Efficient Louisville Radon Mitigation

A non-functioning radon fan allows radon gas to accumulate inside the home, often reaching levels far above the EPA's action level of 4 pCi/L. Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths annually, making prolonged exposure a serious public health risk. The danger is particularly high in lower levels of the home, such as basements, where radon concentrates most heavily. Prompt repair of a failing system is one of the most important steps a homeowner can take to protect their family's long-term health.

Yes, radon fans are designed and built to operate 24 hours a day, 7 days a week, 365 days a year. Unlike HVAC systems that cycle on and off, radon fans must maintain constant negative pressure beneath the foundation to prevent radon from entering the home. Turning the fan off, even temporarily, allows radon to begin accumulating almost immediately, depending on local soil conditions and radon source concentration. If you are concerned about energy costs, rest assured that most radon fans are very energy-efficient and cost only a few dollars per month to operate.

Several warning signs indicate your radon system may need repair, including rising radon test results, a non-functioning fan, unusual noises coming from the fan, or visible pipe damage. Many systems include a visual warning indicator, such as a U-tube manometer, which shows whether the system is maintaining proper suction. If the fluid levels in the manometer are equal on both sides, the system is likely not functioning correctly. Any time your radon levels test above 4 pCi/L with the system running, a professional diagnostic inspection is strongly recommended.
