I told you i confirmed with both distributors 
The shop you bought from (hussain chowk and cavalry) are under momin group. MOMIN group is an official distributor of lg in pakistan and uae.
The other distributor of LG is innovi technologies, they also distribute various other Big brands like panasonic etc.
Only these two distributors can import lg official units. OFFICIAL LG warranty in pakistan is by innovi or momin both are serviced by the 0800 number lg care.
When you say official lg warranty it means. When you call the 0800 lg care number they will send their tech and. Honor their warranty. You have that as long as your unit has a warranty card by either innovi or momin.
This unit i could get you for 110k scratchless. When i visited this lg they brought their units from Abid market trust me and it has the same warranty. The place i got it from Is also lg official shop listed on its authorized brand shops. Shouldve pmed me lol.
Wahab seemed sensible but i also asked you to make Him call His Senior if he said korea lol. The ac is assembled in china.
No official installer except daikin or Acson has vacuum.. You need to contact a private installer or buy your own pump like i have.
Btw this lg is awesome i love it. Best cooling ever with best amps. When i was complaining it was because i was using the cool mode and not lgs artificial intelligence mode. The AI mode is Crazzzzzzyyy coooooooool. Im in love with this baby.
