Called first thing this morning and over the phone was given a solution to try. Did what Jai said and it works. So rare to receive such amazing service. Cannot praise Volta's highly enough. Six stars. Kerry Anderson"
Peter Roberts
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."

I'll definitely be returning to Voltas for any future AC needs."
S Scotland
Google Review"Jatender just installed a split system in a room for us, he was efficient, thoughtful and did an excellent installation which required a bit of creative thinking. His pricing and speed of installation was far better than other quotes and I wouldn't hesitate to use him again. He also gave me some good ideas on how to get more light into the room."

Google ReviewFrequently Asked Questions
Answers Adelaide customers ask us most about new house wiring.
Do you liaise directly with my builder?
Yes, we work directly with your builder or site supervisor on Adelaide builds to coordinate the rough-in and fit-off stages around the rest of the schedule.
Can you wire a granny flat or secondary dwelling?
Absolutely. We handle full electrical fit-outs for granny flats, secondary dwellings, and extensions across Adelaide, including separate metering where required.
At what stage of building do you do the wiring?
On Adelaide builds we do the "rough-in" (running the cables) after the frame is up but before the walls are sheeted, then return for the "fit-off" once painting is finished. For a full breakdown of these stages, switchboard sizing, and compliance steps, see our new house wiring guide for builders.
Can you help design the lighting layout?
Absolutely. We offer electrical design consultations for Adelaide homes to get optimal lighting and powerpoint placement right for how you'll use the space.
Do you install data and TV points?
Yes, modern Adelaide homes need robust networking. We install TV antennas, data points (Cat6), and set up home network hubs alongside the electrical wiring.
Can you wire a home theatre or entertainment room?
Yes, we plan and install dedicated circuits, speaker wiring, and data points for home theatres and entertainment rooms as part of your new build.
Do you install EV charger wiring in new builds?
Yes, we can future-proof your new Adelaide home with dedicated EV charger wiring and circuit capacity, even if you're not installing a charger immediately.
How far in advance should I book for a new build?
We recommend involving us as early as the design stage so wiring, lighting, and data points are planned properly before the first fix begins.
Do you handle the switchboard for a new build?
Yes, we install and connect the main switchboard for new Adelaide homes, sized correctly for your household's current and future power needs.
