Remote jobs

Chiller technicians specialize in the installation, startup, commissioning, and service of centrifugal, screw, and absorption chiller systems used in central plant HVAC applications: high-rise buildings, hospitals, universities, data centers, and large industrial facilities. This is one of the most technical and highest-paid specializations in the commercial HVAC service field, requiring deep knowledge of refrigerant systems, oil management, variable frequency drives, controls integration, and the specific operational characteristics of each chiller platform. Employers include national service firms, OEM service networks (Carrier, Trane, York/Johnson Controls, Daikin/McQuay), central plant operators, and facility management companies at large commercial campuses. Experienced chiller techs are among the most sought-after technicians in the mechanical trades.

Quick Facts

Role Type: Field technical, service and maintenance focus; some installation and commissioning Typical 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; central plant infrastructure growth in data centers and healthcare is driving sustained demand Common Employers: Carrier Global, Trane Technologies, York (Johnson Controls), Daikin Applied (McQuay), CBRE, Jones Lang LaSalle, ABM Industries, Aramark Facilities, large hospital systems

Why Demand Is Strong

Data center construction is the primary growth driver for chiller technician demand right now. Hyperscale and colocation data center facilities use large central plant chiller systems as the backbone of their cooling infrastructure, and the pace of new data center construction in markets like Northern Virginia, Phoenix, Dallas, and Chicago is creating concentrated demand for chiller techs who can support both startup and ongoing service. At the same time, the R-410A phasedown and the upcoming transition of many commercial chiller platforms to lower-GWP refrigerants (R-513A, R-1234ze, R-134a variants) is creating a retraining and recertification wave. Healthcare systems continue to invest in central plant infrastructure, and hospital mechanical plants run 24/7 with zero tolerance for downtime, which puts a premium on skilled chiller technicians who can perform planned maintenance and emergency repairs with equal competence.

What Employers Are Looking For

EPA 608 Universal certification is the mandatory starting point. OEM factory training is a major differentiator: Carrier Certified Chiller Technician, Trane Chiller Service training, or York factory certification credentials are actively preferred by OEM service networks and will significantly expand the scope of work you are authorized to perform. NATE certification in the Commercial Refrigeration specialty is valued by non-OEM employers. Experience with VFD startup and troubleshooting is expected because virtually all modern chiller compressors are VFD-driven. Familiarity with chiller BAS integration, trend log analysis, and performance monitoring platforms (EcoStruxure, Metasys, SkySpark) is increasingly required as data-driven maintenance programs become standard at large facilities. OSHA 30 is common on construction-phase commissioning work. Candidates who have logged documented hours on centrifugal and screw chiller platforms from multiple manufacturers are in the strongest position.
