What is a crucial aspect of maintaining a good radon mitigation system?

Maintaining a good radon mitigation system requires continuous vigilance to ensure its effectiveness in reducing radon levels in a home. A crucial aspect of this is checking system performance and retesting for radon every two years. This process helps to verify that the mitigation system is functioning properly and that radon levels remain at or below acceptable thresholds.

Regular performance checks can identify any potential issues with the system, such as fan malfunctions, blockages, or other structural problems that could compromise the radon reduction efforts. Retesting for radon confirms that the mitigated levels do not spike above safe limits, which is essential for the health and safety of the occupants.

In contrast, other actions like painting fan components or replacing systems every five years, while potentially beneficial in specific contexts, do not directly address the ongoing assessment of radon levels and system functionality. Monthly monitoring is more frequent than typically recommended and may not be necessary for most homes, as every two years is a standard interval that balances thoroughness and practicality.
