Before you apply
Confirm how border-crossing travel, on-call duty, and vehicle use are handled.
Match your experience to the refrigerant, equipment, controls, and repair duties named in the posting. EPA Section 608 certification matters when work could release regulated refrigerant from an appliance; it is not a blanket credential for every role.
For ammonia systems, ask about site training and safety duties. OSHA process-safety requirements depend on the system and its ammonia quantity; confirm the facility's requirements.
Compare base pay with overtime, shift premiums, call pay, travel time, vehicle, tools, and training.
