My work is local. My mission doesn't have to be.

I’m Bill, owner of American Radon Systems. My team works with homeowners in a small part of the Chicago area. I created these guides to help more families understand their radon-testing options, wherever they live.

One idea I believe in is sharing a reusable monitor. Use it in your home, then lend it with the right instructions to someone you care about. You don’t have to buy anything through this site to use the information.

American Radon Systems

American Radon Systems is based in Illinois and serves Chicago’s south and southwest suburbs. These educational guides help homeowners understand radon-testing options beyond our installation area.

How these guides are supported

When you buy through our link, we receive a small percentage of the sale. That helps us keep building these guides and spreading the word about radon testing to more families.

You buy directly from Airthings on its official website. The customer’s 10% discount is separate from our referral income. These are independent homeowner guides, not government websites or Airthings-operated stores. Product sales and warranty support are handled by the merchant and manufacturer.

Use the local kit resources and testing help whether or not you shop through a link. The sources page lists official guidance and manufacturer instructions.
