Our mission is healthy, efficient air for healthy lives—delivered through disciplined engineering, not guesswork.

What our commercial chiller maintenance includes

• Comprehensive operational assessment: approach temperatures, compressor health, capacity control verification, alarms and safety circuit checks
• Refrigerant management: charge verification, subcool/superheat analysis, leak detection and remediation practices
• Lubrication excellence: oil sampling and analysis, filter replacement, bearing inspection, vibration trending
• Water‑side optimization: condenser/evaporator tube inspection, scaling/fouling review, heat transfer improvements, water treatment coordination
• Electrical and controls: VFD checks, contactors and relays, sensor calibration, BAS setpoint verification, trend review
• Mechanicals: seals, valves, strainers, pumps, alignment, insulation integrity, piping supports
• Coil and hygiene care: coil cleaning, drain pan sanitation, filtration auditing to support healthier indoor air
• Documentation: asset health reporting, energy‑saving recommendations, capital planning insights
• AC PRO sourcing familiarity: service for systems and components obtained via AC PRO distributors; maintenance for AC PRO‑compatible parts

Maintenance plans that fit your facility

We tailor seasonal tune‑ups, quarterly/annual programs, and performance‑based maintenance for office towers, campuses, logistics hubs, healthcare, and industrial sites. Service is scheduled to minimize disruption—off‑hours and weekends available. Our approach blends preventive tasks with predictive insights from oil analysis, vibration data, and BAS trends to prevent unplanned outages.

Engineering depth you can measure

As a fourth‑generation family of engineers with 80+ years in engineering, #1 AC Guys brings uncommon rigor to commercial HVAC. Our teams are factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We apply that training to air‑ and water‑cooled chillers—scroll, screw, and centrifugal—optimizing both process and comfort applications. We also maintain systems sourced through AC PRO distributors and service AC PRO‑compatible equipment without claiming manufacturer affiliation.

Healthy air and compliance, not just cold water

Chiller maintenance affects more than temperatures. Clean heat‑exchange surfaces, proper filtration, and coil sanitation all support better indoor air quality. Our checklists emphasize cleanliness and ventilation verification, helping Ontario businesses align with internal EHS policies and industry best practices while improving comfort and productivity.

Coverage across Ontario and Southern California

We serve Ontario, CA and neighboring areas across Southern California—Los Angeles County, Orange County, Ventura County, and Western Riverside County—backed by fast response from our Los Angeles base. Multi‑site portfolios benefit from standardized reporting and unified maintenance calendars.

Built for large and complex projects

From central plant optimization and load sequencing to hydronic balancing and BAS integration, we thrive on complexity. Our engineers handle retrofit planning, energy conservation measures, and resilience strategies that extend chiller life and cut operating costs.

Results you can expect

• Lower kWh per ton through tuned controls and clean heat transfer surfaces
• Fewer emergency calls via predictive insights
• Extended equipment life and improved reliability
• Clear, actionable reports for facility and finance teams
