After a low-GWP conversion, which documentation should be completed?

• A. Just the date of service
• B. Documentation including all steps, test results, final charges, and notes
• C. Only the final refrigerant name
• D. Photos of the equipment

Answer: (B)

After a low-GWP conversion, you should document the entire process: every step performed, the test results from system performance and leak checks, the final refrigerant charge amount, and any notes about equipment changes or issues. This complete record shows that the conversion was done correctly, that the right low-GWP refrigerant was installed and charged to the proper quantity, and that the system passed safety and performance checks. It also provides a reference for future service and supports warranty and regulatory compliance. Merely recording a date, or just the final refrigerant name, or a collection of photos misses crucial evidence of what was done and how the system behaved, which is why a full set of documentation is required.
