Am using mitsubishi starmex. A bit confused after hearing various things.

All along i used fan speed 3 (max is 4) & temp 26 which i find just nice. Then someone mentioned fan speed too low no good cos can cause condensation more easily. Is this true? And is speed 3 considered too slow?

Anyway so i tried turning up to speed 4 but at 26 degrees it was freezing. So i had to increase to 28 degrees. Then some other ppl said aircon not cold enough easy to have condensation! 🙄

Walau like everyone got different theory. So which is true? And which is "better"? Max fan speed (in this case 4) which TBH is quite loud & higher temp eg 27 or 28 degree? Or 2nd highest speed (3) which is less noisy & lower temp eg 25 or 26 degree?

I just want a temp which is just nice for me but not a setting which supposedly causes condensation so easily.

Fan speed low might cause condensation.
Find the best temp setting that you feel the most comfortable with will do.

On my Starmex, I set it to 27 degs with fan speed 2. I supplement it by switching on my ceiling fan which makes it really cold. It is the same logic where you visit a cold country, no wind, no problem. Once the wind blows, I will be taking cover.

lol. when they install the aircon and stuff, did u see the pipes that were laid? what are the pipes and what are they for?

Using the same too, 3 should be fine, 4 will be noisier but good to cool off the room quickly, then u can switch to 3.

You can think of it this way.

Fan speed is how fast you transfer the 'coldness' from the fins to the rest of the room. If the coldness is not transported fast enough to the room, condensation will occur and this will not be good for the FCU.

Best setting is for fan speed to be at the fastest and then adjust ur temperature that u need from there. This will keep ur fins dry and prevent dust from sticking more easily to the fins. With highest fan speed, it also means that u have to clean ur air filter more regularly.

but would this wear the fan motor out faster?

Fan speed too high then it uses higher current and faster for the blower to catch dirt.

Can put to lower fan speed but must do regular cleaning so as to prevent choking of the return pipe.

Regular cleaning is a good practice.

When room temp is way higher then your set temp on the remote, the fan speed will be high.
When temp is achieved or close to your desired temp, the fan speed will be lower.


How about auto fan speed?

How does it work?

Air con fan speed should be fast enough to push the cool air out. No point for the fins being very cold, but is not pushed out fast enough. Condensation is a problem because of this, plus it is not efficient.

Yup. I was told best is use fan speed 5 cos fastest but i find v loud. So was told 4 but nothing slower. And if cold then increase the temp but not lower fan speed. For me 25 degree is just nice & i use fan speed 4.

Guys please help me to clarify on this.

I have always been putting my Aircon starmex system 3 on 26c cool econo cool mode. Fan speed is auto. So this means that when I first on it, the fan will be on high. Then after 5 mins when the room is cooled, it will trottle down to low speed.

Recently I had my Aircon serviced. The guy saw my settings same immediately told me that I should be putting my speed to at least speed 2 or 3. This is because this is to prevent condensation of the pipings and to prevent water leakage.

Is this true? Have I been doing the settings wrong which will damage my Aircon and insulation pipes?

2nd, will putting the fan speed to high cause higher energy consumption? And does this mean that I need to service my Aircon more regularly since the fan speed being higher means the airflow is stronger and that means more dust is trapped in the filters and more water discharged?

Very confused.

would like to know this too as i am using automatic, and it seems not recommended?
I don't want the fan to be on constant level as it will make the room too cold at certain point.
