been using for more than 7 yrs, still great.

I hate my panasonic inverter PC boards have failed 2 x in 4 years (warranty runs out this year and I arent waiting) Is useless for heating The inverter runs in protection mode most of the time in winter meaning I can never get full output and "powerful mode" is a blatant lie the heating is really drafty Sadest thing is I sell airconditioners for a living and I inflicted this pain upon myself It's coming out next Tuesday to be replaced by a Mitsubishi Electric -chalking it up to experience and moving on

Got two, a 5600 BTU and a 7800 BTU. Both quick, cool, quiet, efficient, dependable.
