Commercial Exhaust Fan Services in Los Angeles — Daikin-Focused Expertise

What We Do

We engineer and deliver code‑compliant commercial exhaust solutions that integrate smoothly with your Daikin systems. Our scope covers design‑build projects, replacements, and advanced retrofits while minimizing downtime for your business.

• Design, specification, and sizing of rooftop, inline, and wall‑mount exhaust fans
• Installation and replacement with curb adapters, roof penetrations, and proper flashing
• Controls integration (VFDs, EC motors, demand‑controlled ventilation, CO/NO2 sensors)
• Commissioning and Test & Balance (TAB) for verified airflow and pressure
• Kitchen exhaust and hoods aligned to NFPA 96 with grease duct best practices
• Parking garage exhaust with sensor‑based modulation for energy savings
• Laboratory and process exhaust with dilution and corrosion‑resistant components
• Planned maintenance, vibration analysis, and reliability upgrades

Daikin‑Focused Integration

We routinely design and implement exhaust strategies around Daikin commercial systems. That includes coordination with Daikin VRV/VRF, ventilation equipment, and building automation for stable building pressure and efficient energy use. We follow manufacturer documentation and industry standards to maintain performance and warranty integrity.

• Fan selection matched to Daikin ventilation loads and space usage
• Airflow balancing to protect comfort cooling and make‑up air performance
• Controls alignment via BACnet/Modbus gateways where applicable
• Sequencing to prevent negative pressure, odors, and door pull
• Integration of heat/energy recovery where design allows

Applications We Serve

• Commercial kitchens, food service, and hospitality
• High‑rise, mixed‑use, and retail buildings
• Laboratories, light manufacturing, and R&D spaces
• Parking garages and smoke purge systems
• Healthcare offices and wellness facilities

Engineering, Codes, and Documentation

Every project is engineered for safety and compliance. We provide sealed drawings when required, permit‑ready submittals, and closeout documents your facilities team can rely on.

• California Title 24 and local energy code compliance
• NFPA 96 for commercial cooking operations
• UL 705 fan listings and SMACNA duct standards
• Seismic anchorage and roof support details per local code
• Noise and vibration control with isolation bases and flexible connectors

Our Process

• Assessment: Site survey, airflow and pressure diagnostics, and fan curve checks
• Design: Load calculations, equipment schedules, controls sequences, and submittals
• Install: Safe rigging, curb adapters, electrical, controls, and start‑up
• Commission: TAB, controls tuning, documentation, and staff orientation
• Maintain: Preventive service plans to protect uptime and efficiency

Common Issues We Fix

• Insufficient CFM or poor capture in kitchens and process areas
• Excessive noise, vibration, and premature bearing or belt failures
