The answer to 'when to replace ceiling fan' is that you should typically replace your ceiling fan every 10-15 years, or sooner if it's showing signs of wear and tear. Ceiling fans are a common household fixture, but they do have a limited lifespan and will eventually need to be replaced for safety and performance reasons.
Over time, the motor and other components can wear out, leading to issues like excessive wobbling, grinding noises, or even the fan stopping completely. Additionally, older ceiling fans may not be as energy-efficient as newer models, so replacing an older fan can also help you save on your energy bills.
