When Should you Replace Your Bathroom Exhaust Fan? 

Jul 8, 2021

If you ask us, the exhaust fan is the unsung hero of the bathroom. From eliminating odors to preventing mold growth, your fan does a lot to keep your bathroom in a presentable condition. While they are meant to last a good number of years, your exhaust fan will eventually need to be replaced. If you’re thinking it may be time to replace your bathroom exhaust fan or have suspicions that yours is on its way out, here are some signs to be aware of.


Your fan sounds different when turning the fan on or off

If any electromechanical device in your home starts to sound different in any capacity, it is usually worth checking out. A loud and clunky sound may mean that the blades are out of alignment or that the bearings are failing. In these situations, it’s best to have a professional come in to ensure your fan is working properly.


Your fan is constantly louder

Some fans are louder than others and it’s very normal for your fan to produce some sound. However, if you notice a change in the constant volume of your bathroom exhaust fan, this may indicate that the motor is dying. When the fan motor dies, the bathroom exhaust fan needs to be replaced.


Your bathroom is staying wetter longer

Don’t wait if you notice moisture lingering in your bathroom. With extra humidity and multiple water sources, mold is just waiting for the perfect opportunity to dominate your bathroom. Your exhaust fan may not be carrying its weight if you’re noticing the humidity in your bathroom is off. 


It’s surpassed its life expectancy

Well cleaned and maintained bathroom exhaust fans are expected to last about 10 years. Depending on your usage and upkeep, it may not last that long. If you don’t know how old your exhaust fan is, and don’t remember ever having it serviced, it may be in your bathroom’s best interest for you to have it inspected to ensure it’s working properly.


Plenty of signs can indicate that something may be wrong with your bathroom exhaust fan and it’s in need of replacement. The good news is that many of these signs are something you will naturally notice before the problem gets too severe.
