• Load calculations, equipment selection, refrigerant piping and branch boxes
• Ductless and ducted fan coils, DOAS integration, and ventilation upgrades
• Controls and BMS integration (BACnet/Modbus gateways, scheduling, zoning)
• Title 24 compliance support, submittals, and as‑builts
• Commissioning, start‑up, and performance verification to manufacturer standards
• Preventive maintenance programs and rapid diagnostics/repairs

• Office, retail, mixed‑use, and multifamily common areas
• Hospitality and food service
• Healthcare clinics and wellness facilities
• Education and civic buildings
• Light industrial, R&D, and warehouses (zoned comfort areas)

Design and Commissioning Details

Every project begins with a detailed site assessment, digital load modeling, and zoning strategy to match occupancy patterns. We optimize line lengths, elevation changes, and diversity factors to protect capacity and part‑load efficiency. Controls are mapped for intuitive operation and BMS interoperability. The result: stable temperatures, quieter spaces, and measurable energy savings.

Heat‑recovery configurations enable simultaneous heating and cooling across zones—ideal for mixed‑use and perimeter/core buildings. Where ventilation is needed, we pair DOAS with energy recovery for superior IAQ and humidity control.

Title 24, Documentation, and Turnover

• Complete Title 24 compliance support and acceptance testing coordination
• Submittal packages, shop drawings, and sequence of operations
• As‑built documentation and owner training
• Maintenance plans and performance benchmarks

Maintenance That Protects Your Investment

VRV/VRF systems reward proactive care. Our plans include coil cleaning, filter changes, electrical checks, firmware updates, control calibration, and refrigerant monitoring to catch issues early and preserve efficiency. We create site‑specific task lists and seasonal schedules to fit your operation with minimal downtime.

Healthy Indoor Air, Lower Energy

As engineers, we treat IAQ as a design requirement—not an afterthought. We specify ventilation strategies, filtration upgrades, and control sequences that stabilize CO₂ and humidity while keeping energy use in check. Cleaner air, quieter operation, better comfort—without sacrificing efficiency.

Service Area

We proudly serve Oxnard and all of Ventura County, and we also work across Los Angeles County and nearby areas including Orange County and Western Riverside County. If your portfolio spans multiple cities, we can standardize equipment and controls to simplify maintenance and training.

Our Process

• Assessment & goals: building walk‑through, data logging, and owner priorities
• Engineering & design: loads, zoning, equipment, and controls strategy
• Permits & submittals: Title 24, documentation, and coordination
• Installation: clean piping practices, pressure testing, evacuation, and charging
• Commissioning: verification, balancing, and owner training
• Lifecycle care: monitoring, seasonal tune‑ups, and continuous improvement
