Mitsubishi Heavy Industries Avanti SRK60ZSXA-WF / SRC60ZSXA-W (6.0kW)

I read reviews here and all those people who said it was so quiet never mentioned how operational noise is really bad. Got the 6kW Avanti and as pointed out by another reviewer here it is the nosiest a/c I have ever experienced. When it just ticks along it is quiet but when it needs to do an operation the noise is just ridiculous. How could MHI not notice the louvre motors and high speed fan noise is pretty strange. Also no backlit remote control, even a cheap TCL has this and more. So disappointed with this purchase. Another reviewer mentioned a newer motherboard addresses some of this so I might contact MHI. I am about o buy another 6kW ac for another room but it might be Mitsubishi electric this time and seems to be the one to get.
