When Your Radon Mitigation Fan Needs Replacing

That low hum from your basement might be a sign your radon mitigation fan is struggling after years of continuous operation. When these fans start making grinding noises or running hotter than usual, they're often telling you it's time for a replacement before radon levels creep up. Most systems handle about five to ten years before the motor wears out, and ignoring those signs means your home's air quality could suffer. A new fan typically costs less than worrying about elevated radon readings.
