Common questions

Can a built-in Sub-Zero be repaired without removing the joinery in Montecasino Precinct?

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.

Can you just top up the gas in my ice machine?

No: a machine low on refrigerant has a leak, and topping up hides it. We leak-trace electronically and under nitrogen, repair the joint, fit a new drier, pull a deep vacuum and weigh in the exact plated charge.

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.
