I had an interesting conversation with the air-cond service man that came to service my mom's house.
My mom is using York and Panasonic air-cond.
He does all brands air-cond service (chap pa lang)
I asked what he thinks is the best brand. 
With the current advertisement, I wanted to install Panasonic. 

Below are the salient points of our discussion

1. Daikin - It has the best build (thicker material), good quality, good technology, No.1 in Singapore, has links with Acson and York, he totally recommend, price not much different than Panasonic, was absent from Malaysia market awhile due to bad distributor but now making a strong comeback thus no problem with spare-parts, loud because it has a strong blower thus cools the room faster, only air cond with inverter that can use regular gas.

2. Panasonic - The build has gone thinner, the second brand he recommend after Daikin, well established in Malaysia thus no problem with spare parts,
loud because it has a strong blower thus cools the room faster.

Other brands - avoid if possible

A Korean brand who also produce mobile phone - avoid like plague. 

Reporting from KL. 

Did not ask specifically. It seems that this sentiment is also shared by my wetwork contractor.
Any other members have this experience? 

The air cond contractor I spoke to earlier and the Legend Hi Fi Salesman told me this, Daikin Inverter air cond is the only inverter air cond that uses regular non inverter gas. Thus service charge is the same.
Is the service charge the same. ??

How is the design of the compressor better?

Oh ok. I was wondering because the compressor looks to be almost the same as any other aircond. I use Daikin.

Oh no They are still functioning well, just a year plus.

Can't remember the exact model number. Bought it more than a year ago. Inverter units all of them, uses R22 gas. FTKD models. 2x1.5 HP and 2x1HP.

Just installed York M Series. Not sure whether it's a new model or not. York website was designed by a Form 1 student I think.

One thing about daikin is that it seems to have an issue with the water condensation... very easily will start to have water coming out from the blower if the piping is not installed properly... also it takes abit more time to cool down... make sure the fins for the blower unit and compressor is cleaned regularly... this is what i experienced about diakin for a few years.... other than that.... no major issues like pcb failures etc... and still very quiet....
i also have national and panasonic models which are also a few years old.... the blower is now very noisy, the louver broke or something.... the plastic dont seem to be having a very good quality
