What You'll Do as a Service Technician IV:

This senior/lead-level role is for master technicians who combine deep technical expertise with strong leadership. You'll handle the most demanding commercial HVAC service work, oversee junior techs on-site, provide expert guidance to customers, and contribute to operational excellence. Key responsibilities include:

• Leading complex service projects and high-priority calls: advanced diagnostics, major repairs, system overhauls, retrofits, and optimization of sophisticated HVAC plants (chillers, boilers, central plants, VRF/VRV, large-tonnage rooftop systems, air handlers, controls/DDC/BMS integration).

• Overseeing and directing junior technicians (Levels I-III) on-site: delegating tasks, demonstrating advanced techniques, ensuring quality/safety compliance, and providing real-time mentorship and training.
• Serving as the primary technical point of contact for customers on critical accounts—explaining issues/solutions clearly, recommending preventative programs, system upgrades, or capital improvements, and building long-term trust.
• Coordinating with dispatch, field leadership, parts/warehouse, and other trades to resolve escalated or multi-system issues efficiently.
• Conducting thorough post-service reviews, documenting detailed reports (work orders, as-builts, photos, recommendations), and contributing to continuous improvement initiatives (process enhancements, safety protocols, training content).
• Upholding and enforcing Modigent safety, quality, and documentation standards on every job, including high-risk or mission-critical environments.

What We're Looking For:

• 7-10+ years of progressive commercial HVAC service, repair, and maintenance experience, with proven mastery across diverse equipment and systems.
• EPA Section 608 Universal certification required; additional credentials strongly preferred (NATE Advanced, specific manufacturer certifications, journeyman license, controls training, OSHA 30, etc.).
• Advanced diagnostic and leadership skills: expert troubleshooting of wet-side (hydronic/chilled/hot water) and dry-side (air-side) systems, controls/DDC/BMS, VFDs, and integrated building systems.
• Demonstrated ability to lead teams, mentor effectively, make sound decisions under pressure, and deliver consistent high-quality results with minimal supervision.
• Exceptional customer-service, communication (verbal/written), and problem-solving abilities; professional demeanor when interacting with facility managers, engineers, and executives.
• Strong commitment to safety, reliability, quality workmanship, and a positive leadership attitude.
• Ability 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.
