I've been on the hunt for a vintage A/C unit for at least a year now, and it seems they are super rare around here. I need a 5000 btu (or less, I know some are less) for my bedroom because it never cools properly with the central air, and I sleep best when it's COLD. I'm on about 4 years with a cheap modern unit but it has it's share of squeaks and rattles, and as of this fall, it really wasn't cooling all that great. It has been totally cleaned every season, never run with a dirty filter etc, but seems like it's had it's day. I had a couple older ones (probably 70's-80's vintage) before we moved 4 years ago, but gave them away because I didn't think we would need them in a house with central air. Wrong. I did pick up a really neat old Whirlpool Dehumidifier a couple summers ago, truly little old lady owned, I got it at an estate sale for cheap because the fan had seized and it wouldn't collect water anymore. A few minutes with some 3 in 1 motor oil and some twisting and turning and it runs like new... After a thorough cleaning it has purred along the last two summers, oh so quietly. Does a great job (actually I think better than our modern 30 pint unit, and the Whirlpool is only 14 pint...) I think I looked it up and it was built in 68. No full pan shutoff, and the humidistat is dead, but it works great!
