Connecticut Limited Warm Air, Air Conditioning and Refrigeration (D-1, D-2) Connecticut’s D-1 and D-2 licensing exams demand rigorous mastery of refrigerant thermodynamics, compressor mechanics, and EPA compliance standards. Test-takers often underestimate the depth required on psychrometric charts, pressure-enthalpy diagrams, and troubleshooting multi-stage systems. Technical calculations dominate, alongside code interpretation questions that blur the line between theory and real-world application.
