I guess I'm weird.  I wouldn't want an old, inefficient A/C unit like this to make my electric bill higher.

Might be worth it to have something without a single Chinese part on it.

And while I don't know about this unit, there were high efficiency models In the late Sixties. Friedrich made one with an EER of 12.

Kevin, not all old air conditioners are inefficient. Some are but others are very close to today's units. I can't tell about this one.

Often, the most efficient ones are a bit oversized compared to their capacity. I have a 1974 115 volts 12,600 BTU air conditioner on the same chassis as models with about twice the capacity but it's EER of 9.6 is better than the EER of the larger capacity models. I have a 15,000 BTU 230 volts air conditioner from the same period on a smaller chassis and it's EER is just 5.4.

With an EER of 9.6, my 1974 air conditioner is comparable to today's less efficient models. I think Friederich even had some models in the early seventies with an EER of 12 which is close to today's most efficient models.

I guess this Admiral is from the early 1970s. This 1972 model has a similar grille but the controls are on the other side.

when it comes to EER ratings, didn't always mean it was more efficient, the higher the number only meant the thermostat was governed down, giving you a cool room, not icy cold....

nice thing about the older units, you could open it up and adjust your thermostat back up....

this A/C for example could be 'made' to save energy on your own, just by selecting the temp to a number 4 or 5 instead of a 8 or 9.....theres a choice, your way, or theirs....

nothing different than FL machines getting a TIER rating for water efficiency, you had a I, II, or III.....could all be from the same model, but the higher the number, the less water was added for a wash....

the machines were designed to do a better job with less water, it just reduced the amount of water allowed to be added.....

SEER vs. EER vs. COP

EER (Energy Efficiency Ratio) is BTU capacity to watts of power consumption at 95°F outdoor temp and 80°F return-air temp @ 50°F humidity.  It can be roughly calculated as BTU / Watts from the model/serial/rating tag.

SEER (Seasonal Energy Efficiency Ratio) is calculated from total BTU output and power consumption over the course of an entire cooling (and/or heating) season, which takes temperature variations into consideration.

There's also COP (Coefficient Of Performance) which is heat provided (or moved) per power consumed in the same unit of measure, and is typically marketed in relation to heat pumps.  A COP of 1 is equivalent to an EER of 3.4 (one watt of electricity = 3.412 BTU).

Nice unit! Simple looking but does the job.
