i hear many people said inverter save if use more than 8 hours. and if rosak throw throw.
bought my panasonic inverter 1.0HP still working fine until today. bought it in 2012 during my first baby born. its already almost 7 years. my baby born in march 2012.
electricity also cheap. hardly reach RM100 per month (during hot season) sometimes RM40-RM50 only (normal season). (this amount include with my other electric device, i got cockoo water filter, Sharp refrigerator, LG washing machine. i dont have Desktop Computer at home. only use laptop. my wife also use laptop only.

but yeah i regularly service my aircond myself. just clean the filter. the deep service dont know how.

but i hear samsung 8 pole inverter aircond much saving electricity. if my panasonic inverter rosak i want to try samsung 8-pole pulak, with smart wife features too.
