What aircon electrical work covers
Aircon electrical work covers everything between the DB board and the unit: dedicated circuits, isolator switches, cable upgrades, and wiring fault repair. It's the right call when a new install needs power prepared, a breaker keeps tripping when the aircon runs, or an upgrade pushes the existing wiring past its rating. We don't handle whole-house electrical. Common situations where this fits:
New aircon installation needs power prepared
A dedicated circuit, isolator switch, or cable route might be needed before the unit can go up.
Breaker trips when the aircon runs
Cause is usually undersized cable, a loose connection, compressor load, or another aircon-side fault.
Upgrading to a larger system
Existing wiring and breaker rating might not support the new amperage.
When aircon electrical work isn't suitable
We handle aircon-side electrical only. Broader electrical work needs the right licensed trade.
DB board upgrade or replacement
Needs a licensed electrician. Sits outside the aircon installation scope.
Whole-house rewiring or extra power points
General household electrical work is separate specialist work.
Commercial compliance certification
EMA compliance and formal electrical certification need a licensed electrical worker.
What you get
Aircon circuit correctly rated, accessible, and tested before handover.
Correctly rated aircon supply
Cable and breaker matched to the unit load, so undersizing doesn't cause repeat trips or overheating.
Safe isolation point
Outdoor unit can be isolated for servicing without guesswork at the DB board.
Aircon-side scope only
We won't push you into whole-house electrical work when the issue's limited to the aircon circuit.
How an electrical job works
From your first message to a correctly rated circuit, here is what happens.
You message us
Tell us the situation, a new install needing power, a breaker that trips when the aircon runs, or a system upgrade.
We assess the supply
We check the breaker rating, cable, isolator, and whether the fault's the wiring or the unit itself. No quotes over the phone.
We quote the scope
A dedicated circuit, isolator, cable upgrade, or fault repair, priced for what we found. Nothing starts without your approval.
We do the work
We run or upgrade the aircon-side circuit, fit the isolator, and correct any wiring fault, aircon-side only.
We test and hand over
We confirm the circuit's correctly rated and the unit runs without tripping before we leave.
What we check before electrical work
Scope follows the unit load, existing supply, cable route, and whether the issue's the wiring or the aircon unit itself.
Circuit and breaker rating
Existing breaker size, spare capacity, cable rating, and whether a dedicated circuit's needed.
Isolator and access
The outdoor isolation point, safe service access, and whether the switch is in a practical spot.
Cable route
Run length, wall type, trunking path, renovation constraints, and whether a cable upgrade or relocation is needed.
Fault source
Loose connections, damaged insulation, missing earth bonds, undersized cables, and unit-side faults that can trip the breaker.
