Service guide
Match the electrical supply to the air-conditioning equipment.
A new unit, replacement system and tripping existing circuit need different assessments. The manufacturer requirements, existing wiring and intended installation determine whether a circuit, isolator or protection change is needed.
What our licensed electricians inspect
We review the unit's electrical rating, accessible wiring, local isolation, switchboard protection and available capacity. Fault testing helps distinguish a supply or circuit issue from a fault inside the equipment; a symptom alone does not identify the failed part.
- Indoor and outdoor model details
- Existing circuit and switchboard condition
- Cable route, weather exposure and access
Define the installation boundaries
The quote must identify whether it covers electrical work only or any separately authorised air-conditioning work. Refrigerant pipework, charging, drainage, equipment mounting, removal and commissioning are not automatically included with a new power circuit.
- Confirm the permitted work for the specific system
- Agree responsibility for installation and commissioning
- Check whether larger loads need a supply review
Safe information and handover
Send the suburb, unit model and whether the job is new, replacement or a fault. Safe photos are optional; do not open equipment, climb or enter a roof space to obtain them. Agreed electrical work is tested and explained, without guaranteeing cooling performance or equipment life.
- Tell us about tripping, heat or water damage
- Confirm property permissions and access privately
- Do not keep resetting a repeatedly tripping circuit

Call first
Keep clear of unsafe air-conditioning equipment
Do not keep resetting breakers or touch damaged or wet fittings. For fire, smoke or immediate danger, move to safety and call Triple Zero (000) first. Arrange electrical assessment only after immediate danger is controlled.
The AC circuit or safety switch keeps tripping
Burning smell near the switchboard, isolator or outdoor unit
Heat, buzzing or sparking near the isolator
Outdoor unit power or isolator looks damaged
Water has reached electrical equipment
Power loss, electric shock risk or exposed wiring
Switchboard capacity or protection looks overloaded
Load and capacity
Before adding air conditioning, check the electrical supply
New split systems, heat pumps and larger air-conditioning loads can require a dedicated circuit, isolator, RCBO/safety switch protection, switchboard capacity review or electrical load capacity check. If the supply, switchboard or consumer mains may be undersized, Evaready can review the electrical side before work proceeds.

FAQ
Common questions.
Can an electrician help with air conditioning?
Yes. Evaready Electrical can help with the electrical side of air conditioning, including split-system electrical support, AC isolators, dedicated circuits, outdoor unit power, safety switches, switchboard capacity checks and heat-pump electrical supply.
Do I need an electrician or an air-conditioning technician?
An electrician handles the electrical supply, circuit, isolator, switchboard protection, safety switch behaviour and capacity checks. Air-conditioning installation or refrigeration work is handled by appropriately licensed technicians, so some jobs may need both trades.
What is an AC isolator?
An AC isolator is a local isolation switch near the air-conditioning outdoor unit. It lets power to the unit be isolated for service or safety and must be installed and checked as part of the electrical side of the job.
Does a split system need a dedicated circuit?
Many split-system air conditioners need a dedicated circuit, suitable cable size, an AC isolator and the right safety switch or RCBO protection. The exact requirement depends on the unit, location and existing switchboard capacity.
Why does my aircon trip the safety switch?
An aircon can trip the safety switch because of a fault in the circuit, isolator, outdoor unit supply, damaged wiring, water exposure or connected equipment. If it keeps tripping, do not keep resetting it. Call first so the electrical fault can be triaged.
What photos help with an air-conditioning quote?
Send the suburb, unit model if already known, whether the job is new, replacement, relocation or a fault, and any tripping or water-damage symptoms. Describe access and the proposed electrical work. Photos are optional: use only safe accessible positions with covers and enclosures closed. Do not climb, enter roof spaces, dig, open equipment or approach hazards for a photo. Never delay an emergency call to collect details.
Can Evaready help with heat pump electrical supply?
Yes. Evaready can review the electrical side of heat-pump electrical supply, including circuit requirements, isolators, switchboard protection and capacity checks where relevant.
Can a new aircon need switchboard or load capacity checks?
Yes. New split systems, heat pumps and larger loads can need a switchboard capacity review, dedicated circuit, RCBO or safety switch protection, consumer mains review or electrical load capacity checks before work proceeds.
When should I call first instead of requesting a quote?
For fire, smoke or immediate danger, move to safety and call Triple Zero (000) first. Keep clear of damaged or wet electrical equipment and do not keep resetting a tripping circuit. After immediate danger is controlled, call Evaready about electrical fault assessment. For planned circuit or isolator work, send notes first; safe accessible photos with covers closed are optional.
