Dear All Sifu-Sifu

,
I just bought an 950 sf apartment (3R2B) , below is my dilemma on the air-cond selection, kindly provide me some direction on the selection:
1) MasterRoom (10 ft[wide] X 10 ft[long] X 8 Ft [heights])
- Due to developer was conceal all the pipe in wall which provided only normal R22 pipe, if want to conceal all the pipe again for inverter cost me 1k~1.5k because of it take 25 ft distance. So I was aiming R22 pipe air cond. There is 2 choice that I aim : Panasonic (CS-C9PKH non inverter) or Daikin Inverter (FTKD-25GVM (1.0hp) non-inverter). Any idea on this 2 selection?
Is that Daikin inverter will more electricity saving compare to Panasonic Econavi only which this room will always open more than 8 hours for sleep time.
2) LivingRoom (10 ft [W] X 30 ft [L] X 8 ft )
- Easy to conceal the pipe, so no issue for inverter series. Aiming for Panasonic (CS-S18 PKH (2.0hp).
3) SecondRoom (10 ft[wide] X 10 ft[long] X 8 Ft [heights]) [Study & Computer Room]
- Easy to conceal the pipe, so no issue for inverter series. Aiming for Panasonic (CS-S10 PKH (1.0hp).
My main convert is electricity saver which I would like to hear all sifu opinion and hope to make me more clear on the chosen of air-cond . Pro and cons acceptable .
Thanks a lots.
