Can install ceiling fan to help the aircon, no?

I double checked w/ the Malaysia Panasonic headquarters, the LED for my Panasonic air cond, blue, red, orange= the air quality indicator, not all air cond LED= power/ anything else.

From what I have read, R22 or Freon will be banned by year 2016. With this ban you can be sure Freon will be scarce and hard to come by. As such its price will significantly rise.
Puron or R-410A should by then be much cheaper than Freon.
I think it makes for good economic sense to go with Puron now as it is already 2014. Only less than 2 years to go before Freon's price should rise drastically.

Yeah I've already switch off this function. Finally it performs like an air-cond. Not heater. 

Pana is ok for the overall, just slighly slower cooling time to compare others brand.

York my kampong one the indoor blower bearing rubber lost within 2 yrs time.
Once service and created heavy vibration noise at all.

maybe under Daikin can be solve out.

Guys , When servicing the compressor of the aircond , normally the contractor will charge higher fee when its place on the roof ? Im advised by my contractor to hide the compressors at roof slab of double storey house . I need to decide whether to put on the roof slab with shorter piping OR to put somewhere easier to reach but with longer piping

Your England is indeed powderful, hard to understand... 

Each brand will have different BTU due to their set up, but each brand of air-cond will still blow the cool air, if the BTU is smaller, surely it cool down slower.

Yes, each brand's efficiency is different due to their design/material used etc,  but every air-cond sure will blow out cool air, certainly it won't be needing 2 hours to cool down a room if there is no undersize issue or external issue.

Air-cond not cold, then surely something is wrong with the air-cond, either gas leaking, problem in evaporation, heat exchange, blower fail to deliver due to clogged, there is no air-cond being designed and manufacturers that cannot blow out cool air to cool down a room. If said faster or slower to achieve 25c due to BTU and efficiency issue, then yes, each brand could be different.

But to say 23c A brand is same with 25c B brand is some powderful science out of nowhere.

23c never will be the same with 25c unless the air-cond thermostat has error in detecting the temperature.

You can say A brand is more efficiency, cool down to 23c faster, while B brand achieve 23c slower or hard to achieve, then it makes sense in the statement.
Mind that you set the temperature at the remote control at 23c, doesn't mean your room will be 23c, it just means the compressor is told that once achieved 23c, it can stop working (in non-inverter), or slow down significant (in inverter), it doesn't mean the air blowed out is delivered at 23c.

day by day I found kimsim is dellusional

It is not the temperature, but other reason. The people ontop already explain to you.

Beside temperature, there is this call humid which also influence your cool feeling.

I think his speedo is mph. Your 1 is KM/h. 

That is user faulty... No wonder you can't save much

Like a car cushion leather seat, fatty body can be boken the seat cover and blame to MFG design not up to quality

As a MFG since they already meantion on over an Internet website.

25C as a guide line for you to saving energy, inverter was variable speed, even Increse or decrease one degree can tell that keep warm or cold.

From 25c to 24c pre-set from that outdoor fan motor will starter runs faster to meet up your pre-set.

If over setting like 23c or set to high fan speed from that computer would telling outside compressor & fan motor runs like jet high speed.

In this case set to 23c inverter outdoor unit already tell you that runs out over speed and does not meant you can save more.

From non-inverter were fixed speed they didn't tell, from starter runs in high speed till pre-set are reached and slow down or compressor cut-off.

But indoor how? Could you get the same cold air blowing out? Or warm air?
(Sensitive person will wakeup or suddenly what happening or blackout)

From inverter you would feels that cold air stopping blow out, but still maintenance the room temp, until the computer outside and indoor change then compressor start runs again, but that is called parts load from very minimum input watt load.

I dunno you guy how to in proper usage

Cherroy already explain to you la. You don't understand his explain is it?

This is not the Aircon problem.

Just use your way to save.

Ha ha how much time you can wait from non-inverter temperature reaching?

From my previous usages was taken around 3 hours at least.

Yes, R410 being run at higher pressure, hence the heat exchange "cold" faster then R22, hence cooling effect will be much faster, but it doesn't mean your room become "colder" then non-inverter.
Cool faster /= colder.

Both inverter and non-inverter should slow down/cut off the compressor once their thermostat sense the temperature of room is dropping below the pre-set temperature.

Eg. A room with inverter, B room with non-inverter,
If both temperature is set at 26c, thermometer should be getting reading of 26c in both room.

Office who wanna bother?

Room more important as your sleep and comfort time.
Even one degree more warmer you would realise the overall room temperature are hot.

I think you have to explain to him in mandarin.
