Radon mitigation systems play a critical role in keeping radon levels low inside Colorado Springs homes. But like any mechanical system, they require attention over time. Wear, shifting soil conditions, and aging components can all reduce performance. Knowing when to schedule radon system repair helps you stay ahead of potential problems and protect your household from elevated radon exposure.
How Long Do Radon Mitigation Systems Last Before Needing Repair?
Most radon mitigation systems installed in Colorado Springs homes are built to last. The piping and structural components can hold up for decades with minimal attention. However, the radon fan, which is the mechanical heart of the system, typically has a lifespan of around 5 to 10 years depending on the model and how continuously it operates.
Colorado Springs presents unique challenges due to our local geology. High uranium content in the soil means radon fans often run under heavy demand around the clock, which can shorten their operational life. Seasonal temperature swings also place added stress on exterior components and seals over time.
The good news is that catching early signs of wear can help prevent a full system failure. If your system is approaching the 7 to 10 year mark, it is worth scheduling a professional inspection. A timely radon system repair can restore full performance and keep your home’s radon levels well below the EPA’s recommended action level of 4.0 pCi/L.
How Do I Know If My Radon Mitigation System Is Still Working?
Even a well-installed radon mitigation system can lose effectiveness over time without regular attention. There are several clear indicators that your system may need radon system repair, and knowing what to look for can help you avoid prolonged exposure to elevated radon levels.
- The U-tube manometer shows no pressure difference. Most systems include a small gauge on the piping that displays suction levels. If the fluid levels are even or the gauge reads zero, the fan may not be creating adequate airflow.
- You cannot hear or feel the fan running. A functioning radon fan produces a low, steady hum. If you place your hand near the fan housing and feel no vibration, or hear nothing at all, the motor may have failed.
- Radon testing results come back elevated. Periodic radon testing is the most reliable way to confirm your system is doing its job. If a test shows levels at or above 4.0 pCi/L, your system likely needs professional attention.
- Visible damage to piping or connections. Cracks, separations, or exposed joints in your system’s PVC piping can compromise suction and allow radon to bypass the mitigation pathway entirely.
What Does It Mean If My Radon Fan Is Making Strange Noises?
Unusual sounds coming from your radon fan are one of the most common early warnings that radon system repair may be needed. A properly functioning fan should produce a consistent, quiet hum. When that sound shifts to rattling, grinding, or buzzing, it typically points to an internal issue that deserves prompt attention.
In many cases, the bearings inside the fan motor are beginning to wear out. This is especially common in Colorado Springs homes where fans run nonstop due to the region’s naturally high radon levels. Worn bearings create friction, which produces that unmistakable grinding noise. If left unaddressed, the fan can overheat and eventually stop working entirely.
Other causes can include loose mounting hardware, debris caught inside the fan housing, or vibration transferring to nearby surfaces. While some of these fixes are relatively straightforward, a certified technician can properly diagnose the root cause and determine whether the fan needs a targeted repair or a full replacement to keep your radon mitigation system running at peak performance.
Why Are My Radon Levels High Even With a Mitigation System Installed?
Discovering elevated radon levels when you already have a mitigation system in place can be frustrating. However, there are several reasons this can happen, and most of them point to issues that a professional radon system repair can resolve.
- The fan has lost suction power. Over time, fan motors weaken or fail entirely. Without adequate suction, the system cannot pull radon from beneath your foundation effectively.
- New cracks have developed in the foundation. Colorado Springs homes are subject to soil shifting and settling. New cracks in your slab or basement walls can create additional entry points for radon gas that your current system was not designed to address.
- Seals around piping or access points have deteriorated. Caulking and sealant materials break down over the years, allowing radon to seep past the mitigation pathway and into your living space.
- The system design no longer matches your home’s conditions. Changes like finishing a basement, adding an addition, or altering airflow patterns can shift how radon moves through your home, reducing the effectiveness of the original setup.
- Environmental radon levels have increased. Soil conditions in Colorado can change over time, and naturally occurring uranium deposits may produce higher concentrations of radon that exceed your system’s current capacity.
How Often Should a Radon System Be Inspected or Tested?
Routine inspections and radon testing are the most dependable ways to confirm your system is still protecting your home. Many Colorado Springs homeowners assume their system is working simply because it was installed, but ongoing verification is the key to long-term effectiveness.
- Test radon levels every two years at minimum. The EPA recommends retesting your home regularly to catch any changes in radon concentration. This is especially important in Colorado Springs, where over 50% of homes exceed the 4.0 pCi/L action level.
- Visually inspect your system each month. A quick check of the U-tube manometer and a listen for the fan can help you catch problems early before a full radon system repair becomes necessary.
- Schedule a professional inspection every two to three years. A certified technician can evaluate components that are not visible to the average homeowner, including internal fan conditions, sealed joints, and sub-slab pressure levels.
- Retest after any major home renovation. Changes to your foundation, HVAC system, or overall home layout can affect how radon enters and circulates through your home, making a follow-up test a smart step.
