York is not a good brand. I have 2 york at my office.

1st install, water drips. Fixed on the spot.
1st month, very cold. I mean VERY COLD, not just COOL. I am impressed.
2nd month, average.
3rd month, air-cond breakdown due to the area where the outdoor unit is installed. The area doesn't have enough room to dissipate heat (but the area has aluminium lining that allows air to go out)
4th month, from very cold become cool air then eventually it just went straight downhill.

One break down, it's ok. But two york breakdown at the same time? And service is bad. They come and didn't settle my problem. Just ASK me to open the aluminium lining to reveal the air cond to dissipate the heat and he even told me if I didn't do that, the aircond unit will breakdown faster in 1 year time. But all my neighbors in the office lots doesn't have these problem, why my York so special??

I agree that York is not a good brand. The indoor unit build is like cheap plastic unlike the Mitsubishi I used at home.

Go for Mitsubishi. The price is a little bit more expensive but more worth the hassle.

Thanks for the review, I'm actually cracking my head lately undecided whether to get York or Mitshubishi...
I need to buy some 1 hp, 2.5 hp and a cassette aircond of 2.5/3.0 hp...
I was considering York for its feature of i-plasma (wall mount unit)  and ionizer for cassette aircond.....but mitsubishi only 1.0 hp and 1.5hp wall mount aircond come with plasma...

My aircond installer recommend me Daikin inverter 2hp for my living hall. Fr what I gather here, no need to use inverter type for large hall area. Reason being that since compressor will not be start-stopping, so inverter tech will not be fully utilize for cost savings. Is this true?

Btw, anyone here knows the price for inverter and non-inverter type? Tq.

What's the best offer you guy got for Mitsubishi Mr Slim 1hp and 1.5hp and where you guys got it.

I got RM1000 for 1hp include installation.
RM1420 for 1.5hp include installation.

Is the price for mitshubishi unit without plasma? I've been quoted rm1110 for plasma 1.0hp without installation coz my main con gonna install it..

Wanna ask... Normally the shops will offer advices on how the air-fond arrangement will be like? I.e. how many hp for which room etc? This has to be planned even before the renovation? Sorry, am a bit confused.

normal room size 3m x 3m x 3m high for 1hp
bigger room size 3m x 5m x 3m high for 1.5hp
bigger a big like living hall size 4m x 6-7m x 3m high for 2hp
large size 5-6m x 8m x 3m high for 2.5hp

high ceiling 5-6m high x 3m x 3m can use 1hp
high ceiling 6m high x 3m x 4.5m can use 1.5hp

all quote from inverter unit only.

Like what your contractor suggest, use insulation for refrigerant pipes and condensate drain pipe.
