Panasonic NKR Reverse Cycle Inverter

Hi guys, we have had our air conditioner for 14 months and in this past week on the extremely hot 40+ days it started blowing hot air even though it was on 21 degress and cooling function! We tried everything with it, cleaned filters, checked drainage...

Panasonic cs-e18nkr operates and acts funny some times for example lights are blinking for no reason and you look at operating manual to find why these lights are blinking ??? you find this is secret !!! and no one tells you why this device operates...

Three service calls in the first few weeks due to noise problems. Unit made a noise when turned off with remote control, which is unacceptable in bedroom. New part installed after 3 weeks. Still makes noises during the night, clicks, gurgling noises...
