I came across a condensing unit that did not have a brand.
The model number was AA1BJ060-A
The serial number was 1994E04424
There was a product number of AA1BJX060000AAAA
It was roundish and looked to be less than 10 years old i.e. no rust or really faded paint but not shiny like a one new either.
There was “High Efficiency” in green in the middle of the fan area.
The air handler/furnace was a Payne brand so I checked my Preston’s Guide, but the Payne units don’t start with Alpha characters.
I also looked under Goodman, Bryant, Ruud, Rheem, Am. Standard, Trane, Tempstar, and Lennox. No luck with any of those.
I know this isn’t much to go on but I was hoping that someone may know who the made this unit.
