A day in the life of a refrigeration service tech provides a lot of different tasks — tasks that include working with a variety of refrigerants. And Troy Singer has seen his fair share of refrigerants in his brief career as a supermarket refrigeration/HVACR service technician apprentice for Fazio Mechanical Services of Pittsburgh.
The third-year technician said his workload is around 70 percent supermarket refrigeration and 30 percent HVAC. “We also have some light commercial accounts that include gas stations with walk-ins, ice machines, and reach-ins,” Singer said.
