Heating, Air Conditioning, and Refrigeration Mechanics and Installers

B23A installation, operation, and maintenance of refrigeration and air conditioning equipment, including refrigerant recovery and recycling, directly overlap with civilian cooling-system service work.

How to prepare: Compile an equipment-specific service history for refrigeration and air conditioning applications, including records of the Section 608 Type I and II certification required by the B23A manual.

What the civilian work involves
  • Study blueprints, design specifications, or manufacturers' recommendations to ascertain the configuration of heating or cooling equipment components and to ensure the proper installation of components.
  • Discuss heating or cooling system malfunctions with users to isolate problems or to verify that repairs corrected malfunctions.
  • Connect heating or air conditioning equipment to fuel, water, or refrigerant source to form complete circuit.
