Understanding the Technology: How Insulated Whole House Fans Work
If you live in a region with a moderate climate, try using an insulated whole house fan to cool your home cost-effectively and reduce your reliance on air conditioning.
But what exactly makes a whole house fan effective for most cooling needs? And is it really a smart investment for your home? This blog has the answers — from explaining how these fans work down to their many benefits. We will also recommend some tried-and-tested products to take the guesswork out of choosing the right fan for your needs.
How whole house fans cool your home
Insulated whole house fans are usually installed in the attic. And no — you won’t have to worry about these fans disrupting conversations or ruining your sleep because there are quiet models available. Quiet Cool makes some of the best options in the market today, featuring one-of-a-kind insulated ducting materials that reduce operational noise.
An insulated whole house fan works by drawing cool outdoor air through your home while simultaneously pulling attic air into the fan for cooling. This dual-cooling system is most effective when outdoor temperatures are lower, so be sure to open all windows and turn on the fan during cooler times of the day (such as early morning or late evening). This allows for better airflow and more efficient cooling at a fraction of the cost of air conditioning.
How is it different from attic fans?
A whole house fan doesn’t just cool your home. It works like an exhaust system to pull hot air from your living spaces. Given how it works, it’s often confused with an attic fan, but these systems actually have different goals.
An insulated whole house fan pulls hot air into the attic. Positive pressure forces this hot air out through attic vents or gables, while negative pressure in your living spaces draws cool air in through open windows, creating a refreshing breeze. This is how a whole house fan removes heat while simultaneously cooling your home.
Attic fans, in contrast, only remove hot air from the attic. They don’t provide cooling to the living areas of your home. That said, they still help your home stay cool, especially during the summer months. This is because a cooler attic reduces the workload on your air conditioner, leading to more efficient cooling and energy savings.
While insulated whole-house fans are typically installed in attics, they can also be installed on the highest ceiling of your home if you don't have an attic. This will still draw in cooler outdoor air and exhaust hot air, cooling your home.
Economical and practical cooling
A whole house fan can provide cost-effective cooling for homes in areas with mild and temperate climates. It may even eliminate the need for central whole-house air conditioning altogether.
Did you know that it costs so much less to run these fans than air conditioners? Home improvement experts estimate that whole house fans can operate at one-tenth the cost of air conditioning and that you could potentially reduce your energy bills by 80% by using them. Many people report that they rely on their air conditioners 50-90% less once they install a whole house fan.
That said, it’s important to get the right fan size for your home. You also need to choose an insulated whole house fan from a reputable brand like QuietCool. Standard-sized whole-house fans usually have a diameter of 24 to 36 inches, but you can adjust the size to meet your living space’s dimensions.
Effective cooling and better indoor quality with the latest whole house fans
At Whole House Fan, we carry the latest models from QuietCool. They substantially reduce indoor temperatures by pulling cool outdoor air inside the home. Moreover, they eliminate the warm, stale air indoors by drawing it into the attic and pushing it out of the building through the roof vents. This results in quiet and efficient cooling for the whole house.
An insulated whole house fan can significantly lower the temperature in your living spaces while providing energy-efficient cooling. We recommend turning it on in the evening or morning when the outside air is fresher and cooler. Just keep the windows open so the fan can draw cooler air inside the home more effectively.
Are you concerned about stale indoor air affecting your health? By using a whole house fan, you can eliminate poor-quality air with cool, fresh, and lean outdoor air. This will greatly improve the indoor air quality of your home, allowing you to breathe easily.
Quiet performance
One of the best features of Quietcool whole house fans is the insulated ducting material. It helps reduce operational noise by dampening sound transmission, so you can watch TV, enjoy conversations, and rest peacefully without disruptions. Unlike traditional attic fans and ceiling-mounted ventilation systems that tend to make a lot of noise, QuietCool ensures whisper-quiet performance without disruptive noise or vibrations.
More control over cooling
Quiet Cool’s latest whole house fan models come with various features, so you will surely find a model that suits your lifestyle and cooling requirements. A powerful single unit can cool multiple rooms. If you’re looking for a budget-friendly or smaller unit, we can recommend an insulated whole house fan that offers zoned cooling for select areas like bedrooms.
Environmentally friendly cooling
Air conditioning cannot beat a whole house fan when it comes to energy savings and environmental performance. We carry the QuietCool Energy Saver series, which is top-rated by the California Energy Commission based on the CFM/watts.
