Yes. Really.

Last time I am very particular about brands that I only want Mitsubishi or daikin.

Now I find that midea is not bad also actually.

yeah. i also find that midea is not bad... even the price is very competitive... it cools down the place real fast...

For non-inverter aircon, is it normal that the set temperature light will be on for a while and off for a while constantly?

1) buy inverter only
2) make sure the BTU of the aircon is more than enough to cover the area so that it can reach the set temperature in order to save energy. Do consider additional btu if there are more windows and ur house is west facing.

Other than that, that’s all I guess.

Dun go for Panasonic I guess. Personal preference.

can use online BTU calculator to count how much BTU u need for the room to cool. based on the height and width of the space, factor in the amount of windows, whether west facing etc.. to determine the BTU u need. of course this can only be a rough reference... alternatively also can get the aircon man to come and site survey and advise u also.

brand wise, daikin and mitsubishi are always the king of aircons, and i always only trust either of these brands, but recently i come across china brand like midea, also not bad and CP value is good becos the price is cheap. although it is cheap but it works quite well.

higher BTU certainly will consume more electricity...
so if ur room is small, but u use a aircon which is higher Horse Power that exceed the BTU ur room needs, u waste more electricity in long run, but advantage is u can guarantee that ur room can reach the set temperature no prob.

if i am buying i think i will buy ok brand like midea, their inverter is not that ex... but quite good.. fast cooling... durability wise will need to monitor..

samseng stuff always cmi, not surprise... try to buy their tv u will also know...

same 1hp, all non-inverter, the midea aircon in my house can reach the set temperature of 25 degree much much much faster than mitsubishi one..

mitsubishi is really slow in cooling... minimally need 20 minutes and longer to cool down to at least feel some aircon while may not even reach 25 degree..

for midea... less than 5 minutes i can feel almost 25 degree of temperature..

Using cassette aircon at home? Are u sure? 🤪

One thing is that it is more ex, harder for maintenance or more extensive for maintenance, it lower down ur ceiling height (of course for bungalow that the ceiling height is way higher it is not a concern), and if it is having issue like leaking etc. it can cause more troubles than normal wall mount types.

Just my 2 cents.

my rented unit the mitsubishi aircon (non-inverter) was not cold, under defects liability period, in end of dec 2023, fixed one time, they just added the gas, then after 3 to 4 months later later the aircon not cold again, mid of april they fixed it and also added gas, then recently staring early june also aircon totally not cold again (this time was faster)...

they came to fix one week back and now aircon is back to normal... previously it took more than hours also could not hit even 25 degree of temperature set...

now the room after aircon is on the aircon will full blast for 10 minutes, after that it tones down and become quiet air blowing and after 5 more minutes it will hit the 25 degree temperature set..
I supposed this should be 'normal' if an aircon is fully functionally.

now finally the aircon feels normal.. but i hope this will last... becos this was the 3rd time fix as of now..

i told them that it could be due to internal piping inside the wall that is leaking thus even after refilling gas the gas still leaks and if this is not fixed, no matter how many times of refilling the gas, it will still have the same problem.

but the technican who came said, they had done something (which i could not understand fully what they said), but they told me if still have prob they will come again..

hopefully this round the prob is really fixed then no need to fix again.

initially i tot that the master bedroom in the past it took longer time to cool down it was due to the room is bigger than the study room (both are using 1HP aircon, masterbedroom one is using mitsubishi non-inverter given by developer, while study room is using midea who installed by landlord themselves)...

midea aircon is damn cold maybe given the room is smaller, and sometimes daytime when i just set the temperature 26/25 degree i feel too cold that i may need to off the aircon for a while before on back again.

while mitsubishi one i dun feel like that, i feel it is really 25 degree when i really set it to be... and i feel more comfortable with it...

seems like mitsubishi aircon has better accuracy in temperature than midea? even both are non-inverter and 1HP....so my guess is that indeed old and reputable brand like mitsubishi indeed produces better aircon.

indeed... my landlord also never install inverter aircon for my rented unit... so no cost saving for me also since it is not inverter...

Actually for renting a unit, initially I was telling myself that I will only go for the unit that has inverter aircons installed but ultimately I compromise this req because I want to rent the unit.

midea will be even cheaper...

how long does an aircon can cool down to 25 degree is considered 'normal' for its cooling capability?

for room aircon which u are using every night, i highly recommend to use inverter, not only it will save electricity but most importantly, u will feel the constant temperature throughout the night comparing to non-inverter one..
it will be much much much more comfortable for sleeping...

inverter will have the compressor run at lower power to keep the temperature set while non-inverter once reach the set temperature and compressor will stop immediately and once room temperature goes up beyond the set temperature it runs at full speed to reach the set temperature again... and this cycle will continue...
so u can imagine, u will feel the 'change' in temperature inside the room all the time, and ur aircon will be noisy when it runs at full speed for fans...


obviously u did not know aircon by setting ur aircon to 18c.

25/24 degree celcius should be the most comfortable temperature for most ppl to sleep at nite... and it is easier to reach the set temperature given the outdoor temperature at night. 25 degree for my mitsubishi non-inverter aircon it takes about 20 minutes to reach while on at nite... 24 degree will need at least another 10 more minutes.. anything lower than 23 degree will take even longer, and the time taken is not proportional normally... as the set temperature is further away from outdoor current temperature it takes longer to cool down to that set temperature and worst case scenario is that it will never reach becos the set temperature is way too low... typical aircon that has the BTU matches the room size can never hit 18 degree so the compressor will be running at max speed and consumes the max electricity as possible..

so it is totally silly to set the temp at 18 degree...

1 hour just to cool down ur master bedroom??

it means ur aircon BTU is not sufficient for ur room size...

from the speed it cools down, can tell that it is certainly under power for ur aircon to ur room size....

not to mention this is also subjected to other factors such as cold/hot day... whether ur room is having west sun prob etc...

Do u guys really spend money to service ur aircon?

Or u guys just simply clean the filters by yourselves on regular basis but only pay money to get it service when it has prob such as water leaking etc.
