Commercial Air Chiller Services in Fullerton — AC PRO Solutions by #1 AC Guys

As Fullerton’s commercial air chiller specialists, #1 AC Guys combines deep engineering with practical field execution to deliver cooling systems that run cleaner, leaner, and longer. Whether you need a ground‑up design, an AC PRO air‑cooled chiller upgrade, or a rapid repair before production halts, our focus is measurable performance and healthy indoor air.

What we service and install

• Air‑cooled chillers (scroll, screw) from 10–500 tons
• AC PRO air chiller equipment, coils, pumps, VFDs, and hydronic accessories
• Primary/secondary pumping, variable flow, and loop optimization
• Building automation and BMS integration, alarms, and remote visibility
• Heat exchangers, cooling coils, and energy recovery components
• Water treatment guidance for scale, corrosion, and biological control

Our mission is healthy indoor air for a healthy life—at scale for commercial spaces. That means clean coils, proper filtration, balanced airflow, correct refrigerant charge, and controls that prevent short‑cycling and humidity swings. The result: stable comfort, better IAQ, and lower energy spend.

Design-build and retrofit excellence

We right‑size systems based on real load profiles, not rules of thumb. Our designs consider envelope, occupancy, process loads, schedules, and climate patterns in Fullerton and Orange County. Expect thoughtful equipment selection, piping schematics, controls sequences, and commissioning plans that stand up to peer review.

• Lifecycle and total cost analysis (not just first cost)
• Redundancy planning to protect critical operations
• VFD strategies for pumps and condenser fans
• Sound, footprint, and service‑clearance constraints
• Title 24, ASHRAE, AQMD, and OSHA considerations

We frequently deliver AC PRO air chiller upgrades that reduce kWh while improving capacity control—often unlocking utility incentives. Our commissioning verifies kW/ton, supply/return deltas, flow balance, and controls setpoints with documented results.

Maintenance that prevents downtime

Unplanned outages are expensive. Our preventive plans catch issues before they escalate and maintain healthy indoor conditions for staff and guests.

• Seasonal startup/shutdown and full functional checks
• Electrical inspections, vibration and bearing analysis
• Condenser coil cleaning and microchannel care
• Refrigerant diagnostics and leak detection
• Flow, pressure, and temperature trending for early warnings
• Water treatment coordination to protect heat transfer surfaces

You’ll receive clear service reports with prioritized recommendations and budget options. Need urgency? We offer rapid dispatch across Fullerton and surrounding Orange County.

Controls and BMS integration

We program sequences that match your building’s true needs: optimized setpoints, economizer logic, pump staging, and demand response. Integration with your BMS unlocks alarms, trending, and remote diagnostics—turning data into uptime.

Factory-trained craftsmanship

Our engineers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That manufacturer‑grade mindset guides our fieldwork—tight brazing, proper evacuation, precise charging, and data‑driven commissioning—on every commercial chiller we service or install, including AC PRO air chiller solutions.
