Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Killarney?
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.
What temperature and humidity should a wine cellar hold?
Twelve to fourteen degrees Celsius at 60 to 70 percent relative humidity. Drift outside that band usually means a failed humidistat, a leaking vapour barrier or a unit sized for a smaller cellar.
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.
