Hi guys, need help here.. Bought mitsubishi starmex single split system non-inverter with crea*** air for my 3rm for my master room. i think i'm misleaded and was given the wrong model by the salesperson intentionally. i realise the model number on my invoice is MS-E10VC (a r22 model which is not stated as starmex in mitsubishi website), i suppose the STARMEX model should be MS-AD10VB, a r410 model. Hence my question is, is MS-E10VC part of the starmex system? cause the website didnt say so. other question is, they claim that aluminium pipe is an upgrade to the copper pipe, so i choose alu. the invoice written is stated as *free upgrade* to alu piping, is this consider upgrade or downgrade? for those looking for single split, my price was $795 + $100 (bracket).
