Fullerton Commercial & Industrial Plant Cooling

Purpose-built cooling for Fullerton’s industrial and commercial facilities

Your plant’s cooling is mission-critical. In Fullerton, CA, we engineer and service industrial-grade HVAC and process cooling that keep throughput high, product quality consistent, and energy and water use under control. As a fourth-generation family business with 80+ years of engineering heritage, #1 AC Guys delivers the reliability, safety, and compliance your operation requires.

Design-build, retrofits, and expansions

From greenfield installations to plant expansions and retrofit projects, our team handles concept-to-commissioning. We model loads, select equipment, and integrate controls to match your production profile and budget. Whether you are upgrading a legacy chiller, adding a new process line, or converting to low-GWP refrigerants, we execute with minimal disruption and maximum ROI.

• Chiller plants: air-cooled and water-cooled, centrifugal, screw, and scroll
• Cooling towers and evaporative condensers with water treatment and side-stream filtration
• Process cooling loops, pumps, VFDs, plate-and-frame heat exchangers
• Industrial ventilation, make-up air, DOAS, and advanced filtration
• VRF and high-efficiency rooftop units for offices, labs, and support spaces
• Cleanroom and lab HVAC, pressurization, and humidity control
• Server room and data cooling: CRAC/CRAH, containment, and redundancy strategies

Controls, monitoring, and energy optimization

We deploy building automation and process controls that make your system transparent and tunable. Expect trend logging, alarm strategies, demand management, and analytics that surface issues before they stop production.

• BAS, PLC, and SCADA integrations with open protocols
• VFD retrofits, sequencing, and optimized setpoints for part-load efficiency
• Title 24 compliance, utility incentives, and demand-response readiness
• Energy dashboards and IIoT sensors for continuous commissioning

Preventive and predictive maintenance

Our maintenance programs focus on uptime, efficiency, and asset life. We combine OEM procedures with predictive tools to reduce unplanned outages and extend equipment lifespan.

• Vibration and oil analysis for rotating equipment
• Tower cleanings, water treatment, scaling and corrosion control
• Tubesheet and condenser cleaning, leak detection, and refrigerant management
• Thermal imaging, electrical inspections, and performance benchmarking
• EPA 608-certified handling and documented compliance

Safety and compliance first

We build every project around safety and local requirements. Crews follow Cal/OSHA protocols, lockout/tagout, fall protection, and confined-space procedures. We account for AQMD considerations, Title 24, and local permits so your plant stays compliant with fewer headaches.

Factory-trained and brand-agnostic expertise

Our engineers are factory-trained by leading manufacturers including Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier. That means better diagnostics, faster repairs, and optimized performance. We service a wide range of industrial and commercial HVAC and process-cooling brands to fit your standardization strategy.
