How Long Has This Form Of Home Cooling Been Used?  Before there was air conditioning, people used fans to cool their homes.  Whole house fans have been used in the United States for a very long time.  Within the last 15 years, fan designs and efficiencies have changed dramatically for the better.

Where Should I Install My Whole House Fan?  In the ceiling of your home between the attic and living space...Yes, over the years 1 or 2 customers have installed them on the roof of their homes!  The Ghost, HV1000, HV1450 and the HV1600 should all be installed in a central location. The Superfan can be installed anywhere in the attic because it is designed to be remotely mounted.  The TC-1000H is the only exterior mountable whole house fan.

Who Installs Whole House Fans?  In many cases, a licensed electrician, especially if there is wiring involved.  We recommend you get at least 3 installation quotes, from companies that are licensed and insured. 

Will Your Whole House Fans Affect The Blown-In Insulation In My Attic?   By virtue of design, our fans, will have a minimal impact on attic insulation.

When Should I Use My Fan?  Typically the evening and early morning hours.  When the outdoor temperature is cooler than inside your home. 

How Can I Maximize The Use Of My Fan?  Use a timer to run your fan(s), you will be able to gauge how long the fan needs to run before you can turn it off.  Once turned on the fan will automatically shut-off.  In the early morning hours, at the beginning of each day - run your fan.  Before it heats up outside, turn your fan off - and close the windows and blinds to your home.  If you set your air conditioner on a thermostat, set your thermostat to 78-80 degrees.  Because you pre-cooled your home, it will take longer for your home to heat up and start your air conditioner.

Can I Use A Whole House Fan During The Daytime?  Only if it is cooler outside.  Never run your fan when it is hot outside, it would be like turning your home into a giant convection oven.

Can I Use My Fan With Air Conditioning?  Not simultaneously, you would be sucking conditioned air out of your home.  When used as an air conditioning assist - you would run your whole house fan to quickly reduce the ambient air temperature inside you home and cool the structure.  When you do turn on your air conditioner (after shutting your windows and turning off the whole house fan),  it will work faster to cool your home.

How Long Will It Take For My House To Cool Down?  There are to many variables to give a specific time.  The size of your home, ceiling height, direction its facing, amount of windows, etc.  all different factors that need to be taken into account.  Every home is different.  The greatest cooling benefit will occur when temperatures are cooler outside.  The larger the difference in temperature the faster your home will cool down.

Can I Use My Whole House Fan On A Thermostat?  We do not recommend using a thermostat to control your fans operation. You need to open your windows before using the whole house fan. A thermostatically controlled fan has the potential to turn on all windows were closed.  

Can I Use A Timer With My Whole House Fan?  Absolutely.  For The HV Series Fans and The Ghost - any standard mechanical timer can be used.  Electronic and digital timers cannot be used on these fans.  The Superfan will accept virtually any style of timer - as long as it meets the proper amp rating.
 

Is It Necessary To Open All Windows In My Home When Operating A Whole House Fan?   The amount of windows opened should at a minimum be equal to the amount of Net Free Venting required for each fan.  For example, the HV1450 fan requires 2 sq. feet of net free venting, so you should open at least 2 sq. ft of window area to balance the flow of air into and out of your home.  You do not need to open every window in your home.  In fact, you can selectively open windows to direct the flow of cool air specific rooms or areas in your home.

Why Can’t The Fans Be Used With A Variable Speed Controller?  A variable speed controller, causes excessive motor whine - which creates more noise than is necessary.  The only model that can be used with a variable speed controller is the HV1450. The other fan motors are not built for a variable speed controller.
