Radon fan replacement and system repair
Fan too loud, gone quiet, or not running? Replacing a radon fan costs $575. That covers the visit, the labor, and a new fan with a five-year warranty.
Send your town and a clear photo of the fan and the gauge to (815) 370-9682.
If your fan gets louder, rattles, grinds, hums, or shakes the wall, it may be wearing out, or something else in the system may need a look. Call first. Bill can often tell over the phone whether it's the fan, the gauge, the power, or something he needs to see in person.
We check the whole system, not just the fan
The fan is the first thing people suspect, but other things can change how a system sounds and works. We check all of it before we tell you what to do next.
- Power to the fan, or a tripped circuit
- The gauge
- Loose or leaking pipe joints
- Shaking that carries into the house
- Whether the fan is the right size
- The sump lid
- The crawl space plastic
- Anything blocking the pipe
- Other wear on the system
What does the five-year fan warranty cover?
If a fan we install fails during the first five years, we replace it at no cost to you. The service visit, labor, and replacement fan are all included.
A replacement fan installed under warranty receives its own five-year term. Warranty details, including transferability, are provided in the customer packet after installation.
Outside the warranty, or on a system we didn't put in, it's a regular paid visit at the $575 price. There's no trip charge. Credit card payments carry a 3% processing fee, shown before you pay. If your system needs a larger or special fan, Bill tells you before the visit.
What should I check before I call?
- Look at the gauge and see if the liquid is uneven or level.
- Listen for rattling, grinding, buzzing, or shaking at the fan or pipe.
- Take a photo of the fan, its label, and the gauge if you can reach them safely.
- Notice whether the fan sounds different than it used to, or has gone quiet.
- If a newer home has a radon pipe with no fan, ask whether adding a fan to that pipe makes more sense than a whole new system.
Have a radon pipe with no fan on it? Read about passive radon system activation. If a remodel needs the pipe or fan moved, read about radon system relocation and rerouting.
Not sure what part you are looking at?
If you bought a home that came with a system, the fan, the gauge, the sump lid, the crawl space plastic, and the outside pipe can be confusing. Our existing radon system guide explains each part and which photos help.

Radon fan replacement questions
My radon fan is noisy. What does that mean?
The signs to watch for, the price, and what the warranty covers are near the top of this page.
My radon fan is silent. Is it broken?
A properly working radon fan is not perfectly silent. Most produce a soft, steady sound of air moving through the pipe. If the system becomes completely silent, check the U-tube manometer. A working U-tube manometer normally shows the two liquid columns at different heights. If the columns are level with each other, the system is not showing suction. The manometer shows suction, not the radon level in the home. Call Bill’s cell or send him a photo of the gauge. Service is usually within a day or two.
How do I read the U-tube manometer?
The manometer is the small clear U-shaped gauge on the pipe. It shows suction, not the radon level in the home. Uneven liquid levels usually indicate suction. If both sides are level with each other, the system is not showing suction. If the reading changes substantially from its usual mark or the fan sounds different, send Bill a clear photo of the fan and manometer at (815) 370-9682 (his cell).
Can you replace a fan another company installed?
Yes. We service common mitigation fan brands and systems we did not originally install. No trip charge. Bill looks at the whole system so you are not forced into a full rebuild if a fan swap is enough.
How fast can you replace a radon fan?
Fan replacement is usually within a day or two. Call or text Bill’s cell with a photo of the fan and manometer if you can. That number is (815) 370-9682.
Is (815) 370-9682 Bill’s cell phone?
Yes. That is Bill’s cell. Call, text, or send a photo of your fan or manometer. It is not a call center.
Can you service my radon fan brand?
Almost always. We work on RadonAway, Fantech, Festa, and other common radon fan brands, including systems another company installed. If you are not sure what you have, text Bill a photo of the fan label and the U-tube manometer.
How long does a radon fan last?
EPA says radon fans may last five years or more, and notes that manufacturer warranties tend not to exceed five years. EPA does not give a fixed replacement date. The fan tells you when it is wearing out: it gets noticeably louder, rattles, grinds, hums, or goes silent, and the manometer drops to level. If a fan we installed fails during its first five years, the service visit, labor, and replacement fan are included.

“I bought a house that had a Radon system installed in it by Bill from a previous owner. I was having an issue with the sump pump that was attached to the system and called Bill to confirm what I needed to be aware of with the radon system. Bill…”
“Bill and his crew at American Radon Systems did a great job installing a radon fan in my attic. They were in and out in short order and were careful to leave my home in the same condition they found it. Everything is working great and I am completely satisfied…”
Already have a radon system?
You do not have to know who installed it or exactly what is wrong before calling. American Radon Systems checks, repairs, activates, reroutes, relocates, and improves existing systems throughout the communities we serve.
