Benefit of Running a Whole House Fan in the Winter

A whole house fan can improve your home's ventilation throughout the year by removing indoor stale air while allowing the circulation of clean fresh air inside the house.

Why do you need whole house fans in the winter?
Although whole house fans are considered summer appliances, there are still some benefits you can enjoy from them during the winter months.

Improve air circulation:
Your home can experience air ventilation issues during the winter months with the doors and windows staying shut for most of the time. Using whole house fans during the winter can help remove stale indoor air while bringing in fresh air to your home, improving air circulation.

Improve indoor air quality:
The stale indoor air in your winter home can be full of air pollutants including dust, pet dander, and mold spores. Running a whole house fan can reduce the concentration of stagnant air pollutants helping you breathe easier.

Reduce indoor moisture buildup:
Lack of air circulation can cause moisture to build up in your home during the winter. Moisture arising from seepage through the foundation and leaky pipes gets trapped indoors when the house is sealed tight leading to an increase in molds and pests.

Using a whole house fan can improve ventilation reducing the moisture buildup.

Help vent foul odors:
A sealed winter home can cause a buildup of annoying foul odors. Using a whole house fan can improve house ventilation bringing in fresh air.

Help prevent ice damming and attic rain:
Ice damming and attic rains are common phenomena faced by people living in areas that face harsh winters. Ice damming occurs when a buildup of snow in your roof melts causing water to seep through the roof edges, creating ice dams.

Attic rains occur when the humid indoor air condenses after coming in contact with the freezing roof and forms moisture spots and stains on the home ceiling.

Both conditions can damage your roof. A whole house fan can prevent them, helping you avoid extra roof maintenance.

Winterizing Your whole House Fan
Winterizing your whole house fans can ensure proper home insulation. Most fans come with motorized and insulated doors that automatically close when turned off. You can also use a winterized insert to further insulate a Quiet Cool Whole House Fan.

Otherwise, you must seal the fans to avoid cold drafty air in your home.

Whole house fans can be insulated with a solid cover that is attached and secure to improve your home’s energy efficiency.

The key point is that whole house fans aren’t only beneficial in the warm months, they offer the above benefits in the colder weather too.
