First of all, I am not sure why people are facing problems with Voltas AC.
I have been using 2 Voltas Split ACs model – Y series classic 185cy 1.5 ton with 5star rating and believe I have never faced any issues till date.
The AC is almost 3 years old and till date it has been performing as expected with very good cooling efficiency. The indoor is very silent, however the outdoor unit is bit noisy but not very noisy, its just the fan sound similar to ceiling fan sound in bedroom.Cooling wise, the AC has been delivering its best without any issues.About the Voltas service, I didn’t face any issue. They visit regularly for routine service and checkup. I am really happy with Voltas.
