Commercial Exhaust Fan Installation, Repair & Maintenance in Oxnard, CA

Complete Commercial Exhaust Solutions, Built for Oxnard Businesses

Your facility’s ventilation is the backbone of indoor air quality and safety. At #1 AC Guys, we engineer, install, and service commercial exhaust fans that move air efficiently, control contaminants, and meet strict California codes. As a 4th‑generation, family‑run HVAC team with 80+ years of engineering experience, we thrive on large, complex, and time‑sensitive projects for restaurants, food processing, manufacturing, retail, schools, and healthcare spaces in Oxnard and throughout Ventura County.

What We Design, Install, and Service

• Rooftop upblast and centrifugal exhaust fans for kitchens and grease applications (NFPA 96).
• Inline and mixed‑flow fans for long duct runs and noise‑sensitive areas.
• Wall‑mounted propeller fans for high‑volume general exhaust.
• Fume and process exhaust for labs, light manufacturing, and warehouses.
• Demand‑controlled ventilation with VFDs, sensors, and smart controls.
• Make‑up air integration, hoods, ductwork, curb adapters, and seismic bracing.
• Testing, adjusting, and balancing (TAB) to verify performance after install or repair.

Compliance, Safety, and Documentation

We deliver code‑ready solutions aligned with California Mechanical Code, IMC, Title 24, OSHA, and NFPA 96 for commercial kitchens. Our team manages permitting, submittals, and closeout documentation, including airflow reports and as‑built drawings when needed. We also coordinate with hood suppression contractors and local inspectors to streamline approvals and reduce downtime.

Industries We Serve

• Restaurants, ghost kitchens, and food halls (grease‑rated, rooftop upblast).
• Manufacturing and light industrial (process exhaust, heat and smoke removal).
• Retail and shopping centers (quiet, energy‑efficient general exhaust).
• Schools, gyms, and offices (odor and CO2 control, balanced ventilation).
• Healthcare, labs, and R&D (fume extraction, filtration, pressurization support).

Our Proven Process

1) Site assessment and airflow calculations to right‑size equipment and avoid noise or negative pressure issues.
2) Engineering, product selection, and value engineering to meet performance and budget goals.
3) Professional installation with curb modifications, electrical, controls, seismic supports, and weatherproofing.
4) Startup, VFD tuning, and TAB to confirm design airflow and pressure targets.
5) Training for your staff and a maintenance plan tailored to your hours and load profile.

Preventive Maintenance That Pays Off

Grease, dust, and worn belts silently rob airflow and efficiency. Our recurring PM includes cleaning and degreasing where applicable, belt and bearing checks, motor amp draws, vibration checks, and control calibration. Proactive service reduces energy use, prevents premature failures, and protects warranties—especially critical for kitchens and high‑heat processes.

Factory‑Trained, Brand‑Agnostic Expertise

Our engineers and technicians are factory‑trained by leading global manufacturers such as Fujitsu (Japan), Mitsubishi Electric, Midea, Gree, and Haier. We service and install all major commercial ventilation brands frequently found in Oxnard—such as Greenheck, CaptiveAire, Loren Cook, and more—selecting the best fit for your application, not just a single brand lineup.
