Radon System Repair, Fan Replacement & Maintenance

A radon mitigation system needs to keep doing its job after installation. If the fan stops, the warning device changes, piping is damaged, or the system no longer performs as expected, an inspection can identify what needs attention.

Signs Your System Needs Attention

• The mitigation fan is silent when it normally runs.
• The warning device or manometer indicates a change in system performance.
• You hear unusual fan noise or vibration.
• Visible piping or connections are damaged.
• The system was installed years ago and has never been evaluated.
• A follow-up radon test shows the level is still elevated.

Fan Replacement

Fans are mechanical components and can eventually wear out. EPA notes that mitigation fans may last five years or more and may eventually need repair or replacement. The replacement fan must be appropriate for the system and installed in a suitable location.

System Evaluation

An evaluation can include checking the visible piping, suction point, fan, warning device, electrical connection, exhaust arrangement, and available testing history. The goal is to determine whether the system is operating as intended and whether additional testing is appropriate.

Retesting After Repair

If a system has been repaired or modified, a new radon measurement can help determine whether the building's radon level has been reduced as expected.

Request an Evaluation

Send the property location, the age of the system if known, the current radon result, and a description of the problem.
