Thermal Mass Cooling

Free Cooling with Fans That Cool the Air

As we say goodbye to the frigid temperatures of winter and eagerly anticipate the warmth spring and summer bring, we also need to turn on the AC and resent the higher electric bills that come with them.

With every downward adjustment of our thermostat, our HVAC must work harder and harder to keep our air cool, ballooning our energy usage and the costs associated with it.

Luckily for us, there’s a better way to cool our home. So, what’s the remedy for lowering electric bills while maintaining a comfortable indoor ecosystem? Free cooling, of course.

What is Free Cooling?

Free Cooling, referred to as Thermal Mass Cooling, is the process of replacing the warm, stale inside air with cool, fresh outside air. Simply put, by drawing in the cool nighttime air from the outdoors, a whole house fan precools the house overnight to reduce AC usage throughout the day.

This way, rather than using their AC units, homeowners can open a few windows and engage their whole house fan in the evening. As the fan runs throughout the night and early morning, more and more heat is pulled from the home’s mass (walls, flooring, furniture, etc.) and released through the attic, which cools the house and everything in it. In the morning, homeowners simply switch off the fan, close their windows, and enjoy the precooled air, only needing to use their HVAC units when they want to make further adjustments for comfort.

A whole house fan increases fresh air ventilation while enhancing indoor air quality throughout the home, making them an excellent way to reduce energy usage and gain significant cost savings. According to the U.S. Department of Energy, whole house fans are a simple and inexpensive way to cool a house, provide excellent ventilation, lower indoor temperatures, and improve evaporative cooling.

In addition, operating a whole house fan costs only a fraction of the price of running central air conditioning, uses only a quarter of the power an HVAC unit, and is eligible for many state and local energy credits, discounts, and other incentives.
