Why are whole house fans so popular in So. Cal.?
It's due to the fact that California has an arid desert climate. If you read my pros and cons article about how whole house fans do not work well in humid climates then you would quickly realize that So. Cal. is pretty much the perfect location for whole house fans to work optimally. In fact Quiet Cool Manufacturing was founded in Temecula California and is one of the largest whole house manufacturers.
When you live in Temecula, Murrieta, Menifee or Riverside county you realize very quickly that we don't get much humidity which although unfortunate is perfect conditions for whole house fans.
Fallbrook, Bonsal and De Luz have a little more humidity but are still perfectly suited for whole house fans.
I personally lived in Rainbow California for 14 years and had a whole house fan virtually eliminate our cooling costs except for the hottest days of the year.
In the hotter, dryer inland empire whole house fans work even better in the evenings and early mornings.
Even though Orange county, Los Angeles and San Diego are near the ocean they still fall under a the south cost desert climate conditions and are ideal for whole fans as well.
The real trick to dialing in your savings lies in how well you use your whole house fan. Once you understand that your desired comfort level in the summer is directly linked to how much you run your AC you can begin to use your whole house fan more and more. Hot Tip: Get a wireless weather station like this one from Amazon so you can monitor outside temperatures. Once you know its cooler outside than it is inside your home which typically happens just after sunset you can turn off your HVAC system and turn on your whole house fan. The other tip is to flip it on first thing in the morning before the sun heats up the outside air temperature. This also gives your Cooling system a break which can save thousands on HVAC repairs in the long run.
