The answer to 'lifespan of ceiling fan' is that a well-maintained ceiling fan can typically last 10-20 years with proper care and usage. Ceiling fans are designed to operate continuously for long periods, but their lifespan can vary depending on factors like the quality of the fan, how often it's used, and the environment it's installed in.
High-quality ceiling fans from reputable brands tend to have a longer lifespan than cheaper models. Fans that are used frequently in hot, humid environments may also wear out faster than those in milder climates. Proper maintenance, such as regularly cleaning the blades and lubricating the motor, can help extend the life of a ceiling fan.
