best attic fan to buy
The best attic fan for you will depend on a number of factors including how large your space is, how you'd like the unit to be powered, how you'd like it mounted, and whether or not you want an included thermostat and humidistat. For spaces up to 4,800 square feet, we recommend the QuietCool Smart 2830 CFM Power Gable Mount Attic Fan as it's easy to install, simple to use, and extremely energy efficient. If budget is a concern, the iLIVING 800 CFM Shutter Exhaust Fan is our top choice. This unit comes in under $100 and can handle spaces up to 1,200 square feet.
An attic fan is a type of fan that is installed in the attic for the purpose of moving hot air outside and pulling cool air into the attic. This keeps the attic cool and dry in order to prevent moisture damage and mold infestations.
An attic fan needs to be installed through the top of the roof in the attic or through the walls of the home. Make sure that the sides of the fan are properly secured under the shingles or under flashing to prevent leaks. Don't forget that the electric power supply will need to be connected inside the attic.
Alternatively, some attic fans can be powered by solar panels, though these kits are more difficult to install. Keep in mind that while some experienced DIYers may be able to handle this installation, it's a task that is usually better left to professionals.
Install an attic fan in the attic and turn it on remotely when necessary or invest in an attic fan that automatically turns on when the temperature within the attic reaches a set point. The attic fan will pull cool air from outdoors into the attic space and push hot air outside, reducing the amount of energy necessary for the air conditioner to cool the home.
An attic fan should run for at least 15 minutes at a time to ensure that the warm, moist air inside the attic is fully exchanged for cool, dry air. However, many products can be connected to a thermostat, allowing them to turn on whenever the heat inside the attic space reaches a set temperature. This set-it-and-forget-it method is a great option to ensure that you don't forget to manually turn the fan on.
You can use an attic fan with blown-in insulation, however, you do need to make sure the fan is designed not to blow the insulation around your attic. To remedy this, you can build a box or sides around your fan to make sure the air is flowing up towards the roof and won't catch insulation into the airflow of the fan.
The solution is simple: Ensure proper attic ventilation. One of the best ways to do that is to install an attic fan. These circulate fresh air, slow mold growth and stabilize the temperature differential between the exterior and interior of the roof.
As long as the unit is in direct sunlight, it will run as needed, pumping air out of your attic space. Remington also sells an optional 110-volt adapter so the fan can run at night and on overcast days. The fan vents up to 2,000 square feet of attic space and comes with a lifetime limited warranty.
This 50-pound, gable-mount fan is recommended for around 7,500 square feet of space. That much draw would cause problems in almost any normal attic. But if you have a structure like a pole barn that needs ventilation, it may be the fan for you.
Many consider attic insulation safe and effective, but direct sun on your roof can radiate heat into the attic space which promotes moisture and mold growth. Attic fans help to push hot air out while also pulling fresh, cool air in through the vents in your soffit, gables, and ridge.
There are a couple of different fan styles homeowners can use to help control the temperature of their attic space. However, their functions differ somewhat. Depending on your layout, your home may be better suited for one of the following types of fans.
Attic venting fans serve a different function, removing the hot and moist air from the attic and leaving the space below the attic floor alone. These fans circulate the air within the attic, pulling fresh, cool air from the vents (like the ones in your soffit) and pushing hot air outside.
In colder months, attic fans can help you avoid damage caused by ice dams as well. The fans cool the attic, equalizing the temperature between the attic and outside of the home. This prevents snow from melting on your roof and freezing when it hits the cold gutter.
Your attic fan must be built from material sturdy enough to survive the excessive heat that can build up in an attic. Cheaper fans with plastic components may begin to fail over time under these conditions. In the winter, plastic often becomes very brittle, making it easy to snap the fan blades under normal use.
Whole-house and attic fans are also capable of pulling carbon monoxide back into the home through a damaged flue. Be sure that your flues are in good operating condition, and that your furnace, oven, fireplace, and other appliances that use fuel are ventilating properly.
As mentioned earlier, adjustable thermostats give you the ability to simply set a dial and forget about the fan. When the temperature within the attic reaches a set point, the fan will turn on and start venting the heated air, cooling the attic space.
The right attic fan for you primarily depends on the size of your space and the type of fan you are looking for. One of the best solar-powered attic fans available is the Broan Surface attic fan which comes with a 28-watt solar panel, built-in waterproof flanges, and enough power to ventilate a 1,200 square foot space with its 537 CFM. This pick definitely cannot compete with an air conditioning system, but is best suited for smaller attics or crawl spaces. 041b061a72
