if next time any leaking or changes easy to repair compare to inside wall. correct?

If there is leaking and is inside the plaster ceiling than is not just repair of the leak your plaster ceiling will damage too. Talk easy maintenance is never to conceal. Either way of conceal will surely be difficult to repair

It depend how the installer run the piping and to where the outdoor unit place.

You still need to conceal it after the piping comeout from the plaster ceiling. And terminate at the aircon.

But piping inside the plaster ceiling don't need to be conceal. It is like no logic and cost you more to hide the piping inside the wall. While the piping can't be see inside the plaster ceiling.

But 1 thing must be take note is the piping must be insulated properly without any pipe expose. Cause the condensation water will drip down to the plaster ceiling and spoil it. Later you can see some watermark on it.

Hello. I found this old post. I am looking do conceal my aircond piping as it looks very ugly now. Anyone can recommend a contractor? What is the price? I am looking to deal direct with the sub con workers .. no ID firm.. thanks
