Your radon fan should be replaced every 5 to 10 years, or sooner if you hear unusual noises or notice the fan running less efficiently. Typically, you'll replace it when your radon test results creep back up, signaling the fan is losing its pull. Always use a fan rated specifically for radon systems, and hire a certified professional for the job—they'll seal connections properly to prevent leaks and ensure the fan is sized right for your pipe system.
