How long does a whole house attic fan last?
You can expect a whole house attic fan to last about 10 to 20 years, with an average of 16 years. Although they were a standard appliance in the hallway ceiling of Florida homes before air conditioning, we don’t see too many whole house fans anymore. And the ones we do come across are often long-ago abandoned.
That’s a shame, because the U.S. Department of Energy rates them as an excellent appliance for energy efficiency, used during the spring and fall months.

NOTE: These life expectancies are based on data provided by InterNACHI, NAHB, FannieMae, and our own professional experience. Because of the numerous variables that can affect a lifespan, they should be used as rough guidelines only, and not relied upon as a warranty or guarantee of future performance.
