• 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.

• 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.

• 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.

• EPA 608 Universal Certification (required)
• OSHA 10 (Cal/OSHA) required; OSHA 30 a plus
• California HVAC-related trade certification or documented journeyman-level experience
