Tamarack HV1000 R-38 Whole House Fan

Tamarack HV1000 R-38 Whole House Fan – Energy-Efficient Cooling for Your Home The Tamarack HV1000 R-38 Whole House Fan is the perfect solution for homeowners seeking quiet, energy-efficient cooling. Designed for homes up to 1,600 square feet, this powerful fan quickly circulates 1,000 CFM of air, replacing hot, stale indoor air with fresh outdoor air whenever temperatures drop. By using just 63 watts, this fan significantly reduces the need for air conditioning, cutting energy costs. How It Works Installing the HV1000 Whole House Fan is simple. Mount it in your attic floor between joists and secure the included return air grille from below. When the temperature outside cools in the evening, open your windows and turn on the fan. The self-sealing, insulated doors (R38 or R50) automatically open, allowing fresh air to flow through your home while hot air escapes through attic vents. In the morning, simply turn off the fan—the doors automatically close to prevent air loss, helping maintain comfortable indoor temperatures. Energy Savings & Improved Air Quality A Whole House Fan uses just 10% of the energy of a central AC system, saving you money while promoting natural ventilation. Unlike traditional air conditioning, which recirculates indoor air, this fan removes indoor pollutants, allergens, moisture, and odors, ensuring better air quality. Research shows that homeowners in California using a Whole House Fan lowered energy consumption and reduced reliance on AC.
