Delaware Master HVACR Restricted License (DE) Delaware’s restricted license path focuses narrowly on EPA Section 608 refrigerant handling—not general HVAC installation or repair. This focused scope means you’re mastering containment protocols, leak detection thresholds, and certification-specific regulations rather than wiring diagrams or ductwork. The restriction itself is the distinction contractors can legally handle refrigerant without broader licensing overhead, making it an efficient credential for specialized technicians.
