Should I test for radon or mold in Arizona?
Radon is generally not a significant concern in Arizona because our soil and geology produce low radon levels compared to other parts of the country, and testing is rarely done here. Mold testing is more relevant, especially in homes with past water damage, older HVAC systems, or poor ventilation. Visible mold, water stains, musty odors, or a history of leaks are reasons to consider testing or a specialized mold inspection. Arizona's dry climate reduces mold risk compared to humid areas, but it can still develop in bathrooms, under sinks, or around evaporative coolers. The specifics depend on your situation and a licensed inspector should confirm, and Jon can connect you with one.
