Commercial Legionella Prevention (Cooling Towers) in Fontana

Why Legionella Prevention Matters in Fontana

Warm weather, variable water quality, and high cooling loads across Fontana and the Inland Empire make cooling towers a critical focus for building health and uptime. Drift, biofilm, scale, and periods of low flow can increase risk if not proactively managed. #1 AC Guys helps you lower risk, document compliance, and protect occupants and operations—without disrupting your business.

Our Process

1) Discovery & site audit: inventory towers, water sources, treatment equipment, and control strategies.
2) Risk scoring: evaluate temperature ranges, stagnation points, drift control, and historical results.
3) WMP build‑out: write and implement procedures, set limits, define monitoring and corrective actions.
4) Upgrades: dosing pumps, controllers, side‑stream filtration, drift eliminators, and sensors as needed.
5) Monitoring & testing: scheduled culture/PCR testing with trend analysis and compliance reporting.
6) Continuous improvement: quarterly reviews, training refreshers, and seasonal startup/shutdown plans.
