HVA 110 - Basic Refrigeration

Description
Students learn the basic theory of refrigeration system operation by classroom study as well as performing basic service operations on completed systems including refrigerant recovery, leak test, evacuate, and recharge. Students also perform basic refrigeration-grade tubing connections including soft solder, phos-copper brazing alloy, silver solder, and flaring. There is a tool purchase requirement for this introductory HVACR course.
