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.

Approach

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 compares measured box and product temperatures with airflow, coil condition, defrost behavior, door sealing and control response. The equipment and observed pattern determine the sequence; a warm cabinet alone does not establish the failed component.

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.

FAQ

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?+

A warm room alone does not identify the compressor. Condenser condition, evaporator airflow, defrost behavior, door sealing and controls are checked alongside measured temperatures before a 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.
