York screw, scroll and centrifugal chillers serviced across Gauteng.
Overview
York is one of the most widely installed chiller brands in South African commercial buildings — from YCAL and YLAA air-cooled packages on office rooftops to YK centrifugal machines in mall and hospital plant rooms. We service, repair and overhaul the full York range, including OptiView and Micro panel controls.

Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Check chilled-water flow and differential pressure across the evaporator, then compare panel pressure to a gauge reading.
When to call us
If flow is correct and the charge is short, call us — repeated low-pressure trips on a York centrifugal usually mean a leak on the shell or tube sheet.
Likely causes
What to check
Log condenser approach temperature and compare to commissioning data; listen for the characteristic surge cycle.
When to call us
Surging damages the impeller and thrust bearing — shut down and call us the same day.
Likely causes
What to check
Inspect coils for cottonwood and dust build-up, verify all condenser fans are running with the correct rotation.
When to call us
If a coil clean and fan check doesn't stop the cycling, the circuit needs leak detection and a charge check.
Likely causes
What to check
Check differential oil pressure and the filter change log; check crankcase heater operation.
When to call us
Never reset a lube fault repeatedly — call us before the screw rotors are damaged.
Likely causes
What to check
Check control voltage at the panel and look for moisture ingress in the enclosure.
When to call us
Panel spares for older Micro boards are scarce — call us early so we can source or upgrade the controls.
Parts & Spares
York and Johnson Controls parts are well supported in South Africa. Common consumables — filters, sensors, contactors, oil — are typically same-week. Centrifugal wear parts and older Micro panel boards can run 3 – 6 weeks, so we recommend holding critical spares on site for mission-critical plant.

FAQ
A routine York service starts around R4 500 – R9 500 per unit depending on tonnage, compressor count and site access. Repairs are quoted separately after diagnosis. Send us the nameplate photos through the quote form and we come back with a fixed price within 24 hours.
Yes — we source OEM parts through South African distributors wherever the part is still catalogued. Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.
Absolutely. Most of the York plant we look after in Gauteng is well past its warranty period. We service, rebuild and re-commission older units rather than pushing you straight into a replacement.
We work with the unit controller and integrate it with BACnet, Modbus or your existing BMS head-end. That includes alarm mapping, trending, setpoint scheduling and getting fault history off the panel so we can see what actually tripped.
Same-day across Johannesburg, Pretoria, the East Rand, West Rand and the Vaal Triangle. Mpumalanga, North West, Free State and Limpopo are typically next-day, sooner for critical plant.
Yes — quarterly or bi-annual planned maintenance with logged readings, refrigerant records, water-side checks and a written condition report each visit. Contract clients get priority breakdown response.
