Do radon mitigation fans run constantly?
Radon system fans are constantly running to ensure that your home stays safe. Due to its constant work, fans may need to be replaced after five years or more, but it is a simple process for an experienced radon contractor.
Why is my radon mitigation system so loud?
If your radon fan is making a loud humming or whirring noise, there’s a chance that it needs replaced. Most fans last 5-10 years, with some making it up to 20. However, it’s not uncommon for them to get very loud before they finally quit.
Will a fan get rid of radon?
In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the home.
How do you know if your radon fan is working?
You can use the u-tube manometer to determine if your system is working. Look at the liquid in the tube. If it is equal on both sides, it is an indication that there is no pressure in the pipe. This means no suction from the fan (far left image) and the radon mitigation system is not working.
How long should a radon fan last?
Fans may last for five years or more (manufacturer warranties tend not to exceed five years) and may then need to be repaired or replaced. Replacing a fan will cost around $200 – $350 including parts and labor. It is a good idea to retest your home at least every two years to be sure radon levels remain low.

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.
How do you dampen the vibration from a radon fan?
Two ways to reduce vibration transfer back to the building is the install a total of four anti-vibration reducing rubber couplings instead of only two. Also, wrap each fastener that supports the exhaust with rubber to reduce the amount of vibration transfer back to the building.
Does running furnace fan reduce radon?
In many homes, blowing air in through an existing central furnace is quite practical. The use of an exhaust fan to pull air out of the house may decease the interior air pressure and draw more radon inside.
What are the symptoms of radon poisoning?
How do you clean a radon fan?
Carefully inspect the blades and scrap them clean with a screwdriver blade or other tool. Shake the fan and run it to clear out any debris in the fan. Be careful not to suck more debris in, especially fingers. If you bench test a dozen identical radon fans as I have, you will find they vary in the amount of vibration.
