Commercial Legionella Prevention (Cooling Towers) in Pasadena

Why proactive Legionella prevention matters in Pasadena

Cooling towers can aerosolize water, making proactive Legionella control essential for occupant health, regulatory compliance, and business continuity. Pasadena’s heat waves and seasonal water chemistry shifts increase scale, corrosion, and biofilm pressure—conditions that can elevate Legionella risk and erode system efficiency. A structured, engineering‑driven program keeps risk in check while protecting energy performance and equipment life.

What our commercial program includes

• Risk assessment and baseline sampling coordination with certified third‑party labs
• ASHRAE 188–aligned Water Management Plan (WMP) tailored to your building
• Biocide strategy (oxidizing and non‑oxidizing), biofilm control, and dispersants
• Scale and corrosion control, passivation, and metallurgy‑informed treatment
• Side‑stream filtration, basin sweeper jets, and drift eliminator inspection
• Automated feed and control with calibrated sensors and remote monitoring
• Scheduled tower cleaning, disinfection, and documentation logs
• Startup/shutdown procedures, seasonal commissioning, and emergency response
• Staff training, signage, SOPs, and audit‑ready reporting

Engineering depth you can trust

#1 AC Guys is a fourth‑generation family business with 80+ years in engineering. Our lead technicians and project engineers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We thrive on large, complex commercial projects—hospitals, research labs, universities, hospitality, data centers, and high‑rises—where precision, documentation, and uptime are non‑negotiable.

AC PRO supply advantage

For fast turnarounds in Pasadena, we source quality cooling tower components, controllers, filters, chemicals, and accessories through AC PRO. That means fewer delays, better parts availability, and consistent results when you need service, upgrades, or emergency replacements. We integrate these supplies with your site standards to keep procurement smooth and predictable.

Compliance and best practices

• ASHRAE Standard 188 (Legionellosis Risk Management)
• ASHRAE Guideline 12–2020 (Minimizing the Risk of Legionellosis)
• CDC Legionella Toolkit and industry checklists
• Cal/OSHA expectations for aerosol‑generating equipment
• Los Angeles County Department of Public Health guidance for cooling towers
• Use of EPA‑registered biocides; NSF/ANSI 60–compliant treatment chemicals

While no program can guarantee the absence of Legionella, our approach is built to materially reduce risk, maintain documentation, and enable rapid corrective action if conditions change.

Sectors we serve in Pasadena

• Healthcare and life sciences: hospitals, clinics, pharma, and biotech
• Education: universities, colleges, and K‑12 campuses
• Hospitality and entertainment: hotels, venues, and convention spaces
• Office and mixed‑use high‑rises
• Manufacturing and mission‑critical facilities, including data centers

How we work

• 1) Site visit and data capture: inventory towers, piping, makeup, controls, and historical logs
• 2) Risk review: identify stagnation points, dead legs, temperature bands, and drift paths
• 3) Water Management Plan: ASHRAE 188–aligned WMP with roles, setpoints, and corrective actions
• 4) Implement and automate: biocide feed, corrosion/scale control, filtration, and monitoring
• 5) Validate and document: coordinate lab sampling, maintain logs, and trend data
• 6) Train and support: staff briefings, signage, SOPs, and periodic audits
• 7) Continuous improvement: quarterly reviews and an annual program audit

Technology and reporting

We deploy reliable controllers, conductivity/pH/ORP sensors, real‑time alerts, and cloud logbooks to keep stakeholders informed. You get clear dashboards, inspection photos, cleaning certificates, and exception reports—evidence you can share with internal EHS teams and inspectors.

Service area

Based in Los Angeles, we serve Pasadena and the surrounding region: Los Angeles County and nearby areas including Orange County, Ventura County, and Western Riverside County. Rapid response teams are scheduled to support routine service and urgent remediation.

FAQs

Do you guarantee my tower will be free of Legionella?
No provider can guarantee that. Our program is designed to reduce risk significantly, align with standards, and ensure rapid corrective action when needed.

Do you perform Legionella testing?
We coordinate testing with accredited third‑party laboratories, integrate results into your WMP, and adjust treatment accordingly.

Can you work with our preferred chemicals or BMS?
Yes. We integrate with existing treatment programs and building management systems, or we can design a turnkey solution with AC PRO‑sourced supplies.
