both brand for all models you survey is on highside

ME have good warranty but price is slightly higher than Panasonic...BUT design and feature is not as nice as Pana

Pana get the 5 star power rating series....long run am sure you wanna safe electricity.

Still the same, survey few shops before decide. I guess this is RSP?

what your MAX budget for 1 and 1.5 and 2HP (*exclude installation)

Life is cheap n also human life is shorter now, can do your best just go ahead, you won't disappointed of what you decided.

Yup two cost, but if you want cheaper can request the guy who you engage to do the piping to install the air cond for you. The air cond you can scout around for best price without installation. For inverter you will need min 4 core wire (Live,Neutral,Earth and Data)

My other concern on conceal is if leak happen, then it will be difficult to determine and replace the air cond tubing, but now I feel the easier way is to conceal a PVC ducting of suitable size for straight run, so future installer can just remove the tubing and change it to new one if required.
