Commercial Legionella Prevention (Cooling Towers) in Downey

Why Legionella Prevention Matters in Downey

Cooling towers can aerosolize water and, without strict control, become a reservoir for Legionella bacteria. For commercial properties in Downey, proactive prevention minimizes health risks, regulatory exposure, and downtime—protecting patient safety, guest confidence, and business continuity.

Our programs align with ASHRAE 188 and CDC guidance, and follow Los Angeles County public health recommendations. We emphasize documentation, verification, and rapid response so your team can demonstrate due diligence at any time.

Engineering‑First Approach from a 4th‑Generation Family Team

#1 AC Guys is a family business now in its 4th generation of engineers, with 80+ years of engineering experience. We are trained at manufacturer facilities including Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That deep technical background helps us solve complex cooling tower challenges—from hydraulic issues and drift control to precision dosing and automated oversight.

Comprehensive Legionella Risk Management for Cooling Towers

• Risk Assessment: System mapping, exposure points, occupancy risk, seasonal loads, and water chemistry baselines.
• Water Management Plan: Roles, responsibilities, setpoints, corrective actions, and verification protocols aligned with ASHRAE 188.
• Treatment Program: Oxidizing/non‑oxidizing biocides, biodispersants, corrosion/scale inhibition, and automated feed control.
• Monitoring & Testing: Conductivity, ORP, pH, dip slides, ATP screening, and culture testing per accepted methods.
• Cleaning & Disinfection: Scheduled tower cleanings, emergency shock disinfection, and post‑service verification.
• Upgrades: Side‑stream filtration, drift eliminators, basin sweeping, smart controllers, and remote alarms.

AC PRO Supply Advantage

We leverage AC PRO’s professional supply network for rapid access to tower components, controllers, filtration, valves, and treatment accessories—reducing lead times and keeping your Downey facility on schedule.

Documentation That Stands Up to Review

• Written Water Management Plan with site‑specific procedures.
• Service reports, test logs, and chemical inventory records.
• Corrective action documentation and validation steps.
• Owner training and quick‑reference response checklists.

Clear documentation helps demonstrate compliance during audits, insurance reviews, or health inspections.

Upgrades that Reduce Risk and Improve Efficiency

• Side‑Stream Filtration: Reduces suspended solids that shelter bacteria and foul heat exchange surfaces.
• High‑Efficiency Drift Eliminators: Lowers aerosol emission potential; a key control layer for Legionella risk.
• Automated Dosing & Monitoring: Stable biocide residuals, alarms, and trend data for faster corrections.
• Basin Sweeping & Sludge Removal: Minimizes biofilm formation and nutrient load.

These measures not only reduce bacterial risk but can also improve thermal performance and water/chemical efficiency.

What to Expect When You Work with #1 AC Guys

• On‑Site Assessment: We document assets, loads, piping, and controls; gather water chemistry; and identify risk points.
• Custom Plan: We deliver a tailored Water Management Plan and maintenance schedule your team can execute.
• Implementation: Chemical feed setup, controller programming, hardware upgrades, and staff orientation.
• Routine Service: Scheduled testing, tower cleanings, and performance reviews with continuous optimization.
• Emergency Response: 24/7 availability for disinfection and corrective actions after alarms or test results.

Testing and Verification Protocols

We use a staged approach: frequent indicator checks (conductivity, ORP), routine microbiological screening, and periodic culture testing as directed by your plan. Verification confirms that controls are working; validation demonstrates the program is achieving expected outcomes.

Safety, Compliance, and Practicality

Our procedures are built to align with ASHRAE 188 and CDC recommendations while remaining practical for on‑site teams. We emphasize hazard communication, chemical handling safety, lockout/tagout during cleanings, and clear escalation steps when thresholds are exceeded.

Transparent Pricing and Ongoing Support

We provide clear scopes, predictable maintenance pricing, and options for upgrades that deliver measurable risk reduction. Remote support and alarms help us intervene before minor deviations become major issues.
We stand behind our work, but no program can guarantee total elimination of bacteria. Our commitment is to implement and maintain a defensible, data‑driven plan that materially reduces risk and supports compliance.
