What drives mini-split installation cost

  • Number of zones and indoor heads.
  • System capacity (BTU) and efficiency.
  • Length of refrigerant line runs.
  • Heat pump (heating + cooling) versus cooling only.
  • Regional labor rates.

Key cost factors

Zones drive cost

Each indoor head is its own zone with independent control. A single zone is affordable; multi-zone systems that condition several rooms cost much more.

Great for additions

Mini-splits are ideal where adding ductwork is hard, such as additions, garages, sunrooms, and older homes without ducts.
