HV1600 R38 Whole House Fan


This powerful, remote-operated whole house fan improves indoor air quality and quickly cools the whole home using fresh, outside air. It features unique R38-insulated doors that self-seal when the fan is not in use.




The HV1600 R38 whole house fan is a powerful fan that mounts in the attic and runs for pennies a day compared to AC. It rapidly cools your entire home whenever the outdoor air is cooler than the air inside your home. It does this by pushing out hot, stuffy air through attic vents or gables while pulling cool, fresh air in through open windows.

Like all our HV Series whole house fans, the HV1600 R38 features a unique design unlike any other brand on the market. Its insulted doors seal automatically when the fan is not in use, keeping cool air from making its way into your attic between uses. Additionally, the insulated doors prevent heat loss through the attic during the cooler months.

Among their many benefits, installing a HV1600 R38 whole house fan saves energy and dramatically reduces air conditioning costs. The money and energy saved using a whole house fan is a great advantage, but the health benefits are even greater. The HV1600 R38 provides a quick air exchange throughout the whole home, and this substantially improves the air quality. As a result, your family can breathe easier and stay healthier.

The HV1600 has been featured twice on the popular home improvement show Ask This Old House. A clip of the episode can be viewed here.
