DC Master Refrigeration and Air Conditioning Mechanic Limited (322) DC’s 322 exam uniquely balances theoretical thermodynamics with hands-on troubleshooting of residential and commercial HVAC systems in real-world climates. Unlike broader certifications, it demands fluency in EPA refrigerant recovery protocols, ductwork diagnostics, and the specific building codes that govern the District’s high-density urban environment—skills rarely bundled together at the journeyman level.
