What is required for A2L refrigerants, immediately after repair?

• A. Leak test and pressure test the system
• B. Visual inspection only
• C. No testing required
• D. Electrical safety test

Answer: (A)

After repairing an A2L refrigerant system, you must verify both that there are no leaks and that the system can safely hold pressure. A2L refrigerants are mildly flammable, so ensuring there’s no leakage is crucial to prevent ignition risks, and confirming the system integrity with a pressure test helps catch any weaknesses in components or connections before recharging. Visual inspection alone can miss small or latent leaks, and skipping testing or focusing only on electrical safety doesn’t address the core safety concerns with these fluids. Together, leak testing and pressure testing provide the necessary assurance that the system is safe to operate with an A2L refrigerant.
