Which Sub-Zero appliances do we service?

All Sub-Zero Lines: Built-in, Classic, Designer & wine preservation units, fully covered.

Fridge & Freezer

Sub-Zero Refrigerator Repair in Dallas

Sub-Zero refrigerators use a dual-compressor design that cools the fresh-food and freezer sections independently, and they’re built for decades of service. Because the two circuits are separate, one section warming while the other holds points to a specific compressor or evaporator fault — a useful diagnostic shortcut. Frost buildup, a unit running constantly, or a temperature alarm despite feeling cold each trace to different components. Built-in and integrated units sit flush in cabinetry and need careful access. We use genuine Sub-Zero parts and follow manufacturer procedures.

Sub-Zero Freezer & Column Repair in Dallas

Sub-Zero freezer columns and drawers are precision units. A column that won’t hold temperature usually has an evaporator fan or defrost fault; an ice maker that won’t produce points to the water inlet valve or fill tube; frost accumulation means a defrost heater or door gasket; and a loud unit is usually a fan motor bearing. We service columns, drawers, and built-in freezers with manufacturer-specific care.

Sub-Zero Wine Storage Repair in Dallas

Sub-Zero wine preservation units hold precise dual-zone temperatures, and a drift in either zone puts a collection at risk. A zone that won’t hold temperature traces to a sensor, thermostat, or compressor; condensation inside points to a door seal or humidity control; and a unit running constantly usually means the coils or seals. We protect your collection with careful, precise service and genuine parts.

Recently Completed Repairs

Sub-Zero 648 Built-In – Freezer Side Warming

Preston Hollow, Dallas

The problem: The dual-compressor built-in had a freezer section creeping above temperature while the refrigerator side held perfectly — the independent design pointed clearly to one circuit.

The fix: The freezer evaporator fan motor had failed, stopping cold-air circulation on that side only. Carefully accessed the unit within its cabinetry, replaced the OEM fan motor, and confirmed full temperature recovery on the freezer circuit before refitting flush. On site: 3 hours.

Sub-Zero Refrigerator Column – Frost Buildup

Bent Tree, Dallas

The problem: A built-in refrigerator column had developed frost on the interior back wall and was no longer holding a steady temperature.

The fix: The defrost heater had failed, letting frost accumulate on the evaporator. Manually cleared the ice, replaced the OEM defrost heater and thermostat, and verified the defrost circuit cycled correctly before reloading. On site: 2.5 hours.

Sub-Zero Wine Unit – Zone Won’t Cool

Glen Lakes, Dallas

The problem: The lower temperature zone of a dual-zone wine unit had drifted warm, putting a collection at risk.

The fix: A failed zone sensor was feeding bad data to the control board, so the compressor wasn’t cycling for that zone. Replaced the OEM sensor, confirmed the compressor and refrigerant circuit were healthy, and verified both zones held their set temperatures. On site: 2 hours.

Our reviews

Fast, polite, and the price matched the quote exactly. Can’t ask for more than that.

Came home to a fridge full of warm food and honestly thought we’d be buying a new one. Booked online that evening and someone was out the next morning. Turned out to be a small job and he had it cold again before lunch.

What I liked most is he didn’t talk down to me. Explained what was wrong in plain English and showed me so I’d know if it happened again.

Called three places about our washer leaving a puddle every morning. Only one called back the same day. Sorted in one visit and the floor’s been dry since.

Such a relief. The oven had been on its last legs for weeks and I kept putting off calling. Wish I’d done it sooner.

Showed up on time, wore shoe covers, cleaned up after. Tidy work and a fair bill.

The dryer was taking three goes to dry a single load and driving us up the wall. He found the problem quickly, didn’t try to upsell me on anything, just fixed what needed fixing. Working like new now.

Honest is the word I’d use. Told me one repair wasn’t worth the money on an older unit and pointed me in the right direction instead of just taking the job. Rare these days.

Booked at 8 in the morning and it was done by early afternoon. Same day, no fuss.
