• Economizer and energy recovery retrofits for cleaner, lower-cost air
• Planned shutdowns and live environment phasing to protect operations

Healthcare Ventilation Expertise

Hospitals and ambulatory facilities in Oxnard rely on predictable, clean airflow. We design and maintain systems intended to meet ASHRAE 170 room classifications while supporting infection prevention and clinical workflows. Our team balances pressure relationships, filtration, and comfort to keep spaces safe and staff productive.

• Isolation suites (AIIR/PIIR) with robust pressure control and monitoring
• Operating rooms with laminar flow diffusers and tight thermal tolerances
• Sterile processing, endoscopy, imaging, and dental suites
• Pharmacy compounding (USP 797/800) ventilation and room offsets
• NICU, PACU, med-surg, and outpatient care areas

Laboratory Ventilation and Containment

From university labs to private R&D spaces, we deliver ventilation that supports accurate results and researcher safety. We tune fume hood diversity factors, track hood usage, and stabilize room offsets so spaces remain in spec even under dynamic loads.

• BSL‑1 to BSL‑3 support, pressure cascade design, and alarming
• Fume hood exhaust systems, manifolded or dedicated
• Room pressurization with continuous differential monitoring
• HEPA/ULPA filtration and clean supply strategies for sensitive zones
• Emergency purge modes and safe shutdown sequences

Design-Build and Complex Retrofits

We thrive on complex, occupied retrofits where uptime and safety are nonnegotiable. Our process reduces risk and shortens timelines while keeping clinical and lab operations running.

• Needs assessment, existing conditions surveys, and airflow baselining
• Concept design, equipment selection, and York integration planning
• HCAI submittal support, coordinated phasing, and ICRA containment
• Installation with infection control barriers and negative work zones
• Functional performance testing, TAB, and operator training

Maintenance, Monitoring, and 24/7 Response

Precision ventilation requires vigilant care. We offer proactive maintenance plans and real-time monitoring that help prevent drift, preserve pressure relationships, and cut energy waste. When issues arise, our Oxnard team responds 24/7 to stabilize environments fast.

• Filter programs (pre, HEPA/ULPA), sensor calibration, and leak checks
• Fan arrays, belts, drives, and bearing service for quiet reliability
• Coil cleaning and water/condensate management to protect IAQ
• Controls tuning, trending, and remote alarms for early detection
• KPIs: uptime, pressure stability, ACH, and energy intensity
