Duct inspection costs can vary depending on the size of your home, the accessibility of your ductwork, and whether additional testing (like airflow diagnostics or thermal imaging) is needed. At Radiant, we offer transparent pricing and will walk you through what to expect before we begin. In many cases, an inspection is included as part of a broader HVAC service visit or tune-up. For homeowners in Austin and San Antonio, a duct inspection is a smart, cost-effective first step to diagnosing airflow or efficiency problems.
