Commercial Exhaust Fans in Orange, CA — AC PRO–Compatible Service

When your building depends on dependable exhaust, you need more than a swap‑and‑go contractor. You need an engineering‑first partner who can size, select, and commission commercial exhaust fans that perform under real‑world loads. That’s where #1 AC Guys comes in for Orange, CA businesses.

What we service and install

• Upblast rooftop exhaust fans for commercial kitchens (grease and heat)
• Inline centrifugal and mixed‑flow fans for long duct runs and tight mechanical rooms
• Tube‑axial and vane‑axial fans for warehouses, manufacturing, and process exhaust
• Wall‑mount and utility sets for light commercial applications
• Parking garage exhaust with CO/NO2 demand control ventilation
• Lab and specialty exhaust, spark‑resistant and high‑temperature options

We integrate AC PRO–supplied fans, motors, curbs, curb adapters, and controls, ensuring proper fit, drive matching, vibration isolation, and weatherproofing. Our team validates airflow against design CFM and static pressure and balances the system so air moves exactly where it should.

Engineer‑led process that prevents callbacks

• Assessment: Site survey, as‑built review, duct/shaft evaluation, and electrical checks
• Design: Fan selection, CFM and ESP calculations, acoustics, and energy code inputs
• Installation: Rigging, curb and adapter work, grease duct tie‑ins, sealed penetrations
• Controls: VFDs, pressure/CO/NO2 sensors, make‑up air interlocks, BMS integration
• Commissioning: Airflow verification, vibration testing, controls tuning, TAB reports
• Maintenance: Bearings, belts, lubrication, motor amps, alignment, and cleaning

Every project targets compliance with California Title 24, local Orange/Orange County permitting, ASHRAE ventilation standards, NFPA 96 (for kitchen systems), and OSHA best practices. We document our work so inspections go smoothly and your records are audit‑ready.

AC PRO–compatible from day one

Whether you’re replacing a failed unit or upgrading capacity, we match new fans to AC PRO–supplied equipment and accessories for reliable operation and streamlined service. We verify motor sizing, wheel type, RPM, and curb fit to avoid performance losses and premature wear.
Need a curb adapter or an emergency motor swap? We source and install quickly to keep your space safe and open for business.

Industries we support in Orange

• Restaurants, food halls, and commercial kitchens (with make‑up air pairing)
• Manufacturing, distribution, and cold storage
• Healthcare, clinics, and life‑science labs
• Retail, offices, mixed‑use, and multifamily common areas
• Auto shops and parking structures

Common symptoms we fix: fan won’t start, low CFM, excessive heat or odors, grease blow‑by, tripped breakers, vibration and noise, belt dust, bearing failure, and roof leaks around curbs. We address root causes—duct restrictions, incorrect wheel selection, unbalanced sheaves, negative building pressure—so the problem stays solved.

Energy, comfort, and IAQ—balanced

Right‑sized exhaust protects people and product while eliminating wasted energy. We deploy VFDs for part‑load control, demand sensors for kitchens and garages, and EC motor upgrades where applicable. Balanced with make‑up air, your space avoids drafts, door blow‑open, and combustion safety issues—improving comfort and indoor air quality.
