dude/sis... I think your aircon is quite an old model... is either never service the air con or it is simply too old?

I suggest you upgrade it to inverter and your electric bill should be less than 200 for 8-9 hr usage every day. (saving 100 every montH)

Yes, it is a very old model.
I have serviced it twice within the last six months. But it is not giving me sufficient cold air in MBR. The other room were sufficently cold enough within a few minutes. I guess the MBR is over-used by the previous owner.

I need about two years to "breakeven" if I buy a $2400 model. Think it is wiser to buy new one. I shall check my elect bill again next mth..
