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…
