What should I do today if the fan stopped?
EPA says a working mitigation fan should run continuously, so do not leave it off while waiting for repair. Check the manometer first, since a fan that has stopped shows a change in the pressure reading. Then contact a local pro for diagnostics and ask about same-day availability.
Why does a silent fan matter?
A silent fan means the system is no longer pulling radon from under the house. Radon levels can climb right away. EPA says a failing fan should be repaired and the home tested again.
What should I check when hiring a pro?
Kentucky law says no person or business may conduct radon mitigation without proper certification. Verify the contractor is certified by the state's radon program. Ask the pro for proof of licence and insurance before work starts.
How long does a radon fan last?
EPA says radon fans may last five years or more. Manufacturer warranties tend not to exceed five years. Plan for repair or replacement after that point.
What to do next
- Check the manometer on the pipe to confirm whether the fan is running.
- Verify the contractor's Kentucky radon certification with the state radon program before hiring.
- Ask for a written quote that lists fan replacement with parts and labor.
- Schedule a retest 24 hours after the repaired fan is running, per EPA guidance.
