A blower and a fan serve different functions, so whether a blower versus a fan is better depends on what you need. If you need to heat or warm your home, it’s important that the HVAC blower is in good working condition. If you want to prevent an AC unit from overheating, make sure to keep up-to-date on condenser fan maintenance.

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.

Regularly clean fan grilles, check for dust buildup, and ensure proper venting to prevent mold growth.

Most duct booster fans are not designed to run continuously, though some models can be programmed for constant operation. Typically, they are controlled by the user via a switch, controls on the unit itself, or by being wired to the HVAC system's thermostat. Wiring the fan to a thermostat allows it to run automatically only when heating or cooling is active, which saves energy and is an effective way to activate the fan only when needed to address issues like uneven room temperatures.
