How long do radon fans last?

Most radon mitigation fans run several years of continuous use before wearing out. When one fails, radon can return to pre-mitigation levels, so periodic testing matters.

How do I know if my radon system is still working?

Check the manometer gauge on the pipe – if the two fluid columns are level, there's no suction and the fan has likely failed. When in doubt, a quick test tells the truth.

Can you service a system another company installed?

Yes. We repair, replace, and re-test systems regardless of who installed them.

Radon System Repair & Existing System Testing

A radon mitigation system isn't "install it and forget it." Fans have moving parts and typically last several years before they wear out – and a failed fan means radon can climb right back up without you knowing. If you already have a system, we keep it working.

Signs your system may have failed

The manometer (the U-shaped gauge on the pipe) shows equal fluid levels – meaning no suction
The fan is silent or making new noise/vibration
It's been 5+ years since the fan was installed
You've never re-tested since the system went in

What we do

We test your current radon level, inspect the system, and repair or replace worn fans and failing components – then re-test to confirm you're protected again. If you inherited a system with a home purchase, we'll tell you honestly whether it's doing its job.

Rule of thumb: re-test every 2 years, and any time the fan is replaced. Radon doesn't take a year off.
