Chiller Technician Jobs: Salary, Certifications & Career Outlook

Chiller technicians install, commission, and service centrifugal, screw, and absorption chiller systems in central plant HVAC applications, think high-rises, hospitals, universities, data centers, and large industrial facilities. It's one of the highest-paid specializations in commercial HVAC, demanding deep expertise in refrigerant systems, oil management, variable frequency drives (VFDs), and controls integration across major chiller platforms.

Top employers include OEM service networks (Carrier, Trane, York/Johnson Controls, Daikin/McQuay), national service firms, central plant operators, and facility management companies (CBRE, JLL, ABM, Aramark) at large commercial campuses. Experienced chiller techs are consistently among the most sought-after professionals in the mechanical trades.

Quick Facts

Role Type: Field service and maintenance, with some installation and commissioning
Salary Range: $70,000–$118,000/year
Hourly Range: $34–$57/hr (OEM service network rates typically exceed independent contractor rates)
Experience Required: 5–8 years commercial HVAC service with documented chiller experience; some roles require OEM factory training
Job Outlook: Very strong, driven by central plant growth in data centers and healthcare
Common Employers: Carrier Global, Trane Technologies, York (Johnson Controls), Daikin Applied (McQuay), CBRE, JLL, ABM Industries, Aramark Facilities, large hospital systems

Why Demand Is Strong

Data center construction is the biggest driver of chiller technician demand. Hyperscale and colocation facilities rely on large central plant chillers as their cooling backbone, and the construction boom in markets like Northern Virginia, Phoenix, Dallas, and Chicago is creating concentrated demand for technicians who can handle both startup and ongoing service.

The R-410A phasedown and the shift toward lower-GWP refrigerants (R-513A, R-1234ze, R-134a variants) are also fueling a wave of retraining and recertification across the industry. Meanwhile, hospital systems continue investing in central plant infrastructure; with 24/7 operations and zero tolerance for downtime, healthcare facilities place a premium on skilled techs who can deliver both planned maintenance and emergency repairs.

What Employers Look For

EPA 608 Universal certification (mandatory baseline)
OEM factory training: Carrier Certified Chiller Technician, Trane Chiller Service, or York factory certification significantly expand your authorized scope of work
NATE Commercial Refrigeration certification, valued by non-OEM employers
VFD startup and troubleshooting experience, since nearly all modern chiller compressors are VFD-driven
BAS integration and analytics skills: familiarity with EcoStruxure, Metasys, or SkySpark for trend log analysis and performance monitoring
OSHA 30, common for construction-phase commissioning work
Multi-platform experience: documented hours on centrifugal and screw chillers from multiple manufacturers puts candidates in the strongest position
