Commercial Air Chiller Services in Ontario, CA

End‑to‑End Commercial Air Chiller Services in Ontario, CA

#1 AC Guys provides full‑scope support for commercial air‑cooled chiller systems, from design and equipment selection to installation, start‑up, commissioning, and ongoing maintenance. We serve Ontario, CA and the Greater Los Angeles area, including Los Angeles County and nearby regions such as Orange County, Ventura County, and Western Riverside County.

Our mission is simple: healthy, efficient, and reliable indoor environments. We engineer chilled‑water systems that stabilize comfort, reduce energy waste, and protect your assets—whether you operate offices, logistics hubs, healthcare facilities, schools, hospitality venues, or light manufacturing.

Engineering‑First Approach

With 80+ years of engineering experience across four generations, we approach every chiller project with disciplined methodology:

• Detailed load calculations and distribution design
• Air‑cooled chiller selection optimized for capacity, part‑load, and acoustics
• Hydronic loop design: pumps, valves, and balancing for stable delta‑T
• Controls integration for BAS/BMS with trend logs and alarms
• Title 24‑aligned sequences for energy efficiency and compliance
• Commissioning and performance verification at turnover

Our engineers have trained at manufacturer facilities—Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)—bringing factory‑level rigor to design and start‑up.

AC PRO Equipment, Parts, and Logistics

We work closely with AC PRO for equipment, parts, and project logistics. This helps reduce lead times, simplify replacements, and maintain consistency across your fleet. Whether you need a like‑for‑like chiller swap, a capacity upgrade, or a controls refresh, we specify AC PRO–sourced solutions and coordinate delivery to keep your project on schedule.

• Air‑cooled chillers and matching accessories
• Pumps, valves, controls, and sensors
• Economizers, heat‑recovery options, and IAQ upgrades
• Rapid parts availability for minimized downtime

Industries and Facilities We Serve

• Office parks and corporate campuses
• Warehouses, distribution, and cold storage (air chiller applications)
• Healthcare clinics and medical offices
• Hospitality, retail, and mixed‑use buildings
• Education and public facilities
• Light industrial and technology spaces

From greenfield developments to tight retrofits, we specialize in large and complex work where sequencing, safety, and commissioning determine success.

Our Process

1. Assessment & Strategy. Site survey, load modeling, risk review, and goals (comfort, uptime, efficiency). We align scope, schedule, and budget to your operations.

2. Design & Selection. Right‑sized air‑cooled chillers, hydronic components, and control sequences. We prepare submittals and coordination drawings for a smooth build.

3. Installation & Controls. Safe installation practices, clean piping, proper insulation, and BAS/BMS integration with trend logs, alarms, and dashboards.

4. Commissioning & Verification. Functional testing, setpoint tuning, delta‑T optimization, and documentation so your team can operate with confidence.

5. Training & Turnover. Clear O&M training, maintenance checklists, and spare‑parts plans sourced through AC PRO.

Maintenance, Reliability, and IAQ

Reliability starts with proactive care. Our maintenance programs stabilize performance and help prevent costly failures:

• Scheduled inspections, coil and condenser cleaning, and refrigerant checks
• Pump alignment, vibration checks, belts, filters, and water‑treatment coordination
• Controls calibration, sensor validation, and alarm logic review
• Energy tune‑ups to improve part‑load efficiency and comfort stability

Healthy indoor air is central to our mission. We design for ventilation effectiveness, filtration, and humidity control—because occupant wellness and productivity depend on it.

Retrofits and Upgrades

If your existing air chiller struggles with downtime, noise, or uneven cooling, we can retrofit controls, optimize hydronics, or replace with an AC PRO–sourced, higher‑efficiency unit. Many clients see improved comfort, reduced complaints, and measurable energy savings after commissioning and sequence updates.

Safety, Compliance, and Documentation

We adhere to strict safety practices and build to applicable codes. Our documentation includes submittals, test reports, as‑builts, and O&M materials so your facilities team has everything needed for smooth operations and audits.
