Heat Pump Installation Cost in the U.S.: Ductless vs Whole-Home (2026)
A heat pump costs between $3,500 and $8,000 to install for a single-zone ductless mini-split, and $8,000 to $20,000+ for a whole-home ducted or multi-zone system in the U.S. in 2026. The price per square foot drops in larger homes because the unit itself is a fixed cost.
Before requesting a quote, it helps to understand what drives the price. See also the complete heat pump guide.
What drives the price?
- Home size and layout: more square footage and more zones raise the cost.
- Ducts: reusing existing ductwork is cheaper; adding or modifying ducts adds $2,000–$6,000.
- System type: a single ductless mini-split is the cheapest entry point; whole-home ducted systems cost the most.
- Cold-climate models: ccASHP units for very cold regions cost a bit more.

Frequently asked questions
Why is it cheaper per square foot in bigger homes?
Because the heat pump unit is a fixed cost; adding area mostly increases variable costs like ducts or refrigerant lines.
Is a mini-split or a ducted system cheaper?
A single-zone mini-split is the cheapest option; ducted whole-home systems cost more but heat/cool the entire house.
How much to replace an oil furnace with a heat pump?
Typically $10,000–$18,000 for a whole-home ducted system, before incentives.
Does the price include the outdoor unit?
Yes, quoted installed prices include the outdoor unit, indoor equipment and labor.
