HOW TO SIZE AN ATTIC FAN:

A properly sized attic fan is very important to ensure the most effective and efficient ventilation of your attic.

We recommend sizing your attic fan at .5 CFM per square foot of attic space for every 2 feet of peak attic height. This formula gives a minimum of 15 complete air exchanges per hour.

This means for a 1500 SQFT attic with a peak attic height of 4 feet, you will need an attic fan that moves at least 1500 CFM. If the peak attic height is only 2 feet, you would need at least 750 CFM. If the peak attic height is 6 feet, you would need at least 2250 CFM, and so on.

This math formula will work every time, for any size attic, and as always the more airflow the better.

This sizing formula provides a minimum of 15 complete air exchanges per hour which is equivalent to the sizing formula we use for our whole house fans.

Note that this sizing formula is based on attic square footage, not the square footage of the home. While in some cases they may be the same value, such as with a single story home, multi-story homes will have a different attic square footage than the home.

If you need assistance with sizing an attic fan, use our Attic Fan System Builder below.

SMART ATTIC FANS

ROOF AND GABLE APPLICATIONS AVAILABLE

Smart attic fans are the newest revolution in the attic fan industry.

A smart attic fan features a built-in thermostat and/or humidistat that directly controls the motor speed based on the conditions in the attic. By self-adjusting to the attic conditions, the fan is able to maintain an optimum year-round attic climate while minimizing energy consumption.

In the summer months, a smart attic fan will prevent the attic from reaching scorching hot temperatures that, in turn, transfer into the living space below.

These smart fans typically feature a smartphone app that offers the ability to control all parameters of the fan from temperature settings, humidity settings, and it even allows you to see the current conditions in the attic.

Studies have even shown that a smart attic fan can keep your attic within 10 degrees of the outside temperature, even during the peak heat of the day.
Solar Fans

SOLAR ATTIC FANS

ROOF AND GABLE APPLICATIONS AVAILABLE

Solar Attic Fans are ideal for any homeowner who wants attic cooling but does not want to use any more electricity. This helps the homeowner save the maximum dollar amount on their electricity bill every month.

These fans operate solely by using solar power to push air from the attic vents, throughout the attic space, and back outside. Some solar attic fans come with an AC/DC Inverter, which allows you to run your fan throughout the day and night by switching from solar power to electricity automatically.

If you only want to use solar power, you can choose to have the inverter disconnected on install. Solar attic fans are ideal for any homeowner looking to keep the world green and their home cool and healthier.

TRADITIONAL ATTIC FANS

GABLE APPLICATIONS AVAILABLE

Traditional Attic Fans are what most homeowners have in their homes when it comes to attic fans. These fans push a lot of air, are powerful, and reliable. These fans often come with a thermostat and are single speed only typically that can be set to when you want your the fan to run and can push air at up to 2,000 CFM. These attic fans are typically less expensive and perfect for anyone who wants a cheap alternative to their high A/C costs.

SMART ATTIC FANS VS TRADITIONAL ATTIC FANS!

Homeowners! Here’s why QuietCool Smart Attic Fans are the best on the market. Traditional attic fans operate on a principle called reactive cooling, while our smart attic fans operate through proactive cooling. Let me explain. Traditional attic fans rely on a thermostat set at 120 degrees and only turn on when it reaches this temperature. By then, the attic is already extremely hot and will cause AC cycling. Quietcool Smart Attic Fans are the first and only multi speed attic fans. We set the low speed to activate at 80 degrees, Medium at 100 degrees and High at 110 degrees. This allows us to begin cooling the attic space proactively, keeping the attic within 5-10 degrees of the outside temperatures. The best part is your QuietCool Smart Attic Fan allows you to control and monitor the temperature and humidity from the convenience of your phone. It comes with a variety of customizable presets to make ventilating your attic space a breeze. It even has an ultra energy efficient ECM motor. When running on low and medium speed your fan is using the equivalent of a couple of LED light bulbs worth of energy. In comparison, traditional attic fans can use up to 10-20x more energy. Designed to be effective 24/7, 365, in any climate zone during any season. Stop cooling your home reactively and begin saving money through proactive cooling with a QuietCool Smart Attic Fan.

SOLAR ATTIC FANS VS TURBINE VENT

When it comes to comparing solar attic fans and turbine vents, there are a few key points to consider. Solar attic fans offer several advantages over turbine vents, primarily due to their ability to move significantly higher airflow.

Turbine vents often claim to move up to 300 CFM, but in reality, they typically only move around 10 to 30 CFM. On the other hand, solar attic fans can move up to 20 times more airflow, thanks to the use of a motor that actively forces air movement. This mechanical airflow allows for a much higher rate of air exchange in your attic, helping to keep it cooler.

The increased airflow provided by solar attic fans ensures that your attic stays within 5 to 10 degrees of the outside temperature. This level of temperature control is difficult to achieve with turbine vents alone. However, you can actually use both a turbine vent and a solar attic fan together for even better results. The fan will help pull air from the outside, passing it through the turbine vent and into the attic, creating a more effective ventilation system.

While both options can contribute to cooling and ventilating your attic, if you had to choose one, a solar attic fan is the more capable choice. Its ability to move a significantly higher amount of air, combined with the active air movement provided by the motor, makes it far more effective in maintaining attic temperature and ventilation.

ATTIC FANS VS RIDGE VENT

When it comes to keeping your attic cool and well-ventilated, using both solar attic fans and ridge vents are going to give you the best results. 

First, let’s talk about solar attic fans. These fans are powered by the sun, making them energy-efficient and eco-friendly. They actively move air in your attic and exhaust it outside, preventing it from becoming a hot and stuffy space. By installing a solar attic fan, you can maintain an attic temperature within 5 to 10 degrees of the outside temperature, which helps to prevent a plethora of issues caused by extreme heat.

Now, let’s move on to ridge vents. These are passive ventilation systems installed along the ridge of your roof. They allow hot air to escape naturally, creating a flow of cool air into the attic. While ridge vents are effective, they rely on passive airflow and may take longer to achieve a complete exchange of all the air in the attic. So, here’s the exciting part: by combining solar attic fans and ridge vents, you can create a comprehensive attic ventilation system. The solar attic fan actively moves the air, while the ridge vents allow for passive airflow. This dynamic combination ensures that your attic remains cool, well-ventilated, and protected from issues caused by excessive heat.

However, if you’re going to choose between using just a solar attic fan or just ridge vents, the solar attic fan is the superior option. Its active air movement provides more frequent complete air exchanges, preventing the attic from reaching extreme temperatures. On the other hand, ridge vents alone may take longer to achieve the same level of ventilation. 

Remember, for the best results, it’s recommended to keep the solar attic fan at least 5 to 10 feet away from the ridge vent. This spacing allows for optimal performance and prevents any interference between the two systems.

If you want effective attic temperature control and ventilation, installing a solar attic fan is the way to go. But if you can use both solar attic fans and ridge vents with proper spacing, you can create the most efficient attic ventilation system possible.

HOW MUCH SOLAR ATTIC FAN COST

The price of solar attic fans can vary depending on various factors, such as the brand, size, and features. On average, you can expect to pay anywhere between $200 to $500 for a solar attic fan unit, without installation being factored in.

Installing a solar attic fan typically requires professional assistance, especially if you’re considering the roof mount option or have a complex roof structure. The cost of installation can vary depending on your location, the complexity of the installation, and any additional materials needed.

On average, you can expect to pay between $300 to $800 for professional installation of a solar attic fan. This cost may include the labor, wiring, and any necessary adjustments to your roof. You should also remember that these figures are estimates and can vary based on individual circumstances and the contractor you choose.

When considering a solar attic fan, there are two options for installation: gable mount and roof mount. If you already have a gable vent in your attic, then a gable mount installation is a more DIY-friendly option. This installation is relatively straightforward and can be done by following the manufacturer’s instructions. However, if you opt for the roof mount option, it is highly recommended to get it professionally done, especially if you have a cement or clay tile roof. These installations are more complex and require specialized knowledge and tools.

WHAT IS AN ATTIC FAN AND WHAT THEY CAN DO FOR YOUR HOME

An attic fan replaces the air inside of your attic with the air outside using the existing attic vents. They are usually installed on a gable vent or into the roof of the home.

With energy costs higher than ever, many homeowners are looking for ways to reduce their bills while still keeping the whole house cool. Choosing a more energy-efficient air conditioner is one solution but for many homes, an even better solution is an attic exhaust fan.

USING ATTIC FANS IN
COLD CLIMATES

Attic fans are very popular in cold climates because they can help to prevent ice damming in attics during the coldest months of the year. Your attic can build up a lot of moisture during the winter due to the warm temperature in the home and the cool temperature outside. This can cause serious problems to appliances in the attic or even the structure of the home. By ventilating the attic, it can help mitigate that humidity build-up. With a smart attic fan, customers simply go into their smartphone app and change the climate setting to Winter; no climbing up into the attic needed!

WHY ATTIC FANS ARE REALLY WORTH IT

Attic ventilation is crucial to homeowners because attics can be like an oven on top of your home, heating up your living space from above. When summer comes around, a typical attic can reach temperatures of over 160 degrees! In a two-story home, this heat can make the top floor unbearable! Installing an attic fan helps to lower those temperatures in the attic, helping the home stay cooler.

All homeowners dread running their air conditioner. Families often fight over the thermostat, weighing the pros & cons before reluctantly turning their A/C system on, knowing their electric bill is steadily rising.

An attic fan’s ability to cool down the attic means a cooler home and an A/C unit that gets far less work than it usually does. This could save money on upsetting repairs further down the road.

Other A/C related issues include homeowners being frustrated by the apparent delay period for their A/C system. For the first few minutes, homeowners can hear their A/C system running but the home does not feel any cooler. The reason for this is the duct work for the air conditioner is surrounded by extreme attic temperatures. These temperatures heat up the duct work so when the system is first turned on, it begins at a deficit. The duct work must first cool down before homeowners feel any noticeable difference in the living space. This is where the attic fan comes in! As we said before, attic fans greatly reduce the temperature in the attic which means your duct work will also stay cooler! This translates to your HVAC system reaching the set temperature much quicker, allowing it to run more efficiently, creating a more comfortable living environment, all while extending the life of your most expensive home appliance!

MODERN LOW PROFILE DESIGN

Our attractive roof mount Smart & Solar attic fans come in modern low profiles which are ideal for locations with heavy snow loads or heavy tropical storms. This design is second to none and has a metal housing that was built to last. This sleek design is for most pitched roof applications. Our solar attic fans have an adjustable 180 degree horizontal rotation and a 60 degree tilt to make sure you capture the sun rays perfectly.

We also offer a secondary curb flashing for any roofs that are flat or semi-flat. The curb flashing can also be installed on metal roofs for an easy installation. We pride ourselves on the highest quality of protection in the industry.

QuietCool’s Solar Attic Fan motor housings and covers are powdered coated and made out of heavy duty steel to last forever. Most solar attic fan manufacturers build their housings and covers out of plastic and are not built to last. Our attic fans also feature high-performance fan blades that cut through the air in the most efficient and effective way possible. Our Solar Roof Mount fans include an aerodynamic funnel that distributes large quantities of air evenly throughout the roof mount housing resulting in higher airflow and efficiency. Every roof mount fan, solar and smart, comes with a bug screen that keeps bugs, insects, animals, and unwanted debris from getting into the attic.

INCREASE ATTIC VENTILATION

So you got a whole house fan but need to add more venting. Sometimes that’s easy! Just add a gable and a few O’Hagins. But other times, it can be much more difficult. One area that can address the lack of venting is called “power venting.”

Power venting is the process in which a whole house fan is powered on and the attic fan is powered on as well to help move the air out faster.

We recommend using an attic fan to boost the ventilation when you are 1 to 2 square feet shy of the venting requirement.

 

Attic Fans

THE DIFFERENCE BETWEEN ATTIC FANS AND WHOLE HOUSE FANS

Attic fans are often confused for whole house fans. Back in the 1960s when whole house fans were invented, they were very popular in the South and were, incorrectly, called “attic fans” since they were installed in the attic. This confusion remains very prevalent today.

A whole house fan is used for cooling both the home and attic. You typically run a whole house fan during the evening through into the early morning – basically any time it is cooler outside. This cools, ventilates, and exhausts all the hot, stale air in your home and attic. You would never run your whole house fan during the middle of the day when it is the warmest. This is where an attic fan comes in.

Attic fans ventilate and exhaust your attic only. You use them primarily during the day but they work well in the evening and night as well. They pull air from the outside through existing vents in your attic. This allows your attic to stay within 10ºF of the outside temperature at all times when the fan is running. Without an attic fan, your attic can get up to 150ºF during the summer, which can ruin the integrity of your home and cause high electric bills.

The best system combines an attic fan and a whole house fan to cool, ventilate, and exhaust the entire home, day and night, and year-round.

ATTIC FANS VS A/C COSTS

Depending on what kind of the attic fan you are installing, you can expect to pay between $350 to $1,000 installed. The pricing varies based on the type of attic fan, the sizing requirements, and the motor type.

Depending on the size of your home, a brand new central air system installed can cost up to $20,000

Many homeowners are choosing to install an attic fan if their A/C breaks and are in need of A/C repair.

The climate in which you live is the main factor in how much you will save on your cooling costs. An attic fan only costs around a few pennies an hour to run vs A/C electricity costs.

QuietCool offers a selection of accessories to enhance the performance of your QuietCool products. Timers are available to turn off your whole house fan after set times. PollenTec screens help filter incoming air at the windows you use with your whole house fan. Adapters are available to accommodate special mounting needs for our whole house fans and more!

ATTIC FAN FAQS

Have you every noticed your A/C cycling on and off during the summer? That is because your house is heating up almost instantly after the A/C turns off because of all the heat that is built up in your attic. By running an attic fan, your attic temperature will be up to 50 degrees cooler meaning your A/C won’t have to work as hard to keep the home cool.

 

Both work well, but they serve different purposes. Attic fans simply cool and ventilate the attic while a whole house fan cools and ventilates the entire homes, including the attic. A whole house fan should only be used during the cooler times of the day while an attic fan can be used 24/7.

 

The amount of electricity used will depend on the type of attic fan that you install.

Traditional attic fans typically use less efficient motors and move less air meaning they are less efficient.

Smart attic fans typically use much more efficient motors and move more air meaning they are more efficient.

Solar attic fans are the most efficient as they will use no electricity when there is sunlight available.

Electric powered attic fans use between 20 and 400 watts, depending on the speed the fan is running on and the model chosen. Compare this to an A/C system that can use upwards of 3000 watts.

 

Yes, there will be no negative effects when running them both at the same time. You can run the attic fan with or without the A/C running.

Depending on the type of vents you have in your attic, you can choose to install a gable mounted attic fan or a roof mounted attic fan.

SMART ATTIC FAN FAQS

The only time you need to connect to a smart attic fan is to see the current conditions of the attic or to make parameter adjustments. 

For typical Bluetooth products, only one device can connect at a time, however, you can have as many devices as you want paired to the Bluetooth product.
