Commercial Ventilation System Installation in Oxnard, CA

Engineered Ventilation Solutions for Oxnard Businesses

From coastal humidity to high-occupancy demands, Oxnard facilities require ventilation designs that deliver clean air, correct pressurization, and energy efficiency. #1 AC Guys specializes in commercial ventilation system installation tailored to Ventura County codes, climate, and industry needs. Our mission is simple and steadfast: healthier indoor air for healthier work and better outcomes.

What We Install

• Dedicated outdoor air systems for controlled ventilation and dehumidification (DOAS).
• Energy recovery ventilators and heat recovery ventilators for high-efficiency fresh air (ERV and HRV).
• Make-up air units to maintain balanced building pressure and replace exhausted air.
• Kitchen hood exhaust, grease duct, and make-up air for restaurants and commercial kitchens.
• Rooftop packaged units with economizers and demand-control ventilation.
• Warehouse and industrial ventilation, including high-bay dilution, spot exhaust, and destratification.
• Bathroom and general exhaust systems, stairwell pressurization, and parking garage exhaust with CO and NO2 sensors.
• Filtration upgrades including MERV 13 and higher, and options for advanced IAQ technologies where appropriate.

Our Engineering-First Process

• Discovery and assessment: occupancy, process loads, contaminants of concern, noise and space constraints, utility rates, and budget targets.
• ASHRAE 62.1 and California Title 24 ventilation calculations to right-size airflow and optimize energy use.
• Duct design, air distribution, and controls strategy for balanced supply, exhaust, and pressurization by zone.
• Permitting support with Ventura County and City of Oxnard building departments, including mechanical, electrical, and structural details as needed.
• Seismic bracing, curb and support design, and roof coordination per California requirements.
• Professional installation with clean workmanship, site safety, and minimal downtime scheduling.
• Controls integration and commissioning for setpoint verification, economizer sequence, and demand-control ventilation.
• Testing, adjusting, and balancing (TAB) for verified airflow, static pressure, and noise criteria compliance.
• Documentation, owner training, and post-install performance check-ins.

Designed for Codes, Comfort, and Costs

Our systems are built to satisfy California Mechanical Code, Title 24 energy standards, and ASHRAE 62.1 for acceptable indoor air quality. We prioritize:
• Proper outside air dilution and filtration to reduce airborne contaminants and odors.
• Stable building pressurization to prevent infiltration and humidity problems.
• Energy recovery where it pays back, reducing heating and cooling loads.
• Controls strategies that limit runtime and peak demand without sacrificing fresh air.
• Quiet operation and thoughtfully placed equipment to support occupant comfort and productivity.

Industries We Serve
