Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Command a capacity change from the panel and watch whether current draw actually follows.
When to call us
Call us if capacity is locked at minimum or maximum — the unit will either short-cycle or waste energy.
Likely causes
What to check
Log source and sink temperatures and flows simultaneously.
When to call us
Book a service — a heat pump that can't reach setpoint is usually a source-side or fouling problem, not a compressor problem.
Likely causes
What to check
Take vibration readings at the bearing housings and trend them.
When to call us
Vibration alarms need attention immediately — call us before a bearing failure takes the impeller with it.
Parts & Spares
Hitachi parts come via Japan and regional distributors. Sensors and controls are 2 – 4 weeks; compressor and centrifugal internals are 6 – 10 weeks. We plan overhauls with parts pre-ordered to avoid extended downtime.

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 Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.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