Why is my bathroom fan so noisy?

Your fan’s motor may be dirty if it’s been quiet and started making a lot of noise recently. Use a can of compressed air to clean out the fan if it’s clogged with dust, dirt, and other debris. After that, use a hand vacuum to remove any remaining debris. That’s not too difficult.
