HVAC!

Hi guys!

I have a 3 unit apartment building. Currently doing corporate rentals with the bottom two.

Its an older home, brick, but no insulation between the bottom and top and none in the walls.

Thought about applying insulation but even DIY foam kits are cost prohibitive and the coverage is iffy anyway because you can't really see what your doing.

There is duct work under the house. Currently one package unit handles both apartments, a throwback to when it was one apartment before I split the bottom into two equal sized units.

Corporate tenants expect good things, so I have to give them separate control, which either means adding another package unit and splitting the old rusting ductwork, or putting in a mini split system, which I figure will be more efficient

I guess my question is, in a house with not much insulation, would a mini split more efficient than a package unit for a person like me who is paying all the bills?
