Condenser fan bearing repair for chiller in San Jose, CA

Commercial HVAC / Chiller Diagnosis & Repair – Restoring Cooling System Performance

The customer contacted us after their commercial chiller suddenly stopped working. For any business, this type of breakdown is critical because a failed cooling system can affect comfort, operations, and equipment that requires stable temperatures.

Our technicians arrived on site and performed a complete inspection of the equipment. As always, diagnosis is free with repair, allowing the customer to understand the issue before approving service. During the inspection, we identified the cause of the shutdown — a failed condenser fan head bearing.

Although this may seem like a small component, the fan bearing is essential for proper airflow and heat rejection. Once worn out, the fan can become noisy, unstable, or stop entirely, causing overheating and system failure.
