Commercial Hospital-Grade Air Sterilization in Los Angeles

Our mission is healthy air for a healthy life—and we bring 80+ years of cross‑disciplinary engineering to every commercial air sterilization project. Whether you manage a high‑rise, campus, clinic, studio or retail chain, our hospital‑grade approach elevates indoor air quality (IAQ) with measurable results while optimizing energy and lifecycle costs.

What “hospital‑grade” means in commercial settings

Hospital‑grade air sterilization combines multiple strategies to help reduce airborne pathogens, fine particulate and odors. In commercial buildings, we tailor these strategies to occupancy, risk profile, and code requirements—designing systems that align with ASHRAE recommendations (including 241‑2023 for infectious aerosols where applicable) and local regulations.

• UVGI (UVC) in‑duct and upper‑air systems for pathogen inactivation
• Medical‑grade HEPA H13/H14 filtration and high‑MERV upgrades
• Outside air optimization and verified air changes per hour (ACH)
• Engineered pressure control (e.g., isolation/clean zones)
• Active air treatment options such as bipolar ionization, with monitoring
• Continuous IAQ sensing: PM2.5, CO2, TVOC, temperature and humidity
• Smart controls, BMS integration and demand‑controlled ventilation

Technologies we deploy and integrate

UVGI (UVC): Engineered exposure, dwell time and intensity for coils and airstreams. Upper‑room UVGI adds an extra layer in high‑traffic areas.
HEPA & high‑MERV filtration: HEPA H13/H14 modules and right‑sized fans to maintain airflow and static pressure targets.
Ventilation & ACH: Outside air strategies for clean air delivery rates that support CDC/ASHRAE guidance—without sacrificing comfort.
Advanced ionization: Select applications of bipolar/needlepoint ionization, paired with IAQ monitoring and compliance documentation.
Portable adjuncts: Commercial mobile HEPA/UV units for phased upgrades or event‑driven needs.

Engineered for your building

Every site starts with a data‑driven assessment: load calculations, airflow mapping, pressure zoning, filtration impacts, and energy modeling. We design for performance and reliability, then validate with commissioning, balancing, and IAQ baselines you can track.

• Retrofit and new construction for offices, hospitality, schools, gyms and healthcare‑adjacent spaces
• VRF/ductless, split, packaged and central plant systems
• Title 24 and local code alignment; fire/smoke, electrical and UL/NFPA coordination
• BMS integration (schedules, alerts, demand control, trend logs)
• Noise and vibration control built into selections

Why #1 AC Guys

We’re a 4th‑generation family of engineers with 80+ years of engineering experience, trusted on large and complex commercial projects across Southern California. Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China) and Haier (China). This deep OEM knowledge lets us integrate hospital‑grade air strategies into VRF, ductless and central systems for maximum reliability and efficiency.

• Turnkey delivery—from concept and permits to installation and commissioning
• Clear ROI: energy, filter life, maintenance and productivity considerations
• Minimal downtime with phased installs and off‑hours work
• Detailed documentation: submittals, as‑builts and IAQ reports
• Flexible maintenance plans, filter logistics and UV lamp schedules

Industries we serve

Corporate offices and coworking, medical and dental suites, labs and R&D, schools and higher education, fitness and wellness, restaurants and hospitality, manufacturing and clean areas, retail and entertainment, studios and post‑production. We tailor risk‑based designs—from lobby reception and conference rooms to locker rooms, kitchens and treatment areas.

Our process

• Assessment: site survey, IAQ baselines, risk zoning, code review
• Design: technology selection, ACH targets, sequences of operation
• Proposal: options, schedules, phasing, budget and ROI
• Installation: safety, QA/QC, BMS tie‑ins, commissioning
• Validation: balancing, sensor calibration, performance documentation
• Care plan: maintenance schedule, staff training and remote monitoring

Service area

We proudly serve Los Angeles County and nearby regions including Orange County, Ventura County and Western Riverside County. Rapid response teams are staged for multi‑site portfolios and time‑critical upgrades.

Compliance and transparency

We align designs with ASHRAE and local codes, provide manufacturer specifications, and document verification steps. While no system can guarantee total elimination of airborne pathogens, our hospital‑grade approach is engineered to meaningfully reduce risk and improve perceived air quality—supported by data you can see.
