Every mini-split is a heat pump, so the real question is ducted or ductless. A ducted heat pump moves air through your existing ductwork from one indoor air handler. A ductless mini-split delivers air straight from wall or ceiling units in each space.
Price
Aarvaks heat pump installation starts at $17,000 for a single-zone ducted system. Ductless mini-splits start at $6,500 for a single zone. Whole-home costs depend on the number of zones and the condition of your ducts.
Which Fits Your Home
- Good ducts, central system today: a ducted heat pump replaces the furnace and AC and uses the existing vents.
- No ducts or failing ducts: a ductless mini-split avoids new ductwork.
- Rooms at different temperatures: ductless zones give each room its own control.
- Hidden equipment preferred: a ducted system keeps indoor equipment out of sight.
Comfort and Efficiency
Ducted systems lose some energy through ductwork, especially in attics and crawl spaces. Ductless systems avoid duct losses and let you heat or cool only the rooms in use. A ducted system spreads air more evenly through a whole house from fewer pieces of equipment.
