Position Overview

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.

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.

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
