I would be glad to call the listing agent to ask the question regarding the cooling system, it may be part of the entire central cooling for the buildling.
It seems to be in good shape, it is a 1971 building so it has normal wear and tear and the interior is not modern. The monthy maintenance is 184.00 per month and the taxeswill be assessed on the new purchase price which is normally about 2% of the asseessed value. So that would be about 1000.00 per year..
I will post back here if I find out if the a/c is fairly new.
