A heat pump’s overhead often depends on its type. The following are the average costs to expect when purchasing and installing a new heat-pumping system:

Geothermal: $13,000 to $36,000

Gas: $4,300 to $8,000

Air-Source: $3,300 to $7,500

Ductless Mini-Split System: $1,500 to $5,000

Other factors that influence the total costs of adding a heat pump include:

Size

Brand

Seasonal Energy Efficiency Ratio (SEER)

Heating Seasonal Performance Ratio (HSPF)

Professional Labor

If you’re looking at furnaces, keep in mind that these heating systems don’t usually use SEER ratings to measure their supplied heat.
