I have been using Mitsubishi since 9 years and it has been working efficiently since then , only regular services done, no parts changed.Cooling efficiency is unmatched and heavy copper compressor does the work very well.It will be one your best investment and be tension free.Mitsubishi has mastered the art of technology and don't compromise with hardware too.
The umatched quality standards which mistubishi relies on leads to its efficency and long life.
