I have been using Hitachi Zunoh 1.5 ton split AC since April 2015. So far I have had to spend around 5000rs for its repair. After installation immediately water leaking started. Hitachi call center number never picks up the call. It is very disappointed. Then the remote stopped working and had to be replaced within one year. Had to pay for it as it is not included in warranty. Then the PCB got damaged and had to be changed. The service technician told me that this model has been very frequent complaints. There is a complete waste of time and money.
