Can never go wronv with Samsung / Panasonic / Daikin / Mitsubishi

Want cheaper can get Gree

Want cheaper somemore Hisense or Electrolux
I havr Panasonic and Electrolux and Panasonic gives highest problem. Same unit fuse prob twice.
Another Panasonic both indoor outdoor unit cooling coil prob.
Electrolux prob is wiring/piping no issue with itself although this unit not often used.

So i would say many a times aircond prob is caused by external factor such as bad installation of piping or wiring.
Unless u get a lemon unit
