What HVAC inspections are required by code?

HVAC inspections required by code include annual inspections per International Mechanical Code (IMC) and local building codes, ASHRAE Standard 180 maintenance requirements for commercial buildings, EPA Section 608 refrigerant handling compliance checks, and fire damper inspections per NFPA 80 (every 4-6 years). Many jurisdictions require permits and inspections for new installations, major repairs, and refrigerant system modifications.

How often should HVAC be inspected?

HVAC systems should be inspected at minimum twice per year, once before cooling season and once before heating season. ASHRAE Standard 180 recommends quarterly filter inspections, monthly operational checks for commercial systems, and annual comprehensive inspections covering coils, ductwork, controls, and refrigerant levels. Critical environments like hospitals and data centers may require monthly inspections.
