Commercial Legionella Prevention for Cooling Towers in Calabasas

Engineering‑Led Legionella Risk Reduction for Cooling Towers

Legionella thrives in warm, nutrient‑rich water. Cooling towers aerosolize water, making disciplined control strategies essential for commercial facilities in Calabasas. #1 AC Guys builds comprehensive, ASHRAE 188–aligned programs that integrate mechanical realities with water treatment best practices—so your tower remains safe, compliant‑ready, and reliable.

Our Structured Program

• Risk Assessment: System mapping, drift pathway review, temperature/flow profiling, dead‑leg and low‑flow identification, and basin hygiene assessment.
• Water Management Program (WMP): Written plan aligned with ASHRAE 188 and CDC guidance—defining control limits, responsibilities, and escalation steps.
• Monitoring & Control: Conductivity/pH/ORP tracking, automated dosing, verification of controllers and sensors, and trend analysis.
• Biocide Strategy: Rotational oxidizing/non‑oxidizing treatments based on load, makeup water quality, and biofilm risk; biodispersants as needed.
• Cleaning & Disinfection: Scheduled tower and basin cleaning, side‑stream filtration support, and documented disinfection procedures.
• Drift & Aerosol Control: Inspection of drift eliminators, air intake distances, and wind‑exposure practices to reduce aerosol spread.
• Corrosion & Scale Management: Chemistry balance to protect fill, basins, and heat‑exchange surfaces while maintaining efficacy of biocides.
• Verification & Documentation: Logbooks, digital reports, and corrective‑action records designed to be inspection‑ready.
• Emergency Response: Rapid remediation plans, hyperchlorination or equivalent methods where appropriate, and post‑event verification.

Why #1 AC Guys

We are a fourth‑generation engineering family with 80+ years of combined experience solving hard mechanical challenges. Our HVAC engineers have factory training with Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). Complex commercial systems are our specialty, and we bring that depth to cooling tower water safety—balancing Legionella risk reduction with energy performance, uptime, and asset protection.

Based in Los Angeles County, we proudly serve Calabasas and nearby communities, including Orange County, Ventura County, and Western Riverside County. Whether you operate a single tower or a multi‑tower campus, we scale our program to your load profile and staffing model.

Documentation and Compliance Alignment

Your Water Management Program is organized around ASHRAE Standard 188 and CDC recommendations, with site‑specific control limits and step‑by‑step corrective actions. We maintain calibration records, dosing logs, cleaning/disinfection documentation, and verification reports designed to streamline internal audits and third‑party reviews.

Seasonal Start‑Up and Shutdown

We prepare and execute seasonal procedures to minimize stagnation risk, biofilm formation, and corrosion during idle periods. Start‑ups include system flushing, inspection of fill and eliminators, controller verification, and re‑establishing control limits before returning to full load.

Emergency Remediation

If a risk trigger is reached or a positive Legionella result is reported by an accredited lab, we deploy an emergency plan—elevated biocide dosing, thorough cleaning, and post‑treatment verification—coordinated with your safety and facilities teams. Our goal is to restore control quickly and document each step for stakeholders.

Clear Next Steps

• On‑site assessment of your Calabasas cooling towers
• Drafting or updating an ASHRAE 188–aligned WMP
• Instrumentation check and baseline sampling coordination
• Program launch with staff training and reporting templates

Our Mission

Healthy indoor environments start with healthy air and safe building systems. Our mission is healthy air at home and at work for a healthier life—delivered through disciplined engineering and transparent service.

Important Notes

We coordinate sampling with independent, accredited laboratories and follow accepted industry guidance. We do not guarantee the complete elimination of Legionella; instead, we implement a risk‑management program to control and reduce the likelihood of proliferation and exposure. Your site’s legal and regulatory obligations may vary; consult your compliance team for requirements specific to your facility.
