True or False: A technician must hold Type III (or Universal) certification to legally maintain, service, repair, or dispose of a low-pressure chiller.
Not quite. The answer is A: True
Certification under Section 608 is category-specific. Low-pressure appliances require a Type III technician, and Universal certification (which covers Types I, II, and III) also qualifies. Type I or Type II alone does not authorize work on a low-pressure chiller. Every certification exam includes the Core group of questions plus the questions for the specific type.

Checked against the official text
Read the eCFR text current through 2026-10-30 of § 82.161. Persons who maintain, service, repair, or dispose of low-pressure appliances must be certified as Type III technicians; Universal certification covers all types.
