Commercial Hospital-Grade Air Sterilization in Ontario, CA

What Hospital-Grade Means for Commercial IAQ

Hospital‑grade air sterilization goes beyond standard filtration. It blends high‑efficiency capture of fine particles with verified inactivation of microorganisms in the airstream and on coils, plus controlled ventilation and pressure strategies. In Ontario, CA, that means combining HEPA or high‑MERV filtration, UVC germicidal irradiation, and right‑sized outdoor air to deliver healthier, more comfortable, and code‑aligned spaces for staff and guests.

Engineer‑Led Design, Built Around AC PRO

We specify and source through AC PRO to ensure top‑tier IAQ hardware, filters, and UVGI components are available when you need them. Our fourth‑generation family of engineers (80+ years of engineering experience) leads each project from feasibility to commissioning, optimizing your existing HVAC assets and upgrading only where it moves the needle. Our team has trained at the factories of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China) to master system integration and commissioning on these platforms.

Sterilization Technologies We Deploy

• HEPA H13/H14 terminal filtration or fan‑filter units for critical zones; MERV 13–16 upgrades for central systems.
• UVGI (UVC 254 nm): in‑duct airstream and coil irradiation; upper‑room UVGI with safety shielding where appropriate.
• Dedicated outdoor air with energy recovery to boost Equivalent Outdoor Air while controlling humidity and energy use.
• Pressure zoning and negative‑pressure rooms for isolation areas, with sealed ductwork and verified leakage class.
• Activated carbon for odor/VOC reduction and coil cleanliness strategies to sustain performance.
• Continuous IAQ monitoring (CO2, PM2.5, tVOC, temperature, RH) with BMS integration and alerts.
• Optional bipolar ionization or PCO only upon request and with third‑party performance data for the specific application.

Compliance, Documentation, and Verification

Our designs align with ASHRAE 241 and 62.1, California Title 24, and applicable local codes. We provide stamped drawings as needed, submittals, IOMs, UV safety calculations, and filter loading curves. Commissioning includes measured airflow, pressure mapping, UV irradiance inactivation zones, and baseline IAQ data. You receive a clear verification report and a maintenance plan to keep performance on spec.

Our Process

• Assessment: On‑site survey in Ontario, CA; risk and occupancy profiling; energy and code review.
• Design: Load calculations, EOA analysis, filtration and UVGI layouts, controls, and phased implementation options.
• Install: Cleanroom‑minded work practices, isolation during tie‑ins, and after‑hours scheduling to minimize downtime.
• Commission: Test and balance, UVGI validation, sensor calibration, and owner training.
• Maintain: Filter and lamp schedules, periodic IAQ reporting, and remote monitoring.
