Chiller service and repair
Diagnostics with measurements and repairs of air-cooled and water-cooled chillers for production plants and buildings. We find the source of the fault before we decide what to replace.
F-gas company certificate. A report with measurements after every visit. Mobile service in Poland and the EU.
When a chiller stops, maintenance departments are often under pressure to do something fast: reset the alarm, add refrigerant, swap a part that looks suspicious. Each of these steps can hide the real cause and make the next failure more expensive. SKiC works the other way round. A technical team arrives with measuring equipment, records the operating parameters, checks the refrigerant and water circuits and the electrics, and only then names the cause and the scope of the repair. You approve the cost before the work starts.
Faults we repair most often
| Symptom on site | What usually stands behind it |
|---|---|
| HP alarm (high pressure) | Fouled condenser, failed condenser fan, overcharge, air in the circuit |
| LP alarm (low pressure) or freezing | Too little water flow, refrigerant loss, sticking expansion valve |
| Compressor does not start | Contactor, motor protection, phase failure, burnt winding |
| Water too warm, unit runs all the time | Lost compressor capacity, fouled evaporator, load larger than design |
| Oil or refrigerant traces on the frame | Leak at a joint, valve, sight glass or vibration-damaged pipe |
| Controller shows sensor errors | Damaged probe, cable, connector or controller input |
Our repair method
- Interview and data. Nameplate, alarm history, when the problem started, what has already been done.
- Measurements under load. Pressures, temperatures, superheat and subcooling, currents on each phase, water flow and temperature difference.
- Root cause. We compare the readings with the design values and identify what is really wrong.
- Quote. Scope, parts and cost, with two or three options where it makes sense (repair, partial modernisation, replacement).
- Repair. Brazing under nitrogen, pressure test, deep vacuum, charging by weight.
- Control measurements and report. The same parameters measured after the repair, recorded in the report.
Compressor replacement
A burnt compressor is a symptom, not the cause. Before a new compressor goes in we check why the old one failed: oil return, liquid flood-back, overheating, electrical supply or short cycling. After the replacement the circuit is cleaned, the filter drier and often the oil are changed, and the unit is tested under load. Skipping these steps is the usual reason why the second compressor fails within a year.
Leak repairs
We search for leaks with electronic detectors and pressure tests with nitrogen. Leaks are repaired by brazing or by replacing the damaged component. After the repair the circuit is evacuated and charged by weight, and the F-gas records are updated.
Brands we work on
Trane, Carrier, Daikin, York, Aermec, Clivet, Climaveneta, Lennox, CIAT, Riedel, MTA, Clint, Hiross, Blue Box, Stulz and others. SKiC is an independent service company, not an authorised partner of any manufacturer, and works after the warranty period.

Questions from maintenance teams
Can you repair a chiller we know nothing about?
Yes. Missing documentation is common. We read the nameplate and the circuit on site and work from measurements.
Do you use original parts?
Original parts where they are available at a reasonable price and time, otherwise proven equivalents. You decide.
What happens to the old refrigerant?
It is recovered with our recovery equipment and handled according to the F-gas rules.
Do you work outside Poland?
Yes. Our mobile teams work in Poland, Germany and other EU countries. Contact us by e-mail.
Chiller failure?
Send the nameplate photo, the alarm code and the location. We will reply with the diagnostic scope and price.
