How much does a heat pump cost?

Installed: ducted air-source: $4,000-$10,000. Mini-split (single zone): $1,500-$4,000. Mini-split (multi-zone): $5,000-$12,000. Geothermal: $15,000-$30,000+. Dual fuel: $5,000-$12,000. National average: $5,500-$8,000 (ducted air-source). Tax credit: 30% federal (through 2032). IRA rebates: up to $8,000 (income-qualified). After incentives: a $7,000 heat pump could cost $4,000-$5,000.

Do heat pumps work in cold climates?

Yes. Modern cold-climate heat pumps work efficiently down to -5 to -15 degrees F. Brands: Mitsubishi Hyper-Heating, Daikin, Fujitsu, Bosch. At extreme cold: efficiency drops (but they still work). Below their rated temperature: they use backup heat (electric resistance or gas furnace). Dual fuel option: heat pump + gas furnace. Heat pump handles 80-90% of heating hours. Furnace kicks in during the coldest days. This is the most cost-effective setup for very cold climates. Reality: most of the US can use heat pumps as the primary heating source. Even in Minnesota and Maine, cold-climate heat pumps handle the vast majority of heating hours.

Heat pump vs furnace vs AC?

Heat pump: one system for heating AND cooling. 2-4x more efficient than resistance heating. Qualifies for tax credits. Lower operating cost. Works best in moderate climates (but cold-climate models are improving). Cost: $4,000-$10,000. Furnace + AC: two separate systems. Gas furnace is reliable in extreme cold. AC handles summer cooling. Higher operating cost. More proven in extreme cold. Cost: $5,000-$12,000 (combined). Recommendation: for most of the US, a heat pump is the best value when you factor in operating savings and tax credits. For very cold climates, consider a dual fuel system (heat pump + gas furnace backup).

How long does a heat pump last?

Air-source: 15-20 years. Mini-split: 20+ years. Geothermal (indoor unit): 25+ years. Geothermal (ground loop): 50+ years. Factors: maintenance (regular filter changes and annual tune-ups). Quality of installation. Usage (heating-dominant climates work the system harder). Climate. Maintenance: change filters every 1-3 months. Annual professional tune-up. Keep outdoor unit clear of debris, snow, and ice. Check defrost cycle in winter. Clean or replace indoor air handler filter. A well-maintained heat pump can exceed 20 years.

How Heat Pumps Work

The basics: A heat pump moves heat rather than generating it. In summer: moves heat OUT of your house (like an AC). In winter: moves heat INTO your house (reverses the cycle). Uses refrigerant and a compressor (same technology as a refrigerator). 2-4x more efficient than resistance heating.

Efficiency explained: A gas furnace at 95% AFUE: produces 0.95 BTU of heat per BTU of fuel. A heat pump at COP 3.0: produces 3.0 BTU of heat per 1 BTU of electricity. This means a heat pump is roughly 300% efficient in moderate conditions. Efficiency decreases as outdoor temperature drops. Modern cold-climate heat pumps maintain efficiency down to -5°F to -15°F.

Types

Air-source (ducted): Most common. Works with existing ductwork. Replaces both furnace and AC. Cost: $4,000-$10,000 (installed). Best for homes with existing ducts.

Mini-split (ductless air-source): No ductwork needed. Individual indoor units per zone. Cost: $1,500-$4,000 (single zone), $5,000-$12,000 (multi-zone). Best for homes without ducts, additions, and zone control.

Geothermal (ground-source): Uses stable ground temperature. Most efficient (400-600% effective efficiency). Cost: $15,000-$30,000+. Ground loop lasts 50+ years. Best for new construction or where long-term savings justify the cost.

Dual fuel: Heat pump + gas furnace backup. Heat pump handles moderate temps. Furnace kicks in during extreme cold. Cost: $5,000-$12,000. Best for cold climates where a heat pump alone may struggle.

Cost

Installed cost: Ducted air-source: $4,000-$10,000. Mini-split (single zone): $1,500-$4,000. Mini-split (3-4 zones): $5,000-$12,000. Geothermal: $15,000-$30,000+. Dual fuel: $5,000-$12,000.

Operating cost per year: Air-source heat pump: $800-$2,000. Geothermal: $500-$1,500. Compared to: gas furnace + AC: $1,500-$3,000. Electric furnace + AC: $2,000-$4,000.

Tax credits and rebates: Federal tax credit: 30% of cost (through 2032) for heat pumps. IRA rebates: up to $8,000 for heat pumps (income-qualified). State and utility rebates: vary. Total potential savings: $2,000-$10,000+ in credits and rebates.

Payback period: Air-source (replacing gas + AC): 5-10 years. Air-source (replacing electric heating): 3-5 years. Geothermal: 7-15 years.
