Commercial Chiller Installation in Rialto, CA — Air-Cooled & Water-Cooled

Why #1 AC Guys for Rialto Chiller Projects

We are a Southern California family business in its fourth generation, with more than 80 years of hands-on HVAC engineering. Our commercial focus means we thrive on large and complex chiller projects. Factory-trained by Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, our engineers bring manufacturer-level discipline to every install and work seamlessly with all leading chiller brands. Our mission is healthier indoor air and dependable comfort, backed by energy-smart design and meticulous commissioning.

Air-Cooled vs. Water-Cooled: What Fits Your Facility

Air-cooled chillers are ideal for faster installs, lower upfront cost, and reduced maintenance. In Rialto’s hot, dry summers, modern air-cooled units with VFD fans and staged compressors deliver strong performance without a cooling tower, making them a great fit where roof or yard space is available and water use must be minimized.

Water-cooled chillers shine on larger loads and where peak efficiency is critical. Paired with a properly sized cooling tower and pumps, they deliver excellent part-load performance and lower sound levels. They’re a smart choice for manufacturing, healthcare, and mixed-use buildings targeting long-term OPEX savings, provided there is water treatment and tower maintenance in place.

Not sure which path to take? We compare lifecycle costs, space and structural needs, water availability, noise targets, and utility incentives to help you choose with confidence.

Our Design-Build Process

1. Assessment and load calculation: We survey existing equipment, process loads, occupancy, and envelope to generate accurate block and diversified loads.
2. Equipment and plant design: Right-size chillers, primary/secondary or variable-primary flow, pump curves, VFDs, and pipe sizing. For water-cooled plants, we design tower selection, basin heaters, and water treatment strategy.
3. Controls integration: Open protocols (BACnet/Modbus), sequence of operations, trending, alarms, and remote monitoring. We integrate with your existing BAS when possible.
4. Permitting and Title 24: Drawings, submittals, and compliance documentation aligned with California energy code and local AHJ requirements.
5. Rigging and installation: Crane plans, seismic anchorage, housekeeping pads, vibration isolation, electrical, and clean piping practices for leak-free, service-friendly layouts.
6. Start-up, TAB, and commissioning: Factory start-up standards, water balancing, setpoint tuning, safeties verification, and owner training, with documented performance benchmarks.

Integration, Controls, and Energy Strategy

We prioritize part-load efficiency with strategies such as variable flow pumping, condenser water reset, free-cooling opportunities, heat recovery for reheat or domestic pre-heat, and demand-response readiness. Our controls team delivers clear graphics, alarms, and trends so your staff can maintain peak performance and air quality day after day.

Industries and Applications We Serve

Office and civic buildings, clinics and healthcare suites, light manufacturing and process cooling, schools and campuses, retail and hospitality, data and telecom rooms, and mid-rise multifamily common-area plants. Whether a rip-and-replace retrofit or a ground-up build, we tailor the plant to your schedule, budget, and resilience goals.

Safety, Compliance, and Quality

Our crews adhere to strict jobsite safety practices, proper lockout/tagout, crane and rigging plans, and seismic bracing per California building requirements. We coordinate closely with inspectors and utility programs to unlock rebates where available. Every installation includes a clean turnover package with O&M manuals, as-builts, and commissioning records.

Service and Maintenance

Protect your investment with planned maintenance: seasonal start-ups and shutdowns, oil and refrigerant analysis, coil cleaning, filter changes, and tower and water chemistry coordination. Proactive care preserves capacity, lowers energy use, and reduces unplanned downtime.
