Every AC Electrical Fault, Diagnosed and Fixed

From tripping breakers to burnt isolators and wiring faults. We find the problem and fix it properly.

Tripping Breaker Diagnosis

AC tripping your breaker? We test the circuit, isolator, wiring, and unit connection to find exactly where the fault is.

Isolator Repair & Replacement

Burnt, corroded, or failed isolators are the most common AC electrical fault in Perth. We replace them with compliant units.

Wiring Fault Repair

Damaged, degraded, or rodent-chewed wiring between switchboard and unit. We trace the fault and repair or replace the cable.

No Power Diagnosis

Unit not turning on? We test from switchboard to indoor head to find exactly where the power supply is lost.

Circuit Upgrade

AC on a shared or undersized circuit? We install a properly sized dedicated circuit so it runs without tripping.

Compliance Rectification

Previous install not up to code? We bring the wiring, isolator, and circuit up to current Australian standards.

An air conditioner that keeps tripping is telling you something. The electrical fault will not fix itself - and it often gets worse.

What Our AC Repair Customers Say

★★★★★
"AC died on the hottest day of the year. Response came out same afternoon, found a burnt isolator, replaced it, and we were cool again by dinner. Legends."
- Paul H., Stirling
★★★★★
"Two other electricians could not find the fault. Response traced it to a damaged cable in the roof space. Fixed in an hour. Should have called them first."
- Jenny C., Tuart Hill
★★★★★
"Our ducted system kept tripping. They found the original circuit was undersized and upgraded it to a proper 32A run. No more trips."
- Matt D., Hillarys
Questions Answered

Air Conditioning Repair FAQ

Common causes include a failed isolator, undersized circuit, degraded wiring, a faulty compressor, or water ingress. We test each component systematically to find the exact fault.
If the unit has no power, trips breakers, or has wiring damage, it is electrical - that is us. If it runs but does not cool, that is usually refrigerant - you need a refrigeration mechanic. We can tell you which it is.
It depends on the fault. A simple isolator replacement is quick and affordable. A full cable retrace and replacement takes longer. Call us with the symptoms and we will give you a price.
Yes. We repair the electrical side of all air conditioning types - split systems, ducted, multi-split, and evaporative coolers.
We offer same-day callouts for AC electrical faults, especially 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.
