The average life span of a thermoelectric fan operating seasonally is two to three years. However, the life span of a wood stove fan depends on its quality, usage, and maintenance. Regular cleaning of the blades and ensuring the fan operates within its recommended temperature range can help prolong its life span.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

Blower fans are better for preventing mold growth than dehumidifiers because they target the damaged areas and increase the rate of evaporation, which dries out the building materials. Ideally, you should run blower fans and a dehumidifier, as this will allow the fans to move dry air over your damaged building materials, drying out the space even more quickly.
