Adding an additional zone

I own a hi ranch home with an apartment on the first floor, the house is heated via gas boiler forced air system on one zone controlled by a thermostat on the second floor.

The heat generally works fine except for a variation of temperatures on the two floors and the fact that the duct system acts as a conduit for sound coming from the tenants space.

My idea for solving this problem is adding a second zone in the apartment through an entirely different system and seal the ducts downstairs and patch the soffit. Would a hydronic radiator system be able to be added/installed on my gas boiler for the apartment? Thanks

    It is unclear from your post what kind of system you have.
    It sounds like you have a gas forced air furnace. Do you have pictures?

    Sure why not and while your at it add an second meter ...

    You would have to add an boiler , you can not use the hot water heater for heating the space ...

    I have enough experience to know , that I dont know it all

    How large is the space of the apartment. Maybe a couple ductless heads will work instead, especially if the lower level is 3 or 4 feet below grade.

    It’s at grade and about 700 sq ft, that’s not a bad idea. Thanks.

    What size and how many lower level diffusers? Lower return size?
    You might get short cycling on limit if you close off too much air flow. How old is the furnace? What make and size?
    Is the furnace also serving an A/C system?
