The Install That Stops on the Day
It happens more often than it should. The air conditioner is delivered, the installer arrives, and then the job stops because there is nowhere on the switchboard for the circuit it needs.
The cause is nearly always the same. An air conditioner is one of the largest continuous loads in a house and needs its own circuit, but the electrical side gets assumed, not checked while the unit is being chosen.
On an older board that is already full, or one still running fuses rather than breakers, adding that circuit is not a small adjustment. It is a switchboard job first, and finding that out on installation morning is the worst possible time.
- A switchboard with no spare position for a new circuit
- A board still running fuses, not circuit breakers
- An existing circuit that trips when the cooling and kitchen run together
- An installer who needs the electrical work done before they can proceed
- No idea whether the supply to the house can carry another large load

Sorted Before the Unit Arrives
The order that works is simple. Choose the unit, tell us what it is, and let us look at the switchboard before anything is booked in.
We confirm what the unit requires, check what capacity the board has and what the run to the outdoor unit involves, then quote the circuit. If the board needs work first, you find that out with weeks to spare rather than on the morning.
The circuit itself is sized for a load that runs for hours, not minutes, protected correctly and terminated at both ends ready for the installer. We coordinate with whoever is fitting the unit so the two pieces of work line up.
Booked outside summer, all of this is straightforward. Booked in February, everything takes longer, which is the practical argument for sorting it early.

Liam made the whole experience smooth and hassle free. He provided great advice and communicated in a friendly and professional manner. He was accommodating and flexible with my schedule and he left the area clean and tidy. I would definitely recommend him for future jobs.

We were so lucky that some friends recommended Liam. He's friendly, thoughtful, interested in solving problems, in a way that makes him a delight to deal with. We couldn't be happier with the results of his work and unlike other sparkies we've worked with, he turns up on time and even came back on his day off to make sure everything was working as it should. His prices are fair, and his work is of a very high standard. Couldn't be happier. We will definitely be hiring Liam for all future work in our house.

Air Conditioning Circuit Questions
We handle the electrical side: the dedicated circuit, the protection and the connection points. Tell us who is supplying and fitting the unit and we will work in with them so the electrical work is ready when they arrive.
Because of how much current it draws and how long it draws it for. Sharing with a kitchen or laundry means the combined load can exceed what the wiring and breaker were sized for, which shows up as tripping on the hottest days when you least want it.
Send us a photo of the board with the cover on and we can usually tell you a great deal from that. If it has ceramic fuses, no safety switches or no visible spare positions, an upgrade is likely to come first. We confirm properly on site before quoting.
Yes, and it is worth doing. If a switchboard upgrade is happening anyway, adding the cooling circuit at the same time costs far less than returning to do it separately. Tell us what is planned and we will size the board accordingly.
A circuit run on a board with spare capacity is usually a straightforward job. Where the switchboard needs upgrading first, that is a separate day of work, and we schedule the two so the circuit is ready before the unit is installed.
