Hi sifus, now i am using 6 ME inverter airconds in my house. May i know how to clean the aircond ourselves? Thanks!

York didn't change name to Daikin.

Group Associated used to be the company selling York in Malaysia since the beginning, until recently (like 2~3 years back). They obtained the rights to Daikin in Malaysia, and have since dropped York and started selling Daikin. The early Daikin models sold by GA were actually York air cons with Daikin brand on it.

Now York is back in Malaysia, but made in China and not by GA.

So if you want "York" of yesteryear, buy Daikin.

Finally got the installer to check, turns out probably my unit is a melon.

It works great, except when it slows down, there's this eeeek eeek sound which turns out to the the outdoor unit's internal components rumbling. Oddly, when the installer pressed on the outdoor unit cover, the squeeking noise went away. When he released his hand, the squeeking noise came back.
LOL.

So can't do anything about it :/

too bad, i should have done it, but didn't. Didn't realize that, but since at the moment everything is okay, so i don't want to fix what isn't exactly broken.

My 8 year old 1.5hp Panasonic inverter coils have frozen up and blocked and was quoted around rm 1150 to get everything fix.
But my family wants a brand new aircond instead of repair.

We already have a Mitsubishi 1.5hp and 2 Panasonic 1.5hp deluxe models and 1 Panasonic 1.5hp basic model. 

Since we tend to prefer our room very cold instead of just cool, which air conditioner would be best for the job?
I believe many deluxe models advertised as saving electricity affects the coldness performance by aiming for coolness instead.

I am not interested in automatic features anymore. I just want plain cold air as we are sports oriented family and so we need cold not just cool air

What about 2hp - Daikin or York or Panasonic. 

Which aircond is best to produce really cold air? 

Hi Sifu's

Was thinking of the option of multi split type since i kinda have a space issue and heat that is generated from having 2 compressors running at the same time.

Wanted to know is it truely a good option to work with? besides the fact that if there is an issue with the compressor then 2 rooms will have a problem instead of one, is there anything else to know about this type of aircon?

its just the vibration sound, so i'm not too bothered.

How much is the maximum copper pipe length can use from indoor unit to outer unit for 2 H.P ? It will effect the cooling performance of the A/C ?

If i on the aircon, it trip the electrical circuit breaker.
But now, no trip... once a while i heard a spark sound like breaking a pen sound.
what is the possible problem?

thats what i think of
Now not using the aircon anymore.

This is due to improper installation by the technician who are not professional on installing it.

Yes, i admit that practice to switch off main switch just for the sake of electricity saving! I recalled sometimes when switch on the light, e27 energy saving bulb just suddenly burnt ! So inverter's PCB could be just died in that way...  Normally, what is the wattage for standby power of aircond ?

How about non-inverter ? Also need in standby mode ?

Finally got my Urusara 7 installed. So many function have no time to try it yet.
First impression is it is HUGE! Definitely not a beauty.
The cooling wise it is doing very well as expected. I'm setting my room temp to 26degC, with the inteligent eye function, the AC is able to sense my location and send the cold air to me, which is quite funny.
The rest yet to be discover.

damn...look at the energy commission sticker label. it has 785 kwh/year rating. meanwhile my cheapo Pana Inverter shows 1492 kwh/year. it is indeed the best inverter ever. Non inverter normally shows more than 2000 kwh/year

setting lower temp like 16C will surely increase the consumption. 785 kwh/year is the ST label for the Urusara 7. if you check carefully the nominal power consumption is about 430W, current rating is about 2 amp++, Pana Inverter about 760W with 3.3-3.6 Amp

no that is Daikin Urusara 7 1.0 HP using new standard of gas (R32). cost about RM 5k. yes power rating in the spec about 430W with current consumption about 2.0 Amp. that is almost close to 50% reduction of power consumption compare to the Pana Inverter 1.0HP (RM 1.3-1.4k)

don't forget the EER, BTU/w. normally inverter has more and better EER which translate to a better cooling rate at better power consumption

BMW 328I long time ago was using 2,800CC engine and produce around 240hp.
The new generation 328i is using 2,000CC engine to produce around 240hp.
The name it with the end results regardless of it's engine capacity.

Same concept with AC, all AC with Btuh of around 8,000 t0 10,000 are classified as 1hp.
Actually Urusara 7 max power is around 880W (producing 13,300 Btuh) can we called it 1.17 hp? So Urusara 7 called as 1hp AC is because it Nominal Capacity is 8,400Btuh regardless of it actual power consumption.

After read the daikin urusara brochure, I understand now. It look like gimmick.

The running 430w is in economy mode. It mean the aircon will cap at 430w when using this mode. The economy mode program the inverter to slow down the compressor to 430w running and won't allowed more than that.

So if you start the aircon in this mode, it wil take longer time to cool. Best is after cool, than switch to this mode.

The aircon itself is still a 1hp running in inverter from 110w-880w.

at 430W (~ 2 Amp)  I'd rather to say it is in normal mode. well in the burst/turbo mode to cool the room at the desired temp it might run as high as 700-800 W (1hp). once it reached the desired temp, it will slow down to 430W or even lower at 110W.

I'm not  sure how you guys set the desired temp, but for my usage I use it to achieve the normal comfortable temp 24-28C (mostly 28C because it is comfort already). Anything colder close to 16C I bet it wont make any BIG difference with the non inverter.

I still believe there is an improvement on the power consumption/savings provided that you put at the correct/comfortable temp. Some more I measure the current consumption from the circuit breaker and it is close to the energy commission 5* rating @ 1492 kwh/year

Which aircon is the most quiet? Many have mentioned Panasonic, but I feel that it's not quiet enough (even with fan running at the lowest speed).
