Effective Erie Radon Mitigation

This isn't recommended. It's important to understand that an improperly installed fan can result in poor radon reduction, foundation over-depressurization, or even an unsafe exhaust configuration. Many states require radon mitigation work to be performed by a certified contractor, so checking local regulations before proceeding is essential.

Installing an undersized fan is the most common mistake, resulting in insufficient suction to keep radon levels below the EPA's recommended action level of 4 pCi/L. On the other end of the spectrum, an oversized fan can create excessive negative pressure beneath the foundation, potentially causing backdrafting of combustion appliances like furnaces, water heaters, or fireplaces. Backdrafting is a serious safety concern because it can draw combustion gases, including carbon monoxide, into the living space. Always verify system performance with a manometer and conduct a radon test after any fan replacement to confirm safe and effective operation.

A grinding noise coming from the radon fan is a strong indicator that the motor's internal bearings are failing and the fan is nearing the end of its useful life. Bearing failure is a common cause of radon fan death and typically worsens over time until the motor seizes completely. Continuing to run a fan with failing bearings can cause the motor to overheat and potentially create a fire hazard, so prompt replacement is strongly recommended.
