Commercial Refrigeration Repair in San Jose
Independent diagnostics and repair for the cold side of San Jose kitchens and retail — walk-ins, reach-ins, prep tables, display cases and ice machines.
How KONGRA approaches the diagnostic
Refrigeration problems carry an inventory cost the moment they start, so the priority is an accurate answer quickly: what temperature the box is actually holding, and which system is responsible.
The diagnostic measures box and product temperature, evaporator and condenser airflow, coil and defrost condition, door sealing and control behavior — in that order, because most warm-box calls resolve there.
Only when measurements point to the sealed system do we evaluate compressor and system performance, and any refrigerant work is performed within KONGRA's legal scope or coordinated with licensed independent contractors.
For operators, each visit produces documentation: measured values, findings, options and preventive recommendations such as condenser cleaning intervals and gasket replacement.

Real equipment, documented diagnostics
Evaporator coil frost pattern documented during refrigeration inspection. Root cause requires on-site measurement.
Commercial Refrigeration Repair
Commercial cuber ice bin and distribution area documented during inspection. Ice appearance alone does not establish performance.

Frequently asked questions
What refrigeration do you cover in San Jose?+
Walk-in coolers and freezers, reach-in and undercounter cabinets, prep tables, display cases and commercial ice machines.
Our walk-in is warm — is it the compressor?+
Usually not first. Condenser condition, evaporator airflow, defrost behavior, door sealing and controls are measured before any sealed-system conclusion.
Do you perform refrigerant work?+
Refrigerant and sealed-system work is performed only within KONGRA's legal scope or coordinated with properly licensed independent contractors.
