Commercial Stadium Cooling & Heating in Rialto

Engineered for Stadium-Scale Performance

Stadiums and arenas operate unlike any other commercial property: massive air volume, fast occupancy swings, and strict comfort and safety targets. #1 AC Guys brings 80+ years of cumulative engineering expertise across four generations to design and maintain HVAC systems that stand up to these realities. Our engineers are factory-trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), enabling us to apply advanced VRF/VRV, heat pump, and split-system strategies where they fit best—while keeping serviceability front and center.

In Rialto’s Inland climate, we balance cooling capacity, ventilation effectiveness, and energy use with smart zoning, high-efficiency equipment, and controls that anticipate load spikes before kickoff or showtime.

AC PRO Integration for Availability and Uptime

Large venues cannot afford downtime. We specify, source, and support equipment, controls, and parts through AC PRO to streamline lead times and standardize service parts across your campus. That means faster repairs, cohesive warranties, and predictable maintenance—key advantages for stadium operations teams.

From air handlers and condensers to controls, filtration media, and accessories, AC PRO integration helps ensure parts availability on game day and throughout the season.

Design-Build, Retrofits, and Expansions

Whether you are building a new venue in Rialto or modernizing an existing arena, our engineer-led process aligns capacity, distribution, and control logic with real-world usage.

• Load calculations and airflow modeling for seating bowls, suites, concourses, concessions, and locker rooms
• Right-sizing of VRF/heat pump networks, AHUs, DOAS, and economizers
• Zoning strategies for pre-event, live-event, and post-event modes
• Redundancy planning for mission-critical spaces and broadcast rooms
• Commissioning and test/balance to verify metrics on day one

We can phase upgrades to minimize disruption, preserve capital, and capture energy savings early.

Healthy Air Is Our Mission

Healthy air for healthy lives is at the core of #1 AC Guys. For stadiums, that means robust outdoor air delivery, effective filtration, and proven disinfection options that match your risk profile.

• Ventilation aligned with crowd density and local codes
• MERV-13+ filtration, HEPA options for select zones, and UV-C strategies
• CO2 monitoring for demand-controlled ventilation and better IAQ visibility
• Moisture management to reduce odors, corrosion, and mold risk

The result: cleaner air in suites, steady comfort across seating bowls, and better working conditions behind the scenes.

Energy and Controls Built for Events

We design control sequences that shift intelligently between event modes, trimming energy without sacrificing comfort. Integrations include BAS/BMS with BACnet, demand-control ventilation, VFD fan control, supply air reset, and economizer strategies for mild evenings.

Dashboards give facilities teams live insight into zones, alarms, and trends—so you can detect issues before they interrupt the fan experience.

Maintenance That Protects Game-Day Comfort

• Seasonal tune-ups and documented inspections
• Filter plans matched to event schedules and dust loads
• Coil cleaning and airflow verification for peak capacity
• VRF diagnostics, refrigerant health checks, and leak prevention
• Emergency repairs and stocked spares with AC PRO–sourced parts
• Compliance reporting to support safety and insurance requirements

A proactive maintenance plan reduces surprises, extends equipment life, and keeps comfort consistent from first whistle to final encore.

Compliance, Safety, and Noise Control

Our designs follow applicable codes and standards and address stadium-specific safety, including pressurization strategies, smoke control interfaces, and egress considerations. We also plan for acoustics—specifying equipment and isolation methods to keep crowd noise dominant and mechanical noise discreet.
