Common Signs You Need A New Bathroom Exhaust Fan

May 2, 2023

A new bathroom exhaust fan is essential in any bathroom to maintain air quality and prevent bacteria, mould, and moisture build-up in your bathroom. Over time, these fans may become less effective or malfunction altogether. This will lead to foul odours, mould growth, and even damage to the walls or structure of your home.


Here are common signs you need a new bathroom exhaust fan

  1. Excessive noise
  2. Poor performance
  3. Foul odours
  4. Visible damage
  5. Age of the fan


Excessive noise

Bathroom exhaust fans are designed to run quietly when in use. If you notice your fan is making excessive noise, such as rattling or humming, it may be a sign the motor is failing or that there is a loose part. Any loud noises indicate the motor is dying and a replacement is needed. 


Poor performance 

The primary function of a bathroom fan is to remove moisture from the air, which prevents mould and bacteria growth. If your fan starts up more slowly than usual or the blades aren’t spinning as fast as they once did, that could mean the motor is failing or the ductwork is clogged. 


Foul odours

One of the main benefits of having a bathroom exhaust fan is that it keeps your bathroom odour-free. If you notice any unpleasant smells in your bathroom, it could be a sign that the fan is not working correctly. This could be due to a clogged or damaged exhaust duct in the fan which can lead to the accumulation of moisture and mould growth. In some instances, the bad odours could be coming from the fan itself because of mould growth inside the fan.  


Visible damage

If you notice any visible damage to your bathroom fan, such as rust, corrosion, cracks, or missing parts, it is time to consider getting the fan replaced. Over time, your bathroom fan consistently gets exposed to moisture which can cause the fan’s components and parts to degrade and break down. 


Age of the fan

Typically, bathroom exhaust fans have a lifespan of 10 years with proper maintenance and care. It’s important to keep your bathroom fan clean to prevent build-up and to ensure it runs properly. If your bathroom fan is older than ten years, it may be time to get a new fan installed.

Bathroom exhaust fans are a crucial component of your home’s ventilation system. They help to eliminate odours, moisture, humidity, mould, bacteria, and other pollutants. They also remove water vapour that can accumulate and damage walls.


If you notice any of the above signs, it is time to replace your bathroom fan.
