QC ES-2000
Compare & Review Whole House Fans When you review and compare products listed in the California Appliances Database which contains listings for all appliances currently listed on the California Energy Commission website as meeting currently applicable efficiency standards, you will see that QuieCool Fans are rank at the top in energy efficiency compared to many of the brands.

In addition to comparing the energy efficiency rating, it is also important to consider the fans air flow (CFM) and noise level. Many of the brands listed are mounted directly to the ceiling or use a belt drive motor and will not be as quiet as the ducted QuieCool Fans.

The whole house fans listed here either meet federal efficiency standards or, where there are no federal efficiency standards, meet California's appliance efficiency standards.

Energy Efficiency

The below chart shows the energy efficiency ratings of whole house fans sold on the market today. Energy consumption is one of the major factors that should be considered when selecting a whole house fan. The higher the "Air Flow Efficiency (CFM/Watts)" rating, the better (also keep in mind the noise level of the fans. Fans that mount directly on the ceiling may be much louder than a ducted whole house fan like the QuieCools.)

QuieCool fans hold the top 6 spots on the CEC Efficiency Database for ALL fans, and the top 12 out of 14 spots for all residential fans tested at an airflow of 5,000 CFM or under.

When comparing Air Flow (CFM), Quiet Operation, and Air Flow Energy Efficiency, QuieCool Whole House Fans Are A Top Choice For Home Owners!
