Ill try to condense my situation.
I've added a 900 square foot addition to my home, it will be heated/cooled with it's own system(york-gas furnace/ac)
The main house uses a trane heat pump tied in with a trane gas furnace.
My utility bills are consistantly the lowest in our neighborhood(by alot)
In order to build the addition i had the heat pump disconnected and moved to temporary storage.
Upon trying to re install said system(17years old) the idea of a replacement heat pump has come.
Can i combine a york heat pump with a trane furnace?
Is the dual heating cooling still a valid option?(i get a reduced rate on my electricity having the heat pump.)
Would you spend the money on new lines and labor to have the old heat pump reinstalled?
I appreciate your time in reading this and responding.
