the first and second time was under warranty. i called Panasonic and they arranged either contractor or their own people to come. the third time was after 2 years, the customer service just asked me if my unit is more than one year and i told her yes. then she said i have to call the contractors myself. she asked me where i live and gave numbers of contractors around that area. the best thing was, all the contractors whom i called told me their appointments are full! i have to wait more than 2 weeks! i had to call Panasonic again and release my anger at them and they gave me more numbers to call!!!  is this the kind of service u expect? at least Samsung will call for you and follow up for you even after your warranty is over.
i'm not the only one with this problem, there are other forummers who went through the same thing as me. pray hard that your Panasonic aircond doesn't give u problem.

yes, their customer service hotline. the Panasonic airconds from year 2000 when they introduced the ionizer feature, that's when their qc went downhill. the old models esp under National brand were solid

Yah, I have 1HP Samsung triangle inverter unit. Not that cold even though the temperature setting is 23C, as for York Inverter, 25C is good enough  . The outdoor unit noise a bit higher compared to my York unit (adjacent room).

thanks for the info ... never had a portable aircond , surely not for me .. prefer split unit aircond

my last Panasonic aircond is with nanoe G loh. the pcb spoilt within 1 month of installation. nanoe led light didn't light up. when open up, the technician showed me the pcb is rusty. 

yes, mine is non inverter premium model with econavi and nanoe G function. u can imagine my frustration when within the first month, already so many issues with the aircond. and after 4 years it gave me problem again. what's past is past. i wont want to live through the nightmare again. i will only consider Panasonic for kitchen appliances.

my preferred brands are Mitsubishi, Toshiba/Carrier. Unfortunately, Toshiba/Carrier is not popular with dealers here.

In the Malaysia market, York today has no relationship to Daikin today.

Stop spreading inaccurate bull.

i have 4 units of Toshiba, 2 Mitsubishi, 2 Panasonic, 2 Sharp, 2 Trane, 1 York (latest by johnson controls) , 2 Acson, 1 Hitachi.
I can't vouch for Trane or Sharp as these were installed by developers at my condo units and i do not know how much my tenants use them but so far no complains from them after more than 2 years.
as for the Toshibas, combined together , the Toshibas have the longest working hours and none have given me any single problem for the last 10 years. don't even have to pump gas. Mitsubishi also no problem. Panasonic countless of problem even have to go the customer service office to buy replacement part for the flap. Hitachi broke down once. the acson didn't breakdown but only the compressors are damn noisy and making booming and clanking noise.
i guess i don't have luck with panasonic. the Daikin models, if they are those models with technology inherited from OYL days, they're no good.
York is no longer under Daikin. it has been sold to Johnson Controls and now made in China. but i must say, i'm impresed with the quiet compressor.

The Samsung indoor unit not that noisy. Similar with my York (inverter) and Panasonic (inverter). It's outdoor unit is noisier that the other two.

All my AC is inverter unit. Ditch out non inverter 3 years ago. Significant drop in energy usage, a lot less to pay to TNB  .  3 unit 1hp long working hours (9hrs min daily), paying RM280-RM300 only to TNB  .

Samsung unit, I have to set to 22C... that's equivalent to 25C on my York and Panasonic. Maybe the thermometer calibration is wrong.

Energy expenditure all unit are similar (I've tested it using power meter like this) About 250W to 900W.    Depends on the cooling load.

York design is nice. You can see the temperature no at bottom right. 

why ? some said non inverter the cool air bit better then inverter , correct me if i wrong

owh got it , thanx 

owh got it , thanx 

Normally I on aircond 2-3 hours only per daily....

im thinking to get a new aircond around october , but i wonder which is better inverter or without inverter ?

usually i will turn on the aircond 7pm till 6am sometimes 7am plus .. so inverter for me

currently im using panasonin non inverter ... there is 2 brands in my mind , either york or daikin

Panasonic, Sharp & Hitachi? Which is preferred
