Welcome to the group.
"Not all the older units were that inefficient." When I was a kid I used the E.E.R. formula that had just come out to calculate the efficiency of my parents' 1964 Norge 10,300 btu unit. I got the formula out of the Sears catalogue. The Norge came out to 7.5 and IIRC, 7.5 and up got the label of "high-efficiency" back then.
"Older units blew much colder air." I agree, however another factor is dehumidification. In general the lower the humidity is, the higher the temp can get before people become uncomfortable. Newer units do not dehumidify as well as older ones. I seem to recall some discussion of this in late summer. It was just before my heart surgery so I wasn't too attentive. Anyone recall this?
