Thinking of installing a central air unit in an old house

got a 1920s tudor house. the house is basically all wood lath and plaster walls and ceiling. there is a partial attic that's can be access through crawl space.
unfinished basement. first floor is kitchen, living room, dining room, den and bath. second floor is 3 bedrooms and a bath. attic level there's one room.

i'm really trying to avoid installing split units since the unit inside is a bit big and clunky.

high velocity...that's a possibility...but can the air handler be installed in the basement? also i read the issue of hot and cold spots and how do i handle the return air if the air handler is in the basement.

then the traditional central air. i'm sure it can be done...but at the cost of losing closet space and possible breaking a bit more of the walls than i want to see happen.

so what do the pros and seasoned AC guys here recommend?

Easy easy easy! One system in attic to do the 2nd level. One system in basement to do first and basement.

traditional central air or HV? can one outside compressor/condenser unit handle both air handlers?

Not a pro and seasoned AC guy, just a satisfied homeowner, who definitely recommends that you talk with your local HV guys. Our home was built in 1970, so obviously newer than yours, and it's a ranch, so different circumstances in that regard, but we also have hot water baseboard heat, so no ducts. We installed a Unico system about 10 years ago, and, again, I am very satisfied. The only complaint I had was, during the first year, when the rest of the house was comfortable my office was constantly cold. But it is also the closest room to the return in the hall ceiling, so I throttled one of the two vents in that room, and it has been perfect ever since.

I agree.... 2 systems ........................ And, NO, one condensing unit can not work for both air handlers.
