Our state-of-the-art facilities in Santa Ana prioritize precision climate control, biological safety, and crop excellence—creating the perfect environment for our plants to thrive. We're committed to fostering a team of skilled professionals who share our passion for innovation, quality, and compliance. Join us to play a critical role in shaping the future of responsible cannabis cultivation! Job Overview We're seeking a detail-oriented HVAC Journeyman Technician to maintain, repair, and optimize the climate control systems that are vital to our indoor cultivation operations. As part of our facility team, you'll ensure temperature, humidity, air quality, and ventilation levels stay within strict parameters to support healthy plant growth, minimize downtime, and comply with California cannabis regulations. This role is ideal for HVAC professionals looking to specialize in a high-growth industry where their work directly impacts product quality and yield. Key Responsibilities Perform routine preventative maintenance on HVAC systems (air handling units, dehumidifiers, refrigeration, ductwork, and VFDs) to prevent unexpected failures in our 24/7 cultivation facilities. Troubleshoot and repair malfunctions (e.g., refrigerant leaks, sensor calibration issues, fan motor failures) that could disrupt optimal growing conditions (target: 65-75°F, 40-60% humidity, 1200-1500 ppm CO₂). Install new HVAC equipment or upgrade existing systems to improve energy efficiency, air filtration (HEPA/UV-C), and climate precision for vegetative and flowering stages. Collaborate with facility managers and crop specialists to adjust HVAC settings in response to plant health needs (e.g., reducing humidity during mold risk periods or increasing CO₂ for faster growth). Monitor and document system performance, maintenance logs, and compliance with Cal/OSHA, California Bureau of Cannabis Control (BCC), and CDFA regulations. Ensure all work adheres to safety protocols (e.g., lockout/tagout, proper handling of refrigerants, PPE use) to protect team members and crop assets. Assist with facility expansions or retrofits to support scaling cultivation operations.
