Commercial VRV/VRF Systems in Rialto, CA

Why VRV/VRF Is Ideal for Your Rialto Commercial Property

Modern variable refrigerant systems deliver exceptional part‑load efficiency, whisper‑quiet operation, and room‑by‑room control. Heat recovery configurations let you heat and cool different zones simultaneously, reclaiming energy that would otherwise be wasted. For offices, retail, education, hospitality, medical, and light industrial buildings, VRF/VRV minimizes mechanical room footprints and simplifies tenant improvements while maintaining superior comfort.

Engineer-Led Process From Concept to Commissioning

Our engineering DNA means every decision is backed by calculation and field experience. We start with a detailed site assessment, envelope review, and zoning strategy. Then we perform load calculations, select indoor/outdoor units, and plan piping, condensate, ventilation, and controls. We design around serviceability, acoustics, and lifecycle cost—not just first cost. During installation, our technicians follow manufacturer best practices, and commissioning includes leak/pressure testing, evacuation and charge verification, control logic validation, and occupant comfort tuning.

• Design-build or plan-and-spec execution
• Heat recovery and heat pump VRF configurations
• Ducted and ductless indoor unit options
• BACnet/Modbus BMS integration
• DOAS/ERV ventilation strategies
• Title 24 documentation and acceptance testing coordination

Healthy Air Is Our Mission

Healthy buildings start with clean, well‑ventilated air. We specify filtration strategies (MERV‑13+ where appropriate), demand‑controlled ventilation with CO2 sensing, and optional UV‑C or air purification enhancements. Proper outside air integration via DOAS and energy recovery can dramatically improve indoor air quality without sacrificing efficiency—ideal for schools, clinics, and high‑occupancy spaces.

Factory Training and Proven Sourcing

Our team is factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We pair that expertise with reliable sourcing through AC Pro to secure equipment, controls, and accessories on predictable timelines. The result: fewer delays, consistent specs, and systems that perform to design intent.

Retrofits, Expansions, and Complex Projects

Whether you are replacing aging rooftop units, converting from water‑cooled systems, or adding zones to support changing tenants, we excel at live‑site retrofits with minimal disruption. Our engineers map phasing, temporary conditioning, and tie‑ins to protect operations and schedules.

• Occupied‑building retrofit strategies
• Piping reroutes and refrigerant management
• Controls upgrades and networked thermostats
• Acoustic mitigation and vibration control

Controls and Building Integration

We integrate VRF/VRV with new or existing building management systems via BACnet or Modbus, enabling centralized scheduling, trending, and fault diagnostics. For multi‑tenant properties, we design metering and access strategies that keep operators in control while preserving occupant comfort.

Compliance and Documentation

California compliance is baked into our workflow: Title 24 performance, submittals, as‑builts, O&M manuals, and training for facility teams. We coordinate with inspectors and acceptance testers to move your project from plan to occupancy without surprises.

Service, Maintenance, and Optimization

After startup, we maintain your system to manufacturer standards, focusing on diagnostics, firmware updates, and proactive care. Seasonal optimization, refrigerant integrity checks, and coil cleaning protect capacity and efficiency—reducing energy spend and preventing downtime.

• Planned maintenance agreements tailored to usage
• Remote monitoring options and alarm response
• Lifecycle planning and upgrade roadmaps
