Modigent
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.

Perform advanced repairs such as major component replacements (compressors, evaporators, condensers, controls, valves, pumps), refrigerant recovery/recharge/handling, system balancing, startup/commissioning, and retrofits/upgrades. 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. Supervisory Responsibilities Yes – Provides coaching, mentoring, and technical guidance to junior Service Technicians (Levels I and II); may lead small service teams or coordinate with subcontractors on complex calls, ensuring alignment with safety, quality, and customer expectations. Requirements/Qualifications Experience : 5+ years of progressive hands‑on commercial HVAC service, repair, and maintenance experience; proven journeyman‑level proficiency in diagnosing and resolving advanced system issues independently. Education : High school diploma or GED required; trade school, apprenticeship completion, or equivalent preferred. Certifications : EPA Section 608 certification (Universal strongly preferred); NATE certification, manufacturer‑specific training, OSHA 10/30‑hour, or other relevant credentials a plus. Physical Demands : Ability to regularly lift and carry up to 50 lbs, climb ladders/scaffolding/stairs, work in confined spaces or at heights, bend/kneel/crouch, reach overhead, and use diagnostic tools/equipment for extended periods; frequent standing, walking, manual dexterity, and physical stamina required. 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. Proficiency with gauges, recovery machines, multimeters, combustion analyzers, and specialized HVAC test equipment. Excellent customer service, communication (verbal/written), problem‑solving, and mentoring skills. Safety leadership, documentation/reporting, multitasking, and independent decision‑making in high‑pressure situations. Benefits Competitive compensation based on experience and level, with opportunities for performance incentives and tool allowances where applicable. Comprehensive benefits including medical, dental, and vision coverage, plus HSA options with employer contributions in select plans, and company‑paid basic life and accidental death & dismemberment insurance. Paid time off, holiday pay, and a 401(k) retirement savings plan to support your long‑term financial well‑being. Professional development through hands‑on training, mentorship, apprenticeships, certifications, and clear career advancement paths across our nationwide operating companies. Inclusive, supportive culture that values diversity, dignity, respect, collaboration, integrity, and personal fulfillment—empowering you to build a rewarding, long‑term career.
