In Pennsylvania, the passive parts of a radon system last decades while the fan typically runs 5-15 years. Here is the EPA-sourced lifespan, maintenance cadence, and replacement cost — tuned to PA's high-radon geology.
Pennsylvania's Real Estate Seller Disclosure Law (68 Pa. C.S. §§ 7301-7315) — administered through the Pennsylvania Real Estate Commission and codified in 68 Pa.

The Reading Prong — a Precambrian uranium-bearing gneiss-and-granite belt running through Berks, Lehigh, Northampton, Bucks, Montgomery, and Chester counties — is the geological reason eastern Pennsylvania has some of the highest residential radon readings in America.

In December 1984, a Berks County construction engineer named Stanley Watras set off radiation alarms entering the Limerick Nuclear Power Plant — where he worked. The contamination traced not to the plant but to his home: a Boyertown, PA house with an indoor radon level of approximately 2,700 pCi/L, the highest US residential radon reading ever recorded. This single Pennsylvania discovery created the modern American radon industry.
