Commercial Cooling Tower Water Treatment in Ontario, CA

Engineered Water Treatment for Ontario Commercial Cooling Towers

When cooling towers struggle with scale, corrosion, or biological fouling, energy costs spike and reliability drops. Our Ontario, CA programs are engineered to protect heat transfer surfaces, extend equipment life, and stabilize cooling capacity through balanced chemistry, precise controls, and consistent maintenance.

We design each program from on-site testing and system audit findings—tower tonnage, metallurgy, cycles of concentration, make-up water profile, load patterns, and environmental factors. Then we deploy a targeted plan that integrates with your building automation and service routines.

What our program includes

• Comprehensive water testing and trend analysis (make-up, recirculating, bleed-off)
• Scale and corrosion inhibition aligned to your metallurgy and cycles
• Oxidizing and non-oxidizing biocide rotation with dispersants to disrupt biofilms
• Startup passivation and seasonal layup/shutdown procedures
• Side-stream filtration and basin cleaning to remove particulates
• Conductivity-based blowdown and automated feed control
• Sensors, controllers, and alarms integrated with your HVAC controls
• Logbooks, service reports, and compliance documentation

Our mission is healthier indoor air through cleaner system operation. Effective tower hygiene reduces aerosolized contaminants, supports HVAC performance, and helps your facility meet internal quality standards.

AC PRO supply readiness

We work seamlessly with trusted suppliers, including AC PRO, to quickly source controllers, valves, filtration media, and compatible chemicals. Local availability shortens downtime and keeps preventive maintenance on schedule, especially during peak cooling season.

Trained experts, complex projects

#1 AC Guys is a fourth-generation family of engineers with 80+ years in engineering. Our technicians are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That foundation lets us align water treatment with HVAC operation on large and complex systems across commercial high-rises, industrial plants, logistics hubs, healthcare, education, and mixed-use properties.

Compliance and risk reduction

Our programs are built to support best practices for Legionella risk reduction and local code requirements. We pair documented biocide programs with cleanings, filtration, and automated controls, then maintain records for audits and internal EHS reporting.

Industries we serve

• Industrial and manufacturing
• Logistics and cold storage
• Healthcare and laboratories
• Office campuses and mixed-use
• Retail centers and hospitality
• Education and public facilities

Our process

• Assess: Site survey, water testing, materials and load review
• Design: Chemistry selection, control strategy, safety plan, KPIs
• Deploy: Install/optimize feed and control, filtration, and monitoring
• Monitor: Routine service, trend analysis, corrective actions
• Optimize: Seasonal adjustments, passivation, and lifecycle planning

We prioritize energy efficiency and reliability: proper cycles of concentration, accurate conductivity control, and consistent biocide/dispersant routines help preserve heat transfer and chiller capacity while managing water and chemical use.
