Commercial Chiller Installation in Fullerton — Air‑Cooled & Water‑Cooled

Commercial Chiller Expertise in Fullerton

For Fullerton facilities that rely on dependable, efficient cooling, #1 AC Guys is the trusted local partner. Our 4th‑generation, family‑owned team brings 80+ years of engineering know‑how to air‑cooled and water‑cooled chiller installations, central plant upgrades, and complex retrofits across Orange County. From design through commissioning, we deliver systems that meet today’s energy codes, integrate with your BMS, and reduce lifecycle costs.

Air‑Cooled vs. Water‑Cooled: The Right Fit

Air‑Cooled Chillers are a strong choice for many Fullerton sites—faster to install, fewer site utilities, and lower upfront costs. Ideal for mid‑rise offices, retail, education, and light industrial where roof or grade space is available.
Water‑Cooled Chillers deliver higher efficiencies at larger loads. With cooling towers, variable primary flow, and VFD pumps, they excel in hospitals, laboratories, data rooms, manufacturing, and campuses. Our team will model capacity, part‑load performance (NPLV/IPLV), acoustics, and footprint to guide a confident decision.

Design‑Build Engineering

We provide turnkey design‑build services: load calculations, equipment selection, piping and pump sizing, condenser/tower layout, electrical coordination, and controls architecture. We plan for maintenance access, redundancy (N+1 where required), and future scalability. Our engineers are factory‑trained by Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier—bringing deep understanding of compressor technologies, low‑GWP refrigerants, and advanced controls to your project.

Installation & Commissioning

We manage rigging, structural coordination, seismic anchorage per CBC, piping and insulation, towers and basins, chemical water treatment startup, and TAB (testing, adjusting, and balancing). Comprehensive commissioning verifies sensors, safeties, flows, and sequence of operations—so your plant performs on day one. You receive as‑builts, O&M manuals, and training for your facilities team.

Controls & BMS Integration

Our controls specialists integrate chillers, pumps, towers, and AHUs with your existing BMS via BACnet/Modbus. We program optimized sequences—free cooling where applicable, chilled‑water reset, demand‑limiting, and tower fan VFD logic—to drive efficiency and stabilize temperatures. Remote alarming and trending help you detect issues before they impact operations.

Code Compliance, Permitting & Safety

Your installation is delivered with Title 24 and CalGreen compliance, Fullerton Building & Safety permitting, and SCAQMD considerations. We address electrical clearances, structural requirements, refrigerant safety, and acoustic ordinances. For water‑cooled systems, we coordinate drift eliminators, Legionella risk mitigation, and water treatment protocols in line with industry best practices.

Energy Efficiency & Incentives

We specify high‑efficiency equipment, variable primary flow, EC fans on AHUs, and heat‑recovery options to reduce kWh and kW demand. Our team helps you pursue utility incentives (e.g., Southern California Edison programs, where eligible) and provides ROI and lifecycle cost analyses so you can justify upgrades with confidence.

Healthy Air, Better Workplaces

Our mission is healthier indoor air for healthier lives. We pair your chiller plant with right‑sized coils, MERV‑13+ filtration, UV‑C options, and dehumidification strategies to improve IAQ in offices, healthcare, education, and manufacturing spaces—while maintaining energy efficiency.

Maintenance & Lifecycle Support

Protect your investment with planned maintenance: vibration analysis, oil and refrigerant testing, tube cleaning, tower descaling, and control sequence tuning. Proactive care preserves efficiency, extends asset life, and reduces unplanned downtime. We offer start‑up, warranty support, and ongoing service tailored to your operation.
