Industry context
Warehouses
For warehouses, refrigeration reliability is a commercial requirement rather than a convenience. Distribution cold storage holding palletised perishable stock. We plan the fix to end the risk, not just the symptom.
Cape Town coverage
Wellington · Winelands
Our Winelands technicians treat Wellington as core coverage rather than an outlying callout. From first call to cold cabinet, the Wellington leg of the job is the shortest part.
Prevention
Stop the fault returning
Keep condenser fins clean and airflow clear — the leading preventable cause of thermostat fault in warehouses cold chains.
Monitor cabinet temperatures daily and log deviations so thermostat fault is flagged before stock is lost.
Replace door seals at the first sign of perishing to stop the warm-air ingress that drives many thermostat fault callouts.
Book a service check ahead of peak trading so the walk-in cooler under the heaviest load is not the one that fails.
