Commercial Lennox VRF/VRV System Installation in Los Angeles

Our Commercial VRF/VRV Installation Process

Every building is unique. We tailor Lennox VRF/VRV solutions that align with your load profile, controls strategy, and lifecycle budget, then execute with engineering-level precision.

• Assessment & goals: Site survey, load and zoning review, IAQ targets, acoustics, and utility constraints.
• Design & modeling: Detailed load calculations, refrigerant routing, line sizing, and equipment placement for accessibility and serviceability.
• Equipment selection: Lennox VRF heat pump or heat recovery configurations for simultaneous heating/cooling and energy savings.
• Code & permits: Title 24 compliance, CALGreen, California Mechanical Code, ASHRAE 15 refrigerant safety, and LA jurisdictional requirements.
• Piping & power: Copper line sets, proper slope and oil return, isolation, seismic bracing, and clean power distribution.
• Leak prevention: Nitrogen pressure testing, triple evacuation, micron verification, and documented QC photos.
• Controls & BMS: BACnet integration, scheduling, setpoint strategies, and trend logs for performance verification.
• Commissioning: Manufacturer procedures, airflow balancing, sensor calibration, and acceptance testing.
• Training & turnover: O&M documentation, owner training, and a clear maintenance plan to protect your investment.

Engineered for Los Angeles Codes and Performance

Los Angeles projects demand more than a good install—they require code-smart engineering and airtight execution. We design Lennox VRF/VRV systems for compliance with Title 24 energy standards, ASHRAE 15 refrigerant concentration limits, and the California Mechanical Code, including ventilation and equipment access. Our team addresses seismic requirements, roof curb/structural coordination, and penetrations to maintain the building envelope. We also elevate indoor air quality with right-sized ventilation, MERV 13+ filtration, energy recovery options, and controls that balance comfort with efficiency.

From plan check to final inspection, we document calculations and commissioning to streamline approvals and protect your timeline.
