Commercial HVAC Chiller Technician (Centrifugal / Industrial)

Location: Corpus Christi, TX

Job Type: Full-Time | Year-Round Work

Work on Large-Scale Equipment, Not Residential Changeouts

H&G Systems has been a trusted name in mechanical contracting since 1968, delivering high-level service across commercial, institutional, and industrial facilities throughout Texas. From hospitals and data centers to manufacturing plants and large-scale facilities, our work is focused on complex systems where technical skill actually matters.

We are looking for an experienced Commercial HVAC Chiller Technician who specializes in centrifugal chillers and large tonnage equipment. If you enjoy troubleshooting complex systems, working independently in the field, and being the go-to expert on critical equipment, this is a strong long-term opportunity.

What You'll Do

In this role, you will diagnose, service, and maintain centrifugal chillers and related HVAC systems across commercial and industrial facilities. Your day will involve troubleshooting mechanical and electrical issues, performing preventative maintenance and overhauls, and supporting start-ups and commissioning of equipment. You will work with schematics, wiring diagrams, and control systems to identify issues and restore performance, while communicating directly with project managers, engineers, and customers on system status and recommendations. This is a field-based role where you'll manage your own service calls and take ownership of high-value, mission-critical equipment.

What We Offer

Pay: $45.00 - $55.00 per hour, depending on experience
Take-home vehicle (dispatched from home)
Uniforms provided
401(k) with 6% company match
Medical coverage (90% employee paid)
Dental and vision insurance
Paid time off (PTO)
8 paid holidays

Why Work With Us

Work on large commercial and industrial systems, not residential service
Consistent, year-round work with a stable company
High-level technical environment with complex equipment
Access to ABC training facility / CEF Construction Education Foundation
Tuition and book reimbursement for continued education
Ongoing leadership and technical development opportunities
Team culture built on respect, accountability, and craftsmanship

What We're Looking For

We're seeking a technician with at least 5+ years of experience working on centrifugal chillers or large commercial HVAC systems (York, Trane, Carrier, Daikin, or similar). You should have a strong understanding of refrigerant systems, controls, and compressor operation, along with solid electrical and mechanical troubleshooting skills. Experience with start-ups, commissioning, and performance testing is highly valued. EPA 608 Universal Certification and TDLR are required, and OEM factory training is a strong plus. You should be comfortable working independently, managing multiple service calls, and using basic digital tools for documentation. A valid driver's license and insurable driving record are required.
