A required listing, test report, certification, or compliance document is absent from the submittal package.

## What to look for in Division 23 Heating, Ventilating, and Air Conditioning (HVAC)

Required certifications in HVAC submittals:
- **AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certification** - the gold standard for HVAC equipment capacity verification. Absence of AHRI certified rating is a common blocker.
- **UL listing** (UL 1995 for HVAC equipment, UL 181 for duct systems, UL 555/555S for fire/smoke dampers)
- **ASHRAE 90.1 compliance** (energy efficiency requirements)
- **ASHRAE 62.1 compliance** (ventilation/IAQ)
- **AMCA (Air Movement and Control Association)** certification for fans and dampers
- **SMACNA (Sheet Metal and Air Conditioning Contractors' National Association)** compliance for duct construction
- **NFPA 90A** compliance (air conditioning and ventilation systems)
- **Seismic certification** (IBC Chapter 13, ASCE 7, OSHPD for California)
- **Sound test reports** per AHRI Standard 260/270/370
- **Factory performance test** reports for chillers, AHUs, cooling towers
- **TAB (Testing, Adjusting, and Balancing)** agency certification (AABC, NEBB, or TABB)
- **EPA Section 608** certification for refrigerant handling
- **Buy America / Buy American** compliance documentation
- **LEED documentation** - refrigerant GWP calculations, energy modeling inputs
- **Warranty documentation** - compressor warranty terms, parts/labor coverage period

## Severity

Default grade: Fix and Resubmit. Escalates to Blocker when the missing document is a code or life-safety requirement (UL listing, fire rating).
