Commercial VRF/VRV System Installation in Fontana

What Is VRF/VRV — And Why It Fits Fontana Facilities

Variable Refrigerant Flow (VRF), also known as VRV, is a high‑efficiency heat pump platform that precisely matches capacity to demand across many zones. For Fontana’s diverse commercial properties — logistics, manufacturing support, retail, offices, schools, and clinics — VRF/VRV offers flexible piping, compact indoor units, low noise, and advanced zoning that minimizes energy waste and downtime.

• Energy savings via variable speed compression and zoning
• Heat recovery models provide simultaneous heating and cooling
• Tight architectural integration with small refrigerant piping
• Quiet operation and excellent part‑load efficiency
• Robust controls with BMS integration (BACnet/Modbus)

End‑to‑End Engineering, Built for Complexity

We excel at large and technically demanding projects. Our licensed team handles design‑build or plan‑and‑spec execution with meticulous attention to airflow, refrigerant routing, and controls architecture. Every project begins with a data‑driven assessment and ends with verified performance.

• Site survey, load calculations, and zone planning
• System selection and options analysis (heat recovery vs. heat pump)
• Civil/structural coordination for roof loads and seismic bracing
• Title 24 documentation and permitting coordination
• CAD/BIM coordination for piping, condensate, and electrical
• Equipment staging, crane plans, and safety management
• Factory‑level commissioning and owner training

AC PRO Sourcing for Speed and Reliability

Downtime costs money. We streamline lead times by sourcing VRF/VRV equipment, controls, and accessories through the AC PRO distribution network. That means faster availability, dependable parts support, and fewer schedule surprises — especially important on fast‑track TI and retrofit projects.

Factory‑Trained Craftsmanship

Our engineers and installers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This training informs our pipework standards, flare/braze quality, evacuation and dehydration procedures, leak testing, and controls commissioning — the details that make your system efficient, quiet, and long‑lasting.

Controls, BMS, and Commissioning

From standalone VRF controllers to enterprise BMS, we deliver clean, interoperable controls. Our team integrates BACnet or Modbus gateways, sets up schedules and setbacks, configures ventilation lockouts, and verifies sensor accuracy. Commissioning includes nitrogen pressure tests, vacuum targets, refrigerant charge validation, and functional performance testing to document capacity, airflow, and comfort.

• BACnet/Modbus integration and point mapping
• Networked thermostats and centralized controllers
• Trend logs that quantify savings
• Operator training and documentation handoff

Healthier Indoor Air by Design

Healthy air is our mission. We combine VRF/VRV with right‑sized ventilation and filtration strategies for long‑term IAQ. Options include dedicated outdoor air systems (DOAS), energy recovery ventilators (ERV), demand‑controlled ventilation with CO₂ sensors, and MERV‑rated filtration tailored to your occupancy and processes.

• Balanced ventilation with heat/energy recovery
• MERV filtration targeting your risk profile
• Humidification/dehumidification strategies where needed
• Cleanable, serviceable designs to maintain performance
