Initially I was very happy with my Hitachi Logical Mu 1 ton AC but my happiness could not last very long. One fine day I realized that AC cooling is not effective. I called my service guy and realized that gas is leaked. Leakage was repaired and Gas was filled but in next one month Gas again leaked.
Again gas was filled and this time it lasted only for a week. Finally the service guy pointed that AC Coil is weak and suggested me to replace the Coil. I followed his advise and replaced the coil, but even it did not work and gas again leaked.
Since I had paid for new coil recently so I requested to the service guy to repair once again. Once again leakage was repaired and gas was filled but again gas leaked in one week. Finally now I have decided to get rid of this AC.
