personally, I would chose the Panasonic over the Sharp

Not sure how noisy is being defined. My Pana aircon is not not as noisy are those York (my neighbour's) Any motor will have some noise.

Quite standard. Their installation price is for 10ft copper piping only. If more, they will charge for the extra lengths.

These are the rates that I received for my aircon installer

Extra copper piping for 1 to 1.5 HP
Inverter - 16/FR
Non-Inverter - 12/FR

Really? What's was the complains?
Did not encountered major one so far...

why don't you try them out and then give your review later?

It is normally included when you purchase the aircon. No?

It can't be that lousy, that last only for one year. Even the cheapest no brand aircon can last for a few years

The additional should be around RM10-11/FR. Non conceal.

Better to get the shop whom you bought the aircon from to take a look at the set. If you call up Pana directly, there could be some changes.

My office using pana aircon. Still under warranty. Now one of the compressor is making loud noise when running. My office contacted the Pana directly. Was told that they confirm that the aircon is still under warranty. They could send their technician to check. If required, they will replace the compressor FOC but they will charge for labour.
So, you would be better off if you get the shop whom you bought the set from to take a look. Let them deal with Pana directly.
just my 2 sen

No offense meant. Why don't you read up the rest of the posting within this thread and you will have your answer immediately?

Are you planning to install them yourself after reading the horror stories about bad aircon installations.

I was advised that every few months, you should switched on the aircon and let them run.
If the aircon hp were to be based on calculations, it will always be on the higher side. For me, I just use 1hp in all rooms. For the living & dining, just use 1.5hp. Don't need very low temperature.

For my room that is located on the highest floor, 15' x 15' x 9.5' ht, using a 1hp AC is more than sufficient.
For living & dining area, unless the area is enclosed (i.e no cold escape thru the stairwell, etc), as I was advised, even a 3hp AC will not be sufficient. So, it's all down to individual requirement.
As for me, I just use 1.5hp plus the ceiling fan. Works fine for me.

Copper piping for inverter AC is slightly thicker than those for non-inverter. If you have install the thicker piping for the inverter, you could still use for the non-inverter. But not vise versa.

It will also depends on what is the temperature you are expecting form the AC. You have a staircase, which I presume is open to the upper floor. Thus source for cold air to escape. Unless your living & dining areas are enclosed, it will be difficult to achieve a very low temp.

Added on November 16, 2011, 9:02 amThe cost for the inverter copper piping is not very much from the non-inverter ones. Considering this over the total renovation cost and the need to hack and replace the piping if sometime down the road, you decides otherwise.

For my case, I place the both the AC units at both ends of the living & dining.

install air curtain

This is the comment that I received from Panasonic Malaysia pertaining to my inverter aircon.

"Please note that installing Panasonic wall mounted Inverter type of air conditioner [1.0hp – 2.5hp using R410A as refrigerant] requires a minimum of 0.6mm thickness of copper piping and indoor and outdoor units must be connected with 4 wires (which are live, neutral, communication and earth wires). "

Hope this helps...
