Commercial Air Chiller Maintenance in Fullerton

Expert Chiller Care From a 4th‑Generation Engineering Family

As a family business in Southern California, #1 AC Guys brings 80+ years of engineering experience to Commercial Air Chiller maintenance in Fullerton. Our mission is simple: healthy air in your building for a healthier life. That means reliable cooling, smart energy use, and maintenance practices that support cleaner indoor air.

Our technicians are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This foundation in manufacturer standards helps us service complex chiller plants with confidence, from rooftop air‑cooled units to integrated systems serving AHUs, fan coils, and ventilation equipment.

What Our Commercial Air Chiller Maintenance Includes

• Operational inspection: verify approach temps, superheat/subcool, condenser fan performance, and control setpoints
• Coil and condenser care: debris removal and cleaning to restore heat transfer and lower head pressure
• Electrical and safety: tighten lugs, check contactors, relays, overloads, sensors, and safeties
• Refrigerant diagnostics: leak screening, charge verification trends, and performance benchmarking
• Vibration and noise: bearings, fan balance, and mounting hardware checks to prevent early failures
• Controls tuning: BAS integration reviews, economizer and reset strategies, alarm logic validation
• Documentation: photo reports, delta‑T trends, recommendations, and capital planning notes

Need more? We coordinate with water treatment vendors when your plant interfaces with hydronic loops, and we align with IAQ targets by reviewing filtration and ventilation strategies tied to your chiller system.
