Commercial Hospital-Grade Air Sterilization in Fontana

Healthy air drives healthy business. For Fontana facilities, we deliver hospital‑grade air sterilization by combining robust ventilation, advanced filtration, and active airstream disinfection—seamlessly integrated with Lennox commercial HVAC equipment to elevate indoor air quality (IAQ) without sacrificing energy performance.

What “hospital-grade” means in practice

Hospital‑grade air sterilization is a design approach built on proven technologies and tight execution: UV‑C germicidal irradiation for coils and airstreams, HEPA H13/H14 filtration for critical zones, MERV 13–16 upgrades for systemwide capture, and controlled outdoor air with proper pressurization. Results depend on correct sizing, placement, sealing, and commissioning—areas where our fourth‑generation engineering team excels.

• UV‑C airstream and coil irradiation to disrupt microbial growth
• HEPA H13/H14 point‑of‑use or bypass modules for high‑risk spaces
• MERV 13–16 filter upgrades with pressure‑drop management
• Ventilation tuned to ASHRAE 62.1 and healthcare‑oriented guidance
• Optional bipolar ionization and activated carbon for VOCs and odors

Lennox commercial integration, done right

We design, retrofit, and maintain Lennox rooftop units and split systems to support advanced IAQ. Our work includes economizer optimization, demand‑control ventilation, energy recovery (ERV), and filtration upgrades that respect fan curves and static pressure limits. For many sites, we add HEPA bypass modules, in‑duct UV‑C arrays, and Lennox‑compatible controls for scheduling, alarms, and remote monitoring.

• Rooftop unit retrofits with MERV 13–16 and UV‑C
• HEPA modules for procedure rooms, dental ops, and labs
• Controls integration (BACnet/automation) for IAQ visibility
• Air balancing and test‑and‑balance reports for verification

Designed by engineers who solve the hard problems

#1 AC Guys is a family business of engineers in its fourth generation with 80+ years in engineering. We use load calculations, duct design, and airflow modeling to achieve target air changes per hour, pressure relationships, and temperature/humidity stability. Expect tight duct sealing, proper filter racks, drain‑pan UV‑C placement, and commissioning documents you can trust.

Sectors we serve in Fontana

• Medical offices, dental suites, labs, and diagnostic centers
• Schools, universities, and childcare facilities
• Offices, call centers, retail, and mixed‑use
• Food processing, light manufacturing, and logistics hubs
• Gyms, studios, and assembly spaces seeking cleaner air

Our end-to-end process

1) Site assessment and IAQ baseline. 2) Engineering and submittals with Lennox integration details. 3) Installation and retrofit with safety and cleanliness protocols. 4) Commissioning, balancing, and owner training. 5) Ongoing maintenance with filter logistics, UV‑lamp changeouts, and performance checks.

Compliance and best practices

We align designs to ASHRAE 62.1 for ventilation and healthcare‑oriented best practices such as ASHRAE 170‑style pressurization and filtration where applicable, along with California Title 24 energy standards. Our goal is to improve IAQ while managing energy use through DCV, ERV, and proper economizer controls.

Factory training, proven craftsmanship

Our engineers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We apply that discipline across the brands we service and integrate—bringing attention to detail that protects your investment and elevates IAQ outcomes.

Service area

Based in Greater Los Angeles, we serve Fontana and the Inland Empire, along with Los Angeles County and nearby regions including Orange County, Ventura County, and Western Riverside County, as well as neighboring San Bernardino County communities.

Results you can measure

We provide commissioning and optional IAQ trending for PM2.5, CO2, VOCs, temperature, and humidity. Clear reports demonstrate ventilation rates, filter performance, and UV‑C operation, helping your team meet internal policies and stakeholder expectations.

Maintenance and lifecycle support

Hospital‑grade IAQ is sustained through consistent care. We tailor service plans for Lennox systems—filter cadence, UV‑lamp replacement, coil cleaning, and controls verification—to maintain airflow, efficiency, and disinfection performance through every season.

Make the air in your building work for you

If your Fontana facility needs a retrofit, a ground‑up design, or a compliance‑driven upgrade, #1 AC Guys delivers fast mobilization, clean installations, and engineer‑level commissioning. Let’s design a solution that supports occupant wellness and your bottom line.
