Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Chartwell?
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 often should a commercial ice machine be descaled?
On the water hardness common across Sandton, every four to six months for a busy commercial machine and at least annually for a low-duty home or office unit. We leave a dated descale and sanitise record you can produce at a health inspection.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
