A heat pump heats and cools with one machine. Air-source units are the most common; ductless mini-splits suit homes without ducts; geothermal costs the most up front but draws heat from the ground.

What affects the price
- Type (see the table) and capacity.
- Cold-climate models cost more but keep heating in deep cold.
- Ducts: a mini-split avoids ductwork; a ducted system may need repairs.
Ways to pay less
- Ask your utility and state about heat pump rebates; the federal 25C credit ended after 2025.
- Get a load calculation before choosing a size.
