What is Free Cooling?
Free Cooling is another way of saying Thermal Mass Cooling when speaking about whole house fans. Free Cooling is the process of replacing the warm, stale inside the home with cool, fresh outside air. The process is simple. A whole house fan precools the house overnight to reduce AC usage throughout the day by drawing in the cool nighttime air from outdoors.
Save On AC Costs
Instead of using air conditioning, you can open a few windows and turn on your whole house fan in the evening. As the cooling fan runs throughout the night and early morning, built up heat inside the home is pulled and released into the attic. This cools the house and everything in it. In the morning, simply switch off the fan, close your windows, and enjoy the precooled air. This allows you to use air conditioning less and save on air conditioning costs.
