Commercial Hospital & Lab Ventilation in Oxnard

Purpose‑Built Ventilation for Healthcare and Science

In medical and laboratory environments, air is a critical asset. #1 AC Guys designs, installs, and maintains ventilation systems in Oxnard that control contamination, odors, airborne hazards, and cross‑infection. We engineer stable temperature, humidity, filtration, and pressurization—so your teams can work with confidence and your facility can meet inspections without surprises.

What We Deliver

Design‑Build and Upgrades: Clean, code‑compliant ventilation for operating rooms, treatment spaces, pharmacies (USP 797/800), isolation suites, procedure rooms, imaging suites, dental and outpatient clinics, university and private labs, and cleanrooms (ISO classifications). We right‑size systems for target ACH, thermal loads, and lifecycle cost.

HEPA Filtration and Airflow Control: From MERV 13+ through HEPA, with laminar flow options where needed. We implement negative pressure for isolation and hazardous drug spaces, and positive pressure for ORs, clean benches, and cleanrooms—backed by real‑time differential pressure monitoring.

Exhaust & Specialty Ventilation: Fume hoods, biosafety cabinets, canopy hoods, and dedicated exhaust with proper dilution, capture velocity, and energy recovery when appropriate.

Controls & Monitoring: Building automation, room‑level sensors, and alarming for pressure, temperature, humidity, and filter status. Remote visibility keeps your team ahead of drift and downtime.

Commissioning, TAB & Validation: We verify air changes, pressure cascades, filtration performance, and sequences of operation—delivering documentation for surveys and audits.

Built for Compliance in California

Our systems are engineered to meet or exceed ASHRAE 170 for healthcare ventilation, the California Mechanical Code, Title 24 energy standards, NFPA 99 for healthcare facilities, USP 797/800 for sterile and hazardous drug compounding, and applicable CDC and ISO cleanroom guidance. We support HCAI (formerly OSHPD) submittals and coordinate with the City of Oxnard and Ventura County for smooth permitting.

Expertise You Can Count On

We are a 4th‑generation family company with more than 80 years of engineering experience. Our team is factory‑trained by leading manufacturers including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That means better equipment integration, smarter controls, and faster issue resolution across both new and legacy systems.

Large and Complex Projects—Made Manageable

From multi‑suite renovations to new wings and lab build‑outs, we excel at phasing, ICRA containment, and infection‑control construction practices that keep your facility operational. We plan around your peak schedules, stage temporary filtration and pressure control when needed, and deliver clean turnover with airtight documentation.

Energy and Reliability

We balance clinical performance with efficiency: VAV strategies, heat recovery, demand‑controlled ventilation, high‑efficiency ECM fans, and right‑sized filtration paths that reduce static while protecting air quality. Robust parts selection and preventive maintenance minimize unplanned downtime and total cost of ownership.

Service, Maintenance, and 24/7 Emergency Response

Protect your investment with proactive maintenance, periodic TAB, and calibration of sensors and alarms. Our Oxnard‑area rapid response teams troubleshoot pressure alarms, IAQ complaints, odor events, control faults, and equipment failures any time of day or night.
