Core Responsibilities

Primary Functions

Assist lead HVAC technicians with the installation of split systems, packaged rooftop units, ductless mini-split systems, and commercial chillers by lifting, positioning, and securing equipment per installation plans and manufacturer specifications.
Prepare job sites by unloading materials, staging HVAC equipment, cutting and fitting copper refrigerant lines, and running electrical conduit and wiring under direct supervision.
Support brazing and soldering operations by purging lines with nitrogen, holding and securing tubing, and following safety protocols for torch use while under an experienced technician's guidance.
Perform basic refrigerant handling tasks such as assisting with refrigerant recovery, evacuation, and charging operations while complying with EPA 608 regulations and technician oversight.
Operate vacuum pumps, manifold gauges, digital manifold sets, and recovery machines to assist in evacuation, pressure testing, and system charging activities.
Conduct condenser and evaporator coil cleaning, fin straightening, and fan motor assistance to improve system efficiency and support preventive maintenance tasks.
Assist with ductwork installation and sealing, including hanging ducts, applying mastic or tape seals, insulating ducts, and supporting sheet-metal fitting to ensure proper airflow and low leakage.
Run condensate drain lines, clear blockages, install and test condensate pumps, and perform basic drain-line maintenance to prevent water damage and microbial growth.
Remove and replace filters, belts, capacitors, contactors, and other common field-service components under technician instruction, documenting parts used and serial numbers.
Support electrical tasks such as pulling wire, connecting low- and line-voltage circuits, replacing thermostats, and assisting with basic troubleshooting of electrical faults while following lockout/tagout and electrical safety rules.
Assist in start-ups and commissioning by helping measure system superheat/subcooling, airflow readings, static pressure tests, temperature splits, and recording startup parameters in service reports.
Perform pressure and leak tests using nitrogen and electronic leak detectors, help isolate leaks, and prepare components for repair or replacement following technician direction.
Load, unload, and transport HVAC equipment safely on and off trucks, use dollies and lifting equipment, and assist with rooftop unit placements using crane or lift coordination when required.
Maintain and organize service trucks, replenish commonly used parts and supplies, maintain accurate inventory counts, and request parts to minimize downtime on service calls.
Keep accurate field documentation: complete service tickets, collect customer signatures, note meter readings, and enter job details into mobile dispatch or CRM systems (e.g., ServiceTitan, FieldEdge) as requested.
Follow company safety procedures and wear required PPE (gloves, eye protection, respirator, fall protection) while assisting with confined-space entry, ladder work, and rooftop installations.
Assist with demolition and removal of old HVAC systems, handle refrigerant reclamation responsibly, and coordinate proper disposal or recycling of materials per environmental and company guidelines.
Support diagnostic troubleshooting by taking temperature, pressure, and electrical measurements, relaying observations to the technician, and suggesting simple corrective actions when trained to do so.
Communicate professionally with customers on-site to explain basic service steps, gather necessary access details, and ensure a positive experience while technicians complete repairs.
Participate in preventive maintenance rounds: replace filters, clean coils, lubricate moving parts, and document unit condition to extend equipment life and reduce emergency service calls.
Help with special projects including energy-efficiency upgrades, thermostat and controls upgrades, and sensor calibrations by preparing parts and assisting technicians during implementation.
Maintain clean, safe work sites by removing debris, sweeping work areas, and ensuring all tools and materials are returned to company vehicles at job completion.
Report equipment needs, unusual system behavior, and potential safety concerns to supervisors promptly to enable proactive maintenance and minimize service interruptions.

Secondary Functions

Assist with inventory tracking, restocking common service parts (filters, contactors, capacitors), and reporting low-stock items to the warehouse or dispatcher.
Support apprenticeship-style on-the-job training by shadowing experienced technicians and completing assigned training tasks, enhancing route readiness and technical capability.
Participate in safety briefings, toolbox talks, and continuing education sessions to stay current with EPA regulations, refrigerant updates, and company safety requirements.
Aid in site surveys and initial measurements for quoting and job preparation by measuring duct runs, noting access points, and documenting existing equipment.
Help prepare materials lists and job packets for installers and coordinate with suppliers for timely pickup or delivery of specialized components.
Provide backup support during peak seasons or emergency callouts to help triage service calls and reduce customer wait times.
Assist in basic diagnostic data entry and photo documentation for warranty claims and quality assurance reviews.
Support efforts to improve operational efficiency by suggesting minor process improvements from frontline experience and participating in post-job debriefs.
