How Does a Ductless Mini-Split System Work?

Ductless systems have two main components:
  • A heat pump
  • Air handling units (aka “heads” or “evaporators”)

The heat pump sends heated or cooled refrigerant, depending on the season, to the wall or ceiling-mounted air handling units through refrigerant lines. The air handling unit uses the refrigerant to heat or cool the air and circulate it throughout its dedicated zone.
