Design‑Build, Retrofits, and Complex Phasing

Complex buildings are our specialty. We coordinate with owners, GCs, and facility teams to deliver VRV/VRF systems that fit budgets and timelines without compromising performance.

• Discovery and goals: site walk, existing system assessment, comfort/IAQ priorities
• Load calculations and zoning: room‑by‑room analysis, diversity, and piping routes
• Equipment selection: AC PRO–specified air handlers, accessories, and controls
• Coordination: BIM/3D clash checks, roof/structure reviews, seismic considerations
• Compliance: Title 24 documentation and local permit submittals
• Installation: nitrogen‑purged brazing, line set support, pressure testing
• Vacuum and charging: deep evacuation, accurate weighing, and verification
• Commissioning: controls setup, test & balance coordination, performance tuning
• Turnover: O&M documentation, user training, and warranty registration

Factory Training You Can Trust

Our engineers and technicians maintain factory training at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This specialized knowledge helps us engineer, install, commission, and service VRV/VRF systems correctly the first time, and support them for years with firmware updates, diagnostic tools, and approved procedures.

Service and Maintenance Plans

Reliable operation depends on proactive care. We offer tailored commercial maintenance plans for Fullerton facilities to protect uptime and efficiency.
