I'm wondering where the TXV is normally installed? I had my new furnace and a/c installed yesterday and realized that I did not see a TXV when I looked over the system after the installer left.
I called this morning and was told it was installed inside the ductwork with the uncased coil to look cleaner and protect the valve. Is it possible for it to fit there? How much space does it take? From photos of TXV's I can't imagine it can fit inside the plenum.
