Determining if your radon fan needs to be replaced.


Radon fans function like a heart in a radon mitigation system. They work continuously pulling radon laden air from the ground and vent it out of the building. Radon fans are designed to run continuously and have an average service life of about 10 to 12 years.

All radon fans will eventually wear out and require replacement. Typical radon fans have an electric motor and sealed bearings that are not serviceable. As those moving parts of the fan begin to wear out, they will usually give you signs your radon fan may soon need to be replaced. Let's discuss how to know when it's time to replace your radon fan.

Excessive Noise

Most often, excessive noise is the first sign your radon fan is beginning to fail. Not in every case but almost always, excessive noise from your radon mitigation system is due worn and failing bearings and in deteriorating. If your radon fan sounds like this, it might be time for a new one.

Another sign that you need to replace your radon fan? Your old one stops working! You can tell that your radon fan is no longer operating when your system’s alarm goes off or your manometer is level at zero, as shown below.
