Design-build and retrofit excellence

Starting a new project or replacing aging chillers? We analyze actual load profiles, occupant schedules, weather data, and distribution realities to right-size equipment and pumps. Our retrofits often include VFDs, improved primary/secondary piping, enhanced control sequences, and sensor placement that eliminates false trips and short cycling—lowering kW/ton while improving comfort.

We coordinate permitting and Title 24 documentation, align with water treatment best practices, and commission systems to manufacturer standards for steady-state performance and long-term reliability.

Maintenance that prevents downtime

• Seasonal start-up/shut-down and full operational checks
• Tube cleaning, filter/media changes, and heat-exchanger care
• Setpoint tuning, alarms rationalization, and trend review
• Oil/refrigerant analysis with documented baselines
• Pump, VFD, and valve inspections with corrective actions

Proactive maintenance catches performance drift early, keeping energy costs predictable and equipment life long. You’ll receive clear reporting and practical recommendations—no fluff, just facts.

Smart controls and BAS integration

We optimize control sequences for part-load efficiency, stable supply temperatures, and smooth staging. Our team ensures sensors are calibrated, loops are stable, and alarms are actionable. The result: fewer nuisance calls, better comfort, and measurable energy savings.
