Ne is using Haier Split AC if tell how is it working i wanna buy haier.
Yes we have Haier splits in office and they are working smooth for the past 3 years. No problem except that one of the unit's gas leaked out and had to be sorted out just a month ago(which is hardly anything out of the ordinary for heavy duty office usage)
Gas should never leak out. And i mean never. if it did then there is a problem. Please make sure you tell the tech to tighten the nuts properly and check for leaks.
Gas leakages are pretty common problems if you live in the Clifton/Defense areas of Karachi.
