How Often Should I Book Radon System Maintenance?
You should schedule professional radon mitigation system maintenance every two years to ensure optimal performance. While you should check your system’s U-tube manometer regularly to verify the exhaust fan is running, only a trained technician can properly inspect the entire pipe network, electrical connections, and fan housing for weather damage or leaks.
Furthermore, the EPA strongly recommends retesting your home’s air every two years. Regular upkeep prevents unexpected failures, guaranteeing your indoor environment remains consistently healthy.

What our clients say
I have used Radon Control Products at two of my homes in Sapphire, NC. Each time Henri diagnosed the problem and installed a radon mitigation system. Within days my radon levels went from over 4 to under 1. He coordinated work with an electrician and gutter contractor to turn key the installation. I would highly recommend Radon Control Products to anyone who is in need of radon related services.

Common Questions
About Radon Repair & Maintenance
Everything you need to know about radon system repair & maintenance in Western North Carolina.
How long do radon mitigation fans typically last before needing replacement?
Most radon mitigation fans are built to run continuously and typically last between five and ten years, though many perform well beyond that range with proper radon system maintenance. Fan lifespan depends on several factors, including the quality of the unit installed, how hard it has to work to maintain suction, and the environmental conditions it operates in. Fans installed in damp or unconditioned spaces like crawl spaces may experience more wear over time.
Rather than waiting for a fan to fail completely, proactive radon system maintenance is the smarter approach. Periodic inspections can catch early signs of motor fatigue, reduced airflow, or unusual noise before they lead to system failure. Pairing regular inspections with routine radon testing ensures your system is still delivering the protection your family depends on, not just running in the background unverified.
Can a radon fan be repaired, or does it always have to be replaced?
In most cases, radon system repair for a failing fan means full replacement rather than component-level repair. Radon mitigation fans are sealed units, and the internal motor is not designed to be serviced or rebuilt in the field. Attempting to repair a failing fan rather than replace it typically results in a short-term fix that leads to repeat failures and continued elevated radon levels in your home.
The good news is that fan replacement is a straightforward radon system repair when handled by a certified professional. The right replacement fan must match the suction and airflow requirements of your specific system, which is why professional assessment matters. After any fan replacement, follow-up radon testing should always be performed to confirm the system has returned to effective operation and your indoor radon levels are back within an acceptable range.
Why did my radon levels go up even though the fan is still running?
A fan that is running is not necessarily a fan that is working effectively. Radon levels can rise even with an operational fan for several reasons, and diagnosing the root cause is exactly the kind of complex radon system repair work we handle regularly. Common culprits include a fan that has lost suction power over time, a new crack or opening in the foundation that has created a pathway the system cannot address, or a pipe connection that has come loose and is compromising airflow.
Changes to your home, like a finished basement, added ventilation, or even shifting soil beneath the foundation, can also reduce system effectiveness. This is why radon system maintenance should include periodic radon testing rather than relying solely on visual checks. A fan that appears to be running normally can still be underperforming in ways that only a proper test will reveal.
How do I check if my radon system is still reducing radon levels?
The most reliable way to confirm your radon system is still performing effectively is through professional radon testing. Many mitigation systems include a visual indicator, typically a small U-tube manometer mounted on the pipe, that shows whether suction is present. If the fluid levels are uneven, suction is being maintained. If they are level, something has gone wrong. However, this gauge only tells you the fan is creating pressure, not that radon levels in your home are actually low.
Routine radon system maintenance should always include periodic radon testing to verify real-world results. The EPA recommends retesting every two years even for homes with active mitigation systems. At Radon Control Products, we can inspect your existing system, assess its current performance, and conduct accurate radon testing to give you a complete picture of whether your home remains protected.
Can I replace a radon fan myself or hire a professional?
Replacing a radon fan may seem straightforward, but there are important reasons to have a certified professional handle this radon system repair. The replacement fan must be correctly matched to the suction pit, pipe diameter, and airflow demands of your specific system. Installing an underpowered or oversized fan can result in a system that runs but fails to adequately reduce radon levels, leaving your family with a false sense of security.
A certified radon system maintenance professional will also inspect the full system during a fan replacement, checking for pipe integrity, connection points, and any new pathways that may be affecting performance. Most importantly, professional replacement includes follow-up radon testing to confirm the repair restored the system to effective operation. That final verification step is what separates a true fix from an assumption that everything is working as it should.
