I have been getting questions lately on efficiency work about the pros and cons of ductless ac/heat pump systems such as the Mitsubishi Mr. Slim for use in select applications in the Dallas area.
On the surface, it seems like a good idea for some applications around here to provide conditioning for smaller areas with less power usage than traditional systems. I have even thought about it for my house in the master bedroom area.
In some brief research online I have seen some decension about these. Are there any particular downsides to the use of these systems in the southern climates?
