Troubleshooting Guide
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Compare return water temperature and superheat against the design envelope before touching the charge.
When to call us
Repeated discharge trips cook the oil and the compressor — call before the next restart.
Likely causes
What to check
Measure pressure drop and temperature approach across the heat exchanger and compare to commissioning data.
When to call us
Rising approach or pressure drop means a chemical descale is due — we do CIP descaling on site.
Likely causes
What to check
Confirm the crankcase heater is warm before start and check the oil level in the sight glass at start-up.
When to call us
Foaming oil at start-up means liquid slugging risk — call before bearing damage occurs.
Likely causes
What to check
Observe a full defrost cycle and confirm the reversing valve actually shifts and the coil clears fully.
When to call us
Ice building up cycle after cycle needs valve and control diagnosis before capacity collapses.
FAQ
Twice yearly for hot water plant and quarterly for process duty. Ammonia and CO₂ systems have additional statutory inspection and leak-detection requirements we handle for you.
Depending on refrigerant and cascade design, 65–90 °C is routine and specialised machines go higher. We size to your actual process temperature and flow.
Yes, including leak detection, high-side pressure and PRV service, cascade tuning and compliance documentation.
Often partially or fully, depending on required temperature and available heat source. We assess your load profile and give a realistic running-cost comparison before recommending anything.
Yes — heat pump, tank, circulation and controls, including Legionella-safe temperature management and after-hours support for guest-facing plant.
Same-day attendance across Gauteng and next-day in surrounding provinces, with common spares such as sensors, valves and contactors carried on the vehicle.
