Here my actual experience. First aircon is panasonic non inverter 1hp using 8hr for sleep. Bill average rm110. Run  about 8-9yrs before it finally spoil.

Replace a new Panasonic inverter 1.5hp. Same usage. Bill cost me average rm70. Already running 5yrs till now.

First yrs already get back my return compare non inverter. Base on the last time bill and current bill. 5yrs now I already save rm2400. The save Can use for service the aircon many many time.

No matter how many hr using, it still save. Long or short. Sometime I find you guy are very slow to adopt the technology which is already more than 10yrs old. And still undecided it now.  hmm.gif

Panasonic, non-inverter, 1hp. Same situation. Only use in bedroom during 8hours of sleep. Bedroom size is roughly ~100 sqf, cant remember (standard pkns low-cost apartment in shah alam).

For the past 2 years, elec bill average ~RM80.

Then, moved to a new condo last week, first service done prior to reinstall. Damn cold now, feels like new aircond installed hehe.. Anyway, now bedroom size is 3.3m x 3.85m = 12.705 m² @ 136.76 sqf. Waiting for the new elec bill. hmm.gif

Room size in meter

1hp for 3x4 = 12sm (15sm) do not exit 15 sq meter.

1.5hp for 5x4 (25sm)

2hp for 6x5.5 (33sm)

2.5hp for 7x6 (45sm)

Once exit the room size meaning under power would be used more waste energy

Height is does not matter how height of that, more than 5m in 3x4m for 1hp still keep cold.

Cold air would going down 1st.
