WiFi HV1000 R38 Whole House Fan


Introducing the NEW WiFi HV1000!
This powerful and energy efficient fan circulates up to 1000 cubic feet of air per minute for just pennies a day. Now compatible with Amazon and Google smart home devices for convenient voice command operation.



The HV1000R38 WiFi whole house fan will efficiently cool your entire home when the outdoor air is cooler than your indoor air. This wifi whole house fan mounts in the attic and works by pushing out hot, stuffy air through attic vents or gables while pulling cool, fresh air in through open windows.

Like all of our HV Series whole house fans, the WiFi HV1000R38 offers a unique design that is 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 its many benefits, installing WiFi HV1000R38 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. Tamarack whole house fans improve air quality by providing a quick air exchange throughout the whole home. Your family will breathe easier and enjoy a healthier, more comfortable home.
