As the name implies, ductless mini-split systems don't need a full air duct system to deliver cooled or heated air from the air handler to the rooms of your home. Instead, ductless splits are mounted to walls and consist of an outdoor condenser unit and one or more indoor units that hold the air handler and blowers to help circulate the air.

Unlike conventional systems that spread air throughout the home via large air ducts, ductless mini-splits are designed for single rooms and use an individual fan and evaporator unit.

The process of installing ductless mini-splits involves making electrical connections and cutting the refrigerant line. That's why when you're ready to install a ductless mini-split system, it's important not to get overly eager. It's not worth the risk of damaging your walls, botching the entire job, or hurting yourself. Instead, contact your local HVAC company for professional guidance and installation.
