I have 2 Quietmaster Programmable ACs (the ones just before the Kuhls) & a Panasonic model (can't remember exact model, about 4 years old).

I somewhat certain that some products in the CP line (blow vent on right) are made by Panasonic. I think I have a vague recollection on that info from years ago. My older Panasonic looks nearly identical to the current CP models (the electronic control panel is different).

The good news is that the Panasonic model has been a champ. Not nearly as loud as the Quietmaster on high & comparable on lower settings. The Quietmaster has a noticeable sound when the compressor kicks in - much more muted on the Panasonic model.

My QuietMasters have LG Korean compressors. I think the rest is US.

I would also like to point out the Quietmaster is a 115lb behemoth. Its also requires the included bracket when used thru-window. And its wide. The only thing you are missing out on is the higher EER - and the naproxin dose before&after. I'll be cursing it shortly as I put it in the window soon.

I tossed my old Friedrich AC because it wasn't enough BTUs - worked fine the day I hauled it to the curb (and someone took it).
