Heating, ventilating, air conditioning and refrigeration (HVACR) service technicians install, maintain and repair heating, ventilation, air conditioning and refrigeration systems in industrial, commercial and residential buildings.

Some technicians specialize in one type of specific system, while others are versatile and work on multiple systems. Apprentices in the HVACR trade study and work in all systems.

The UA Local 100 JATC training program provides our apprentices with a high-quality classroom education to help them learn their trade. They also receive mandatory OSHA safety training to keep them safe on the jobsite. During the apprenticeship, you will reinforce what you learn in the classroom by working everyday in the field bridging the gap between knowing and doing.
