Core Responsibilities

Primary Functions

Install, set up and commission residential and commercial air conditioning systems (split systems, packaged rooftop units, chillers, VRF/mini‑split systems) following manufacturer specifications, local codes and best practices to ensure reliable performance and warranty compliance.
Diagnose mechanical, electrical and refrigerant-related faults using multimeters, clamp meters, manifold gauges, vacuum pumps, leak detectors and electronic analyzers; develop corrective action plans and complete repairs efficiently.
Perform scheduled preventive maintenance including filter replacement, coil cleaning, condenser and evaporator inspections, fan and motor lubrication, belt tensioning, and condenser drain clearing to maximize system longevity and efficiency.
Recover, reclaim and recharge refrigerants in strict compliance with EPA 608 regulations and company environmental policies; maintain accurate refrigerant logs and documentation for regulatory inspections.
Read, interpret and work from electrical schematics, control diagrams, blueprints and installation manuals to wire, plumb and mount equipment correctly; verify electrical connections, phase orientation and control logic.
Replace and repair components such as compressors, reversing valves, expansion valves, contactors, capacitors, relays, thermostats, sensors, blower motors and control boards while ensuring proper calibration and performance testing.
Perform pressure testing, evacuation and vacuum procedures, leak detection and system charging during start‑up; validate system performance through temperature split, superheat/subcooling and amperage measurements.
Troubleshoot HVAC control systems, thermostats, zone dampers, BACnet/Modbus interfaces and building automation systems; program and calibrate controls to achieve sequence-of-operations and energy targets.
Conduct heat load calculations (Manual J) and duct design/load distribution (Manual D) or use approved software tools to recommend properly sized systems and energy-efficient solutions for new installs and retrofits.
Provide professional, clear estimates and scope-of-work recommendations to customers and stakeholders, explaining repair options, expected outcomes, timelines, parts costs, warranties and energy-saving benefits.
Maintain accurate and timely service records, job tickets and asset documentation using mobile field service management software; upload photos, test data and sign-offs to ensure traceability and compliance.
Adhere to OSHA, NFPA and company safety standards on every job site: use PPE, follow lockout/tagout procedures, manage fall protection, and conduct job safety analyses before fieldwork begins.
Mentor and coach junior technicians and apprentices by demonstrating best practices, reviewing completed work for quality, and providing hands-on training in troubleshooting and safety.
Coordinate with project managers, electricians, plumbers and other trade partners to sequence work, resolve site issues and meet project milestones while maintaining a clean and professional job site.
Inspect and repair condensate drain systems, pumps and pan heaters to prevent water intrusion and mold risk; implement corrective actions for recurring drainage problems.
Perform ductwork repairs, modifications and sealing; install and insulate duct runs, test for airflow balance and perform zoning adjustments to meet comfort and efficiency targets.
Recommend and implement energy conservation measures such as variable frequency drives (VFD) installation, thermostat upgrades, system retrofits and maintenance plans that lower operating costs and improve system performance.
Manage parts inventory and tools: order parts, track warranties and returns, maintain stock levels on service vans to minimize downtime and repeat trips.
Respond to emergency service calls and participate in rotational on-call schedules; diagnose urgent failures and perform temporary or permanent repairs to restore critical HVAC function.
Ensure compliance with local building and refrigerant regulations, secure necessary permits and coordinate with inspectors during new installations and major repairs.
Execute commissioning checklists and prepare detailed start-up and performance reports; create punch lists and follow through to project acceptance.
Dispose of hazardous waste and used refrigerants in accordance with environmental and company policies; maintain manifests and disposal documentation.
Use digital diagnostic tools and mobile apps to capture system performance data, trend historical information and support remote troubleshooting where applicable.

Secondary Functions

Participate in continuous improvement initiatives: suggest process improvements, tool upgrades and workflow optimizations to improve first‑time fix rate and customer satisfaction.
Support sales and estimating teams with technical input on complex proposals, scope clarification and materials take-offs.
Assist with fleet and equipment maintenance: inspect ladders, tools and van inventory to ensure readiness and safety.
Attend training sessions and keep certifications current (e.g., EPA 608, manufacturer-specific training, safety courses) to maintain technical competency.
Represent the company professionally at client sites, resolving disputes diplomatically and maintaining high customer satisfaction scores.
