Chiller Service & Repair in San Diego

Air-cooled and water-cooled chillers

Air-cooled chillers reject heat through their own condenser coils and fans. Water-cooled chillers send it to a cooling tower through condenser water pumps. We work on both, along with the chilled water side that feeds air handlers and fan coils.

What we check and repair

Common chiller calls include high head pressure or low suction alarms, compressor faults, refrigerant leaks, flow switch and sensor problems, tripped safeties and control issues. We read the controller's history, test the system and explain the repair and an honest, upfront quote before work begins. Office hours are Monday–Friday, 8 am–5 pm. After hours, our answering service takes your message and our office follows up the next business day.

Planned maintenance

Chiller maintenance typically includes logging operating pressures and temperatures, checking refrigerant charge and oil, inspecting electrical connections, cleaning air-cooled coils or checking condenser tubes on water-cooled units, and testing safeties and controls. We set up a schedule that fits your plant. See commercial preventive maintenance.

Older equipment

Many San Diego buildings still run older chillers, including McQuay units. When parts or efficiency stop making sense, we'll go over options and help you plan a replacement.
