Work Environment/Safety : Primarily field-based in commercial/industrial settings (indoor/outdoor, rooftops, mechanical rooms, varying weather); exposure to noise, dust, heights, refrigerants, electrical hazards, and extreme temperatures; must strictly adhere to OSHA regulations, EPA protocols, conduct hazard identification, and wear required personal protective equipment (PPE) such as hard hats, safety glasses, gloves, harnesses, and steel-toed boots at all times—safety is our top priority and non-negotiable. As a Service Retrofit Start Up Technician I, you'll begin your career in commercial HVAC retrofit and system startup by assisting experienced technicians with basic installations, repairs, and commissioning of equipment in office buildings, hospitals, schools, retail spaces, and industrial facilities.
