I have read in other posts that Crane stopped making HVAC products in 1968. I inspected an electric furnace yesterday, house built in 1980. Seller disclosed Heat Pump is 2 yrs old. I think he must be referring to the compressor unit outside, which does look new.
The air handle S/N is B08233C9C. The Crane tag is still on the unit.I guess the “blackhorse” method indicates the unit is 2008?
I thought it may be original, that’s when the RE read the disclosure stating 2 yrs old.
