Common questions

Can a built-in Sub-Zero be repaired without removing the joinery in Sandton CBD?

In most cases yes. The units are designed to be serviced from the front through the grille and toe panel; full de-racking is only needed for sealed system work.

How quickly can a coldroom be back at temperature?

Once the fault is cleared, a well-insulated coldroom pulls back down within two to four hours. We advise on stock protection during that window.

Can you work after trading hours?

Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
