Service Technician III

As a Service Technician III, you'll operate as a senior/journeyman-level expert, independently handling complex commercial HVAC service calls, advanced diagnostics, repairs, maintenance, and system startups across a wide range of equipment in buildings, hospitals, schools, industrial facilities, and more. Lead service efforts on challenging jobs, mentor junior technicians, and deliver high-reliability solutions that ensure code compliance, energy efficiency, and outstanding customer satisfaction. Our people-first culture empowers your mastery with specialized training, certifications, leadership opportunities, and the fulfillment of keeping critical commercial systems running safely and sustainably nationwide.

Conduct thorough preventive maintenance, performance testing, energy-efficiency assessments, leak detection, and system optimization to minimize downtime and extend equipment life.
Lead full service calls from dispatch to completion: assess on-site issues, communicate clearly with customers on findings/recommendations/solutions, coordinate parts and materials, execute work, and follow up for satisfaction.
Ensure all work complies with codes, regulations, manufacturer specifications, EPA requirements, and Modigent safety/quality standards.
Document service activities in detail (work orders, reports, photos, as-builts, recommendations) and maintain accurate records for billing, warranty, and continuous improvement.
Mentor and guide Service Technician I and II team members by demonstrating techniques, sharing best practices, supporting on-the-job learning, and promoting safety and quality standards.

Work Environment/Safety: Primarily field-based in commercial/industrial settings (indoor/outdoor, varying weather, rooftops, mechanical rooms); 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. This is a safety-sensitive position. Frequent regional travel within assigned market, on-call rotations, and flexible hours (including evenings/weekends) may be required as business needs dictate.

Required Skills

Advanced diagnostic/troubleshooting across commercial HVAC equipment (RTUs, chillers, boilers, controls/DDC, hydronic/air systems).
Refrigerant handling/recovery/recharge (EPA-compliant), component replacement, system balancing, startup/commissioning.
