ASSET PROTECTION & COMPLIANCE

Prevent Inventory Loss Before System Lockout Occurs

A walk-in freezer failure during weekend service or holiday production leads to thousands of dollars in lost food inventory, health inspection scrutiny, and operational shutdown.

Our Red Seal 313A refrigeration mechanics perform thorough preventative maintenance inspections that uncover failing components before catastrophic lockouts occur. We measure operating superheat and subcooling, verify defrost cycle termination, test amp draw on all compressor phases, and clean condenser coils to keep head pressure within factory limits.

  • Quarterly Condenser & Coil Cleaning – Eliminates thermal insulating debris and reduces high-head pressure stress on compressors.
  • Refrigerant Charge & Operating Pressure Verification – Checks superheat/subcooling to verify correct metering and spot slow leaks early.
  • Electrical & Contactor Inspection – Checks for pitted contacts, loose terminal blocks, voltage drop, and capacitor health.
  • Defrost Cycle & Safety Control Calibration – Verifies high/low pressure cutouts, oil pressure safety switches, and defrost timers.
