Frequently Asked Questions

How Long Does a Whole House fan take to cool down my home?

The air in your home will be exchanged approximately every 8 minutes by the Zephyr Blade’s six steel aerodynamic, balanced blades that are designed to remove the hot air quickly and quietly. Just flip the switch on for 30 to 60 minutes at the beginning and end of each day. This will enable you to run your air conditioning fewer hours and enjoy comfortable living for less!

Is the Whole House Fan noisy?

NO! – Our fan is designed exclusively by us and to our standards. Unlike fans sold in the hardware stores that have only 4 aluminum blades and sound like a World War II war plane, our Whole House Fan Zephyr Blade Design, runs quietly enough to sleep with it on. Many of our happy customers leave it running all night and enjoy the cool, quiet “breeze” that it generates.

How much does it cost to operate?

Our Whole House Fan is very energy efficient – It can run for 12 hours a night for the same cost as your porch light (approximately 35¢ per night)! Most of our customers spend an average of only 85¢ a day to operate our Whole House Fan. (This is based on running it for 30-60 minutes in the morning and then again in the evening when the outside temperatures cool down). By comparison it costs an average of 85¢ to run your air conditioner for only 45 minutes. Most utility companies say that by properly using a whole house fan, many people can reduce their air conditioning bill by more than half!  At night, your Whole House Fan runs the same as a 200 watt porch light, and in the day, it runs about the same as a coffee maker.

Does it require maintenance?

No, our fans do not require any maintenance; they are maintenance free.

What other benefits are there?

If you cook fish, pork or burn toast, it quickly pulls out smells, and keeps your home fresh year round.

What about 2 story homes?

We love two story homes.  Our 30″ or 36″ Whole House Fan is designed to move air from both the lower first story as well as the 2nd upstairs floor.  People wonder how they ever lived without their Whole House Fan.

Why are some house fans lacking power?

Most whole house fan blades are too small or are inadequate.  The Zephyr Blade changed everything!
