I also plan like this. Living & Dining share 1 aircond need ask contractor also. I just check have branch nearby my house but the price don't know can get or not. BTW do you have ask price for 2HP inverter too?
living room and dining room and dry kitchen is linked up together,
so that's the problem here, so need 2.5HP at least.
I probably might install one aircon at dry kitchen later on depends on the usage in future.
Wet kitchen then is separated by a sliding door.
Personally I just need to cool down the temperature, don't need to be like in Alaska, so 2.5HP probably is enough.
I already ask main contractor to install the inverter pipe for 2.5HP link from living hall and the compressor i am going to keep at 20 feets away from the living hall (wall beside the master bed room).
if your house is too far from the branch here, I guess RM50+ is quite OK, they probably charge u the same for transportation too.
