Every Electrical Fault, Diagnosed and Fixed

From tripping breakers to burnt wiring and failed isolators. We find the fault and fix it properly.

Tripping Breaker Diagnosis

If your split system trips the breaker every time it starts, there is an electrical fault. We test the circuit, isolator, and unit wiring to find it.

Isolator Replacement

Failed or burnt isolators are one of the most common split system faults in Perth. We replace them with compliant double-pole units.

Wiring Fault Repair

Rodent damage, corrosion, and age degrade wiring over time. We trace the fault, repair or replace the cable, and retest the circuit.

No Power to Unit

Indoor or outdoor unit not receiving power? We test from switchboard to unit to find exactly where the supply is lost.

Circuit Upgrade

Older homes often have split systems on shared circuits. We install a dedicated circuit so the unit runs reliably without tripping.

Compliance Rectification

Non-compliant wiring from a previous install? We bring it up to current Australian standards and issue a certificate.

Is your split system tripping the breaker or refusing to start? That is an electrical fault - and it will not fix itself.

Questions Answered

Split System Repair FAQ

The most common causes are a failed isolator, degraded wiring, a faulty compressor drawing too much current, or a shared circuit that cannot handle the load. We test each component to find the exact cause.
If the issue is electrical - no power to the unit, tripped breaker, blown fuse, wiring fault - yes. If the issue is refrigerant or mechanical, you need a refrigeration mechanic. We can tell you which it is.
It depends on the fault. A simple isolator replacement is straightforward. A full wiring trace and repair takes longer. Call us with the symptoms and we will give you a diagnosis clear plan from your first call.
Most electrical faults can be repaired without replacing the unit. Failed isolators, tripped breakers, and wiring faults are all fixable. We will tell you honestly if repair or replacement makes more sense.
We offer same-day callouts for AC electrical faults during summer. Call us and we will get you booked in as fast as possible.
Yes. Every electrical repair we complete is tested and a certificate of compliance is issued. This protects you and keeps your insurance valid.
