Frequently Asked Questions About Whole House Fans
Q. Is there an independent agency that reviews whole house fans?
A: There are websites that claim to provide independent whole house fan reviews; however, we found that they are typically associated with the whole house fan company that builds the whole house fans they are reviewing.
Q. What is the warranty on your whole house fans?
A: For our CentricAir whole house fans, Comfort Cool guarantees the fan motor for 15 years from the date of purchase against defects or failures under use as instructed in the user's manual. All the other components such as switches have a one-year parts warranty. Customer satisfaction is our first priority.

Q. Can I Use My Smart Phone To Control My Whole House Fan?
A: Many of our clients use third party Smart Plugs for WeMo, Amazon, Google, etc. to control their Comfort Cool whole house fan. The unique benefit of a Comfort Cool whole house fan is that they are designed to plug into a standard wall outlet. However, Comfort Cool systems with our Cold Climate Dampers are NOT compatible with Smart Plugs.
Q. Do I need a whole house fan even though I have air conditioning?
A: Yes! The reason is because during hot summer days, extremely hot air gets trapped in your attic. Throughout the late afternoon and into the evening, air conditioning has the job of battling the heat that is radiating into the house.
Because cold air falls to the lower level and hot air within the home rises to the highest level, air conditioning is fighting a losing battle. Customers relying on air conditioning alone often find that they end up with a cold lower level and hot upper level.
Q. What is a whole house fan?
A: A whole house fan is a type of fan, or exhaust system that removes hot air from the attic and living space of the home. It is sometimes confused with an attic fan which only exhausts hot air from the attic to the outside through a gable vent or opening in the roof at a low velocity.
Q. Is a whole house fan different than an attic fan?
A: A whole house fan can be used to cool your entire Rancho Santa Margarita home including the attic and can significantly reduce and in some instances eliminate the need for air conditioning.
Attic Fans are smaller fans that are mounted on the gable or roof of your house. They typically work on a thermostat that's installed in the attic and help remove hot air from the attic but do not have a significant impact on the temperature inside the home.
Q. How expensive are whole house fans to run?
A: Depending on where you live and what system you purchase, the cost to operate one of our whole house fans can be as little as $0.02 to $0.08 per hour to operate.
Q. What size whole house fan do I need?
A: We recommend to consider purchasing the largest whole house fan that their home has the attic or roof ventilation for. The bigger and more powerful the system, the faster the home will cool down.
In order to determine how much attic or roof ventilation is required for each Comfort Cool whole house fan, please call us and we'll gladly tell you how you can determine how many square feet of attic ventilation you have. Our professional advice is always free.
Q. Are whole house fans noisy?
A: The modern motor fans in our systems are precision balanced and acoustically designed to allow for an extremely smooth and quiet operation. However, we took it even further. Rather than use typical air conditioning ducting with plastic lining, we use sound absorbing (Quiet Flex) ductwork which absorbs vibration and sound much better than standard ductwork.
Q. How long does a whole house fan installation take?
A: Most Comfort Cool whole house fans are installed just a couple of hours. In certain circumstances installation may take a little longer, although that is very uncommon.
Q. How much attic ventilation do I need for my whole house fan?
A: Each of our Whole House Fans has a listed requirement for attic venting. See the Specification tab for the product you are interested in.
Q. Can I put the whole house fan on a thermostat so that it will turn on automatically?
A: Technically, yes, but we do not recommend this. In order for the home ventilation system to work correctly, windows need to be open. If your whole house fan turns on automatically and the windows are not open, it can pull air from your fireplace causing ash and soot to stain your furniture and carpet. Since the cooling effect occurs almost immediately, there is no reason to run your home ventilation system before you arrive home.
Q. How do whole house fans work?
A: A whole house fan works by pulling cool fresh air in through open windows or doors and exhausting the hot stale air out through attic and roof vents. Using a whole house fan to cool your home can substitute for an air conditioner most of the year in many climates. Video - How Whole House Fans Work.
Q. How many windows should I leave open and which ones?
A: Opening two or more windows half way or more is recommended. Basically you should make it easy for the home ventilation system to pull in air. As for which windows to open, for general cooling you want to open windows far away from the fan to provide airflow to the whole house.
Or, you can open windows in the areas you want cooled. For example, if the upstairs bedrooms are the warmest, then open the windows in those rooms only and close the down stairs windows.
Q. What if my wireless remote control stops working or I lose it?
A: A unique benefit of a Comfort Cool whole house fan is that the receiver for the remote control is separate from the whole house fan. As a result, the whole house fan plugs into the receiver and the receiver plugs into a standard electrical outlet. We wanted to make sure that it was easy for our clients to replace the remote control and receiver in case there was ever a need.
Q. What makes Comfort Cool whole house fans better than other whole house fans?
A: While most whole house fan companies build their whole house fans from the same cheap generic parts available to anyone; we wanted to make it a point to be distinctively better. To do that, we spent years testing and researching various types of fan motors.
We eventually found that the German Engineered fan motors significantly outperformed any other fan motor on the market. Although these German engineered motors are more expensive, the quality and performance is far superior to any other fan available.
