Does anyone have any experience with mini-splits?

1. They're probably the best option for retrofitting into a house without ductwork

which will be my problem in this house. The pros are that you can use the AC in the area you're occupying and turn it on in bedrooms just before you go to bed, saving money. The ones I've seen aren't terribly noisy.

The cons are having a large unit up on the wall, something a lot of people don't like, especially in rooms with lower ceilings.

The hospital near me has them in some of the waiting rooms and they seem to work just fine.
