● Run and terminate refrigerant line sets; perform brazing, pressure testing, evacuation, and refrigerant charging in accordance with EPA 608 requirements.

● Install and wire low-voltage controls, thermostats, and basic electrical connections for HVAC equipment.

● Read and interpret residential and commercial mechanical plans, load calculations, and equipment schedules.

● Perform startup, commissioning, and system checkout, including airflow verification, refrigerant charge confirmation, and combustion analysis on gas equipment.

● Diagnose and troubleshoot system malfunctions on both new installs and existing equipment.

● Ensure all installations comply with California Mechanical Code, Title 24 energy requirements, local jurisdiction requirements, and (on applicable multi-family work) ASHRAE 62.2 ventilation standards.

● Coordinate with general contractors, property owners, facility managers, or homeowners to schedule work and minimize disruption.

● Maintain a clean, organized, and safe job site in compliance with Cal/OSHA standards.

● Accurately complete startup sheets, refrigerant tracking logs, material lists, and daily job documentation.

● Mentor apprentices/helpers assigned to the job as needed.

● Coordinate and prepare for local building department and utility inspections.

Qualifications:

● Minimum 4+ years of hands-on HVAC installation experience across residential and commercial systems.

● Strong working knowledge of refrigeration cycle, electrical/controls, and airside/ductwork systems.

● Ability to read and work from mechanical plans, load calculations, and equipment submittals.

● Experience with both gas furnace/split-system and heat pump equipment; light-commercial packaged/rooftop unit experience a plus.

● Valid driver's license and reliable transportation; ability to travel between job sites daily.

● Ability to pass a background check and drug screening (required on HUD/Section 8 and many commercial sites).

● Bilingual (English/Spanish) a plus.

Required Certifications:

● EPA 608 Universal Certification (required)

● OSHA 10 (Cal/OSHA) required; OSHA 30 a plus

● California HVAC-related trade certification or documented journeyman-level experience
