This is to bring to your notice the substandard parts used in the manufacturing of Haier room Air conditioners. I had purchased 7 Inverter Air conditioners in February 2020 hardly used them for one season and now two of them are unservicable due to leakage in coil and the third due to circuit board E7 error. Haier technician after checking informs me that in 2 ACs the coil needs to be replaced and it would cost me Rs 32000/- for replacing both ACs coil and Rs 16,000/- for Circuit board. Very very poor substandard Haier ACs. Highly dissapointed. User's recommendation: Check my experience then decide on purchasing Hair ACs.
