When dealing with old refrigerant, it is crucial to ensure it is safe and effective for continued use. Testing or disposing of it according to local regulations is the appropriate practice. This approach serves two main purposes: first, it verifies the condition and purity of the refrigerant, which is essential for maintaining system efficiency and preventing potential damage to HVAC equipment. Second, refrigerants can pose environmental hazards if they are contaminated or improperly handled, so adhering to local regulations ensures compliance with environmental protection laws and safety standards.

This method respects the best practices for safety and environmental responsibility. Without testing, there is a risk of using refrigerant that may not function properly or may even contribute to system failures or harmful environmental impacts. Proper disposal, if the refrigerant is deemed unusable, also mitigates the risk of venting harmful gases into the atmosphere.
