Can't Call Right Now?

Leave your info any time — if it's outside service hours, we'll follow up and get you on the schedule for your next convenient day.

Not sure? The data tag is inside the freezer, top-left as you open the door — model and serial are on it. If the unit is only a year or two old it is probably still under Sub-Zero warranty and that repair should be free through them. We will tell you so rather than take the trip.

Sub-Zero Issues We Fix Daily

Not Cooling Properly

Condenser coils, evaporator fan, thermostat or sealed system issue. Most common Sub-Zero complaint.

Ice Maker Not Working

Water inlet valve, ice maker module, or frozen water line. We carry common parts.

Loud Compressor Noise

Clicking, humming, or knocking from the compressor. Early diagnosis saves major cost.

Error Codes / Alarm

EC 01–EC 50 codes. We diagnose the root cause, not just clear the code.

Water Leaking

Clogged defrost drain, door gasket failure, or water line issue.

Frost / Ice Buildup

Defrost system failure — heater, thermostat, or timer. We fix the cause, not the symptom.

What These Faults Actually Look Like

An evaporator sealed in ice behind the rear panel. The unit was still running — that is exactly why the owner assumed the compressor was fine and the problem was something else.

Why “still running” misleads people

A Sub-Zero with a defrost fault keeps humming, the condenser keeps turning, and every light behaves. Nothing announces a failure. Meanwhile the coil is bridged with frost and moving no air at all, so one compartment climbs while the other stays cold.

Which is why we take temperatures in the compartment rather than trusting the display, before anyone opens a sealed system.

Your Kitchen Gets Put Back the Way It Was

Built-in side-by-side refrigerator back in its cabinet opening after a service call, floor protection still in place
End of a call: unit back in its opening, trim reseated, floor covering still down until we leave.
Sealed-system equipment and a Sub-Zero parts box staged on floor protection in a residential kitchen during a repair
Recovery machine, gauges, nitrogen, torch — and a Sub-Zero parts box. Sealed-system work happens here, in your kitchen, not at a subcontractor’s shop next week.

A Sub-Zero column is fitted to a cabinet opening, often with a custom panel on the door. Getting it out and back without marking the surround is a real part of the job — and the part a general appliance tech is usually not set up for. Floor protection goes down before anything moves.

Sub-Zero branded food storage guide card removed from a built-in refrigerator during a service call
The storage guide out of a Sub-Zero door. Small thing — but everything that comes out of the unit goes back where it belongs.

Yes — Southlake and Highland Park are our primary service areas. Same-day service available. Also covering Westlake, Colleyville, University Park, Flower Mound, and all DFW.
