Reliable Frederick Radon Mitigation

Not necessarily. While fan failure is a common cause of lost suction, there are several other possibilities that should be investigated before assuming the fan needs replacement. A disconnected or cracked pipe joint can allow air to leak in and equalize pressure, giving the appearance of fan failure even when the motor is running. A clogged suction pit beneath the slab, a newly opened sump pit, or a large foundation crack can also reduce system pressure significantly.

A radon fan typically fails due to bearing wear and tear over time, as these fans run continuously 24/7. Moisture and condensation buildup inside the vent pipe can also drain back into the fan housing, causing the motor to short-circuit or rust. Additionally, debris like leaves or twigs entering the pipe, electrical surges, or extreme weather conditions can burn out the motor or seize the fan blades.

Radon fans installed in unconditioned spaces like unheated garages or exteriors can be exposed to extreme cold, which can affect fan performance and longevity over time. While most quality fans are designed to operate in cold temperatures, condensation from the exhaust air can freeze inside the pipe in very cold climates, potentially blocking airflow or damaging the fan. In regions with harsh winters, it is advisable to use a fan model specifically rated for cold-weather operation and to ensure the exhaust pipe termination is positioned to prevent ice buildup. Insulating exposed sections of pipe can also help reduce condensation-related issues in cold climates.
