Lead Technician - Commercial HVAC

Location:

Southeast, FL (serving tri-county area)

About Us Air Force HVAC has been a trusted name in South Florida for over 5 years, delivering reliable residential HVAC service, installation, and maintenance across Broward, Miami-Dade, and Palm Beach counties. Our slogan, “Your Home, Our Mission,” guides everything we do.

We are on track to grow 8x year-over-year at the top line as we expand our technician team, client base, and service offerings. To achieve this ambitious growth, we are seeking a hands-on Field Service Manager to help us scale with excellence, develop leaders, and ensure operational discipline.

• Perform complex commercial HVAC service, diagnostics, repairs, commissioning support, preventive maintenance, and installation support.
• Serve as the escalation point for difficult technical calls and validate diagnoses through measurements, operating data, schematics, and sequence of operation.
• Mentor developing technicians, reinforce proper diagnostic methodology, and identify recurring training or performance gaps.
• Coordinate professionally with property managers, building engineers, facility teams, general contractors, and commercial clients.
• Maintain complete job documentation, equipment data, readings, photographs, parts requirements,
• recommendations, and job-status communication.
• Maintain company vehicle, tools, test instruments, and field resources in professional, job-ready condition.
• Commercial Systems Competency
• Strong field competency is expected across multiple commercial system categories, including:
• Packaged rooftop units (RTUs) and commercial split systems
• Water-source heat pumps (WSHP) and condenser-water-loop systems
• VRF/VRV systems and variable-capacity commercial equipment
• VAV systems, commercial air distribution, outside air, ventilation, and economizers
• Chilled-water fan coils, air handlers, hydronic heating/cooling systems, pumps, and control valves
• Cooling towers and associated condenser-water systems
• Commercial electrical systems, controls, VFDs, sensors, safeties, and BAS/DDC fundamentals

Candidates must demonstrate the ability to distinguish equipment-level failures from broader building-system conditions. Diagnosis should integrate refrigeration, electrical, airflow, controls, water flow, heat transfer, and manufacturer operating data rather than rely on assumption or unnecessary component replacement.

• Refrigeration: pressures, saturation temperatures, superheat, subcooling, temperature split, metering, compressor performance, and heat-transfer conditions.
• Electrical/Controls: high- and low-voltage circuits, transformers, relays, contractors, motors, safeties, sensors, transducers, VFDs, control boards, communication circuits, and wiring diagrams.
• Hydronic/Water-Side: entering/leaving water temperatures, water flow, strainers, valves, pumps, condenser-water loops, chilled-water systems, and cooling-tower interaction.
• Airflow: static pressure, blower performance, VAV operation, duct restrictions, ventilation, outside air, and air-balancing fundamentals.

• 10+ years of hands-on HVAC field experience with meaningful commercial service exposure.
• Demonstrated independent troubleshooting and diagnostic capability.
• EPA Section 608 certification and valid driver's license.
• Ability to read electrical schematics, technical literature, and sequence-of-operation documentation.
• Comfort with digital field-service platforms, mobile documentation, photographs, work orders, and electronic communication.
• Ability to work safely in rooftops, mechanical rooms, high-rise/commercial environments, and other field conditions.
• Bilingual communication skills strongly preferred;
  English/Spanish proficiency is highly desirable for South Florida commercial operations and customer coordination.
• Must possess and maintain the minimum professional hand tools and HVAC diagnostic instruments required to independently perform commercial service and troubleshooting; company-provided specialty equipment may be supplied as applicable.

• Manufacturer training is valued, but transferable commercial-system competency is more important than any single brand.
• VRF/VRV, WSHP, RTU, VAV, chilled-water, hydronic, cooling-tower, BAS/DDC, and VFD experience.
• High-rise, multifamily, hospitality, healthcare, institutional, or commercial retrofit experience.
• Track record of mentoring technicians or leading…
