How Radon Air Systems Help for a Healthier Home Environment
Radon air systems pull radon gas from under the concrete floor of your home through a fan driven venting system made out of PVC pipe. The fan is a low wattage device similar to a bathroom fan except it is very quiet. There’s virtually no maintenance with radon air systems.
Limitations of Passive Radon Venting
“Passive radon venting” is sometimes suggested as a solution to remove radon from under the slab of your home. This is essentially a radon removal system without the fan. Unfortunately, passive sub slab radon venting doesn’t work because a fan is required to create negative pressure in the ground that will push air under the slab out the vent pipe.
Installation and Cost of Radon Venting
There is not much cost difference between a sub slab radon venting system with or without a fan. The difference is one works and the other one doesn’t. When a fan is installed, it must be installed outside, in the attic, or an unfinished garage. It should not be installed in the basement or anywhere inside the home because a frozen or plugged vent can cause the radon to be discharged back into the house through the fan unit.
