Engineers First. Always.

Our fourth‑generation team applies 80+ years of engineering know‑how to every decision—load calculations, pump head, condenser water strategies, and control sequences that match your building’s profile. It’s how we deliver quiet operation, steady temperatures, and energy savings you can quantify.

Factory Training That Elevates Quality

We maintain rigorous manufacturer training from Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That foundation informs our approach to Lennox centrifugal chillers—methodical commissioning, clean electrical work, and precision controls—so your plant runs right the first time and every season after.

Tailored to Fontana’s Operations

Fontana’s logistics, manufacturing, and healthcare sites operate long hours under high thermal loads. We design for rapid recovery after door cycles, part‑load efficiency during shoulder seasons, and robust redundancy for critical areas. Whether you’re tightening humidity, stabilizing process cooling, or chasing ENERGY savings, we align the chiller plant with your KPIs.

What You Can Expect

• Clear Scope & Transparent Pricing: No surprises—just detailed plans and accountable delivery.
• Code‑Compliant Work: Documentation, permitting coordination, and best practices throughout.
• Performance Reporting: Baseline metrics, tuned setpoints, and trend logs you can trust.
• Clean Job Sites: Professional crews who respect your operations and schedules.

Maintenance That Prevents Problems

Great chillers fail without great maintenance. Our preventive program includes vibration and oil analysis, tube cleaning, controls verification, condenser water checks, and safety testing. The outcome is predictable capacity, lower kWh, and fewer emergency calls.

Retrofit and Optimization Pathways

If your Lennox centrifugal chiller is reliable but costly to run, we can target high‑ROI upgrades:

• Variable Frequency Drives for compressors and pumps to improve part‑load efficiency.
• Advanced Control Sequences for optimal staging, reset strategies, and demand limiting.
• Hydronic Re‑Balancing to stabilize delta‑T and reduce short cycling.
• Heat Recovery Opportunities where process or domestic hot water can be pre‑heated.

Industries We Support

Distribution centers, food & beverage, healthcare, education, office, retail, and specialized manufacturing. If uptime matters, we design your chiller plant to match.
