Radon Fan Installation & Replacement

New radon fan, an upgrade, or a worn-out fan replaced, any brand, fast turnaround across Central Illinois.

The radon fan is the heart of your mitigation system, and like any motor running 24/7, it eventually wears out. If yours is loud, rattling, weak, or completely silent, your home may no longer be protected. We install and replace radon fans of every brand, even on systems we didn’t put in.

Signs Your Radon Fan Needs Replacing

  • New humming, rattling, or grinding noises
  • The fan is silent or the U-tube manometer shows no pressure difference
  • Your radon level has crept back up on a recent test
  • The fan is more than ~5–10 years old (typical lifespan)

A radon fan that stops moving air means radon can build back up to dangerous levels, often without any warning. That’s why most systems include a manometer (the U-shaped gauge); if the liquid levels are even, the fan likely isn’t working.

We Service Every Brand

We stock and install quality, quiet radon fans sized correctly for your system, whether you need a higher-suction fan for a tight slab or a quieter model for a finished basement. Because we work on all makes and models, we can replace your existing fan with the right unit and verify the system is pulling properly before we leave.

New Radon Fan Installation

Adding active mitigation to a passive system, or upgrading an older setup? We’ll evaluate your existing piping and install a correctly sized fan and warning device so your home stays below the EPA action level. Pair it with a quick system inspection and you’re set for years.

FAQ

Frequently Asked Questions

My fan stopped working / my system is loud. Can you help?
Yes. We install, replace, and repair radon fans of every brand, even systems we didn’t install. A humming, rattling, or silent fan usually means it’s time for a replacement. See our radon fan service
How long does installation take?
Most systems are installed in about half a day, and you can stay home while we work. It can take a little longer for larger homes, bigger crawlspaces, or older homes that need multiple suction points or more complicated work, but most are still done within one day.
Will the system really lower my radon?
Yes, and we guarantee it. A properly designed sub-slab depressurization system routinely brings homes from double-digit radon levels down below the EPA action level of 4.0 pCi/L. We recommend a follow-up test to confirm the result in writing, and if it isn’t below 4.0, we’ll come back and make it right.
How much does a radon mitigation system cost?
Most residential radon mitigation systems run $1,450–$2,500, depending on your foundation, the layout of your home, and where the system routes. We give a free, no-obligation estimate up front, no surprises. See what affects the price
Are you licensed and insured?
Absolutely. We’re a Licensed Radon Mitigation Specialist through the Illinois Emergency Management Agency (IEMA), license #RNM2020203, and fully insured. Radon mitigation in Illinois must be performed by a licensed professional.
