Split unit vs central air question

My wife and I recently purchased a large, ranch style house. Unfortunately, the AC system is shot. Actually, there are two systems, one in the basement for that massive space, and then the other for the rest of the house.

The house itself is wall to wall tile throughout. Since it's just the two of us for now, my wife and I were considering installing a split unit for the master bedroom and then using a dehumidifier for the large basement.

Google seems to have lots of information on where to buy one of these and some on how to install one, but not much on their efficiency when compared to central air units. Has anyone got experience with these? We did some math and it looks like w/lighting and AC the power bill would be about $425. We'd like to get it down as much as we can, would one of these units help?

wow that is expensive! What is your electric rate and how big of a ranch home do you have!? A mini split would be ok for your bedroom, efficiency varies based on what you purchase. I would recommend a new central a/c if you pan to live there for any length of time.

Big. About 4k square feet. However, it's a long, linear house and the previous owners added a second floor addition with 2 bedrooms and a jack/jill bathroom above one section.

I don't live in Georgia but I don't need AC in the basement, I just run a dehumidifier down there.

Any recommendations on a dehumidifier? There's already one in the basement. Should I get another?

If you're in the market for a dehumidifier, one thing to remember is that the bigger units are actually more efficient.
