wrong.. it does support 24k, just not 10+10+24. it supports 10+24
Not as good , to configuration from system 3 with 24+10+10, can feel the coolest.
All the while my setup maximum on starmex system 3 to go with 10+13+18, if beyond that, would choose single 24k + system 3 or system 4 instead.

how many systems have you installed and used over the years to gather such knowledge? 1? :ROFLMAO:
bottomline is that if it is just $60 for 4H33 vs 3H28, just put the 4H33. it will still have a bit more headroom. you keep saying it is the same, but the specs say otherwise. you refer to the specs as and when it is convenient for you. you either believe it or not.
cherry picking specs to justify is.... sigh...

says you.. have you tested or just assume?
10+10 on both room and after switch on 18k, can feel all the room lower the cooling and become more warm, wait few more minutes later then back to normal cooling.
My old R410A system 3 after 10 years still kick in like normal condition. (Except compressor noise is higher and fan motor noise something loud)
That is why, would prefer maximum setup on 10+13+18 no considered 24+10+10

thats because you didnt upsize and get the 4H38. :ROFLMAO:

but where is the spoiling compressor faster part?
so i assume that you assume it spoils faster.

Why must be follow the salesman told u that getting system 4 instead of 3?
All the aircon configuration's are by personal preference.
the end users happy with pay lower monthly bills can already.

@Jun Jun

hope this help. i use mine as this is the only detail data i have


12k btu = 26c + speed 3 = 12min
18k btu = 26c + auto mode = 4min


12k = 810 watt = 12min = 0.2hr = 0.162kWh = 0.32cent = the amount of power it use to cool down to set temp until operation light is off = $0.05184
18k = 1110watt = 4min = 0.066hr = 0.07326kWh = 0.32 cent = the amount of power it use to cool down to set temp until operation light is off = $0.0234432


watt taken from starmex guide and cool down temp for 12k from me and 18k cool down temp from pete




in short the longer the compressor full load until the operation light is off. the more energy aka $$$$ you pay. so 18k is cheaper. unless the markup is high like my case on the next post to repost/reshare

Sharing my shortlisted these brand and model


Detail:
*Room size of 184Sq ft with data on BTU Calculator 10,792 BTU
*Room is already cooled down with BTU is maintain at 8000
*Temp set at 25c with mid high fan speed
*Electricity cost at 0.3kWh
* 9k and 12k btu add extra 12% and 6% as it take longer to cool room (on average 1hr as compare to 18k btu which need a few min)



18k BTU model
MXY-2H20VF = 15354.6btu = 1664kWh = 52.1% = 866.9kWh = $260.07
CU-2XU20YBZ = 15354.6btu = 1682kWh = 52.1% = 876.3kWh = $262.89

AC cost : MXY-2H20VF (1 FCU) = $2200 , CU-2XU20YBZ (1 FCU) = $2200,


12k BTU model
CU-XU12XKZ = 12624btu = 1472kWh = 63.3% = 931.7kWh = $296.28
CU-PU12WKZ = 11942btu = 1793kWh = 66.9% = 1201kWh = $381.91
MUY-GP13VF = 11942btu = 1548kWh = 66.9% = 1035.6kWh = $329.32

AC cost : CU-XU12XKZ = $1412 , MUY-GP13VF = $1468, CU-PU12WKZ = $1,199



9k BTU model
MUY-GP10VF = 8530btu = 958kWh = 93.7% = 897.6kWh = $301.59
CU-XU9XKZ = 9212btu = 1028kWh = 86% = 884kWh = $300.38
CU-PU9WKZ = 8871btu = 1413kWh = 8871 kWh = 90.18% = 1274kWh = $428.06

AC cost : MUY-GP10VF = $1269 , CU-XU9XKZ = $1309, CU-PU9WKZ = $1,109





This mean 18k model vs 12k model (AC cost is around $750 different) and electricity cost is:

CU-XU12XKZ vs MXY-2H20VF = $36.21per yr = 20yr to break even (excluding inflation)
MUY-GP13VF vs MXY-2H20VF = $69.25per yr = 10yr to break even (excluding inflation)



Comparing 12k btu, 5star vs 3 star:
CU-XU12XKZ vs CU-PU12WKZ = $213 = $84.72 = 3yr to break even

CU-XU12XKZ is more worth it even if have LOT (lot of tech = more point of failure = not as lasting as it 3 star (based on feedback) but the 3 yr electricity cost to even the cost is already worth it

CU-PU12WKZ vs MUY-GP13VF = $52.59 = 6yr to break even the ac cost + electricity cost
MUY-GP13VF vs CU-XU12XKZ = $33.04 = 2.7yr to break even the ac cost + electricity cost

12k btu model: MUY-GP13VF is better then the 3 mode listed as CU-XU12XKZ have a lot more LOT (lot of tech) as compare to MUY-GP13VF



for 9k vs 12k:
9k is just not worth it as it under power, but as this is my back up AC, so i included inside it

CU-PU9WKZ = electricity cost too high at over $100 per yr as compare to other 9k btu model

MUY-GP10VF vs CU-XU9XKZ = $1.20 = 45yr to break even the ac cost + electricity cost

as such MUY-GP10VF is the better choice as it have lesser LOT




9k winner vs 12k winner
MUY-GP10VF vs CU-XU12XKZ = $5.30 = 26yr to break even the ac cost + electricity cost




summary for 2 room type 1 with dual condenser setup :
Main AC : MUY-GP13VF
Secondary AC: CU-XU9XKZ (Diversify )

i never listen to salesman. i follow my own preference. my analogy is the upsizing of fast food meals if the difference is this case is small. ie $60 for daikin 75 to 85. where you really get extra 1.4kw of cooling. isnt this extra cooling help to prevent "killing the compressor lifespan"

for my case system 2 MXY-2H20VF use far less power for it cost me $750 extra (system 1 12k is 1.4k and system 2 is 2.2k (one FCU)) and selecting MUY-GP13VF will cost me extra $70 in my bills per yr but to break even the $750, it take 10yr

i view AC not as lasting as in the old day. so i doubt my ac will be trouble free for 10yr and that another reason why i choose dual system 1 install in different yr

hope it helped @Jun Jun

that is good to hear that 👍
Starmex very different than the daikin, even upgrade from 28 to 33, if turn on 3 room the current input more or less are there , against the BTUs and capacity.
Just starting boosting up from system 4 may highest AMP than the system 3.
Hehe I save a little bit more.

Hi, could I check the 8K BTU after the room is cooled is from where? Interested to know more. Or was it an assumption?

please point me to the right direction

this is to standardize so the 8k, will be apply to all model/brand. so the calculation will be more fair when all use same 8kbtu

alll 8k btu but their power used is still very different. the power cost is taken from NEA

Imagine you get a 2l engine instead of a 1.4 for a big SUV
Ironically the larger engine will last longer and in cruise mode consume less fuel

What i mean is the compressor. Not the indoor. Indoor i no need 18k coz my mbr very small only.

for $60 no need to think so much. get the stronger compressor.

unless u going for dual AC
