Frankfort, KY: what's different here
Frankfort is the seat of Franklin County, and Kentucky's state radon office is located there, so oversight resources are close to home. The city sits about 29 miles from Lexington, roughly a 34-minute drive via the main highway. Kentucky rock types like black shale and phosphatic limestone are common uranium-bearing, high-radon-potential formations, and many Kentucky counties show elevated radon levels in state testing.
Why is my radon fan making noise?
Radon fans run continuously, so they wear over time. EPA says fans may last five years or more before needing repair or replacement. Grinding, rattling, or louder-than-normal hum can mean the fan is failing and needs service or replacement.
How much does radon fan replacement cost in Frankfort?
EPA puts fan replacement at around $200 to $350 including parts and labor. If the noise points to a bigger problem, a full new mitigation system typically averages $1,200 to $3,000, and EPA's general fix range is $500 to $2,500 depending on the house.
Can I turn off a noisy radon fan?
No. EPA says radon fans should run continuously and should never be turned off for the system to work correctly. Shutting the fan off lets radon build back up, so fix the noise instead of silencing the system.
Who fixes a radon fan noise problem in Frankfort?
Kentucky requires contractors performing radon-related services to be licensed by the state, and certified pros hold NRPP Radon Mitigation Specialist credentials. Lexington Radon Pros refers Frankfort homeowners to a Kentucky-certified (NRPP/NRSB) radon mitigation contractor at no charge.
What to do next
- Confirm the noise is the fan, not the piping, before paying for a replacement.
- Ask for a quote that separates fan replacement ($200-$350 per EPA) from full system work.
- Verify the contractor's Kentucky license and NRPP certification through the state radon office at radon.ky.gov or 502-782-2782.
- After any repair, run a follow-up radon test no sooner than 24 hours after the fan is back on, within 30 days.
- Call (859) 249-8571 or email [email protected] for a free quote from a Kentucky-certified (NRPP/NRSB) radon mitigation contractor.
