Maybe you're planning on adding on to your home or redesigning the layout of your house; either way it's important to know what kind of cooling system will best suit all needs! Mini split systems offer more flexibility with placement while central units tend provide smoother temperature fluctuations throughout homes.

Using a central air conditioner when you just want to cool/heat one or two rooms can lead to a dramatic increase in your bills. Whereas, mini-splits are designed to be room or area specific.
