I had an oldie with a fin-less circular coil in our first house that was quiet, built like a tank aside from missing the front and back of the cabinet and condensed water like crazy. Stupidly, I left it for the new owners when we sold that house.
For the next house I went thru two cheap Sears/Kenmore units. Each died in about 1-2yrs. They were extremely loud and vibrated a lot.
Next went with a Fedders or Fredrick? Old-school looking wood-grained cabinet unit. It died in LESS than a year! I took it in under warranty and a new compressor couldn't be had for it.
Since then, I've had a digital controlled Danby unit that's been excellent. I've had this one for 3yrs now. I'd recommend Danby if you're going new.
