There's a lot of competition for both, so we would likely theme it and modernize it.

One of my friends own a A.C company and when I purchased my last house I asked him to change my old --but functioning fine-- a.c unit (20+ yrs), he told me to hold my horses because older a.c's were made to last, and when they brake it, it is often times a simple inexpensive fix (unlikely the modern ones that are made to last 5 years and when it brakes it is better to change to a new one than fixing it).

Turned spindles don't match the modern vibe you are going for in the rest of the house.7.

I would stick to a cosmetic fixer uppers and choose a more modern look as your finished product.
