Commercial Legionella Prevention for Cooling Towers in Fontana

Mitigating Legionella risk in cooling towers is not a checkbox—it’s an engineered process. In Fontana’s climate, evaporative systems demand disciplined control of temperature, biocide levels, scaling, and biofilm to protect occupants and meet duty-of-care expectations. #1 AC Guys builds prevention programs that are practical for your staff, traceable for auditors, and effective in real-world operation.

What we deliver

• ASHRAE 188–aligned Water Management Programs tailored to your tower, load profile, and seasonality
• Baseline and routine Legionella sampling with accredited laboratory analysis
• Biocide programs (oxidizing/non‑oxidizing) with rotation schedules and verification
• System cleaning and emergency disinfection, including hyperchlorination and post‑flush validation
• Scale/corrosion control, pH and conductivity management, and bleed optimization
• Drift eliminator inspection and upgrades to reduce aerosolized risk
• Sensors and remote monitoring (ORP, conductivity, temperature) with alerts and logs
• Staff training, response playbooks, and compliance-ready documentation
• Integration with Lennox commercial HVAC equipment and building automation to coordinate tower safety with cooling demand

Every site begins with an engineering-grade risk assessment: tower design and condition, makeup water quality, historical data, occupancy sensitivity, and maintenance practices. We then design controls that balance risk reduction, water and energy use, and operational simplicity.

Our step-by-step process

• Discovery and site survey: mechanicals, water treatment, controls, historical incidents
• Sampling plan: locations, frequency, and methods aligned to risk
• Chemical program design: biocides, dispersants, inhibitors, and rotation strategy
• Controls and monitoring: setpoints, alarms, logging, and operator workflows
• Cleaning/disinfection: scheduled and corrective, with chain-of-custody documentation
• Verification and validation: field tests, lab results, and periodic program reviews
• Training: roles, response actions, and reporting templates for audits

Documentation is your safety net. We produce clear SOPs, logs, and test reports so you can demonstrate diligence to internal stakeholders and authorities. Our programs reflect ASHRAE 188 and widely accepted industry guidance used by healthcare, education, and mission-critical facilities.

Why #1 AC Guys for complex commercial systems

We are a fourth‑generation family of engineers with 80+ years in engineering. Our team has completed factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), and we apply the same rigor to cooling tower safety and control. Complex retrofits, mixed equipment fleets, and tight operational windows are where we excel.

• Engineer-led design and commissioning
• Rapid response and clear communication
• Performance metrics tied to risk reduction and uptime
• Transparent pricing and phased roadmaps for upgrades

Lennox HVAC integration

Many Fontana facilities rely on Lennox commercial equipment. We integrate tower safety with Lennox controls and building automation to synchronize load, water treatment, and purge cycles. This coordination helps stabilize temperatures, maintain effective biocide residuals, and reduce conditions that encourage biofilm growth—without compromising comfort or efficiency.

Industries we serve

• Healthcare and senior living
• Education and campuses
• Manufacturing and food processing
• Logistics, warehouses, and data-heavy offices
• Hospitality, retail, and entertainment

Whether you operate a single tower or a multi-building plant, we right-size the plan and provide training so your team can sustain day-to-day controls with confidence.

Service area

Based in Southern California, we serve Fontana and the Greater Los Angeles region, including Los Angeles County and nearby areas such as Orange County, Ventura County, and Western Riverside County. If you manage facilities across multiple sites, we can standardize your program and reporting across all locations.

Getting started

Request a site visit and preliminary risk review. You’ll receive a prioritized action plan—immediate risk mitigations, testing cadence, chemical strategy, monitoring options, and a clear budget. From there, we implement, train, and keep you audit-ready.

Healthy air for a healthy life is our mission—and it starts with safer water in your cooling towers. Let #1 AC Guys protect your people and performance while you focus on running your facility.

• Same‑week assessments available
• Emergency disinfection on demand
• Comprehensive documentation for audits and inspections
