BTW, I just saw Daikin ads today in STAR paper that its latest Inverter AC can use standard/normal copper piping... need not be any thing special...

So far I'm using Mitsubishi Mr Slim. One thing nice about it, they are quiet and easy to use. Not the most beautiful but I had them for 10 yrs now and working fine.

One thing nice about it its come with self diagnostic error indicator to help narrow down on what failure its encountered. One time, it wasn't kick in at all, the Compressor is not running, just blowing air. The LED was blinking in some same sequence. Reading my manual and calling the cust Service, they ask the blinking sequence. It was the starter condensor which have failed. Cost less than RM100 for them to come (on time) and replace it..

If you need fast cooling, just press powerful cool on the remote. It will kicks in high cooling fan and instant cool air for a few mins and then it will revert back to the original mode.

I use the powerful cool mode whenever I need rapid cooling, but usually just econo mode.

BTW, my living room on 1.5hp model and I only set my fan speed to 1(lowest) and 28c. 29c after the room become cool..

If you really like it cool and not loading your AC and electric bills, you can use this trick. Switch on a floor fan (DO NOT USE CEILING FAN). This way you get a much increase cooling when the floor fan increase the wind speed and volume at the cool zone level ie close to the floor (Remember physic law, cold air drop and hot air rise?) so ceiling fan will unnecessary ruin the cool comfort zone where you seating at ie couch or your floor....

Half of the time, we off the AC after 2 hrs because it just get too cold with the fan...
