average usage per day is....?

I have bad experience with Samsung... 2 of my inverter Samsung died (triangle model, 3 years old only). Dead outdoor unit controller board. They quote RM600 to replace it. 

If you have money any Japanese brand except Sharp (not sure how is their quality after China bought some their shares) is good to go. Panasonic, DAIKIN, Mitsubishi, Toshiba.

If tight budget, you can go for Gree or Media. These 2 are top brand in China but personally for AC I prefer Gree because they seems to focus on AC product.

And get an inverter, and try to learn how to set your AC temperature. 24 C - 25 C is the ideal comfort zone for human.

Stupid. Starting amp for non inverter is what causes high usage of electricity.

oh really.. 3 years still new..wow. im very tempting to change to samsung smart aircond. but since my panasonic inverter still working fine. only the white cover already change to a bit yellowish..its a waste of money.
samsung warranty 1 years only right? aww sad la.

outdoor unit control box? your outdoor unit installed exposed to rain/sun? mine the control unit installed inside the car parking roof. its 100% avoid from direct sunlight and rain.

not anymore, tat is old tech ady, if u still using those aircon better change

Depends on the place u r using .

Inverter concept in a simplified version :

Inverter Compressor can work from 10 % of Cooling load to 100 % load . At 100 % cooling load, the power requirement is slightly higher than a non inverter version . The savings occur when , your cooling load is not as high allowing the unit to run at part load . This is the moment where energy savings occur .

Non inverter concept :

Non inverter compressor runs at 2 points . O% load and 100 % load . When u switch on , compressor will run at 100 % . When desired room condition is meet , compressor will continuesly run until room temperature continue to drop ( maybe thermostat detects , room below 18 deg c ) , where it will cut off compressor and wait the room to hit 25 deg C before starting to run the compressor back .

So , if you wish to know where is suitable to use inverter : 

Your bedrooms : USE INVERTER . Unless u r undersizing the ur DX Split . if ur room height is standard 2 m tall with all windows covered by curtains , you may apply 55 btu/hr per sqft .
Living room :

Use non inverter. Most houses usually undersize the living room dx split . It's meant for spot cooling . Even when u use inverter compressor , the savings doesnt take place cos your unit will end up running at 100 % anyway .

I hope this clarifies your request and kindly feel free to contact me if you need further explanation .

in terms of brand to go for :

Hands down to mitsubishi electric and hitachi . Dont fall for Daikin / Heavy industry / Midea / Gree / Trane / Panasonic / Haier / Jalan Pasar split .

Is it becos  of the board has been shorted/fried?
I heard people recommending spray a layer of pcb coating, to minimise exposure to moisture & creatures (lizard) getting onto board and short he circuits.

Not sure why the PCB fried.    Extra coating what so ever - that the responsibility of the manufacturer... not the buyer. It's supposed to last a considerable time. The outdoor unit should work even under direct sun / rain. 

Lel. All motors have inrush current.

i belip wat he said is those bery old aircon with no / bery small capacitor & slow step up motor & switching etc
4get the exact term they use whn explain 2 me, ofcauz i'm not saying it does not eliminate it but rather reduce it
whn u compare those with new inverter tech + all those; ofcauz the current pull consumption is high & not stable
but as wat the aircon guy explain 2 me, new non inverter is bery efficient ady as it include those as well

not saying inverter does not save electric but it depend on situation & it some case might cost more
the saving of inverter is very small to might cost u more especially whn u c ppl said 25-27 degree & in mid turn off & on like tat
u onli c the difference whn u on at 23 degree below to 15 degree & for long hours

i actually experience it with my cassette aircon, inverter & non inverter
where the inverter actually cost more to run whn i set it at 25 degree & onli notice the saving whn i set it at 23 degree

but cost aside another advantage of inverter is the comfort,
no sudden cold & hot, i would choose it over non inverter anytime regardless of cost

Inverter u need run more thn 8hrs only save eletricity.plus inverter if rosak can throw oledi

Dah dah dah.

Just admit that you are talking shit.

Simple explanation are the lower RPM the lower Watt use if ac max power are 800watt and the higher BTU the faster they cold when purchase ac same price ignore those purifier PCB blah coated shit  Fancy thing looks for BTU instead

Most faulty ac when repair they are either change the compressor or add on More higher capacitor if not a logical board issue, due to when compressor cylinder damage the default power to push are limited happen sudden stop or power Trip sometime

when using bigger capacitor just increase more power into compressor push the limitations for temporary or force compressor to run eventually we call over loaded in the end your compressor using more power more power hungry more hotter and your 2.5mm house wiring could burn or melted then could be damage other wiring as well

My shop have 4 ac 2 1.5hp 1 1hp and 1 2hp after replace same hp but non inverter just a regular r410a all down light change to led

Every month my tnb Bill only save rm150 to 200 compare to RM 850 or 900

Or you can try add a bigger capacitor into to your regular ceiling fan it will spin very fast like no tomorrow after 10 minutes fan motor eventually smoke and fire then power Trip since all motor have a maximum power limitations
