Why Should I Invest in a QuietCool Whole House Fan?
Cool Faster
Your air-conditioning system may take an hour or two to drop the temperature 10° in your home. Under certain conditions, a QuietCool Whole House Fan can do it in mere minutes.
Reduce Electricity Costs
A QuietCool Whole House Fan uses a fraction of the energy required by air-conditioning systems. Using one or more to cool your home can save enormous amounts of electricity.
Return on Investment
A QuietCool Whole House fan is one of the few home improvements that pays for itself over time. Customers can save hundreds of dollars a year in energy costs when it is used effectively.
Fresh Air
Air-conditioning systems require that all your windows be closed and the air be constantly recycled. A QuietCool Whole House Fan does the opposite! When it’s cool outside, you open your widows and the massive fan pulls enormous volumes of cool, fresh air inside.
Cool Your Attic
Most houses are designed with no thought for their environment. Walls and ceilings are insulated but our attics are all passive solar ovens! Attic temperatures on a hot day can easily hit 140°F. The cool air your QuietCool Whole House Fan pulls into the house is pushed into the attic where it displaces all that hot air within minutes. This reduces the invisible heat load leaking down into the house from the attic.
Save the Planet
Less than 22% of electricity used in California comes from renewable resources. The balance includes generation using coal and nuclear fuel. When you reduce your electricity consumption, you are reducing pollution from dirty energy sources and helping save the planet… One Fan at a Time!
