Condo Purchase - 21 yr old AC Unit

[Mohan P.]

Hi,

I am under contract for a Condo that is built in 2000 and it has Original AC still running. I see the inside unit has some rust but otherwise the AC unit still is operational.

Should I go back and ask for some sort of credit assuming the failure of the unit very soon or do I have any otherway to protect my investment?

TIA
