Core Responsibilities

Primary Functions

Perform complete installation of residential and commercial air conditioning systems including ducted split systems, ductless mini-splits, packaged rooftop units, and VRF/VRV systems according to manufacturer specifications and project blueprints, ensuring proper location, secure mounting, and compliant system orientation.
Read and interpret technical drawings, schematics, and architectural plans to determine correct equipment placement, duct runs, and control wiring paths; identify potential field conflicts and propose viable installation adjustments.
Install, size, and connect ductwork, plenums, registers, diffusers, and insulation; seal and test duct systems for leakage to meet performance and code requirements.
Handle refrigerant charging and recovery using industry-standard gauges and recovery machines; calculate correct refrigerant charge by superheat/subcooling or manufacturer method; comply with EPA 608 regulations and local refrigerant handling laws.
Evacuate and pressure-test refrigeration circuits using vacuum pumps and manifold gauges to detect and remedy leaks prior to charging, and perform brazing/soldering of copper lines while following brazing safety protocols.
Wire and connect electrical components, including disconnects, contactors, capacitors, transformers, motors, thermostats, and advanced control systems; troubleshoot electrical faults and verify correct voltage and amperage.
Commission new systems by performing start-up procedures, calibrating thermostats and controls, verifying airflow, static pressures, and temperature differentials, and documenting performance to ensure design specifications are met.
Diagnose and repair installation-related issues post-commissioning such as airflow imbalances, refrigerant leaks, control malfunctions, and mechanical noises; provide corrective action and re-test to validate repairs.
Install safety devices and system interlocks, including float switches, high/low pressure controls, overcurrent protection, and condensate management systems; enforce lockout/tagout procedures during maintenance and repair.
Provide detailed, professional customer interactions on-site: explain installation steps, operation, maintenance schedules, warranty terms, and energy-efficiency features; obtain customer sign-off and answer operational questions.
Coordinate with project managers, general contractors, electricians, plumbers, and sheet metal workers to sequence installation activities, mitigate schedule conflicts, and ensure efficient site workflow.
Maintain accurate job documentation including service tickets, installation checklists, start-up reports, material usage logs, and warranty paperwork in the company’s field software or paper records.
Perform preventive maintenance on installed systems — clean coils, replace filters, test capacitors and motors, inspect belts and bearings, and document findings to extend equipment life and reduce callbacks.
Adhere to all building codes, manufacturer installation standards, and occupational safety regulations (OSHA standards), including the use of appropriate PPE and safe handling of hazardous materials.
Operate and maintain hand and power tools, including vacuum pumps, brazing torches, refrigerant scales, multimeters, clamp meters, leak detectors, and combustion analyzers, and ensure tools are calibrated and safe to use.
Troubleshoot complex mechanical issues such as compressor failures, refrigerant migration, or refrigerant oil problems; liaise with suppliers or manufacturer technical support for warranty diagnostics when required.
Optimize system efficiency by recommending proper insulation, programmable thermostats, zoning, variable-speed equipment, and energy-efficient installation practices to improve performance and reduce operating costs.
Install, configure, and troubleshoot basic HVAC controls and thermostats including smart thermostats and Wi-Fi enabled controls; train customers on app-based control interfaces when applicable.
Ensure vehicles, tools, and material staging are organized and stocked for jobs; track inventory, report shortages, and requisition parts in a timely manner to meet installation schedules.
Respond to emergency service calls and perform after-hours diagnostics and temporary repairs when necessary to restore client comfort and safety.
Mentor and train junior technicians or apprentices on installation best practices, safety procedures, and manufacturer-specific start-up routines; review work for quality control and compliance.
Identify and document site-specific hazards, provide clear job hazard analyses (JHAs), and suggest mitigation measures to protect team members and property during installation activities.

Secondary Functions

Support pre-installation surveys and site assessments to create accurate material take-offs and labor estimates; provide feedback to project coordinators on site conditions that could impact schedules.
Assist sales teams with technical input for proposals, help generate scoped equipment lists, and support accurate quoting for replacement and retrofit projects.
Contribute to continuous improvement efforts by capturing field data on installation efficiencies, recurring failures, and recommended changes to standard operating procedures.
Participate in scheduled training sessions on new products, refrigerants, codes, and safety topics to maintain current technical competency and certifications.
Help maintain company compliance records including certification renewals, vehicle inspections, and tool calibration logs.
Provide constructive feedback during project debriefs to improve future installations and customer satisfaction metrics.
Occasionally perform light sheet-metal fabrication, custom duct modifications, and retrofit solutions when standard components cannot be applied.
Keep an organized digital or physical job folder for warranty claims, service histories, and commissioning documentation to support post-installation service teams.
