Unfortunately, it doesn’t come with a set of louvers or a vent, so you’ll have to purchase these separately. While it doesn’t include a remote control, there is a programmable thermostat. Those looking for a simple, effective approach to whole-house cooling will want to check out Cool Attic’s CX30BD2SPD two-speed belt-drive fan. This model comes in both 24- and 30-inch sizes, which are suitable for homes between 2,000 and 3,000 square feet.

His work has also appeared in Business Insider's Insider Picks, and before his writing career, he was a full-time carpenter living in New York City. There, he worked as part of a team designing, building, and installing large furniture pieces, as well as performing a variety of home repair and maintenance projects. Alex currently lives in Los Angeles, CA, and spends his free time exploring the beaches and mountains with his fiancé and their dog Louie. Its high-quality construction also makes this an especially sturdy model, and its rubber bushings help to reduce vibration and noise, keeping its operating level at about 51 decibels. Solid foam dampers flip into place and form a tight seal when the system is not in use, preventing warm air seepage and increasing its overall efficiency.

Difference between Whole House Fans and Attic Fans

For those who are sensitive to noise, some fans are better choices than others. Once we knew what to look for, we performed extensive product research to compile a list of fans we thought would meet our criteria. We then compared these fans’ power, design, and prices to ensure they offered enough value to make our lineup. Those that didn’t were cut, while those that did were given awards based on their strengths.

Typically, a whole-house fan shouldn’t be run during the day because doing so would heat your home instead of cooling it. However, it can be run for brief periods of time in certain situations if you need a complete air exchange, for example, on an unusually warm winter day. A whole house fan increases ventilation throughout the entire house, not just the attic.

While other preventative measures exist, like roof deicing cables or roof rakes to remove snow, adequate ventilation can’t be overlooked. Keeping the attic cool in the winter will minimize the snow melt that can back up or leak into the house. After choosing the ceiling joist on which to mount the fan, make a cutout (1 inch by 2 inches) on either side of the ceiling joist from the attic.

If you live in a place with mild weather, these fans can be a cheaper and more energy-efficient way to cool your home than a traditional air conditioner. This gable-mount attic fan features sturdy galvanized housing and a 3.1-amp motor that provides ventilation for up to 1,600 square feet of attic space. It also comes with a built-in thermostat that you can set to automatically activate and shut off the fan when the air gets to a certain temperature. For the value-minded shopper, this fan provides a lot of flow for the buck.

If the attic fan is located behind the home’s existing gable vent (rather than a shutter-style fan that replaces the vent), the fan will be nearly invisible from the outside. Thanks to its powerful 3,945 CFM airflow, this fan is capable of cooling two-story homes up to 3,400 square feet in size. We’re also a big fan of its impressive warranty, covering parts for three years, and the motor for 10 years. Folks shopping for a quality direct-drive fan that will offer low maintenance and very little noise might want to take a look at the QA-Deluxe. This whole-house fan has an efficient direct-drive motor with two speeds, producing up to 3,945 CFM of airflow in homes up to 3,400 square feet.

This allows quick recognition from the hallway for the automatic shutter installation. There are two types of whole-house fans, and installation instructions for the two differ. Read the instructions for belt-driven fans or direct-drive fans carefully. Installing a whole house fan is tricky and should be done by a professional. An experienced professional should take your attic measurements and install your dedicated circuit wiring and, if needed, your new attic vents. Cooling using a whole house fan can substitute for an air conditioner in some climates.

Using Whole House Fans in Humid Climates

Whenever outdoor air temperature is cooler than inside the home, windows are opened and the fan is turned on. These products are designed to run during the evening and early morning (the coolest parts of the day). The purpose of a whole-house fan is to rid your home of heat that builds up while the sun is out.

You don't need to choose between a whole-house or attic fan; they are not mutually exclusive. You can install a whole-house fan to draw air through the house and an attic fan to remove that air from the attic. The Roof Mount Whole House Fan Series is our newest and most exciting line of whole house fans. With multiple applications, you can now experience all the benefits of our revolutionary whole house fan with little to no attic space.

These appliances are installed in a central location in the home, such as in the ceiling of a second-story hall or landing, where the fan can provide increased airflow to the whole home. Because a whole-house fan exhausts stale, warm air into the attic, a properly sized attic ventilation system is also required to exhaust that air out of the attic. In colder months, attic fans can help avoid damage caused by ice dams as well. The fans cool the attic, equalizing the temperature between the attic and the outside.
