Calabasas Commercial Exhaust Fans

Purpose‑Built Exhaust for Calabasas Facilities

Whether you operate a restaurant on Calabasas Road, a boutique studio at The Commons, or a corporate office along the 101, #1 AC Guys delivers commercial exhaust fan systems that remove heat, smoke, odors, moisture, and contaminants at the source. We service and install rooftop upblast fans, inline centrifugal fans, mixed‑flow fans, cabinet exhaust, garage CO/NO₂ systems, restroom exhaust, warehouse and production extraction, and NFPA 96 kitchen hood exhaust with UL 762 grease fans — all sized and tuned to your space, process loads, and occupancy patterns.

Engineering‑Led Design, Installation, and Replacement

Our fourth‑generation team brings 80+ years of applied engineering to every project. We calculate CFM and static pressure, evaluate duct layout and termination, apply AMCA performance data, and select motors and wheels for efficiency and longevity. Expect right‑sized equipment, proper curb and roof penetration detailing, sealed ductwork, vibration isolation, flexible connectors, and field balancing that delivers the airflow we promise. For replacements, we assess existing power, curb dimensions, and controls to avoid costly rework and downtime.

Code Compliance and Permits — No Guesswork

We handle permitting and plan submittals for Los Angeles County and the City of Calabasas, aligning with California Mechanical Code, Title 24, local AQMD requirements, OSHA, and NFPA 96 for commercial kitchens. From make‑up air coordination and interlocks to grease duct clearances and roof service clearances, your system is built to pass inspection the first time — and to keep your team and guests safe every day.

Energy Efficiency, Controls, and BAS Integration

Reduce operating costs with EC motors, premium‑efficiency motors, and VFDs matched to demand. We implement demand‑control ventilation, hood fan speed control, occupancy‑based restroom exhaust, and carbon monoxide/nitrogen dioxide sensor arrays for garages. Our controls integrate with your building automation system (BACnet/Modbus), enabling scheduling, alarms, and trend logging for easy management and compliance reporting.

Quiet, Smooth, and Reliable Operation

We address sound power, vibration, and balance from day one. Isolation bases, spring hangers, and flexible connectors minimize structure‑borne noise. Proper wheel and belt alignment, sheave sizing, and on‑site air balancing deliver quiet, stable airflow that protects comfort and productivity in adjacent spaces.

Commercial Kitchen Exhaust Expertise

From quick‑serve to high‑volume dining, we deliver UL 762 grease fans, curb packages, and high‑temperature duct, with grease containment, hinge kits, roof protection, and interlocked make‑up air. We design to capture velocity and hood type, reduce smoke spillage, and improve hood face comfort — all while complying with NFPA 96 and local fire authority requirements.

Maintenance and Rapid Repairs

Protect your investment with proactive service plans: cleaning, belt and bearing checks, lubrication, alignment, motor amperage checks, vibration inspection, and airflow verification. If something fails, our factory‑trained technicians diagnose and repair fans, motors, VFDs, contactors, sensors, and controls quickly — with OEM or high‑quality replacement parts to restore uptime fast.

Factory‑Trained, Brand‑Agnostic Expertise

Our engineers are factory‑trained by Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier. We apply cross‑manufacturer best practices to select the right fan and controls for your application — not just a single catalog solution — delivering performance, reliability, and total cost of ownership advantages.
