I have the definition but maybe Hvac guy talk will help Thanks.

The AC side of this unit is toast and the heating side is also down but they will opt to get it going. I looked real good for cracks but of course thing is a tank. Just like the old cast iron unit heaters last forever. The new ones if run hard will crack. Just don't make things like they used to.
