To keep dangerous radon gases from building up inside your home, the fan should be running constantly. If you are leaving for an extended period of time, like a “snowbird” you can turn off our system to conserve energy but know that it takes about 12-24 hours for the radon fan to clear out any built-up levels of radon once you return home and turn it back on.

How loud should a radon fan be?
The best standard would that the air velocity should not be greater than 700 FPM (feet per minute). Excessive noise and back pressure is created when too much air is moved through the pipe. According to the best standard, a 3” pipe should move no more than 34 CFM before the system is too noisy and loses efficiency.
Does radon fan make noise?
Radon Fans Wear Out Over Time: Don't wait to replace it But sometimes you might hear it making noise. The fan's bearings that help to lubricate the motion and reduce the noise start to go bad. This is mainly due to standard wear and tear that happens because the radon mitigation fan runs all the time.
How do you reduce the sound of a radon fan?
Open face fiberglass insulation can be placed on top of the membrane or in the joist cavities above the suction location to dampen the noise. The smaller the pipe size drawing air from under the membrane the quieter the air flow noise.
Should radon fan run constantly?
Frequently Asked Questions About Radon Fans and Radon Mitigation Systems. Does a Radon Fan Run Continuously? Radon fans run continuously and should stay on. It's important to remember radon fans create a negative pressure underneath the sub slab of your home.

How much does a 20 watt radon fan save?
A 20 watt radon fan can save $500 in electrical cost over ten years and is considerably quieter. Visit the Radon Fan Performancepage and look up your radon fan wattage. Then check out the fans below. In general the lower the fan wattage the quieter the fan.
How does a muffler help with radon?
EXHAUST MUFFLERS: Companies that supply radon products manufacturer different style air flow mufflers. Some of the mufflers restrict the airflow at higher airflow speeds. This would only affect high airflow systems. Their effectiveness for noise reduction also varies. In general a muffler will not reduce the airflow noise coming from the piping or the fan noise itself. The mufflers will however lower the exhaust noise if they are placed near the exhaust port. The actual noise reduction is moderate but the sound pitch is lowered which makes the noise less offensive. System exhaust noise is usually only bothersome if the exhaust is at the first floor roof and the exhaust pipe is visible from a location that is frequently occupied. A 2nd floor window that looks at a radon exhaust pipe on the garage roof or an exhaust out of a ranch roof that is visible from a rear deck would be good canidates for a muffler. The best muffler noise reduction is with the muffler installed on the end of the exhaust pipe with no chimney cap so that air flow is straight up. We have installed the muffler on the exhaust port on the roof for maximum noise reduction even though it looks a bit out of place.
How to reduce noise from piping?
INSULATING THE PIPE: Piping that is routed through a space that needs to minimize airflow noise can be insulated for noise reduction. Sliding the next size larger flexible insulated duct over the pipe in the area that needs to have quieter piping can be very effective. Using closed cell foam or thicker walled pipe is less effective.
How to tell if a fan is in the attic?
Place your hand on the fan. Then place you hand on any building component that the piping above or below the fan is attached to. On outside mounted fans feel the siding for vibration next to the first fan bracket above the fan and where the pipe enters the building. If the fan is in the attic feel any framing that the fan is attached to or the pipe rubs up against. If you feel any vibration of building components you can be sure it is being transferred back into the building. Feel the drywall inside the home that is closest to the fan location for vibration.
Can a fan be audible inside?
Fan systems installed outside should not be audible inside unless there is an adjacent window that the occupants occassionally open and they spend time near to. This noise would be from both airflow and the fan. A lower wattage fan would be the best solution. If the noise transfer is through an open second floor window then it is likely to be the piping airflow noise and the exhaust noise. The exhaust piping could be switched to thicker walled PVC piping or even a muffler on the exhaust stack if aesthetics is not a concern.
Can radon be piped through drywall?
ROUTING NEW CONSTRUCTION PIPING: The air moving through a radon pipe has enough noise to be carried through drywall. Try to not route new construction passive radon pipes through walls adjacent to a bedroom, especially the master bedroom. Builders rarely think about this detail. If you can hear air flow noise through the drywall your only partial solution is installing a lower wattage fan in the attic. If it is really bothersome to the owner the system may need to be re-piped up the outside of the home.
Can you wrap a radon fan?
If the radon fan is located in the attic of the house or garage you can wrap the fan with fiberglass insulation. The air flowing through the fan will maintain the fan temperature. I have never found a radon fan more than a bit warm even if the motor has been stalled by some blockage so there appears to be no concern about causing a fire from the fan overheating.
Why does my radon mitigation fan make a noise?

What to do if radon is making a noise?
If it’s making noises, it should be inspected by a professional who can diagnose and fix problems with your system. When you need to replace your radon mitigation fan it is advisable to replace it with one having at least the same flow and static pressure capability.
How long does it take for radon to return to the air?
