Commercial Chiller Service
Scroll, screw, and centrifugal machines — plus the towers, pumps, and loop that decide whether they actually work.
The Chiller Is Rarely the Whole Problem
A chilled water plant is a system, not a box. When a building runs warm, the chiller takes the blame — but the root cause is just as often a fouled cooling tower, a pump running backwards after a motor swap, air trapped in the loop, a failed differential pressure sensor, or a control sequence that never lets the machine load up.
That is why chiller work starts with the loop. Entering and leaving water temperatures, approach temperature at the condenser and evaporator, delta-T across the coils, tower range and approach, and pump head all get read before anyone opens a compressor.
Getting this right has real money attached. Chilled water plants are typically the single largest electrical load in a commercial building, and a machine running with a fouled condenser burns measurably more energy for the same tonnage — every degree of condenser approach you allow to build costs efficiency continuously, not just on the day it finally trips.
Chiller Plant Services
Air-Cooled Chillers
Scroll and screw machines: compressor service, condenser coil cleaning, fan and VFD work, refrigerant circuit leak repair and charging.
Water-Cooled Chillers
Condenser tube cleaning, approach temperature diagnosis, oil and refrigerant analysis, purge unit service, and eddy-current-driven tube evaluation.
Cooling Towers
Fill replacement, basin and strainer cleaning, drift eliminator repair, fan/gearbox service, and float and makeup water control.
Pumps & Hydronics
Primary/secondary pump service, seal and coupling replacement, VFD tuning, air elimination, and loop balancing.
Water Treatment Coordination
Scale, corrosion, and biological fouling silently destroy tower and condenser performance. We diagnose the symptom and coordinate treatment scope.
Plant Optimization
Chilled water reset, condenser water reset, staging sequence review, and delta-T syndrome correction — usually the cheapest tonnage you will ever buy.
Chiller Plant Diagnostic Sequence
Loop Data First
Entering/leaving chilled water and condenser water temperatures, flow, and differential pressure. Low delta-T across the plant tells a different story than high condenser approach.
Approach Temperatures
Condenser and evaporator approach are the plant’s vital signs. A rising condenser approach on a water-cooled machine points at tube fouling long before the machine faults.
Refrigerant & Oil Condition
Oil analysis and refrigerant sampling identify acid, moisture, and metal wear products — a failing bearing announces itself in the oil months before it seizes.
Controls & Staging Review
Read the plant sequence. Chillers that short-cycle, never unload, or fight each other are usually being told to do so by the control strategy.
Corrective Work & Verification
Repair, then re-run the plant to steady state and re-measure approach, delta-T, and power draw so the improvement is documented rather than asserted.
