Commercial VRF/VRV System Installation in Los Angeles

Why VRF/VRV Is the Smart Choice for Commercial Buildings

Variable Refrigerant Flow (VRF) and Variable Refrigerant Volume (VRV) systems deliver precise zoning, excellent energy savings at part load, flexible piping layouts, and low acoustic impact—perfect for modern offices, medical suites, hospitality, retail, education, and multifamily common areas. With heat recovery options, you can heat and cool different zones simultaneously, reclaiming energy and improving comfort throughout the building.

Our Design–Build Approach

As a fourth‑generation, family‑owned contractor with 80+ years of engineering expertise, #1 AC Guys manages the entire lifecycle of your project. We start with a detailed site survey and load analysis, then produce a code‑compliant design that meets Title 24 and local AHJ requirements. We coordinate drawings, seismic supports, refrigerant piping design, ventilation/DOAS integration, and controls strategy to ensure performance, safety, and maintainability.

We provide stamped calculations where required, submit for permits, and maintain clear communication with building ownership, facility managers, and GCs. After installation, our factory‑trained commissioning team validates charge, superheat/subcooling, addressing, controls, and safety interlocks so your system runs exactly as designed.

Factory‑Trained on Leading VRF Platforms

Our engineers have trained with top global manufacturers at the factory level, including Mitsubishi Electric, Fujitsu, Midea, Gree, and Haier. That background means better equipment selection, cleaner refrigerant routing, correct branch box placement, accurate control addressing, and dependable startup and commissioning. We specify and install matching accessories, branch controllers, indoor unit types, and DOAS pairings to maximize efficiency and indoor air quality.

What We Deliver

• Concept and feasibility studies for new and retrofit projects
• Load calculations, energy modeling, and Title 24 documentation
• Complete design drawings and submittals
• Permitting and inspections coordination
• Professional installation: refrigerant piping, brazing, nitrogen purge, evacuation, and leak testing
• Controls integration with BMS/BACnet and advanced scheduling
• Commissioning, owner training, and turnover documentation
• Post‑install maintenance plans and warranty support

Healthy Air, Healthy Teams

Our mission is Healthy Air at Work. We engineer systems that pair VRF/VRV with proper ventilation (DOAS), high‑efficiency filtration, and smart controls to promote cleaner indoor air, stable temperatures, and better productivity. From boardrooms to patient areas to creative studios, we tune zone controls for the right humidity and comfort profile.

Complex Projects Are Our Specialty

High‑rise tenant improvements, mixed‑use developments, historic retrofits, and multi‑tenant office floors all demand careful phasing and coordination. We excel in tight timelines and occupied spaces, sequencing work to minimize disruption. Our team documents refrigerant volume compliance, addresses line length limitations, and applies best practices for oil return, branch selection, and condensate management—so your installation is as robust as it is efficient.

Compliance, Rebates, and Savings

We deliver Title 24 compliance, CALGreen alignment, and local permitting support across Los Angeles County and neighboring Orange County, Ventura County, and Western Riverside County. Our estimators help identify potential incentives and utility programs (such as LADWP, SCE, and regional energy initiatives) and prepare the documentation you need to capture available rebates for high‑efficiency equipment.

Controls and Building Integration

Whether you need simple central controllers or full BMS integration, we configure open protocols (like BACnet) and user‑friendly dashboards for facility teams. Expect zone‑level scheduling, setpoint management, trend logs, email alerts, and remote access—giving you transparent performance and lower operating costs.

Lifecycle Support

After commissioning, we offer tailored maintenance plans that preserve efficiency, protect warranties, and extend equipment life. Routine inspections, coil cleaning, firmware updates, and performance checks keep your VRF/VRV system running at its best—season after season.

Service Area

We proudly serve Los Angeles County and surrounding Orange County, Ventura County, and Western Riverside County. From downtown towers to coastal campuses and industrial parks, our teams mobilize quickly and arrive prepared.
