sorry if this is the wrong place to post/ask this question. recently have been going through my storage unit trying to clean it out. still has lots of my dads old hvac stuff in there (mostly motors and contactors, etc..) which I'm tired of taking up room.

only thing that seems interesting is a new in box trane 5 ton scroll. well new as in hasn't been used, but it appears to be a 12-seer, single phase, so even I know it's not up to date seer standard. I used to go on some jobs with him as a kid and I know these things used to fetch a bit.

can anyone tell me if this is something I'd be able to sell? someone told me that anything below 14 seer is old news nowadays. any help would be greatly appreciated, thanks.
