How many fans can I install?
Usually 2-3 fans are sufficient to provide good cooling. Once you have decided on the size of the fans, you need to choose the correct size. The point is that the size of a cooler affects its performance and the level of noise it produces. The larger the cooler, the more air it can pass through itself per unit of time and the quieter it works.

Why is radon fan so loud?
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.
Is a bigger radon fan better?
Experience in choosing the best radon mitigation fan is important. Bigger is not better yet too small will result in compromised effectiveness in cold weather. Oversized fans can cause noise, excess energy loss and problems with other building systems such as combustion appliances.

How to mitigate radon in a house?
The easiest time to install this is when the house is under construction, and the sub-slab gravel pad can be easily accessed to lay down a radon collection mat or pipe along the interior perimeter of the home. When this mat or pipe is attached to a vertical vent pipe which extends out through the roof, a negative pressure is created in the pipe, either actively via an in-line fan or passively due to the stack effect. This negative pressure draws soil gases up and out of the house.

or, the home is tested for radon after construction and shows an indoor radon concentration level of ≥ 4 picocuries/liter, regardless of what radon zone the home is located in ( EPA Indoor airPLUS ).

Why is it recommended to install radon fans in attics, garages, and outside?
As you know garages, attics, and outside the house are not conditioned spaces of a house. These places have plenty of air circulation. So in the rare event of your radon system leaking, the excess radon gas will be vented outside. Moreover, this will prevent the gas from getting ino the conditioned living areas of the house where it will be circulated thorughout the house causing dangerous health risks.

Why does my radon fan make a gurgling noise?from syracuseradonmitigation.com
This is almost always due to high water table following a recent heavy prolonged rainfall or snow melting. If the water level in the ground rises up to the the bottom of the basement floor, to where it comes close to or in contact with the concrete the suction from the fan begins to lap the water up into the pipe, which can make a loud gurgling noise. This is usually the case when there is not good drainage under the floor, no sump pump or poorly operating sump pump. This is usually a temporary condition the will go away after a couple of day or in some cases a couple of weeks or so when the water table recedes to its normal level.
