This is very good because this is working is very highly, these machine long life compressor and hard working compressor this machine"s compressor can do- working 24 hours in the day because we are using more split unit and I am service engineer then I can feel how is working. and this machine current combustion( electric unit) is very low. when we do supply current to split ac then take some time for chilling and we will feel early good weather. I suggested that every people -purchase daiken make.
