Replace That Loud Radon Fan Yourself

Is your radon fan loud and annoying? Or has it quit already?

Did you know you can replace a radon fan yourself?

Let us show you how.

Start by removing your old radon fan

  1. First, let’s unplug the fan.
  2. Next, you will need a 5/16 nut driver or a flat-blade screwdriver.
  3. Then, you will loosen up the two clamp screws on the rubber couplers holding the radon fan in place.Radon System Clamps
  4. Then, we can turn the upper section of the pipe a little to break the seal more easily.Take apart radon system
  5. You can now remove the fan, as easy as that.

Selecting a Replacement Radon Fan

We created a radon fan replacement guide to help you find the best replacement fan. We recommend using the direct replacement for your existing radon fan when possible. This will decrease the need for radon system modifications. If the fan model is no longer manufactured, the manufacturer’s recommended replacement model will be listed. This is a guide, and all specifications should be verified before purchase. If you purchase from the links, we do earn a commission.

Installing Your New Radon Fan

  3. Pull the upper rubber coupler and pipe back down to secure it to the top of the radon fan.Pull pipe back down onto new fan
  4. As you pull the pipe back down, ensure that the neoprene gasket in the roof is sealed around the pipe rather than pulled down because it can cause a leak if it’s not sealed properly.Neoprene Seal CorrectNeoprene Seal Incorrect
  5. Next, you will tighten the screws on the clamps back up. Do NOT skip this step, or rainwater or condensation could leak into your attic.Tighten ScrewsTighten Screws
  6. You can also fine-tune the fan leveling as you tighten the clamps. We like to level and plumb the fan depending on the fan model. 
  7. Finally, plug the new radon fan back into the outlet. You should hear the fan running, and your radon fan replacement is complete.
