Split Air Before Reno

Was hoping to get some advice. I recently purchased a parlor level apt in a brownstone. Sometime next year I'm hoping to do a bigger renovation project, notably new bathrooms and kitchen and also potentially soundproofing some ceilings. Not planning on moving walls/structural changes. Would it be a waste to install a split air system before then, i.e. before this summer? I hate window units and would prefer to switch to split air sooner rather than later, but if it's generally better to wait and do it all at once, I guess I could live with them for another year. What do you think?
