Bro kimsim,

Need your advice on this;

My living + dinning area is 9.8ft (3m)(wide) x 25ft (7.5m)(length). Currently the ceiling height is 9ft but I will install flat plaster ceiling.

Based on pana online calculator, it recommend 1.5HP air con.

However, due to my unit are facing west, its very hot in the evening.

So, I plan to install one unit of 2.0HP air con instead, ME, model: MS-GH17VC (Non inverter type), From the catalogue, it say the required gas pipe size is 12.7mm, and I measure my current copper gas pipe size is 16mm (outer diameter), should be no problem with this model , right ?

Currently, the liquid & gas piping are pre-installed up to my living area. It's provided by the developer.

Kindly please advise me TQTQ

Thanks for your valuable advice, Bro kimsim
