Sub-Zero Repair in Los Angeles
Factory-trained technicians for every Sub-Zero refrigerator, freezer, and wine storage unit in Greater Los Angeles.
Your Sub-Zero wasn't a casual purchase. It was a $10,000+ investment in a machine built to last decades, and it deserves a technician who actually understands how it works. Arctic Cool Refrigeration has been servicing Sub-Zero units across Los Angeles since 1984. Our technicians know these machines inside and out — the dual-compressor systems, the sealed-system architecture, the microprocessor controls that most general appliance shops won't touch.
We work in homes throughout Beverly Hills, Malibu, Calabasas, Bel Air, and Pacific Palisades where Sub-Zero is the standard, not the exception. We show up on time, we protect your floors and countertops, and we keep the process quiet and professional. No logos on the truck. No drama.

- PRO Series (PRO 36, PRO 48) — stainless-steel professional units
- 500 Series (501R, 532, 550) — legacy models from the 1990s still running strong in older homes

- Wine Storage (BW-30, UW-24) — dual-zone and undercounter wine preservation units
- Undercounter (UC-24, ID-30) — compact drawer refrigerators and freezers
Common Sub-Zero Problems We Fix
Not Cooling or Warm Fridge Side
Usually a condenser fan motor, dirty coils, or a sealed system issue. Sub-Zero's dual compressor means one side can fail independently.
Ice Buildup in Freezer
Defrost timer, heater, or thermostat failure. Common on 500/600 series models. Left unchecked, it blocks the evaporator.
Loud or Unusual Noises
Worn evaporator fan bearings, a failing compressor, or a condenser fan hitting debris. We pinpoint and replace the exact component.
Water Leaking on Floor
Clogged drain tube (extremely common on older Sub-Zeros), cracked drain pan, or a failed water inlet valve on ice maker models.
Control Board Errors
Flashing lights, error codes, or unresponsive touchpads. We diagnose and replace Sub-Zero control boards with OEM parts.
Door Seal Deterioration
Worn gaskets let warm air in, forcing the compressor to overwork. We carry replacement gaskets for most Sub-Zero models.
Why LA Homeowners Trust Us with Their Sub-Zero
Sub-Zero repair is not general appliance repair. These units have hermetically sealed systems, proprietary control boards, and build tolerances that require specific training and tools. A technician who works on Kenmore all day and occasionally sees a Sub-Zero is going to struggle with your unit. Our guys work on Sub-Zeros every single week — in some of the most expensive kitchens in Los Angeles.
We carry manufacturer-spec parts on every truck. We diagnose accurately on the first visit. And we've been doing this for over 40 years, backed by 847 five-star reviews from homeowners who expect nothing less than perfect.
Serving Sub-Zero Owners Across Los Angeles
We dispatch from Calabasas and cover every neighborhood where Sub-Zero units are common: Beverly Hills, Bel Air, Malibu, Pacific Palisades, Brentwood, Encino, Tarzana, Hidden Hills, Westlake Village, and Thousand Oaks. Same-day service is available seven days a week — because your Sub-Zero doesn't care what day it decides to stop cooling.
Frequently Asked Questions
How much does Sub-Zero repair cost in Los Angeles?
Sub-Zero repair typically costs between $350 and $1,500 depending on the issue. Thermostat or control board replacement runs $350 to $700. Sealed system or compressor repair ranges from $800 to $1,500+. We provide a written estimate before starting any work.
Do you carry Sub-Zero parts on your trucks?
Yes. Our technicians stock the most commonly needed Sub-Zero parts including thermostats, door gaskets, fan motors, control boards, and water filters. For less common components, we source and install within 1-2 business days through our direct parts suppliers.
Why is my Sub-Zero refrigerator not cooling properly?
The most common causes are dirty condenser coils, a failed evaporator fan motor, a worn door gasket, or a refrigerant leak in the sealed system. Sub-Zero's dual-compressor design means the fridge and freezer operate independently — if only one side is warm, it narrows the diagnosis. Call us at (800) 685-5590 for same-day diagnosis.
Can you repair older Sub-Zero models like the 500 series?
Absolutely. We service every Sub-Zero model ever made, including the classic 500 series, the 600 series, and all current Classic, Designer, and PRO units. Many 500 and 600 series refrigerators from the 1990s are still running strong. We have access to parts for discontinued models that most shops can't source.
Is Sub-Zero repair worth it or should I replace the unit?
Sub-Zero refrigerators are almost always worth repairing. A new built-in starts around $9,000 and can exceed $20,000 for larger configurations. These units are engineered for a 20+ year lifespan, so even a $1,500 compressor replacement is a fraction of replacement cost. We'll give you an honest assessment every time.
