LG vs Haier vs Midea for Air Con in Colombo

Hi guys, desperately looking for some proper feedback before purchasing my first AC. Looking for something reliable around 200k or under. The Haier and LG ones are preferred but they are from Abans and this sub seems to suggest their after sales is horrible. If I get a private technician to service etc, would the warranty be void? The other two are Midea, which I've hear is good, but the seller is RPG Traders (unheard of by me). If anyone uses one of these units or has any recommendations PLEASE lemme know asap.
