Hi,

Yes that is normal, most all have return at top or front of furnace using the home itself as the return pathway.


You can add a/c and upgrade to a newer furnace, just have to be sure they are designed for use in a manufactured home.


Has to fit dimension wise and have a MH duct rated blower motor due to the small duct system in MH's.


For an electric furnace and a split system a/c, your A-Coil (evaporator coil) would sit atop the furnace.


Some furnaces use an a-coil shelf to sit it on, others just sit it atop as furnace is designed for it.


Best to find an HVAC Contractor who installs and services MH units to see what is available.


I started about the time you finished, so yes, it has changed drasticly in that time period.



Take care and best wishes,
Robert
