Diagnosing refrigerant leaks involves:

Visual Inspection: Look for oil stains o r greasy spots around the A/C components compressor, condenser, hoses, which can indicate refrigerant leaks.
UV Dye and Leak Detection Kits: Use a UV dye kit, which is added to the refrigerant. A special UV light will highlight any leaks.
Pressure Test: A refrigerant pressure test can help determine if there’s low pressure in the system, which would point to a leak.
Listen for Hissing: A hissing sound near the A/C components could indicate a refrigerant leak.
