hi Catz,
so you checked is it higher current allowance. if that is the case as in hdb then you should be allowed only up to 11amps.
next, have you checked whether you are allowed to fix 2 outdoor units at your place? i presume yes as this is determined by hdb.
next would be come the case of how big are these areas.
This i would not be able to let you know as i have no idea what is the square feet or the square meters of the rooms.
for the upstairs i reckon it would be a typical system 3 based on a
12k btu for MBR + 9k but for room 2 and + 9k Btu for room 3.
Though this is subject to change when i have the dimensions of the rooms yeah? so im giving you this quote first
System 3 inverter the easy clean model
MXY-3A28VA (QTY:1 ) this is the outdoor unit (suject to change depending on the dimensions later)
MSXY-GA10VA (QTY:2 ) this is for room 2 and room 3 again subject to changes
MSXY-GA13VA (QTY:1 ) this would be for the MBR
Price is $2,908.50
As for the living and study room boy this is tough. if your living room need as big as 24000btu then im afraid that you would have to also opt for a system 3
reason because for non inverter they are not able to support combinations of say 9k btu + 24 k BTU unlike inverter where it is flexible.
hence if you hall requires more than 12000btu then you would have to opt for a system 3 non inverter with the combination of maybe 9 for study and +9+9 both for living area but it will sorta fall short a bit yeah. so with the dimensions would be great.
im quoting here just in case a system 3 non inverter mitsubishi easy clean model. (the non inverter and non inverter easy clean models look different even though they have the easy clean featyure okie just to let you know first
MUX20TV (QTY:1 ) this is the outdoor unit
MS-A10VD (QTY:3 ) this is the indoor units
$1,953.00
So total would come to about $4861.50
