Ex trimly worst service. If you will call for service, voltas will send some local guys.
They come and start lying like gas is not available in your AC you have to refill, same copper wire will not be used even if it is in good condition in case of re installation.
Very irresponsible and misguide customers to make money. If you call their customer service to complain about all this stuff they will simply deny by saying to go with technicians.
