In Pennsylvania a 1500 sq. ft. 2 story house.
26 years old.
Gas heat pump installed now.
How much would it cost to have a new heater & central air conditioner
installed.
Asking because i am thinking about buying this house & it doesn't have
central air.



Get an HVAC company out and pay them for a service call to evaluate. THEN
you will have something decent to run numbers with.

As mentioned, individual differences can make a big difference. Any part(s)
of the existing system not evaluated/replaced, including ductwork, can
significantly reduce the potential of all the new stuff.
