Reliable Fairmount Radon Mitigation

The clearest sign that a radon fan needs replacement is when it stops running entirely, which you can confirm by checking the manometer and listening for motor noise. Other warning signs include excessive humming or grinding, significantly reduced suction on the manometer, or radon test results that have climbed above 4 pCi/L despite the fan appearing to run. Age is also a factor, as fans over 10 years old are statistically more likely to fail and may be worth proactively replacing even before issues arise.

Yes, radon fans can be installed on the exterior of a home, provided the fan model is rated for outdoor use and adequately protected from the elements. Exterior installation has the safety advantage of ensuring that any minor leakage from the fan housing vents outside rather than into the living space. However, outdoor fans in cold climates may be subject to moisture intrusion, freezing, and accelerated wear if not properly weatherproofed.

In most cases, standard homeowners insurance policies do not cover radon system repair or fan replacement, treating it as routine home maintenance rather than an insurable loss. However, if the fan was damaged by a covered event, such as a storm, fire, or flooding, a portion of the repair costs may be eligible for reimbursement. It is always worth reviewing your specific policy and speaking with your insurance agent to clarify coverage. Some home warranty plans do cover radon system components, so that is another avenue worth exploring when purchasing a home.
