Chiller Technician Resume: How to Show Chiller Plants, Refrigerant, and Reliability in 2026

A chiller technician resume that only says "worked on chillers" gets filtered out. The employers hiring for this role care about one thing: can you service chillers, handle refrigerant, run the plant, and keep cooling reliable. The resumes that land interviews talk about chiller plants, refrigerant, and reliability — not just "worked on chillers."

What your chiller technician resume must prove

• Chiller service: centrifugal/screw/scroll, absorption, overhauls, tubes.
• Refrigerant: charging, recovery, leak checks, EPA 608, oil/analysis.
• Plant operation: cooling towers, pumps, condenser/chilled water, efficiency.
• Reliability: PM, controls/BAS, diagnostics, uptime, logs.

In one line: your resume should answer "what chillers did you service, how did you handle refrigerant, and how did you keep the plant reliable."

Don't just say "worked on chillers" — show refrigerant and reliability

"Worked on chillers" tells a plant manager nothing:

• ❌ "Worked on chillers." — Says nothing about refrigerant or reliability.
• ✅ "Serviced centrifugal and screw chillers, charged and recovered refrigerant to EPA 608, ran towers and pumps, and kept the plant up on PM." — Chiller service, refrigerant, plant, and reliability.

Quantify around: chillers/tonnage, refrigerant/leaks, plant/efficiency, uptime/PM. See how to quantify achievements on a resume. Keep numbers honest and handle refrigerant to regulation.

How to write the skills section

Group your chiller technician skills so a reviewer can scan them:

• Chiller service: centrifugal/screw/scroll, absorption, overhauls, tubes
• Refrigerant: charging, recovery, leak checks, EPA 608, oil/analysis
• Plant operation: cooling towers, pumps, condenser/chilled water, efficiency
• Reliability: PM, controls/BAS, diagnostics, uptime, logs
• Certifications: EPA 608 (universal), manufacturer chiller training, NATE

See how to write the skills section. For a chiller technician, lead with refrigerant and reliability — servicing is the means, an efficient, reliable cooling plant is the result. Related roles are the refrigeration technician resume guide and the boiler technician resume guide.

Chiller technician vs building engineer

These roles differ — keep your resume positioned:

• Chiller technician: specializes in chiller plants — chiller service, refrigerant, and plant operation.
• Building engineer: operates the whole building — see the building engineer resume guide — HVAC, electrical, and building systems broadly.

One specializes in chillers and cooling plant; the other operates all building systems. Tailor to the target role — see how to tailor your resume to a job description.

Common mistakes

• No refrigerant: charging, recovery, and EPA 608 are the headline.
• No plant: towers, pumps, and chilled/condenser water show plant depth.
• No reliability: PM, controls, and uptime show you keep cooling on.
• No chiller types: name the chillers (centrifugal/screw) you've serviced.
• Vague: "worked on chillers" loses to "serviced centrifugal chillers, charged to EPA 608, ran towers, kept plant up."

Frequently Asked Questions

What should a chiller technician resume highlight most?

Chiller service, refrigerant, plant operation, and reliability. Use chillers/tonnage, refrigerant/leaks, plant/efficiency, and uptime/PM to show your work — not just "worked on chillers." Handle refrigerant to regulation.

How do I quantify a chiller technician resume?

Use real numbers: chillers/tonnage, refrigerant/leaks, plant/efficiency, and uptime/PM. "Serviced centrifugal chillers, charged to EPA 608, ran towers, kept plant up" beats "worked on chillers." Keep numbers honest.

How is a chiller technician resume different from a building engineer resume?

A chiller technician specializes in chiller plants — chiller service and refrigerant. A building engineer operates all building systems broadly. One specializes in chillers; the other runs the building. Frame your resume to match the role.

Should a chiller technician resume list EPA 608?

Yes. EPA 608 (ideally Universal) is required to handle refrigerant; manufacturer chiller training and NATE add value — list them. Pair them with your chiller and plant record so employers see you keep cooling reliable and compliant.
