Commercial Legionella Prevention for Cooling Towers in Calabasas

Why proactive Legionella control matters

Cooling towers can aerosolize water, allowing bacteria to travel beyond the tower. A proactive Legionella prevention program safeguards occupant health, supports regulatory and insurer expectations, stabilizes system performance, and helps protect your reputation. In Calabasas—where hospitality, offices, retail, and campuses depend on uptime—reliable tower hygiene is a business essential, not a seasonal task.

What our commercial program includes

• Site-specific risk assessment for cooling towers and evaporative condensers
• ASHRAE 188–aligned Water Management Program (WMP) with clear roles, control limits, and corrective actions
• Routine cleaning and disinfection, including mechanical cleaning, descaling, and appropriate oxidizing/non-oxidizing biocides
• Water chemistry control: conductivity, pH, corrosion and scale control, and biofilm mitigation
• Automation and monitoring: controller calibration, sensors, remote alerts, data logging
• Side-stream filtration and solids separation to reduce nutrient load and biofouling
• Verification: culture and rapid test coordination through certified laboratories
• Documentation: inspection-ready logs, trending reports, and audit trails
• Training for onsite personnel on daily checks and escalation steps
• Emergency response and remediation plans for out-of-limit events

We leverage readily available, high-quality materials and components—supported by AC PRO distribution—to shorten lead times and keep your Calabasas facility operating with minimal interruption.

Our 4th‑generation engineering advantage

#1 AC Guys is a family business of engineers spanning four generations with 80+ years of engineering expertise. Our team is trained by manufacturers at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). We apply rigorous, data-driven methods to large and complex commercial systems, bringing the precision of engineering to waterborne pathogen control. Our mission is simple: healthier indoor environments for healthier lives.

Our process

• Discovery: review tower design, occupancy, historical data, and existing procedures
• Onsite survey: inspect basins, fill, drift eliminators, nozzles, fans, and controls
• WMP development: define control measures, monitoring frequency, and corrective actions
• Stabilization: clean, descale, optimize biocide program, set automation and alarms
• Verification: schedule lab sampling and trend KPIs to confirm control
• Continuous improvement: quarterly reviews and adjustments as loads, seasons, or operations change

Technologies and practices we apply

• Biocide strategy: balanced oxidizing and non-oxidizing programs tailored to your water and load
• Biofilm control: targeted dispersants and brushing/cleaning methods for fill and basins
• Scale/corrosion control: inhibitors and setpoint management to protect heat transfer
• Mechanicals: drift eliminator integrity checks, nozzle maintenance, and airflow optimization
• Filtration: side-stream filtration and solids management to reduce nutrients
• Automation: controller tuning, sensor calibration, and remote monitoring for early alerts

Industries we serve in and around Calabasas

• Office parks, corporate campuses, and media/tech facilities
• Retail centers and mixed-use developments
• Hotels, resorts, fitness and wellness centers
