I would almost have to say that the tall slender unit with the disconnect is an old GE from mid to late '60s vintage, at least 7.5 ton or more. The other dual condenser fan unit puzzles me. There is an older AT&T CO building north of me that has several of those units with the tall fan grille domes, they kind of look like the standard GE residential units from back then, but the grilles look too tall.
Sorry Kev, fooled you on #4. It was really PBR! I'm old, remember.
Speaking of old, Silver, you nailed the tall, thin unit. That's the one I didn't know. Had to fire up the 40x digital zoom on the pocket camera to read the tag falling off the back. The other one should be pretty easy. Looks like their smaller units but with 2 fans.
