Whole House Fan FAQ’s

Where should a whole house fan be installed?

A whole house fan is typically installed in the ceiling of a central hallway or in the ceiling of a room near the center of the house, such as a living room or dining room. The idea is to have the fan in a central location that allows it to pull air through open windows and exhaust it through the attic or roof vents, creating a flow of cool, fresh air throughout the house.

Is there an independent agency that reviews whole house fans?

We have found websites that claim to provide whole house fan reviews and/or whole house fan ratings; however, they are typically assoicated with the company that makes the whole house fan they are reviewing.

What is the Warranty?

Centric Air warrants the whole house fan and motor for 15 years from the original date of purchase against defects in material and workmanship under use as instructed by the user’s manual. All other components have a one year warranty. Customer satisfaction is our first priority. Although problems are extremely rare, we will do whatever is necessary to make sure the customer is happy with the product.

What are my payment options?

We accept Visa, Discover and Master Card.

Can I Use My Smart Phone To Control My Whole House Fan

Many of our clients use third party Smart Plugs for WeMo, Amazon, Google, etc. to control their Centric Air whole house fan. The unique benefit of a Centric Air whole house fan is that they are designed to plug into a standard wall outlet. However, Centric Air systems with our Cold Climate Dampers are NOT compatible with Smart Plugs.

What is the difference between a whole house fan and an attic fan?

A whole house fan is a primary cooling device that can significantly reduce or even eliminate the need for air conditioning. Attic Fans are smaller fans mounted on the roof or gable of your home. They work on a thermostat and help hot air escape from the attic but have no direct impact on your living environment.

Should I purchase a whole house fan even though I have air conditioning?

Absolutely! The reason being is that extremely hot air gets trapped in your attic during hot summer days. Through the late afternoon and evening, air conditioning has the chore of battling this heat that is radiating into the home. Because hot air within the home rises to the highest levels and cool air sinks to the lowest levels, air conditioning is fighting a losing battle. Customers relying on A/C alone find that they end up with an extremely hot upper level and extremely cold lower level.

What size whole house fan do I need?

CentricAir recommends that clients consider purchasing the largest whole house fan that their home has the attic ventilation for. It’s very likely for example that a 2200 sq. ft. home will have sufficient attic ventilation for our CentricAir 2.7 model which requires about 3.25 sq. ft. of net free attic ventilation. However, if this same size home has enough attic ventilation for our CentricAir 3.4 system which is designed for homes with 4.0 sq. ft. of net free attic ventilation, this may be worth considering since it’s only slightly more expensive and will cool your home even faster. We do not, however, recommend adding additional roof ventilation just to go with a large whole house fan.

How long does it take to complete a whole house fan installation?

Most jobs are completed in approximately 90 minutes as long as you have an electrical outlet within the vicinity of the whole house fan.

How much does a whole house fan cost to install if I choose not to install myself?

This can vary widely depending on what part of the country you are in. In our experience, most installers charge about 4 to 5 hours which includes travel to the home and installation

How much does a whole house fan cost to operate?

As little as $0.02 to $0.07 per hour to operate, depending on the model you purchase.

How many windows do I need to leave open? Which ones? How Far?

Opening two or more windows half way or more is recommended. Basically you should make it easy for the fan 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 entire 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.

How loud are whole house fans?

The German engineered and manufactured fans that we use in our whole house fans are acoustically designed and precision balanced which makes for an exceptionally quiet and smooth operation. However, we took it one step further. Rather than use standard ductwork with plastic lining, we use sound absorbing acoustical ductwork which absorbs both sound and vibration better than standard ducting.

Can I use a thermostat to control my whole house fan?

We do not recommend using a thermostat. In order for the whole house fan to work properly the windows in the home must be open. If your fan turns on automatically without the windows being opened, it can pull air from your fireplace for example causing soot to stain your carpet or furniture. Since the cooling happens immediately, there is really no reason to run the whole house fan when you aren’t home.

Why are CentricAir the best whole house fans?

While other whole house fan companies typically build their products from the same cheap generic parts available to anyone, we make it a point to be uniquely better. To do that, we spent years researching and testing all types of fan motors. We ultimately found that the German Engineered and Manufactured fans significantly out performed any other whole house fan motor on the market. Although these German Engineered fans are more expensive, the performance and quality is far superior than any other fan available.

Why are CentricAir whole house fans easy to install?

As long the joists in your attic are typical of most homes (16″ or 24″on-center) there is no framing required. You simply cut a hole in the ceiling (or vertical wall), install the mounting brackets, damper box and ceiling diffuser with a few screws. Then connect the ductwork and support the fan assembly to the rafters in the attic. Finally, plug the whole house fan into a standard electrical outlet and it’s installed! Installation is typically completed in about 90 minutes if theirs an electrical outlet near by.

What if my remote control stops working or I lose it?

One of the unique benefits of a CentricAir whole house fan is the fact that we designed the receiver for the remote control, to be 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 want to make sure that it is easy for our customers to replace the remote control incase there is ever a need.
