Commercial Hospital-Grade Air Sterilization in Los Angeles

When the stakes are high, you need more than a contractor—you need engineers who understand airflow physics, contamination control, and code compliance. #1 AC Guys designs and implements commercial hospital-grade air sterilization systems across Los Angeles County and nearby Orange County, Ventura County, and Western Riverside County, delivering healthier indoor environments without sacrificing comfort or efficiency.

What “hospital-grade” really means

Hospital-grade air sterilization targets measurable reductions in airborne pathogens via a layered approach—ventilation, filtration, UV-C irradiation, and pressurization. Our designs are aligned with current best practices, including ASHRAE Standard 241 (Control of Infectious Aerosols) and ASHRAE 62.1 ventilation guidance, while following California Mechanical Code and local jurisdiction requirements. Typical strategies include 6–12+ air changes per hour (space-dependent), HEPA or MERV-13/16 filtration, coil and airstream UVGI, and negative or positive pressure zones as needed.

Technologies we deploy

• HEPA and MERV-13/16 filtration: Staged filtration (pre, final, HEPA) to capture fine particulates down to 0.3 µm at 99.97% efficiency for HEPA-equipped systems.
• UV-C/UVGI: Coil surface irradiation, in-duct UV-C, and upper-air UVGI to inactivate airborne microorganisms. We design lamp placement and dose to meet application targets and safety constraints.
• Bipolar ionization (UL 2998 ozone-free options): Carefully selected solutions that enhance particulate agglomeration and address certain VOCs; applied judiciously and validated under real operating conditions.
• Ventilation & ACH upgrades: Outdoor air optimization, ERV/HRV integration, and demand control ventilation to balance IAQ and energy use.
• Pressurization & zoning: Negative pressure rooms for isolation, positive pressure for clean areas, and anteroom strategies to control airflow pathways.
• Controls & monitoring: BACnet/Modbus integration, IAQ dashboards, and sensors (CO₂, PM2.5, TVOCs, temp/RH) to visualize performance and guide continuous improvement.

Our engineered process

• Assessment: On-site survey of mechanical systems, load profiles, duct conditions, occupancy patterns, and code constraints. We also review existing IAQ data if available.
• Design & modeling: Airflow calculations, pressure mapping, ACH targets, filtration selections, UVGI dose planning, and control sequences tailored to your spaces.
• Build & integration: Clean installs and retrofits with careful phasing to minimize downtime. We source premium equipment through AC PRO for fast availability and reliable logistics.
• Commissioning: Functional testing, balancing, and verification of filtration pressure drops, UV-C output, ventilation rates, and setpoint adherence.
• Verification & reporting: IAQ snapshots, trend logs, and owner training so your team understands how to operate and sustain performance.

Design details that matter

We pay attention to the details that determine real-world outcomes: duct leakage, filter rack integrity, coil face velocity, bypass risk, UV-C reflectivity, lamp aging, noise, vibration, and pressure cascades between zones. Controls are tuned to maintain stable setpoints and alarm on drift, while energy recovery and scheduling limit operating costs. Where applicable, we specify sealed HEPA housings, gasketed access doors, and verifiable UV-C irradiance levels.

Compliance-friendly documentation

From permit-ready submittals to commissioning reports, our documentation supports your internal standards and landlord or AHJ requirements. We aim for transparency—what’s installed, how it’s configured, and how it performs—so your team and stakeholders have confidence in the results.

Service area coverage

We proudly serve Los Angeles County (including Downtown LA, Westside, South Bay, San Fernando Valley, San Gabriel Valley, Pasadena, Glendale, Burbank, Santa Monica), plus Orange County (Anaheim, Irvine, Santa Ana), Ventura County (Thousand Oaks, Oxnard, Ventura), and Western Riverside County (Corona, Temecula, Riverside-west).

Results you can measure

Our goal is clean, healthy air backed by data. We design for target ACH and filtration efficiency, validate airflow and pressure differentials, and enable IAQ monitoring so you can see improvements over time. While no solution can guarantee elimination of all contaminants, our engineered systems are built to help reduce risk and support a healthier, more productive environment.
