Commercial Stadium Cooling & Heating in Fullerton

Stadium HVAC has to perform under peak heat, fluctuating occupancy, and tight event timelines. As a fourth‑generation family of engineers with 80+ years in engineering, #1 AC Guys delivers commercial stadium cooling and heating in Fullerton that is engineered for comfort, air quality, and reliability—without waste.

Engineered Systems Built for Venues

• VRF and heat‑recovery for suites, clubs, press boxes, and offices—quiet operation, precise temperature control, and energy savings.
• High‑capacity air handling and chiller/boiler plants for bowls and concourses—balanced airflow, humidity control, and durable performance.
• Dedicated Outdoor Air Systems (DOAS) with energy recovery—fresh air at code‑required rates, optimized for IAQ and efficiency.
• Demand‑controlled ventilation—smart CO2 and occupancy strategies so you condition only what you need, when you need it.
• Targeted exhaust and make‑up air for concessions, restrooms, and locker rooms—odor and pathogen reduction with correct pressure relationships.
• Acoustics‑sensitive design—keep crowds loud and equipment quiet with proper isolation, duct design, and vibration control.
• Weather‑resilient, open‑air strategies—sun, wind, and night‑cooling considerations to stabilize fan and field comfort.

Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). We apply manufacturer best practices to complex venues while maintaining brand‑agnostic engineering judgment for your goals and budget.

Healthy Air Is Our Mission

Healthy air for healthy lives is our guiding mission. We design to reduce airborne contaminants and maintain comfort across changing crowds and climates.

• Filtration strategies including MERV 13+ where applicable and serviceable filter banks sized for real pressure drops.
• Humidity management to limit mold risk, protect finishes, and keep athletes comfortable.
• UV‑C and air cleaning options for high‑risk zones and back‑of‑house areas, implemented with safety protocols.
• Pressurization plans that keep fresh air moving in the right direction throughout concourses and restrooms.

Efficiency, Electrification, and Budget Control

We prioritize lifecycle value, not just first cost. Our designs align energy use with occupancy and weather for long‑term savings.

• Right‑sized equipment using load calculations and diversity factors specific to event profiles.
• Heat‑recovery and low‑ambient strategies to move heat where it is needed instead of wasting it.
• Sequencing that stages equipment for partial loads and shoulder seasons.
• Electrification‑ready options and decarbonization pathways that fit your roadmap and utilities.

Smart Controls and Integration

We integrate with your Building Automation System using open protocols like BACnet or Modbus to give operations real control and insight.

• Zone scheduling for game days, practices, concerts, and dark days.
• Trend logging for diagnostics and continuous improvement.
• Sensor placement for CO2, temperature, and humidity that reflects actual occupancy patterns.

Construction That Respects Your Calendar

Downtime is costly. We phase work to keep your venue ready for events.

• Clear submittals, lift plans, and rigging coordination for roof and mezzanine installs.
• Dust, debris, and safety controls to protect the public and staff.
• Commissioning, test/adjust/balance, and turnover training so your operators hit the ground running.

We design and install with industry standards in mind and coordinate closely with the Authority Having Jurisdiction to align with applicable codes and requirements.

Planned Maintenance for Reliability

Peak performance requires steady care. Our maintenance programs are built around your event dates and system priorities.

• Seasonal tune‑ups, cleaning, and predictive checks for critical assets.
• Filter, belt, and coil service timed to occupancy cycles.
• Rapid response for issues that can’t wait until the next game.

Our Process

• Assessment and load study: site walk, existing system review, and data gathering.
• Concept and budgeting: options with clear pros/cons and phased pathways.
• Detailed design: drawings, equipment schedules, and controls sequences.
• Permitting support: documentation aligned with local requirements.
• Build and commissioning: quality installation backed by testing and verification.
• Training and service: operator onboarding and a maintenance plan that fits your team.
