Why this happens in Western Seaboard
The Western Seaboard combines fast-growing modern housing with the harshest wind and salt conditions in the metro. Units mounted on exposed north-west elevations corrode quickly, and wind-driven rain finds its way into poorly sealed electrical enclosures. Pool heating season runs long here.
We see heat pump refrigerant leak across domestic geyser retrofits, integrated hot water systems, pool plant and commercial installations. The diagnosis is the same discipline every time: prove the fault with readings before replacing anything.
What to do right now
- 01Isolate the unit at the isolator rather than repeatedly resetting the breaker.
- 02Check the airflow path around the unit is clear and look for water beneath it.
- 03Note the brand, approximate age and when the problem started.
- 04Call 069 268 0988 so we can triage before attending.
