1. You may recoup close to 100% of it.
2. Even if you only recoup 70% or less however, it may help you house sell faster which will offset carrying costs.
Central air is almost a "must have" these days and my clients DO ask about the age of the unit.
If you decide to go this route, make sure to keep all the receipts and manufacturer warranties. Also, have your Realtor highlight the fact that you have new c/a in their marketing.
I hope you had a Realtr do a walkthru with you in case there is something else that should be done before you worry about the c/a.
Call or email if you need my opinion. I know Willow Grove and we represent homes in all price ranges.
Have a great day!
