Do you service both air-cooled and water-cooled chillers?

Yes, including the cooling towers, pumps and controls that support water-cooled plants.

Can you provide a temporary chiller during a repair or replacement?

We coordinate rental chiller connections for critical facilities during major repairs or replacements so operations continue.

How often should a commercial chiller be serviced?

At minimum an annual comprehensive service plus quarterly operating checks. Critical process chillers often justify monthly visits.

Do you handle refrigerant compliance and reporting?

Our technicians are EPA certified and we document refrigerant use and leak repairs so you have records for California and federal requirements.

Chiller Service in Castro Valley, CA

Chillers serve the buildings and processes where downtime is most expensive: office towers, hospitals, data rooms, manufacturing lines, laboratories and food processing. We service air-cooled and water-cooled chillers, process chillers and the supporting pumps, cooling towers, valves and controls that make up a chilled water plant.

Chiller work demands documentation. We log operating conditions, refrigerant readings, approach temperatures and alarm histories so you can see trends and make replacement decisions based on data rather than a crisis.

Diagnostics

Common failures and what they mean

Fault 01

High approach temperature

Fouled tubes or coils reduce heat transfer and force the compressor to work harder. Cleaning restores capacity and efficiency.

Fault 02

Low chilled water flow alarms

Pump, strainer, valve or air-in-system problems. We check the hydronic side before blaming the chiller.

Fault 03

Chiller trips on high discharge pressure in the afternoon

Dirty condensers, failed condenser fans or recirculating hot air are the usual causes on air-cooled machines.

Fault 04

Refrigerant loss on an older machine

Aging seals, gaskets and tubes leak. We find and repair leaks rather than repeatedly topping off refrigerant, which is also a regulatory concern.
