Hi, has anyone ever had the air quality tested in their home? I'm not necessarily worried about mold, but I sometimes smell something in my son's room (not bad-smelling, but I can't pinpoint what it is), and now I'm paranoid that fumes may be getting in there from our garage. DH thinks I'm being paranoid as usual, but I'd like some peace of mind.

If you've had the air quality tested in your home, who did you use? What did they test for? Did they try to sell you something? TIA!
