Upgrading HVAC System in Multifamily

[Matthew Platon]

Hello everyone, 

Wanted to know some of your thoughts on this situation I have.  I'm considering upgrading the HVAC system I have in my multifamily. I currently have radiant heat and it's a one zone system. But I'm curious if it's worth it to rip out the radiators and put in two separate forced air units. One for my for my unit and the other for my upstairs unit. Would like some feedback from anyone that has been through this or something very similar. Thank you in advance for your responses!
