Radon Fan Replacement & System Repair in Fort Wayne
Radon fans run day and night for years, and eventually they quit. If your manometer reads level or the fan sounds wrong, your system may not be protecting you anymore.

If the liquid in your radon manometer is level on both sides, the fan has likely stopped. A replacement fan usually goes in within an hour or two, along with a check of the pipe and seals and a retest. We connect Fort Wayne homeowners with local pros for radon fan replacement and repairs.
How to tell your radon system stopped working
The manometer is your gauge. When the system runs, the liquid sits higher on one side. When both sides are level, there's no suction. Other clues: the fan is silent when you stand near it, it makes grinding or rattling noises, the outlet it's plugged into tripped, or a new radon test came back high.
What a repair visit includes
The technician checks power to the fan, then the fan itself. If it's failed, they swap in a new one sized for your system. They also look for cracked or disconnected pipe, failed seals at the slab, an open sump lid, or ice blocking an exterior vent pipe in winter. Once it's running, they confirm suction on the manometer and recommend a retest.
Systems that never worked well
Some older systems were undersized or poorly placed from the start. If your system runs but radon is still high, the fix may be a stronger fan, an additional suction point, better sealing, or tying in a crawl space that was missed. A pro can measure suction at different points to figure out which.
Bought a house with a radon system?
Find the manometer and check it. Look for a label with the install date and installer. If there's no paperwork, a system check and a fresh radon test give you a baseline.
Signs your radon system needs service
- Manometer level on both sides
- Fan silent, humming or rattling
- Tripped outlet or breaker
- New test above 4.0 pCi/L

Frequently asked questions
How long do radon fans last?
Many run for years before failing, but life varies with the model, moisture in the pipe and installation location. Checking the manometer a few times a year catches failures early.
Can I replace a radon fan myself?
Some handy homeowners do, but the fan must be rated for radon, sealed properly and installed where exhaust can't leak into living space. A pro also checks the rest of the system.
Why is my radon fan loud?
Worn bearings, loose mounting, or water in the pipe can cause noise. A new rattle or grinding often means the fan is close to failing.
My system runs but radon is still high. Why?
Common reasons are open entry points, an untreated crawl space, or a fan too small for the soil under your slab. A diagnostic visit can pinpoint it.
Should I retest after a fan replacement?
Yes. A short-term test after the new fan has run at least 24 hours confirms the system is working again.
