Built-in refrigeration, ranges and dishwashers, repaired by technicians who work on these systems every day — and who check whether the opening still holds square before they quote you a part.
Refrigeration is what Sub‑Zero builds and what we work on most. Every unit gets a technician who has seen the same sealed system before.
Sub‑Zero builds refrigeration and nothing else, and the engineering that follows from that is where generalist appliance training runs out.
Each of these has its own diagnosis page — what causes it, what it usually costs, and whether it is worth repairing.
The Las Vegas Valley Water District publishes hardness at 16 grains per gallon, 591 ppm of dissolved solids, and a saturation index of +0.25. That last number is the one that matters. A positive index means the supply is actively scale-forming — it deposits mineral rather than dissolving it.
Anything that heats or concentrates water pays for that. An ice maker, a dishwasher heating element, a steam-oven boiler: each one is doing its job against water that is trying to leave mineral behind on every cycle. It is why ice production tapers off rather than stopping, why spray arms block, and why a steam oven that is descaled on the manual's relaxed schedule still furs up.
And the air is as dry as the water is hard. Afternoon humidity averages 21% across the year and 11% in June. Door gaskets harden and lose their set years early in air that dry — and a stiff gasket passes a visual check while still leaking, which is the single most common thing we are called out to.
The same technicians work across the rest of the built-in market, so a kitchen with three different badges in it takes one visit rather than three.
Two housing stocks in one city -- 1950s and 60s estate enclaves near downtown on half- to full-acre lots, and 1990s-to-2020s Summerlin production and custom homes out west. Older stock means older built-ins, and a fifteen-year-old sealed system fails differently from one still under warranty.
