Is it worthwhile for homeowners to purchase a mini-split AC in Nocatee, FL, when they already own a central AC system? A mini-split air conditioner, just like the traditional ducted heat pump, is made of three main components: air handler, compressor, and refrigerant line. The air handler draws heat out of your living space, the refrigerant line carries it to the compressor, and that unit releases the heat outside.

There are important differences, though. A mini-split cools only one room, but you can connect up to eight air handlers to a single compressor, which could equate to cooling for the entire house. The air handler itself is much smaller and more compact, and you either mount it on the wall or hang it from the ceiling. The refrigerant line is narrower, too.
