Commercial Hospital‑Grade Air Sterilization in Pasadena

Engineered, Not Just Installed

Every building breathes differently. We begin with a technical survey—airflow mapping, return and supply locations, existing filtration, coil condition, static pressure, controls, occupancy, and energy targets. Then we design a solution that meets your IAQ goals while protecting capacity and efficiency, providing stamped drawings when required and a clear sequence of operations.

Technologies We Specify for Hospital‑Grade Outcomes

• UV‑C/UVGI: In‑duct and upper‑air fixtures to deactivate airborne microorganisms and keep coils biofilm‑free, designed for proper dose, dwell time, and safety.
• HEPA H13/H14: Medical‑grade filtration in standalone housings or fan filter units, with pre‑filter staging to preserve lifespan and maintainable pressure drop.
• Activated Carbon & Specialty Media: Target VOCs and odors with correctly sized media beds and change‑out schedules.
• Photocatalytic Oxidation (PCO): Applied where VOC control is needed, engineered to manage byproducts and contact time.
• Bipolar Ionization (as appropriate): Deployed only when it supports the engineering case and complies with current guidance and third‑party test data.

We integrate these layers with AC PRO–specified components, smart sensors, and ventilation strategies so your system can be monitored, maintained, and verified.

Compliance and Best Practices

Our designs align with ASHRAE 62.1 ventilation guidance and applicable Title 24 requirements, and are built with safety and serviceability in mind. For healthcare‑adjacent spaces we reference ASHRAE 170 principles where appropriate. We coordinate with your facilities team on lockout/tagout, UV shielding, and access requirements, and we document commissioning so you can prove performance.

Built for Pasadena Facilities

From historic masonry buildings along Colorado Blvd. to modern glass offices, we match sterilization strategies to your envelope, hours, and occupancy. We plan for wildfire smoke events, seasonal particulates, and local AQMD conditions—ensuring filtration, outdoor air, and pressurization work together without sacrificing comfort or energy.

AC PRO Integration & Supply Chain Strength

Projects stay on schedule because we standardize around AC PRO–specified housings, filter racks, fan arrays, and serviceable components, with strong regional availability across Los Angeles County. This minimizes lead‑time risk, simplifies spares, and helps facilities teams maintain uptime.

Industries We Serve

• Medical offices, outpatient clinics, and labs
• Schools, higher education, and libraries
• Corporate offices and data‑adjacent spaces
• Hospitality, retail, and mixed‑use
• Food service and light manufacturing

We excel at large and complex projects—multi‑zone retrofits, negative‑pressure rooms, and 24/7 operations where downtime is not an option.

Our Process

• Assessment: Site walk, measurements, and IAQ goals.
• Engineering: Load checks, device selection, and drawings.
• Build: Safe installation with containment where needed.
• Commissioning: Verify airflow, pressure, UV dose, and filtration.
• Training & Handover: O&M docs, spare parts, and schedules.
• Maintenance: Filter changes, UV lamp lifecycle, cleaning, and periodic performance reviews.

Why #1 AC Guys

We are a 4th‑generation family of engineers with 80+ years in engineering, factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). Our mission is healthy air for a healthy life—and that means solutions that are measurable, maintainable, and code‑aligned. We stand behind our work with clear warranties and responsive service.

Monitoring and Verification

We can integrate sensors for PM2.5, TVOCs, CO2, temperature, and humidity, with BAS connectivity (BACnet/Modbus) for continuous awareness. Trending helps you validate improvements, schedule maintenance, and demonstrate compliance to stakeholders.

Important Note

Hospital‑grade air sterilization systems are designed to reduce airborne contaminants and improve indoor air quality; they are not medical devices and do not guarantee disease prevention. Performance depends on design, installation, operation, and maintenance.

Service Area and Scheduling

Based in Los Angeles, we serve Pasadena, all of Los Angeles County, and nearby Orange County, Ventura County, and Western Riverside County. We offer prompt site assessments and phased installations to minimize downtime.
