Commercial Legionella Prevention (Cooling Towers) in Orange, CA

Why proactive Legionella prevention matters

Cooling towers operate in a warm, nutrient‑rich environment where biofilm can form and harbor Legionella. Mist and drift can spread contaminated droplets, risking occupant health, compliance findings, and costly downtime. A disciplined program reduces that risk, stabilizes water quality, and extends equipment life while protecting your brand.

What our commercial program includes

• Site‑specific risk assessment covering tower design, operation, load profile, and historical water quality
• Water Management Plan aligned with ASHRAE Standard 188, ASHRAE Guideline 12, and CDC best practices
• Cleaning and disinfection services for start‑up, shutdown, commissioning, and corrective actions
• Biocide strategy and automation, including oxidizing and non‑oxidizing biocides, dispersants, and scale control
• Continuous monitoring for residuals, conductivity, pH, temperature, and ORP with alerting
• Side‑stream filtration and basin sweeper upgrades to reduce solids and biofilm formation
• Drift eliminator inspection and upgrades to minimize aerosol carryover
• Startup and seasonal layup procedures, including passivation and safe recommissioning
• Sampling support and coordination with certified labs when testing is part of your plan
• Comprehensive documentation for audits, insurers, and internal stakeholders

Our methods prioritize measurable outcomes: lower biofilm potential, consistent disinfectant residuals, reduced solids loading, and verifiable records that demonstrate control.

Engineered by a fourth‑generation family team

#1 AC Guys is a family‑owned firm of engineers, now in its fourth generation, with 80+ years of engineering expertise applied to HVAC and process cooling. Our commercial technicians are trained at the factories of Fujitsu in Japan, Mitsubishi Electric in Thailand, Midea in China, Gree in China, and Haier in China. We bring that depth to complex, multi‑tower systems serving hospitals, life sciences, datacenters, and high‑rise campuses.

AC PRO–sourced quality components

Reliability starts with the right hardware. Through AC PRO, we source industrial‑grade controllers, valves, sensors, filtration skids, and tower accessories that stand up to continuous duty. That supply strength shortens lead times, supports standardization across sites, and keeps critical spares on hand.

Compliance and documentation

Our programs align with ASHRAE 188 and ASHRAE Guideline 12, and follow CDC and OSHA guidance relevant to cooling towers. We build clear logs and corrective action trails for inspections by owners, insurers, and local authorities. That means fewer surprises during audits and a defensible record of due diligence.

Typical deliverables

• Written Water Management Plan with roles, setpoints, and corrective actions
• Commissioning or corrective disinfection reports with before and after conditions
• Automation setpoints and alarm thresholds with notification tree
• Monthly service reports summarizing readings, trends, and recommendations
• Change‑management log for chemistry, equipment, and seasonal procedures

Our proven process

1. On‑site survey. We inspect towers, basins, fill, drift eliminators, piping, and controls; collect operational data; and review existing protocols.
2. Action plan. We tailor chemistry, automation, filtration, and cleaning schedules to your risk profile and budget.
3. Implementation. We execute cleaning and disinfection, install or calibrate controllers and sensors, and commission side‑stream filtration as needed.
4. Documentation. We deliver a clear Water Management Plan, logs, and reporting templates aligned to ASHRAE 188 and Guideline 12.
5. Ongoing service. Scheduled visits, remote monitoring, and trend reviews keep performance on track and costs predictable.

Coverage and response

We prioritize fast dispatch in the City of Orange and throughout Orange County, with extended coverage across Los Angeles County, Ventura County, and Western Riverside County. Emergency response is available for unplanned outages, water quality upsets, or post‑remediation verification.
