Commercial Exhaust Fan & Ventilation Wiring in Santa Monica

Fan sizing depends on your space volume, occupancy, and ventilation requirements. A cafe near the Pier with open kitchen might need 500-1000 CFM per minute per hood, while a creative office by Bergamot needs 0.15-0.20 CFM per square foot. HVAC code and fire code set minimums, which vary by use. We conduct a site survey, coordinate with your mechanical contractor, and size the right fan to meet code without over-specifying (which wastes energy). Undersizing causes cooking odors and humidity; oversizing runs up your energy bill.

Yes. We install BACnet or Modbus-ready controllers so your fans integrate with building management systems. Demand-controlled ventilation using CO2 or humidity sensors automatically adjusts fan speed, cutting energy use 20-40%. You can monitor runtime, filter status, and alarms from your phone or computer. For multi-tenant buildings on Wilshire or downtown, this level of control lets you bill tenants fairly and respond quickly to equipment issues without waiting for on-site visits.

VFDs ramp fan speed up or down based on real demand rather than running at full power constantly. A hotel on Wilshire with varying occupancy can reduce fan energy by 40-60% using VFDs combined with demand sensing. When occupancy or odor/humidity drops, the VFD slows the fan proportionally, cutting noise and electricity use. Payback is typically 2-4 years through lower utility bills, and many properties qualify for SCE rebates that offset 20-30% of VFD installation costs.

Any new fan wiring requires electrical permits and City of Santa Monica Building and Safety approval. Kitchen hood installations may also need fire marshal review per NFPA 96 kitchen ventilation standards. We prepare all submittals (one-line diagrams, load calcs, as-built plans), coordinate with the mechanical contractor's submittals, and attend inspections. Permitting typically takes 1-2 weeks. Our experience with Santa Monica Building and Safety means fewer plan-check comments and faster approval.

Salty fog corrodes standard conduit and hardware, shortening system life. Rooftop exhaust fans are especially exposed to salt air near the beachfront. We specify stainless steel or hot-dipped galvanized hardware, LFMC/LFNC-B liquidtight flexible conduit for rooftop connections, and NEMA 4X or epoxy-coated enclosures. Vibration-isolation connectors also minimize noise transmission while protecting connections from moisture. These upgrades add 10-15% to material cost but extend system life by 5-10 years in our coastal environment.

Most Santa Monica installations take 4-8 hours (often a half day), depending on complexity and distance from the panel. For cafes and restaurants, we coordinate timing to minimize kitchen disruption, usually installing during off-hours or between service periods. Pre-planning, coordination with your mechanical contractor, and staged panel work help us stay on schedule. Once installed, function testing and commissioning take 1-2 hours, after which your fans are ready to go.
