Sanyo? 15-20 years already? Even it is still working, it will be like draining your electric(not efficient at all) bill.
Sharp? Ok gua I guess, but is best that you check the consumption(W and A) before deciding.
Not to mention service center, is it near by your place?

It depends greatly how we use it, if trashing like no tomorrow, it will fail faster.
When the air cond still have warranty, I'll trash it(but electric bill will kill me) and if that is not owned by me also I'll trash it and see will it sustain. But not all brands can sustain

Indeed yes, but still ask opinion from sellers(3-4 shops) and service centers that service multiple brands. In Seremban, Ritak is the only service center that service Samsung, Philips, Toshiba, Pioneer. I sometimes have to buy parts from them(repairing my old Pioneer player), Samsung's appliances always in their shop while other Japs seldom. Ask them also they will say Samsung tends to fail faster during warranty period Again this can't really be a benchmark since you may think this is isolated case. But when I buy parts from Panasonic SC, air cond failure are the least comparing to other appliances(LED TV the most)
For me, buying Japs brand are for peace of mind while buying Kimchi brands are gambling my luck, so far my gambling luck sucks, so I won't gamble.
For electronic parts, it can fail faster can high maintenance cost. Like a donkey years ago Sony CRT TV I only need rm200 to repair a circuit board(lightning strike) but a Sony 47" LCD need rm3+++ to change the circuit board, due to IC leg are too near(can't be changed)

For inverter models with IC board fail, outside tech can do?
Sharp is ok what? They are still in the market means their product are not bad.

Samsung's TV no doubt is very bright but even sellers also don't recommend it if want to use for long hours.
That's why I never buy inverter, just the normal non inverter, less headache Any outsider also can do since less fragile electronic components are used

I trust what my seller told me rather than a fanboy's baseless and subjective remark

Well, I'm not OKU, so I never think of robot cleaner.
Also, too bright are good for doctor's business, why I want to waste more money for a TV that can deteriorate my health?

Most cooling coil are using aluminum, because of cost effective.

The most is you get a deal on installations.

Well, like this you will harder to get good deal

You can't wrong with Pana, Mitsubishi, Sharp
So the contributing reason will be after warranty parts replacement, like I won't buy a brand when the service center are > 20km from my house.

Dust is depend greatly on your house environment, if landed terrace house, the dust formation are more, especially the height are <8ft.

Have pre filter are good, still if your room have lots of cotton material and staying in terrace house, the most you can extend the interval between each service by 0.5-1 year.

My WM having warranty of 7 years for motor and I wash daily. It never fail during warranty period. So everyday I'm happily washing my laundries without problem.
I don't bother about 10-20 years warranty if it fails every now and then and during the outage, I need to get a replacement. Does this make sense?

Cheap does not means bad, expensive does not means good.

Toshiba, next will be Panasonic.
Why not Hitachi? Because of the cover locking mechanism, out of 10 failed WM, this is the most common failed part.
This same goes to FL WM, the door locking mechanism is the most fragile part after the circuit board.

Those 2 are the failed companies in this world. Too reliable

Mine are all 20A, from air cond to others
