I am using Voltas split AC 1.5 ton last 3 years and it is extremely good service and cooling with in 10 min.it is genuinely good service that they provide. start with increasing torque and low voltage frequency, however
If you run the air conditioner in turbo mode always, do not expect it to perform as a power efficient product for you.
When it comes to power consumption, as per I said above, they have improved the compressor quality and power efficiency as well with time. However we still cannot compare it with O’General, Carrier or Hitachi since there values differ when compared with Voltas. But when we compared there values with LG, the values of power consumption was less with High rated cooling capacity and product specifications.
