Commercial, Hospital & Lab Ventilation in Calabasas

Engineered Ventilation for Critical Environments

Healthcare and laboratory spaces demand far more than comfort cooling. We engineer ventilation that protects patients, staff, and research—from operating rooms and sterile compounding pharmacies to BSL labs, imaging suites, and university research facilities. Our designs establish correct air changes per hour (ACH), pressure relationships, filtration levels, and air distribution patterns to reduce infection risk and control contamination.

Compliance-Driven Design, Built for California

Our team designs and installs systems aligned with ASHRAE 170, California Title 24, NFPA 99, CDC guidelines, and USP 797/800 for sterile and hazardous drug handling. We prepare submittals and work HCAI/OSHPD pathways as needed, coordinating ICRA containment for work in active healthcare settings. Whether you operate a hospital, outpatient clinic, dental/surgical center, compounding pharmacy, biotech lab, or cleanroom, we deliver code‑ready documentation and commissioning results you can rely on.

Key Technical Capabilities

• Pressure control: negative and positive pressure rooms with monitored differential setpoints and alarms.
• Filtration: MERV 13+, HEPA, and ULPA options; leak testing and integrity reporting available.
• Airflow & distribution: laminar flow diffusers for sterile zones; proper air change rates for ORs, isolation rooms, and labs.
• Exhaust systems: fume hoods, BSCs, general lab exhaust with energy recovery and corrosion‑resistant components where required.
• Energy & resilience: ERVs/heat recovery, variable speed fans, VAV, demand control ventilation, and N+1 strategies for mission‑critical uptime.
• Controls & visibility: BMS integration, continuous monitoring of pressure/ACH/temperature/humidity, and trend logging for compliance audits.
• California readiness: seismic supports, noise/vibration control, and Title 24 acceptance testing.

Design–Build Delivery That Reduces Risk

We start with a thorough site assessment and load/ventilation calculations, then develop stamped drawings and equipment schedules. Our team manages permitting, coordinates with architects/GCs via BIM when required, and sequences work to minimize downtime. During construction, we implement ICRA barriers, negative air containment, and HEPA scrubbing to protect occupied areas. On completion, we perform TAB, functional performance testing, and owner training. You receive a closeout package with setpoints, as‑built drawings, commissioning results, and maintenance recommendations.

Service, Maintenance, and 24/7 Emergency Response

Critical spaces can’t afford uncertainty. We offer proactive maintenance programs tailored to hospitals and labs: scheduled filter changes, HEPA integrity checks, sensor calibration, damper verification, alarm testing, and cleaning of coils/fans/ERV cores. Our on‑call team is available 24/7 for urgent repairs, temporary pressurization solutions, and rapid parts sourcing to restore compliance and operations fast.

Manufacturer‑Trained Craftsmanship

Our fourth‑generation, family‑owned team has 80+ years of engineering heritage. Field engineers and installers are factory trained by leading manufacturers including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That depth helps us match equipment to application and integrate multi‑vendor systems that meet performance and budget targets without compromising safety.
