Refrigeration Jobs in Knoxville, TN

Knoxville, TN supports a strong commercial refrigeration market driven by grocery chains, food service operators, and distribution facilities. Refrigeration technicians service commercial refrigeration equipment — walk-in coolers, freezers, reach-in display cases, and ice machines in grocery stores, restaurants, and distribution centers. Employers typically require EPA 608 certification and experience with the refrigerant circuits, electrical controls, and defrost systems common to supermarket and restaurant equipment.

Refrigeration technicians in Knoxville, TN often cross over between commercial refrigeration and HVAC service, which broadens their value to employers who run mixed service departments. EPA 608 Universal is the baseline certification; experience with specific OEM systems — Hill Phoenix, Tyler, Hussmann, or Manitowoc — is a differentiator that can meaningfully increase hourly rates. Night and weekend availability is often required given the emergency nature of refrigeration failures.
