Troubleshooting Guide
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Trend the condenser approach temperature — a rising approach at steady load almost always means fouling.
When to call us
Once the approach climbs 1–2 °C above commissioning values, book mechanical tube brushing and eddy current testing.
Likely causes
What to check
Measure actual flow and compare entering and leaving water temperatures against the design delta-T.
When to call us
If flow is correct but delta-T is wrong, the refrigerant side needs gauging — call us before efficiency losses stack up on your bill.
Likely causes
What to check
Pull an oil sample annually and review acid number, moisture and wear metals.
When to call us
Any spectrographic red flag means an immediate oil and filter change plus bearing inspection.
Likely causes
What to check
Log purge pump-out counts per day against the manufacturer's allowance.
When to call us
Excessive purging means a live leak. Call for a leak survey before non-condensables damage efficiency and tubes.
FAQ
Quarterly inspections with a full annual service is the standard on commercial plant. Tube brushing is typically annual, and eddy current testing every 3–5 years depending on water quality.
Yes. We service the full loop — tower fill, fans, basins, condenser pumps and chemical dosing — including Legionella risk management and water testing.
Most compressor, motor, starter and tube work is done on site. Where a workshop rebuild is required, we plan the lift, transport and re-commissioning as part of the quote.
A routine annual service is usually 1–2 days per machine. Tube brushing and eddy current work adds a day. We schedule around your shutdown window to avoid downtime.
Often yes — clean tubes, correct charge, optimised condenser water reset and updated controls typically recover a meaningful share of lost kW/TR before any capital spend is needed.
Yes, annual planned maintenance agreements with fixed visit schedules, priority breakdown response and reporting after every visit.
