Carrier AquaSnap, AquaForce and Evergreen chillers serviced and rebuilt.
Overview
Carrier plant is everywhere in South African commercial cooling — 30XA and 30RB air-cooled machines on retail and office sites, 19XR and 19DV centrifugals in large plant rooms, and 23XRV screw units in industrial process cooling. We handle diagnostics, overhauls and Carrier ComfortLink controls work.

Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Check bus termination and voltage at each board; look for green comms LEDs.
When to call us
If boards are dropping off intermittently, call us — this is usually degraded wiring or a failing board, not a reset issue.
Likely causes
What to check
Compare condenser approach to design; check purge unit run time on low-pressure machines.
When to call us
Rising purge run time means air and moisture are getting in — call us before the oil and refrigerant are contaminated.
Likely causes
What to check
Check superheat against the panel EXV position and the drier temperature split.
When to call us
A drier that is cold to touch on the outlet means restriction — book a service before the compressor is starved.
Likely causes
What to check
Take an oil sample for analysis and log discharge temperature trends.
When to call us
Call us for an oil analysis and vibration check — bearing failure on a 23XRV is an expensive, avoidable repair.
Parts & Spares
Carrier has strong local distribution. Sensors, EXV coils, contactors and ComfortLink boards are usually available within days. 19-series impeller and bearing sets are import items — plan 4 – 8 weeks and let us pre-order for scheduled overhauls.

FAQ
A routine Carrier 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 Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.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 Carrier 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.
