Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Trend load percentage against condenser water temperature at the moment of surge.
When to call us
Call us — surge is mechanically destructive and usually fixable with condenser water reset and vane recalibration.
Likely causes
What to check
Measure plant room temperature at the drive intake during peak load.
When to call us
Book a plant room ventilation review — derating shows up as unexplained capacity shortfall on hot days.
Likely causes
What to check
Check return water temperature — CO₂ heat pumps need genuinely cold return water to perform.
When to call us
Call us to review the storage and pipework arrangement rather than replacing the machine.
Parts & Spares
MHI supports Africa through regional distributors and the OEM. Sensors and control components are 3 – 5 weeks; centrifugal internals and inverter assemblies are 8 – 12 weeks, so overhauls need planning well ahead.

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 Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.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