WHY AN INDEPENDENT SPECIALIST

Why Sub-Zero® owners call an independent specialist

Specialist service for integrated and built-in units where a generic appliance visit usually isn’t enough.

Sub-Zero® and comparable premium built-in units. Independent service.

Book a diagnostic visit

This week, not next month

We schedule by the day, not by the quarter. Most Malibu and Conejo Valley visits are booked within the same week.

Diagnostic visit first. Findings before parts.

The person you call is the person who comes

AERIA is owner-operated. The technician who diagnoses your unit is the one who repairs it — no call center, no subcontractor hand-off.

Diagnostic visit first. Findings before parts.

Twenty-year-old units are our normal day

Series 500, 600, 700 and PRO 48, classic and integrated columns, undercounter drawers, wine storage. We keep long-serving Sub-Zero units running instead of talking you into replacing them.

WHAT WE FIX

What we fix

You don’t need to know what failed. These are the signs that usually justify a diagnostic visit.

We don’t quote repairs blindly over the phone. We don’t sell parts or give DIY guidance.

Book a diagnostic visit

Not holding temperature

Fridge or freezer side drifting warm, food spoiling early, “Service” or temperature alarm on the display.

These signs usually justify a diagnostic visit.

Frost or ice build-up

Frost on the evaporator or back wall, ice in the freezer drawer, doors that no longer seal.

These signs usually justify a diagnostic visit.

Ice maker stopped

No ice, hollow cubes, ice maker cycling without production, water valve or fill issues.

These signs usually justify a diagnostic visit.

Water on the floor

Drain line, condensate, water filter housing or line leaks under and behind the unit.

These signs usually justify a diagnostic visit.

Compressor or fan noise

Rattling, clicking, constant running, or a compressor that starts and stops.

These signs usually justify a diagnostic visit.

Condenser and airflow

Overheating, dusty condenser, fan failures on units that run in enclosed cabinetry.

These signs usually justify a diagnostic visit.

Door gaskets and hinges

Torn or hardened gaskets, doors out of alignment, integrated panels that no longer close flush.

These signs usually justify a diagnostic visit.

Wine storage and drawers

Wine columns and undercounter drawers with zone temperature or humidity faults.

These signs usually justify a diagnostic visit.

THE AERIA STANDARD

Clear findings first. The right repair second.

Built-in refrigeration is expensive to replace and worth diagnosing properly. The goal of the visit is a clear technical picture and a recommendation you can act on — not a guess, and not pressure.

REFRIGERATION REPAIR FAQ

Answers before the next step

Common questions about the diagnostic visit, brands we service, and what to prepare.

Independent specialist service for premium built-in refrigeration.

Are you authorized by Sub-Zero®?

No. AERIA Refrigeration is an independent service company and is not affiliated with, authorized by or endorsed by Sub-Zero Group, Inc. If your unit is still under manufacturer warranty, the manufacturer’s service network may be the right first call. For everything after that, independence is why we can come this week and quote a fixed price.

What does the $145 cover?

A full diagnostic of the unit and a written estimate with the exact repair price. It is credited toward the repair when you approve it.

Do you use original parts?

We source replacement parts that match your specific model and serial, from the same supply channels used across the industry. Every part is listed on your written estimate before we order it.

How old a unit can you repair?

Units from the 1980s onward are routine. Where a part is no longer available, we tell you before any work, in writing.

How fast can you come?

Calls are answered 24/7. Visits are scheduled Monday–Friday, 9am–5pm; the earliest slot is confirmed when you book. Weekend visits can sometimes be arranged for urgent cases — ask when you call.

Is the repair guaranteed?

Yes. Repairs we perform carry a 12-month written warranty on the work and the parts we install.
