  "description": "American Radon Systems is a state licensed, owner-operated radon mitigation company based in Tinley Park, Illinois, serving Chicago's south and southwest suburbs. The focused service area includes Tinley Park, Frankfort, Mokena, New Lenox, Manhattan, Orland Park, Orland Hills, Palos Park, Palos Heights, Oak Forest, Lemont, Homer Glen, Lockport, Crest Hill, and Shorewood. More than 10,000 radon systems installed. Nearly 25 years of combined radon mitigation experience. Bill personally evaluates each home before the system is designed and quoted. Jose is an experienced lead installer known for clean pipe routing. We install radon mitigation systems, activate builder-installed passive systems, replace radon fans, relocate and reroute existing systems, and repair systems including those installed by other companies. Five-year complete fan replacement coverage: if a fan we install fails during the first five years, the service visit, labor, and replacement fan are included at no cost to the homeowner. We do not sell radon testing; we publish testing education and refer homeowners to licensed measurement professionals. Illinois license RNM2018212.",
