Radon System Maintenance & Support
Your safety doesn't end at installation. Use this resource to understand your system's maintenance needs, monitor its performance, and stay compliant with national safety standards.
The Two-Year Standard
The EPA recommends re-testing your home every two years to ensure your system continues to operate effectively. Over time, changes in soil composition, house settling, or fan wear can impact the system's performance.
Regular re-testing is the only way to verify that your indoor air quality remains below the action level. As NRPP-certified radon experts serving East Tennessee, we provide certified measurement services to give you continued peace of mind.
Quick Performance Check
- ✔ Check your U-Tube Manometer monthly.
- ✔ Listen for unusual fan vibration or noise.
- ✔ Ensure your audible alarm is powered.
- ✔ Schedule a professional test every 24 months.
System Ownership Resources
Reading the Manometer
The liquid levels should be uneven. If they are level at "0," your fan has lost power or failed.
Fan Warranty & Lifespan
Radon fans carry a manufacturer warranty of five to seven years, depending on make and model, and can often continue operating beyond that. We offer seamless fan replacements when the time comes.
Home Renovations
Adding a room or finishing a basement? Call us to ensure your system's suction remains balanced after the change.
Health Facts
Radon is the leading cause of lung cancer in non-smokers. Continued monitoring is your best long-term defense.
Priority Support
Existing customers receive priority scheduling for maintenance and performance audits.
System Ownership FAQ
My audible alarm is going off. What should I do?
An alarm indicates your system's suction has dropped below normal, which usually means fan failure or a blockage. Don't ignore it. Contact us to schedule a service call so we can diagnose and correct the issue.
My manometer reads flat or shows no liquid movement. Is my system broken?
Likely yes. A level reading at "0" typically means the fan has lost power or failed. Check that the fan is plugged in and the breaker hasn't tripped; if the reading stays flat, schedule a service visit.
A re-test came back elevated again. What now?
This can happen due to fan wear, structural changes, or shifts in soil conditions over time. In most cases, adjusting or replacing the fan restores proper suction. If the system needs a redesign, we'll walk you through what's changed and why.
How much does a post-mitigation or re-test cost?
A standard verification test is $225 and includes a return trip to retrieve the monitor after a 48-hour delay and 48-hour test period. See our full cost breakdown for other pricing details.
I'm selling my home. Does my existing system need anything before closing?
Buyers and their agents often request a current test result as part of the transaction. If it's been close to or past two years since your last test, scheduling a fresh one ahead of listing can prevent delays during closing.
Is Your Home Due for a Re-Test?
