i guess the answer would be it depends on the units EER at specific loads. if you have an inverter which is very efficient at lower loads then you would be best of by using it on lower settings for a longer period. for example i set all my inverter a/c in the house to 28° but i never off them. if you have a regular aircon which only has full load or none then you might be better off running it for the shortest period of time but under _continous_ full load. avoid on/off. i hope this helps a bit.

I believe Panasonic and Mitsubishi inverter type airconds are using conventional piping as well, nope?

Just got my aircon today.

Daikin inverter 1hp ( inclusive of  installation) = RM1300
Daikin Inverter 1.5hp ( Inclusive of installation ) RM1600

i heard daikin air-con quite good ... anyone got experience with it ?

i installed the pana basic model (1HP n 1.5HP)....indoor unit quiet.....outdoor unit quite noisy......i guess my neighbour will cursing me like crazy if i open it overnite....

is pana outdoor unit noisy is considered normal?.....before buy pana a lot ppl said it's quiet (my fault dint go clarify indoor or outdoor quiet).....now feel like kena CON....

Pana sounds unstable lah. My house contractor previously was an air cond service guy. he do not recommend pana but daikin. I browsed through the priced in this forum, daikin is slightly pricier. Is it worth the extra RM100+ for daikin??

hi all

my pana inverter air-cond bought on last year Oct, it had econavi.
now i notice air flow come out only half side of the louver, means just right side got air & no air from left side.

is this econavi fail function? or need a service maintenance?

if a lot dust inside, there should less air flow, but can not be 1 side got air only....really no idea...can any ppl help?

Recently, I am now facing some noise problem (when the vents are set to swing) on 2 of my Pana AC. Reported the problem to Pana and they got their agent and also sent their own technician to look at them. 3 times already. Even after changing the controller board plus the discharge grille. The noise come back after a day or two. 

Damn...Called up ESH to arrange deliver the 4 Units of aircon and been informed the 2HP didn't have stock and only available next month (no confirm date)
It means if deliever after than I will have to re-clean my house / painting (if) and call the aircon folk again ? ...
How come they dont keep stock once customer pay full? Or I should not pay full at all?

Puchong ESH....

Weikee
I purchased during the roadshow and indicated will get from them around Dec...

Now I either Wait / Cancel it (but I have pay full), downgrade from 2HP to 1.5HP and get something for rest of balance...

has anyone use those 3M Filtrete as an added filter for their split aircons?
my worries are -

1. does it impedes airflow and drop the efficiency of your aircon?
2. will it keep the blower fan blades clean as this is the part where it gets really dirty
3. how often do you need to replace it based on past experience

Haven't had my Daikins breakdown on me yet... these days Daikins are all export quality as they are sourced from Thailand so I seriously doubt their build quality can be worse than locally assembled Yorks or Panasonics. I know some aircond installers grumble because the compressors are freaking huge. Also the wiring is different from other air conds and in theory should be less prone to the PCB frying compared to York. Another reason some air cond installers may not like Daikin is that usually these are serviced directly by their own technicians so less chance for outsiders to cari makan from them....
So far in use I find they are extremely quiet so no complaints so far. However if you are the super impatient type who wants the aircond to blast cold air at you the moment you switch it on, please don't get Daikins: Daikins take their own sweet time to power up.

The start up is a bit slow because there's a built in logic to move the louvres up and down to drain out any potential condensation before powering up the blower. Noticed this on both their inverter and non-inverter models. As you say, even their compressors are really quiet..

That why got better technology why not to try.. Use more and save more electric bill with reduce noise at night time.
Cause due to outdoor fan speed is follow actual temperature to reduce high & low & even compressor speed.

Mine is Mitsubishi electric starmex so far so good, already has been usage 3 yrs long still quiet at all.

Never ask aircond service for repair a once.
Cause I know how to solve on water leakage & use filter to block more dust at all.
