What You'll Do as a Service Technician III

• Independently diagnosing, troubleshooting, repairing, and maintaining complex commercial HVAC systems (rooftop units, split systems, chillers, boilers, VAV boxes, air handlers, central plants, controls/DDC, and large-tonnage equipment).
• Performing advanced repairs including major component replacements (compressors, evaporators, condensers, controls, valves, pumps), refrigerant handling/recovery/recharge, system balancing, and startup/commissioning.
• Conducting thorough preventative maintenance, system performance testing, energy-efficiency assessments, and retrofits/upgrades as needed.
• Leading service calls from start to finish: assessing issues on-site, communicating clearly with customers about problems and solutions, coordinating parts/materials, and ensuring timely resolution.
• Ensuring all work complies with codes, regulations, manufacturer specifications, and Modigent safety/quality standards.
• Documenting service activities in detail (work orders, reports, as-builts, photos), maintaining accurate records, and providing recommendations for preventative programs or system improvements.
• Mentoring and guiding Service Technician I and II team members—demonstrating techniques, sharing best practices, and supporting their development on the job.
• Keeping tools, vehicles, and work areas organized, clean, and compliant with safety protocols.

What We're Looking For

• 5+ years of progressive hands-on experience in commercial HVAC service, repair, and maintenance.
• EPA Section 608 certification (Universal strongly preferred).
• Strong diagnostic and troubleshooting skills across wet-side (hydronic/chilled/hot water) and dry-side (air-side) commercial HVAC systems, including controls/DDC and advanced equipment.
• Proficiency with diagnostic tools, gauges, recovery machines, multimeters, and specialized HVAC test equipment.
• Prominent ability to work independently with minimal supervision while delivering high-quality, safe, and efficient results.
• Excellent customer-service, communication, and problem-solving skills; leadership mindset to mentor juniors and coordinate with teams.
• Strong commitment to safety, reliability, quality workmanship, and a positive attitude.
• Able to work in physically demanding conditions: lift up to 50 lbs, frequent bending/lifting, standing/walking on uneven terrain or in confined spaces, safely climbing ladders/scaffolding, and exposure to weather/elements.
• Valid driver's license and clean driving record required; additional certifications (NATE, specific manufacturer training, OSHA) a plus.
