air out of your home. They move air through your house rapidly, drying out the air and removing excess humidity from your home quickly.

Vent Cooking Smells

The kitchen is one of the most difficult areas to keep smelling fresh and clean. The heat and steam from cooking can create a lot of unpleasant odors in your home. And if you don’t have an exhaust fan above your stovetop, those smells can get pretty strong.

If there are odors in one room or area of your home, whole house fans can help get rid of them with the extra ventilation.

Extra Operating Tips

When using a whole house fan, you should keep the following safety tips in mind.

Close the Fireplace Flue when Using a Whole House Fan

When you use a whole house fan, close the fireplace flue to prevent soot and ash from entering your home. If you have a wood-burning fireplace, it’s best to close the flue before turning on the fan. When the fan runs, it will draw in any smoke or soot present in your home.

Moreover, if you don’t close the flue, ash and soot could get sucked into your ductwork. This is bad news for your indoor air quality and your health.

Don’t Use Your Whole House Fan When the Humidity is High

You don’t want to use your whole house fan when you have high humidity.


Because it pulls in humid air from outside and puts it back into your home. The result is more moisture without any cooling effects. Extra humidity can lead to mold and mildew growth in your home.
