Don’t Let a Broken Freezer Ruin Your Week
Expert Sub-Zero freezer repair in Mountain View to protect your frozen investments.
Frequent Freezer Failures We Resolve
Our technicians possess extensive, hands-on experience with the specific mechanical and electronic issues common to Sub-Zero freezers.
Heavy Frost Buildup
This is a tell-tale sign of a system imbalance, often caused by failing door gaskets, a faulty defrost heater, or a malfunctioning defrost thermostat. We isolate the component and replace it to restore the automatic defrost cycle.
Temperature Swings
Inconsistent temperatures jeopardize your food. This often points to a dirty condenser coil, a failing evaporator fan motor, or more complex issues within the sealed system, such as a refrigerant leak, which requires expert handling.
No Power or Not Running
A dead unit can range from a simple electronic control board issue to a more complex problem with the compressor's start relay or the overload protector. We perform systematic electrical tests to find the precise point of failure.
Our Technical Approach to Freezer Repair
What We Do on the First Visit
Our primary objective is a single-visit resolution. We arrive with service vehicles stocked with common Sub-Zero freezer parts. The initial visit always includes:
- Full diagnostic testing of the sealed and electrical systems.
- Checking for refrigerant leaks using sensitive electronic detectors.
- Verifying the functionality of all fans, motors, and temperature sensors (thermistors).
- Providing a detailed diagnosis and a firm, flat-rate quote for the repair.
When a Second Visit is Needed
While we strive for one-visit repairs, certain complex issues or non-stocked parts may necessitate a follow-up:
- If a major sealed-system component like a specific compressor or evaporator coil needs to be special-ordered.
- For extensive sealed system repairs (e.g., leak repair and recharge) that require specialized workshop equipment.
- If custom-ordered electronic or cosmetic parts for older, vintage Sub-Zero models are necessary.
Commonly Replaced Freezer Parts
Our deep experience means we can quickly identify and replace failing components to restore your freezer's function and efficiency.
Our Approach to Older Models
Sub-Zero freezers are built to last for decades. For these valued vintage models, parts can be scarce. We maintain access to an extensive network of parts suppliers to source hard-to-find components. If a part is truly obsolete, we provide an honest assessment of the situation. We'll discuss potential modern retrofitting options or advise when a full replacement is the more sensible long-term investment.
