What clients say
4.9 · 327 reviews
Our Sub-Zero column drifted warm before a dinner party. They diagnosed a failing evaporator fan, had the OEM part, and it held temperature perfectly the same evening.
Wolf oven stopped holding temperature. The technician explained the fault clearly, quoted it in writing, and replaced the part without a mark on the cabinetry. Genuinely professional.
Wine column was running warm and I assumed the worst. It turned out to be a clogged condenser and a tired fan — fixed for a fraction of what a replacement would have cost. Honest work.
