Why do you say that I need a new furnace? I was asking about the A/C
system. My furnace works just fine.


Surely you aren't going to put a new air conditioner system on an old
furnace?

New furnaces are ~92-94% efficient. Furnaces that are older than about 12
years old are only 65% efficient at best.

Yes, you need a new furnace. Don't half-ass it.
