Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Lonehill?
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.
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.
