Variable Refrigerant Flow VRF VRV technology delivers precise zoning, simultaneous heating and cooling with heat recovery, and exceptional part-load efficiency. That means lower utility costs, better comfort for tenants and staff, and system layouts that adapt to unique floor plans from historic properties near the Orange Plaza to modern offices and retail at The Outlets at Orange. In seismic Southern California, VRF VRV also reduces bulky ductwork, easing coordination and saving ceiling space.
With 80 plus years of engineering heritage, #1 AC Guys provides end-to-end delivery tailored to commercial needs:
• Detailed site survey and ACCA Manual N load calculations for accurate capacity and diversity selection.
• System architecture planning heat pump or heat recovery, indoor unit mix ducted, ductless, cassette, and refrigerant piping routes with branch selector boxes sized for future expansion.
• Title 24 compliance modeling and documentation, including acceptance testing coordination.
• City of Orange permit drawings, submittals, and plan check support, aligned with CBC, CalGreen, and local AQMD guidance.
• phasing strategies to keep businesses open during retrofit, weekend or after-hours cutovers, and clean jobsite practices to protect occupants.
• Factory start-up and functional performance testing to verify capacity, airflow, superheat, subcooling, and controls sequences.
Our engineers have trained at manufacturer facilities, including Fujitsu Japan, Mitsubishi Electric Thailand, Midea China, Gree China, and Haier China. This cross-platform knowledge helps us match the right equipment family and controls to your priorities energy, acoustics, footprint, or lifecycle cost, while preserving serviceability and parts availability in Orange County.
We integrate native VRF VRV controls with central plant or building automation via BACnet or Modbus where applicable. From smart thermostats to centralized supervisors with web dashboards, we set up trend logs, fault notifications, and scheduling that align with your operations. Zoning can be expanded later without major rework, and we design line sets and power distribution to make that growth seamless.
Healthy air equals healthy life. We pair VRF VRV with dedicated outdoor air systems DOAS, energy recovery ventilators, filtration up to MERV 13 where appropriate, and indoor air quality options such as demand-controlled ventilation, humidity management, and air quality monitoring. Our goal is to improve freshness and comfort while maintaining efficiency and code compliance.
From Title 24 and CalGreen documentation to City of Orange plan review, our team manages the paperwork and coordinates inspections. We address seismic bracing, refrigerant code considerations, and electrical requirements. Safety is baked into our process with job hazard analyses, lockout tagout procedures, and clean, organized work areas in occupied buildings.
• Office and coworking spaces seeking flexible zoning and low noise.
• Retail and mixed-use with varying occupancy and long piping runs.
• Hospitality and restaurants needing quiet guest comfort and kitchen-adjacent zones.
• Healthcare clinics and dental suites that benefit from improved ventilation strategies.
• Education, places of worship, and municipal facilities with diverse schedules and budgets.
Typical phases include discovery and concept 1 to 2 weeks, engineered design and permitting 2 to 6 weeks depending on scope, equipment procurement, installation and start-up with clear milestones, and commissioning with owner training and turnover packages O and M manuals, as-builts, warranty registration. Throughout, we provide line-item proposals, progress updates, and single-point project management for accountability.
Our specialty is complex, live-tenant retrofits and multi-zone heat recovery. We stage cutovers, utilize temporary conditioning when needed, and coordinate with other trades to protect finishes. For historic structures in Orange, we offer low-visibility indoor unit options and compact piping strategies that preserve aesthetics while meeting modern comfort expectations.
We model expected energy consumption and present lifecycle comparisons versus packaged RTUs or chilled water where relevant. Recommendations may include heat recovery VRF, demand response readiness, and utility-friendly controls sequences to help lower peak demand charges. Clear, line-item pricing keeps budgets predictable and avoids surprises.
