Most people describe the sound of an unbalanced ceiling fan as a buzzing or grinding noise. This is caused by the parts of the fan rubbing or rattling against each other as the blades spin. However, a wobbling fan can also make squeaking, rattling, or thumping sounds, depending on the severity of the balance issue.

Your bathroom exhaust fan shouldn't be loud. However, bath fans come in a wide variety of models, price points, and loudness characteristics, and yours may be louder or quieter than others you notice. Economy models tend to be the noisiest, with levels of 4.0 sones or more, which is about the sound of an electric shaver, while some high-end models can be barely audible. 

Most ceiling fans have a lifespan of anywhere from five to 15 years or 10 years on average. Just how long your ceiling fan lasts depends on the quality of the parts, how much it’s used, and how well you maintain it. A fan with a weak motor that runs on the medium setting nonstop is likely to have a shorter lifespan compared to a fan with a powerful motor that runs on the slowest setting for air circulation.

Exhaust fans push air out of spaces, removing moisture, heat, odors, and pollutants. They vent air outside through ducts, preventing mold and improving air quality. Unlike ventilation fans, which circulate fresh air in and out, exhaust fans focus solely on expelling unwanted indoor air.
