Unit is 25 yrs old, I'm sure not very efficient anymore. Heater works, but the compressor is dead. Before I get a couple of estimates I want to find out what's involved.

I assume I can still use the existing duct work. Can I still use the existing heat?
 
Sorry should have had all the info ready. 1800 sq ft, Payne 591AN036-A compressor, gas fired furnace up in the attic. So I assume that's a split unit?
 
At 25 years old , I would be inclined to install a new , higher efficiency system , indoor and out door .

If your ducts are OK , I suspect you can re-use them .

If you change from your current R22 system to a new R410a system , they are going to want to change out everything , including the copper refrigeration lines ( if that is practical ) . If that is not practical , they will have to flush the existing lines .

This is not going to be cheap . :-(

God bless
