Air Cooled Chiller Maintenance Guide

A plain-English guide to chiller inspections, plant risk and service planning.

Why chillers need structured maintenance

Chillers combine electrical, mechanical and refrigerant systems, so a proper inspection needs to check all three, not just one.

What we check on site

Coil condition, compressor operation, refrigerant pressures, pump performance and control setpoints are reviewed during a chiller maintenance visit.

Planning around plant risk

Business-critical chiller plant benefits from a documented maintenance schedule that flags priority risks before they cause downtime.
