Radon mitigation fans are designed to operate continuously for several years, but over time they may become less effective due to wear and tear, clogging or other issues. The following are some signs that it may be time to replace the radon fan:
Increased radon levels: If you have a radon mitigation system installed, and you notice that radon levels have increased, it could be a sign that the fan is not functioning correctly. Radon levels should be monitored regularly, and any increase in levels should be investigated.
Unusual noise: If you hear unusual noises coming from the fan, it could be a sign that the fan is starting to wear out. Vibrations, grinding or squealing noises are all indications that the fan needs to be replaced.
High energy bills: If you notice a significant increase in your energy bills, it could be a sign that the fan is not functioning efficiently. The fan may be working harder than necessary to draw radon out of the house, which can lead to higher energy costs.
Age: Radon mitigation fans typically last between 5-10 years. If your fan is approaching or exceeding this lifespan, it may be time to consider replacing it.
If you suspect that your radon fan needs to be replaced, it's important to contact a qualified radon mitigation professional.
