Google Review"Jai came to fix my aircon when other people said that the unit needs replacing. He fixed it on the same day Highly recommended him to my friends and definitely use him in the future."
Tekiesha Bell
Google Review"We had Jai come out to look at our 2 ducted aircon units that were tripping at the circuit board. Previously we had 2 different companies come out, one suggested to replace the whole unit and the other didn't believe there was an issue with the unit and suggested it was probably an electrical fault that needed an electrician. We were unsure what was right so thought we would give Voltas a try. Jai arrived within about an hour and a half, diagnosed the issues with parts in both units and had them up and running and serviced within a few hours, this also included a run for some spare parts. Outstanding service and knowledge. He gave us a good run down of the problem, some future options and sorted out a couple of other minor issues after discussing them with me. Will definitely use these guys for future electrical and aircon work."

Google ReviewFrequently Asked Questions
Answers Adelaide customers ask us most about residential & commercial electrical upgrades.
Will I lose power during a switchboard upgrade?
Yes, power is switched off for the duration of the upgrade — usually a few hours. We schedule this at a convenient time for your Adelaide household and let you know exactly what to expect.
How do I know if my switchboard needs upgrading?
Warning signs include visible ceramic fuses, a switchboard over 25 years old, frequent trips, or a burning smell. An obligation-free on-site assessment of your Adelaide property will confirm what's needed — see our guide on how often to get a full electrical safety inspection if you're not sure when your property was last checked.
Why do I need to upgrade my old ceramic fuses?
Ceramic fuses do not provide the fast-acting protection against electric shock that modern Safety Switches (RCDs) do. Upgrading is crucial for the safety of your family. See our guide on circuit breakers, fuses and RCDs explained for exactly what each device does and how to tell which one your board has.
How do I know if I need a three-phase power upgrade?
If you're installing a large ducted air conditioning system, high-end electric cooking appliances, or heavy workshop machinery in Adelaide, you'll likely need three-phase power.
How long does a switchboard upgrade take?
A standard switchboard upgrade for an Adelaide home usually takes between 4 to 6 hours, during which the power will be turned off.
Will upgrading my switchboard reduce my insurance premiums?
Some insurers offer better terms for homes with modern safety switches installed, so it's worth checking with your provider after an upgrade.
Can you upgrade my switchboard without a full rewire?
Yes, in most Adelaide homes we can upgrade the switchboard on its own without touching the existing wiring, unless an inspection finds a separate issue. If you're weighing up a standalone switchboard upgrade against bundling it into a full rewire, our electrical rewiring cost guide breaks down real Adelaide pricing for both.
Do I need a bigger switchboard for solar panels or a battery?
Often yes. Solar and battery systems typically need additional switching and metering capacity, which we can assess and include in your upgrade.
What happens to my old switchboard?
We safely disconnect and dispose of the old switchboard and fuses as part of the upgrade, leaving your property tidy.
