efficiently as possible. Your attic fan can be installed one of two ways, either gable mounted or roof mounted, and is controlled by an automatic thermostat that shuts it off or turns it on.

An attic fan will perform as effectively as it should in a properly sealed and insulated attic, so that no heat or moist air can sneak its way in. This helps with your HVAC efficiency, and also protects your roof and your attic’s structure.

Your attic fan serves as a way to efficiently ventilate the space, but it is so much more than that, too. As we stated above, the temperature in your attic can be far above the outdoor temperatures. This is if you do not have an attic fan installed. Regular vents do allow for some cooling, but not to an extent that you’ll notice the difference.

A properly installed and serviced attic fan can help drop your attic temperatures by as much as 50 degrees, making your entire house cooler. This means you’ll be able to turn up your air conditioner’s thermostat by as much as 10 degrees, but still remain comfortable.

In the wintertime, moisture can quickly turn to ice or frost, and as that expands in can damage your roof and the structural integrity of your attic. An attic fan, however, can fend off the moisture before it is able to damage your roof in this manner.

Ice is not the only danger that moisture brings, either. When moisture cannot be ventilated and is left to sit, mold can start growing. Unfortunately it’s very easy for moisture to reach your attic—even your showering and cooking allows this to happen. But an attic fan can resolve this problem.

Your air conditioner will not have to work so hard to do its job when it is assisted by an attic fan. Also, it’s likely to last a lot longer—given that you schedule regular maintenance—when you don’t have to run it as often. Repairs will happen from time to time, but an efficiently working AC system is a lot less likely to give you problems than one that doesn’t have the assistance of an attic fan.
