Job description

Job Description:

The Purpose of Your Role as a Chiller Mechanic

The Chiller Mechanic will help keep critical cooling systems operating safely and reliably for our customers. This position focuses on maintaining, troubleshooting, and repairing commercial chillers and central plant equipment, helping facilities minimize downtime and operate at peak performance.

Your expertise will make a direct impact by solving complex mechanical issues, identifying problems before they become failures, and providing customers with trusted service they can rely on.

What You’ll Be Part Of

You’ll work on a variety of commercial and industrial facilities, supporting customers with both planned maintenance and complex repairs.

• Troubleshoot, maintain, and repair commercial chillers, central plant equipment, cooling towers, pumps, heat exchangers, and VFDs

• Service centrifugal, screw, and reciprocating chillers from manufacturers such as York, Trane, Carrier, Daikin, and Smardt

• Diagnose equipment issues, communicate findings with customers, and recommend practical repair solutions that improve system performance

• Work with EMS controls, BACnet integrations, and large tonnage chilled water systems to support reliable facility operation

• Maintain accurate service records, use proper diagnostic tools, and perform quality repairs that minimize repeat service calls

What We’re Looking for in You

• High School diploma required

• 10-15 years of relevant trade experience

• Experience troubleshooting, repairing, and maintaining commercial chillers and complex mechanical HVAC systems

• Strong understanding of centrifugal, screw, or reciprocating chillers, along with central plant equipment and controls

• Comfortable using Building Management Systems (BMS) and PC-based applications to diagnose and support equipment

• Working knowledge on how to retrofit advanced systems

What This Position Is (and Is Not)

This position is:

• Focused on servicing, troubleshooting, and maintaining complex mechanical systems

• A field-based role working directly with commercial and industrial customers

• An opportunity to apply advanced technical skills while mentoring less experienced technicians

This position is not:

• A general maintenance position

• Limited to preventative maintenance only

• Primarily office or administrative work

Why This Position Stands Out

This position offers the opportunity to work on some of the most complex cooling systems in commercial and industrial facilities. You’ll have the chance to solve challenging technical problems, work with a wide variety of equipment, and continue building your expertise alongside an experienced service team.

If This Sounds Like You

If you enjoy diagnosing complex equipment, take pride in quality workmanship, and want to be the technician customers trust when systems matter most, we’d like to connect.

Your life at Harris
