My parents had 2 of those Kenmore units up until about 1990 or so.  They were awesome!  I wish we had kept them, as the newer ones don't seem to blow as cold.
 
 

 

That 8,000 BTU Kenmore was the exact AC my parents had in their bedroom at the vacation house for 30 yrs. It was still working when replaced for another new Kenmore unit in 2009. While it is smaller, quieter and more energy efficient, the quality certainly has vanished.  I had the 6000 BTU model in my bedroom.
 
Eddie,

I have a MW Signature similar to the one you posted but 15,000 BTU.

 



 

They were made by Frigidaire (GM). 

 

Here's a 115V 12,600 BTU that I have, it's much larger than the 15,000 BTU Signature I have and just two inches narrower and two inches shorter and it's even 1/8" longer then the big 30,000 unit.

Carry Cool

I still have the sears version of the carry cool, only use it when guests come still a great air conditioner, COLD! and fairly quiet for its age, the side panels are even intact
 
I got another a/c this weekend. A small 5950 BTU Frigidaire from 1978 that was advertised on Craigslist in New Hampshire. it works great and it has the "Electri-Saver" feature that's lacking on my other air conditioners.

It's the exact same size as the 1971 8000 BTU unit I got last year.





 
I don't know, I don't see why later systems still using R-22 refrigerant would be less effective. I never had one new enough to have anything else. I have a 10,000 BTU Fedders (not a weather wheel unit) that's about 12 years old (it's new enough to have a remote control and it's still made in the USA) and it cools very well but it's noise level is very high and it makes the whole house vibrate when the compressor kicks in (I don't use it anymore). The Fedders also lacks the feature that makes the fan stop when the thermostat opens. There's an energy saver mode on the Fedders but I never really figured what it really does. I think it just keeps the 3 speed fan on low speed... And the plastic front is starting to get yellowish, I'd rather have an A/C with a beige, dark brown or woodgrain cover than a white one that gets yellow (just like those white plastic refrigerator door handles from the late nineties).

 

The Frigidaire appears noisy in this video but it really isn't!



 

 
 
My parents had a 10,000 btu Norge with a wood (not wood grain) front. It was bought in the spring of 1964 and cooled our different apartments and house for years. The air that came out was ice cold. Mom hung a curtain at the top of the stairs. Upstairs stayed cool and downstairs comfortable.

In '87 I was working at Caldor and bought an 5,000 btu Emerson Quiet Cool for my room, parents bought another for their own room and the Norge moved downstairs to the dining room. The Norge wound up getting loaned to a friend who needed one and from there to another, and another, and another... My parents lost track of it about 10(?) years ago and as of then it was still humming just as smoothly as it was in 1964. Not one single problem ever!
 
just to interrupt the fun here - I like this thread, thanks for the interesting photos and comments. I have seen the Emerson Quiet Kool mentioned before, but it's the older ones from the 70s or 80s that are favored?

thanks again.
 
Hopefully nobody smoked around any of these. In college I had an apartment that had a through the wall A/C & Heating unit. Whenever you turned the thing on it smelled like an old ashtray for quite some time. Never could get the smell out of it.
 
Nice thing about those a/c's (reply #18) was that you could aim the air where you wanted it. That's important when placement is not the best for overall cooling. With a lot of the newer units the direction is very limited; you can move the levers to your heart's content, but the direction of air flow doesn't change much

Frigidaire Unit - PhilR

I'm wondering what the "Electri-Saver" button is doing on this model...

 

Is it cycling the fan, or eliminating something else from the circuit, or perhaps allowing a greater swing in temperature between cycles?
 
RE: #18 -- I'VE REPLIED 5 TIMES SINCE SUNDAY......

and Absolutely NO Reply back. I love the old
Circular Vent A/C units. I definitely want
this one, and Yogitunes said he would bring it
back for me, from Pittsburgh this weekend, on the
way back from Jerry's Wash-In.

Seemed Ideal. Except it's another CL Bozo playing
games. I know it's Rhetorical.....But What Is the
Use of Posting an Ad if you Refuse to Respond to a
Prospective Buyer?

Geesh....So Close yet So far.

Thanks Martin for offering to fetch it for me.
Looks like I'm SOL, thanks to the Seller.

Anyway....

HAVE a GREAT TIME AT JERRY'S EVERYONE!!
 
Electri-Saver mode

"Electri-Saver mode is cycling the fan off at the same time as the compressor when the thermostat opens. "

My newish Friedrich Wallmaster does this if one selects the power saver mode. After initial misgivings quite fancy it!

Makes sense as well not to blow recirculate dry cool air through the AC when the condenser is not on. This way the air does not pick up moisture from inside the AC and spread it around.

Have a huge then or so year old commercial fan that we use with or without the AC. When the AC is on is helps push and circulate the air further and more effectively than the wall unit can. Fan will also move the cooled and dry indoor air about when the AC is cycled off (fan and condenser) with the "energy saver" option.
 
 
Friedrich units with non-electronic controls for many years have featured a small heating resistor (anticipator) clamped to the thermostat sensing bulb to help trigger them to cycle-on within a reasonable time-frame when run on the energy saver setting.  This also promotes better humidity control.

Windows units that don't have this design tend to lag in responding to the room temp in energy-saver mode because the thermostat sensing bulb is near or clamped to the evaporator coil, which remains cold for some while after the unit cycles off with no airflow.

Electronic-control units (of any brand) may run the fan briefly every 10 mins or whatever is the design cycle when "off" to refresh the thermostat on the room temp ... and/or feature a remote control with temp sensor that can be placed in the room away from the unit.
 
Yes, when using "energy savings" settings every ten or so minutes (forget which)the Friedrich Wallmaster will power on just the fan. IIRC from the manual this is done to "test" room air to test current indoor room temp. You can here a slight click if the condenser comes on.
 
All very interesting. Thanks for the response to my question above!

 

I don't believe I've seen a wall unit here in Australia with such a feature - but I haven't seen all that many units, so maybe I'm missing something. 

It certainly doesn't seem common on modern ones!
 
My Frigidaire as well as my Hotpoint a/c with the Electri-Saver/Econo modes don't cycle back on as quickly on this mode because of what DADoES explains. The sensing bulb gets colder for a while as it's next to the evaporator that keeps it cool for a while after it cycles off... It's still useful when you want it to keep a room cool while your not there. I have another a/c that is controlled by a line thermostat on the outlet as it doesn't have the "econo" mode. It works but I had the bad idea to locate the thermostat just below the a/c so it also gets the cool air from the evaporator once the a/c shuts off and takes a while to switch back on. Again, this is good to use when you're not around and you don't want the fan to run constantly.
