What Adelaide Locals Say
Don't just take our word for it.
"We run a business that has several commercial type airconditioners which had shut down on a 40+ degree day. Jai came out on the same day, found the issue and had them started again within the hour. I highly recommend Jai for any aircon issues you may have."
Nick Dragiotis
Google Review"Jai was very prompt which was great because my air con failed in a heat wave. Luckily, he was able to attend same day and now 24 hrs later I have my new aircon installed and no more heat wave conditions to deal with! Thanks heaps, appreciate it."
Rebecca Williams
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. Outstanding service and knowledge. Will definitely use these guys for future electrical and aircon work."

Josh Montagu
Google Review"Air con in bedroom not working last night - 43 degrees!! Researched a repairer and Voltas was so highly recommended. 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 Voltas highly enough."

Google Review"Jatender has helped me with a number of electrical upgrades to my small unit over the years. He lives locally and has made himself available to do jobs at short notice on a number of occasions. His work is always thorough and well-priced. A pleasure to deal with — no hesitation recommending him."

Google Review"Jai came to look at our electrical switch board. The safety switch was tripping. He found the fault straight away and replaced the safety switches on the switchboard. Will definitely recommend him to our friends and family. He did a fantastic job and fixed the issue on the spot."
Rupesh Chauhan
Google Review"Had the best experience with Jatinder from Voltas Electrical. Our air conditioner had stopped working and we had already got it checked by a few different people, but no one could find the actual issue. Jatinder diagnosed the fault in no time and fixed the problem quickly. Very professional, honest, and reasonably priced. Really appreciate the great service — highly recommend!"

T Bone
Google Review"Jai was unbelievable — called him up on the Saturday of the Australia Day long weekend to get someone to come out as our A/C had stopped completely. He came around on Sunday and went through the whole A/C system to get it sorted..."

Google ReviewFrequently Asked Questions
Answers Adelaide customers ask us most about diagnostic services.
Is diagnostic testing worth it if my system seems to be working fine?
Yes — thermal imaging and circuit testing often catch developing faults in Adelaide properties, like a loose connection overheating, well before they cause a breakdown or safety hazard.
How long does a full diagnostic assessment take?
A standard diagnostic for an Adelaide home typically takes one to two hours, depending on the property's size and the number of circuits or systems being assessed.
What is thermal imaging used for in electrical diagnostics?
Thermal imaging lets us see hot spots in Adelaide switchboards and wiring without touching them, identifying overloaded circuits or loose connections before they cause a fire.
Can you find slow refrigerant leaks?
Yes, we use electronic leak detectors and UV dye to locate even the smallest, most difficult-to-find refrigerant leaks in Adelaide air conditioning systems.
Do I get a report after the diagnostic?
Yes, we provide a detailed diagnostic report for every Adelaide job, outlining our findings, photographs of the issues where relevant, and our recommended solutions.
Do I need a diagnostic before buying a property?
A pre-purchase electrical and AC diagnostic gives you a clear picture of a property's condition before you commit, which can save significant repair costs later.
Can diagnostics identify why my energy bills are high?
Yes, thermal imaging and circuit testing can reveal inefficient circuits, ageing appliances, or an underperforming AC system driving up your Adelaide energy bills.
Is diagnostic testing non-invasive?
Yes, thermal imaging and most circuit testing are non-invasive, meaning we can inspect your switchboard and wiring without needing to open up walls.
Do you diagnose commercial electrical systems too?
Yes, we provide diagnostic testing for commercial properties across Adelaide, including switchboards, three-phase circuits, and refrigeration systems.
