My issue with Gree was that the temperature sensor placed in indoor was sensing too much heat.
It was not faulty but was placed wrongly by the factory. Technician re-positioned the sensor and everything works like a charm now
Amps go down and readings are correct now!
AC service procedure : Your AC is new, don't worry about service before one year at least.
Dont compromise quality for lesser money. Always get those people who have high pressure washer which makes them NOT remove your a.c. You should not let anyone just touch your a.c.
Most people remove indoor and outdoor, that could lead to more gas problems , vacuum issues. It is best to just remove the indoor cover, wash the indoor blower and coil with high pressure water pump PROTECTING the electrical kit. Outdoor cover is also removed and condenser is properly washed with high pressure water while protecting the PCB kit,
Once a year service is necessary for long life of A.C.
