"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"We had Jai come out to look at our 2 ducted aircon units that were tripping at the circuit board. Two different companies had told us different things — one said replace it, one blamed the electrics. Jai diagnosed and had both running and serviced within a few hours."
J C

Peter Roberts
Google Review"Outstanding service from start to finish! The air con tech diagnosed and fixed a major issue quickly and efficiently. He explained everything clearly, worked meticulously, and made sure the system was running perfectly before leaving."
Josh Montagu
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. Diagnosed the fault in no time and fixed the problem quickly."
