Ductless heating and cooling has become very popular in recent years. Rather than functioning through a network of air ducts connected to an indoor air handler and evaporator unit, ductless heating and cooling systems break up the indoor unit and blower fans to distribute conditioned air into the various rooms of your a through mini air handlers mounted high up on the walls.
If you’ve been in a home and have seen something up on a wall that looks like a window AC but it doesn’t go back through the wall, then you’re looking at a ductless air handler. These wall-hanging units are hooked up to a single outdoor cabinet, creating a central heat pump system without ductwork.
