Tamarack Technologies HV1000-DB Whole House Fan

This unit comes with R38 Insulated doors

Homeowners can now quietly and efficiently reduce the indoor air temperature of their home, while improving air quality with the Tamarack Technologies HV1000 series of Whole House Fans. When the outside temp. drops below the indoor temperature, the HV1000 will draw cooler outside air, into the home. The hot air is drawn thorough the fan and up and out of the attic through existing attic and roof vents.
 

Here Is What A Few Of Our HV1000DB Customers Tell Us: 

Just wanted to let you know how much I love the HV1000DB. All week people have complained of the high temperatures and how miserable they are.  I have run the fan for 45 minutes early in the morning then I closed up the house and go to work.  Although daytime temperatures have been around 100 degrees all week (and it hasn't cooled down much at night) my house is comfortable inside. After a week of high temperatures it was 75 degrees inside this morning and no air conditioner. Anne Peramba, Conway, MA
