@DBreezy, our Kolin 1.5hp inverter split-type a/c has been trouble-free (knock on wood) for 4 mos now. Kolin is also used in the company I work for & has been relatively trouble-free (compared to other brands). Our electric bill did not go up when using this a/c more frequently than the old non-inverter 1 hp window type a/c. Our Panasonic inverter ref is just 1-mos old & we haven't gotten our latest Meralco bill for me to comment on its performance. Wifey loves the 2-door arrangement for the ref & the bottom drawer for the freezer. There was a comment on this type of ref a few posts up. Sorry, we don't have an inverter washing machine. If we can get savings from the inverter ref, maybe the machine machine is the next purchase target. It will help relieve me of my Saturday washing chores!!
