Chiller service and diagnostics
Fault finding and repair of air-cooled and water-cooled chillers by an independent, F-gas certified team.
Find the cause, not just the symptom
A chiller that trips on high pressure, does not reach its set point or switches off at night has a reason. Our technicians measure the refrigerant circuit, the water side and the electrics before anything is replaced. You get a clear diagnosis and a quote, not a guess.
- Refrigerant circuit: superheat, subcooling, pressures, leaks
- Compressors: insulation resistance, currents, oil, starts per hour
- Controllers and alarms: Carel, Siemens, Trane, Carrier and others
- Water side: flow, flow switch, pumps, filters, glycol
- Electrics: contactors, inverters, sensors, phase monitoring
Typical problems
What we are usually called for
| Symptom | Common causes | What we check |
|---|---|---|
| High pressure alarm | Dirty condenser, fan faults, overcharge, air in the circuit | Condensing temperature, fans, coil, charge |
| Low pressure or freezing alarm | Low flow, refrigerant shortage, expansion valve fault | Flow, superheat, leaks, valve operation |
| Chiller does not reach set point | Fouled exchangers, lost capacity, wrong control settings | Water temperatures, approach, compressor load |
| Frequent starts or trips | Control settings, sensors, electrical faults | Alarm history, sensors, power supply |
| Flow alarm | Air in the system, clogged filter, pump or flow switch fault | Pump, strainer, flow switch, venting |
FAQ
Chiller service: frequent questions
Which chillers do you service?
Air-cooled and water-cooled chillers from about 5 kW to large screw units, of all major brands, after the warranty period.
Do you carry spare parts?
We keep common parts in our own stock and order specific parts for the unit. Parts are offered as part of the repair, not sold separately.
How long does a diagnostic visit take?
Usually three to six hours on site, depending on the unit and how easy it is to reproduce the fault.
What do we receive after the visit?
A written report with measurements, photos, the diagnosis and a quote for the repair.
