"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

"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."

"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."

Frequently 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.
