yes expensive part s due to invertor.
the service 200rm is from daikin service or ... 200rm to change a pcb i think too much .

ok ..i guess water condense on another part of your unit and this water dont drop in the water tray .

you need to remove the unit cover...
operate the AC till you see water drop ... out .
then visual check where.

its your home so i guess no issues.

i will guess that 90 % of leaks are due to block drainage.
the dust and dirt build up over time and the tubes get block .

Yes, you are right .

Normally the non invertor AC will stop the compressor at about 1-2 deg below your set temp.
so possible the room temp sensor is faulty . but can be other reasons .

what temp do you normally set on your remote ?
your AC is in a enclosed room or hall/open area? ,

yes... if there are a few windows in that room.

2.5 deg difference seems ok bro. getting old so ....

i have a 5 years old daikin
normal have 2 sensors in the IDU

one placed on or near the coil
then other attach on the indoor pcb . some airconds have external means not on pcb. so the sensor is place somewhere near .

Is there any figures for what Savings between the gas ?

so far for gas topup most charge 50rm .

yes all AC IDU must have 2 sensor to detect room temp and coil temp so can control the compressor to shutoff/ turn on.

yes my Daikin room temp sensor is on the pcb .
if you see pix of daikin IDU pcb you will see. google it.

that is why if you check Gree AC , they have a feature iFEEL .
gree put a temp sensor in the REMOTE to sense room temp.

i have same problem ..the blower collect much dust sticking to it. . daikin 6 year old.
cause... intermittent up down air flow pressure..
display fault code A5 on the remote .
later it will shut down the compresser

after cleaning was fine.

i think there is big difference between chinese and taiwan manufacturer .

Hai Hon / Fox is taiwanese .
from what i read the AC designs are Sharp and Fox does the manufacturing .
correct me if i am wrong..

check out Haeir AC s a good budget AC , a good choice if you live around Puchong area , their service center location.
it comes with 3 years warranty for ALL.

other brands can check is Sharp , Hitachi , Gree, Meida depends on your budget.

Try NOT to buy AC s that have low sales . checl lazada you can see sales volume for top sellers.
reason -- spare part will be difficult to find a few year down the road, and Expensive too by then .

check out Mitsubishi spares ..more expensive than others due to smaller sales volume.

yes normal.
but i guess you need a 1.5hp AC . what is your room size ? A lot of big windows ?

assuming lowest temp reach is 24 deg but you set 23 deg ... you will NOT get any/much Power savings.

if you set 23 deg , the AC compressor must work full load to bring the room temp to about 21.5 deg before it can slow down .
it may slow down earlier from comp overheat to protect it.

ok ...
to dimension what size AC hp you need get/buy will depend on your room dimension .

depends on the gas used in the non inverter. if R22 then change.
if piping already more then 5 years ..better change.

AC installation with free 10 feet is about 250 rm average.
some do charge higher .
I did mine at 250 rm this year.

I got feeling that with above AC set up the room cannot reach 21 deg.
and you are using the AC at full load most of the time. hence not much power cost saving.

its good practice have a digital thermometer to measure lowest temperature achieve
only then you can decide on the optimum temp to set on the remote. if you care about power cost . and also a way to verify if you have dimension
the AC hp correct.

for 10 rm you can get digital themo on shopee.
i bought a few and found them good accuracy .

set to 25-26 deg will be nice.

best practice to start AC in dry mode for 1 to 2 hours
then switch to cool mode 25 deg.

above is for power cost savings
if you not worry about power bills then any setting you fancy is fine.

what is the expected lowest temp i should get for this room assuming normal conditions at night , full blast ?
as a guide to dimension the AC .

what is the expected lowest temp i should be looking for assuming with this formula ?
