Commercial Chiller Installation in Fullerton (Air‑Cooled & Water‑Cooled)

When uptime, energy cost, and occupant comfort matter, your chiller choice and installation quality make all the difference. In Fullerton and across Orange County, #1 AC Guys delivers commercial chiller projects that balance first cost, efficiency, serviceability, and long‑term reliability—whether you need an air‑cooled unit or a water‑cooled plant with cooling tower support.

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

• Air‑Cooled Chillers: Faster installs, no cooling tower, reduced water use, strong performance in space‑limited or retrofit scenarios.
• Water‑Cooled Chillers: Highest efficiency potential, excellent for large loads and 24/7 operations; requires tower, water treatment, and maintenance planning.

Our engineers model your load profile, ambient conditions in Fullerton, and part‑load behavior to compare life‑cycle costs—not just nameplate efficiency—so you can invest with clarity.

AC PRO‑Specified and Sourced

We install solutions that align with AC PRO specifications and can source equipment and components through AC PRO to streamline logistics, accessory matching, and lead times. This ensures compatibility, code compliance, and clean documentation from submittals to closeout.

Design‑Build Precision

• Right‑sizing using load calculations and trend data
• Equipment selection for acoustics, footprint, and service access
• Hydronic design: primary/secondary, variable flow, delta‑T optimization
• Controls: BAS integration, sequencing, demand limiting, alarms
• Electrical: power distribution, VFDs, soft starters, coordination
• Compliance: Title 24, local permitting, and safety planning

The outcome is a turnkey, code‑ready installation that performs on day one and scales with your operation.

Commissioning That Protects Your Investment

We treat commissioning as a non‑negotiable. Our process includes factory startup (where applicable), sensor calibration, flow and delta‑T verification, BAS point‑to‑point testing, and load simulation. You receive as‑builts, O&M manuals, and a clear maintenance plan so your warranty and performance are protected.

Water‑Cooled Expertise

• Cooling tower selection, placement, and sound mitigation
• Pumps, strainers, expansion tanks, and pressurization
• Water treatment programs that minimize scale and corrosion
• Heat exchanger cleaning access and maintenance corridors

Our team manages rigging, crane picks, and safety logistics to keep your site secure and your schedule intact.

Air‑Cooled Advantages for Fullerton Retrofits

Many Fullerton properties benefit from air‑cooled chillers for speed and simplicity: fewer trades, no tower infrastructure, and excellent part‑load efficiency with modern variable‑speed compressors and fans. We help you prioritize low noise, small footprint, and fast commissioning—ideal for offices, schools, retail, and light industrial.

Industries We Serve

• Office, retail, mixed‑use, and hospitality
• Healthcare and life science suites (non‑OSHPD)
• Education and municipal buildings
• Industrial and warehouse cooling

Whatever the complexity, our engineering‑first approach delivers stable temperatures, humidity control, and cleaner air for healthier spaces.
