Versailles, KY: what's different here
Versailles is the seat of Woodford County, about 17 miles and roughly 22 minutes by car from Lexington via the main highway. The county sits on irregularly bedded Bluegrass limestone that can contain uranium- or radium-bearing materials which generate radon. The EPA classifies Woodford County as radon Zone 1, meaning the predicted average indoor radon screening level is above 4 pCi/L. KGS notes a few areas of high radon concentrations in the Bluegrass region and recommends testing homes in affected areas.
What does a radon fan noise problem mean?
A radon fan runs continuously, so wear is common over time. EPA says radon fans may last five years or more, and manufacturer warranties tend not to exceed five years. A loud or rattling fan can be a sign the motor is failing and may need replacement.
Why not just switch off a noisy fan?
EPA says the fan in a radon mitigation system should never be turned off because it must run continuously for the system to work correctly. Shutting it off lets radon build back up. Get the fan repaired or replaced instead.
How much does it cost to fix a radon fan in Versailles?
EPA says replacing a radon fan typically costs about $200 to $350 including parts and labor. Adding a vent fan to an existing passive system costs about $300. A full new system averages $1,200 to $3,000 according to a national-style cost guide.
Does a radon fan raise my electric bill?
Yes, but only slightly. An active radon fan draws 100 to 300 watts continuously, which can add about $30 to $300 per year to the home's energy bill. EPA confirms mitigation systems with fans are more effective but slightly increase the electric bill.
How noisy should a working radon fan be?
A properly working system should run quietly in the background. Fan sizing matters: EPA notes a typical house may need fan capacity greater than 500 to 1000 cfm for 90% radon reduction, depending on house size and natural infiltration rate. Ask the pro whether your fan is sized and installed correctly for your home.
What to do next
- Retest your home with a radon test kit to confirm levels at or above the EPA's 4 pCi/L action level.
- Ask the pro whether the noisy fan can be repaired or needs full replacement, and request the price in writing.
- Verify the contractor's Kentucky radon license and NRPP/NRSB certification at radon.ky.gov or by calling 502-782-2782.
- After any fan work, retest at least every two years to be sure radon levels stay low.
