Field Controls offers two types of free cooling systems: VentCool™ Whole House Fans and VentCool™ Automated Free Cooling Systems. A Free Cooling system replaces warm/stale inside air with cool/fresh outdoor air. This typically occurs during the evening and overnight when temperatures outside are cooler.
The benefits of free cooling begin with dramatic energy savings. Free Cooling systems use up to 90% less energy than compressor-based air conditioning units. As the cooler air circulates through the home, it cools the structure and everything in it. With thermal mass cooling, the air conditioning is not needed until later in the day. This translates into less use of the AC system and significant cost savings.
The Department of Energy (DOE) reports that whole house Free Cooling systems are the most cost effective way to cool your home. Many state and local codes provide energy credits, discounts, or other incentives for free cooling systems. VentCool models qualify for California's Title 24 Energy Credits.
Think efficient, quiet, powerful, and simple. VentCool Whole House Fans are ultra-quiet whole house fans that cool naturally by replacing hot indoor air with cool outdoor air. VentCool Whole House Fans use about one tenth the electricity of a typical air conditioner, providing a welcome reduction in utility costs.
Think efficient, secure, automatic and dust free. VentCool Automated Free Cooling Systems (AFCS) integrate with the whole house HVAC fan and ductwork and are designed to bring in fresh air without opening a window or door. Fully automated controls can be monitored and controlled remotely from a PC, smartphone or tablet. The ability to control and maintain the highest quality of indoor air and energy efficiency levels have never been simpler.
