Centrifugal Chiller Field Service Specialist

Centrifugal Chiller Field Service SpecialistH and G Systems — Dallas–Fort Worth, TX $45–$55 per hour + Take-Home Vehicle | Full-Time, Year-RoundA day in the life

You start your morning in your driveway, not a shop. From your take-home vehicle, you review your first dispatch and head straight to a hospital, data center, or manufacturing facility. Your focus: keep mission-critical centrifugal chillers running at peak performance. You diagnose, repair, and optimize large-tonnage HVACR systems—mechanical, electrical, refrigeration, and controls—then document everything through digital reporting before moving to the next site.

Afternoon might bring a start-up or commissioning of a newly installed unit, coordinating with facility teams to verify setpoints and performance. By day’s end, you’ve prevented downtime in environments that can’t afford it—and you never once took a residential call.

About H and G Systems We are a Dallas–Fort Worth mechanical contractor with 55+ years of success in high-performance commercial and industrial refrigeration. Our service team supports organizations that rely on reliability—think healthcare, data infrastructure, and advanced manufacturing.
