Commercial Hospital & Lab Ventilation in Downey

Engineered for compliance, patient safety, and research integrity

Healthcare and laboratory environments demand more than comfort cooling. Our Downey team engineers ventilation that is purpose‑built for clinical outcomes and scientific rigor: stable pressure differentials, verified filtration, and repeatable air change rates. We design to meet ASHRAE 170 and California Title 24 requirements, prepare clear submittals for HCAI review where applicable, and coordinate infection control risk assessments (ICRA) to keep projects on track and safe.

Our mission is simple: healthy air for healthy lives. That means designing systems that protect patients, staff, and research by controlling contaminants at the source, ensuring directional airflow, and documenting performance with commissioning and balancing data.

What we deliver

• Hospital ventilation: ORs, PACU, NICU, isolation (AIIR), anterooms, sterile processing, imaging suites
• Laboratory ventilation: BSL spaces, vivariums, fume hood exhaust and makeup air, cleanrooms, gene therapy suites
• Filtration and air treatment: HEPA/ULPA banks, UV‑C options, humidity control, energy recovery
• Controls and monitoring: VAV and pressure control, DDC/BMS integration, continuous IAQ and differential pressure monitoring
• Design‑build and retrofits: concept, load calcs, submittals, permitting support, installation, test, adjust, balance (TAB)
• Commissioning and validation: functional testing, trending, reports for surveys and audits
• Service and maintenance: preventive programs, filter changes, calibration, emergency response

Every solution is tailored: isolation rooms require dependable negative pressure, while sterile spaces maintain tight positive pressure to keep contaminants out. We size outdoor air precisely, model coil and filter pressure drops, and design duct systems to control noise and velocity—so the right air reaches the right place, every time.

AC PRO integration and preferred technologies

On request, we source AC PRO‑compatible equipment and components, aligning selections with your facility standards and procurement preferences. For specialty applications, we apply our factory training at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China) to integrate advanced technologies where appropriate—such as high‑efficiency heat pumps for ancillary spaces or VRF support zones—always maintaining hospital‑grade ventilation for critical areas.

We coordinate air handlers, rooftop units, exhaust systems, terminal devices, and controls so the entire system works as a unified platform. Data points and alarms are mapped into your BMS, giving your team real‑time visibility of pressure, airflow, and filter status.
Result: higher resilience, faster troubleshooting, and lower lifecycle cost.

Our process

• Assessment and planning: site walk, code matrix, risk assessment, and design criteria
• Engineering and submittals: drawings, sequences of operation, equipment schedules, and controls integration
• Construction and controls: clean install practices, ICRA coordination, rigorous QA/QC
• Startup and commissioning: point‑to‑point, functional tests, TAB, pressure/ACH verification
• Training and turnover: O&M docs, staff training, trend logs, and PM schedules

From the first conversation to final sign‑off, you’ll have a single accountable team and clear communication. We document what we build, and we prove that it performs.
