Replacing the fan in your radon mitigation system is a straightforward but crucial task. Over time, the fan can wear out or become noisy, reducing its effectiveness. I had to swap mine recently after noticing the radon levels creeping up. It took about an hour, mostly detaching and reattaching the vent pipes before securing the new unit. Making sure the new fan matches the old one's airflow specs is key. It's a satisfying fix that restores peace of mind.
