I have a "Wake The Dead" Whilrpool that was here when I bought the house. I use it during the rainy season and between A/C and Heater seasons when the basement gets a little dank.
It is loud, roaring loud. A few years back I though it had given up on me. The compressor would overheat within a few minutes of being turned on, and then would proceed to short cycle after that.
I was so happy, I was going to get a new one. But then the frugal part of me said there must be something causing it, and heck I'm going to get a new one anyway. So I tore it apart. I had had the front of a few times to clean the evaporator portion, but this time I took off the side panels and the foam blocks and looked at the condensor. It was plugged with dust. I gave it a good sucking with the Kirby, put it back together; and it's still running.
It still rattles, and drones, the fan sounds like a jet taking off; but it works. I have to empty the bucket about three times a day during the rainy season, and it sucks electricity like a full sized air conditioner. But it works.
