Quick answerQuick answer: Installing an air-source heat pump costs $1,300 to $20,000, averaging around $6,087. A single-zone ductless mini-split starts near $1,300, a standard ducted system runs $3,500-$8,800 by tonnage, and a cold-climate or premium system can reach $20,000.
  • Air-source heat pump installation costs $1,300 to $20,000, averaging around $6,087 nationally (HomeAdvisor, Bob Vila).
  • A single-zone ductless mini-split runs $1,300 to $8,000 installed — usually cheaper than adding ductwork for a central system (HomeAdvisor, Bob Vila).
  • A cold-climate or premium high-efficiency central system costs $12,000 to $20,000 installed, versus $8,000 to $15,000 for a typical central system (HomeGuide, This Old House).
  • HomeAdvisor and Bob Vila describe a 30% federal tax credit up to $2,000 for air-source heat pumps installed 2023-2032, but the IRS confirms that credit ended for equipment placed in service after December 31, 2025 — it does not apply to a heat pump installed in 2026.

What affects the cost?

  • Ducted vs. ductless — a single-zone ductless mini-split runs $1,300-$8,000 installed versus $4,500-$8,000 for a standard ducted air-source system, since ductless skips the cost of ductwork (HomeAdvisor)
  • Tonnage/capacity — installed cost climbs from $3,500-$5,500 for a 2-ton unit to $4,500-$8,800 for a 5-ton unit as the square footage it needs to condition grows (HomeAdvisor)
  • SEER efficiency tier — equipment cost alone jumps from $1,600-$5,900 at 14-15 SEER to $3,600-$9,500 at 20+ SEER, nearly doubling for a more efficient unit of the same type (HomeAdvisor, Bob Vila)
  • Cold-climate/premium models — a premium high-efficiency central system built to hold output in cold weather runs $12,000-$20,000 installed, well above the $8,000-$15,000 typical whole-house central system (HomeGuide, This Old House)
  • Replacing a furnace + AC with one heat pump — a whole-house central heat pump ($8,000-$15,000) can come in near or under the combined cost of separate furnace ($4,800 average) and central AC ($5,000-$12,000) replacement, since one outdoor unit and one indoor air handler do both jobs (HomeGuide)
  • Labor rate — installers charge $75-$125 per hour on top of equipment cost (HomeAdvisor, Bob Vila)
  • Permits and inspections — typically $50-$300 depending on the jurisdiction (HomeAdvisor, Bob Vila)
  • Brand and equipment tier — unit-only pricing spans from budget brands like Goodman ($2,000-$8,000) to premium brands like Trane ($3,500-$15,600) and Mitsubishi ($1,700-$11,200) (This Old House, Bob Vila)
  • Real contractor bids can run lower than published national averages — Thumbtack's marketplace data puts the national average around $3,414, with a $1,430-$7,778 typical spread across all heat pump types and sizes

How much does heat pump installation cost?

An air-source heat pump costs $1,300 to $20,000 installed, averaging around $6,087 nationally, with a typical single-system range of $4,237 to $7,943 (HomeAdvisor). Bob Vila’s figures land almost identically — average $5,947, typical range $4,206 to $7,688 — likely reflecting a similar blended dataset across ductless and ducted systems. The low end covers a single-zone ductless mini-split installation at $1,300 to $8,000 (HomeAdvisor, Bob Vila); the high end covers a large, cold-climate, or premium-efficiency central system that can reach $20,000 (HomeGuide). HomeGuide and This Old House, which price a whole-house central (ducted) system specifically rather than blending in cheaper mini-splits, report higher averages of $8,350 and $8,000-$15,000. Real contractor bids can also run lower than published estimates — Thumbtack’s marketplace data puts the typical price around $3,414, with a $1,430-$7,778 spread across all heat pump types and sizes.

Does system size, ducted vs. ductless, or SEER2/HSPF rating change the price?

All three move the number substantially. By tonnage, a 2-ton system sized for roughly 1,000 sq ft runs $3,500 to $5,500 installed, climbing to $3,900-$6,200 at 3 tons (about 1,800 sq ft) and $4,500-$8,800 at 5 tons (about 3,500 sq ft) — bigger homes need more capacity, and more capacity costs more (HomeAdvisor). Ducted vs. ductless is its own factor: a ducted system ties into (or requires installing) a duct network, while a ductless mini-split runs refrigerant lines to one or more wall- or ceiling-mounted indoor units instead, which is why single-zone ductless installs start as low as $1,300 versus $4,500 for a standard ducted air-source system (HomeAdvisor). Efficiency rating hits equipment cost hardest: a 14-15 SEER unit runs $1,600 to $5,900, while a 20-plus SEER unit costs $3,600 to $9,500 — nearly double for the same tonnage (HomeAdvisor, Bob Vila). Homes in HVAC replacement territory (an aging full system, not just one component) should compare all-in project costs rather than equipment tables alone, since labor, ductwork condition, and permits stack on top of the unit price either way.

Is replacing a furnace and AC with a heat pump cheaper?

Often, yes. A whole-house central heat pump — one outdoor unit and one indoor air handler that both heat and cool — runs $8,000 to $15,000 installed (HomeGuide, This Old House), which can land near or under the combined cost of replacing a furnace (averaging $4,800) and a separate central AC unit ($5,000-$12,000) (HomeGuide). Consolidating two systems into one also means one set of ductwork, one thermostat, and one maintenance schedule going forward. The tradeoff is upfront system cost and, in some climates, the need for backup heat strips or a dual-fuel setup on the coldest days — a detail worth discussing with a contractor before committing, especially for a full HVAC replacement where a furnace-and-AC split system is also on the table.

What does a cold-climate heat pump cost, and is the federal tax credit still worth it?

A premium, cold-climate-rated central system — built to keep delivering heat efficiently well below freezing — runs $12,000 to $20,000 installed, compared with $8,000 to $15,000 for a typical central system (HomeGuide, This Old House). Placement matters in snowy climates, too. As Ross Trethewey, This Old House’s home technology expert, advises, homeowners should “install your heat pump near the gable end of your home rather than underneath a roof slope” to keep snow sliding off a roof from burying the outdoor unit. On cost offsets: HomeAdvisor and Bob Vila both cite a 30% federal tax credit for air-source heat pumps installed between 2023 and 2032, capped at $2,000, with a separate 30% credit for geothermal systems through 2033 — but neither is current. The IRS confirms both credits ended for equipment placed in service after December 31, 2025. Air-source heat pumps fall under the Energy Efficient Home Improvement Credit, which the IRS says “applies to improvements made through December 31, 2025.” Geothermal heat pumps fall under the separate Residential Clean Energy Credit, which the IRS states “is not available for any property placed in service after December 31, 2025.” A heat pump of either type installed in 2026 does not qualify for a federal credit. Confirm current eligibility with a tax professional or contractor before counting on either credit in your budget.

Prices vary by region, home size, and the specific ducted-vs-ductless and efficiency choices you make, so treat the figures above as a planning budget. Get two or three local HVAC contractor quotes, based on a proper load calculation rather than square footage alone, before committing to a final number.

Frequently asked questions

How much does it cost to install a heat pump?
Air-source heat pump installation costs $1,300 to $20,000, averaging around $6,087 nationally (HomeAdvisor, Bob Vila). Most standard single-system installs land in a narrower $4,237-$7,943 typical range (HomeAdvisor).
Is a ductless mini-split cheaper than a ducted heat pump?
Yes. A single-zone ductless mini-split runs $1,300 to $8,000 installed, while a standard ducted air-source system costs $4,500 to $8,000 (HomeAdvisor, Bob Vila) — ductless skips the cost of installing or modifying ductwork.
How much does tonnage (system size) affect heat pump cost?
A 2-ton system for a roughly 1,000 sq ft home runs $3,500 to $5,500 installed, while a 5-ton system for about 3,500 sq ft costs $4,500 to $8,800 (HomeAdvisor).
Does a higher SEER2 or HSPF rating cost more?
Yes, substantially. Equipment priced at 14-15 SEER runs $1,600 to $5,900, versus $3,600 to $9,500 at 20+ SEER (HomeAdvisor, Bob Vila) — nearly double for a more efficient unit of the same type.
What does a cold-climate heat pump cost?
A premium, cold-climate-rated central system runs $12,000 to $20,000 installed, compared with $8,000 to $15,000 for a typical central system (HomeGuide, This Old House).
Is replacing a furnace and AC with a heat pump cheaper?
Often, yes. A whole-house central heat pump runs $8,000 to $15,000 installed (HomeGuide, This Old House), which can come in near or under the combined cost of a separate furnace (averaging $4,800) and central AC ($5,000-$12,000) (HomeGuide).
Is there still a federal tax credit for heat pumps?
No, not for a heat pump installed in 2026. HomeAdvisor and Bob Vila both still describe a 30% federal tax credit for air-source heat pumps installed 2023-2032, capped at $2,000, and a 30% geothermal credit through 2033 — but the IRS confirms both credits ended for property placed in service after December 31, 2025. Air-source heat pumps fall under the Energy Efficient Home Improvement Credit, which 'applies to improvements made through December 31, 2025' (IRS); geothermal heat pumps fall under the Residential Clean Energy Credit, which 'is not available for any property placed in service after December 31, 2025' (IRS). Confirm current eligibility with a tax professional before budgeting for either.
Why do heat pump cost estimates vary so much between sources?
HomeAdvisor and Bob Vila cluster around a $6,000 average for a blended mix of system types, while HomeGuide and This Old House report $8,000-$15,000 for a whole-house central system specifically. Thumbtack's real marketplace bids average lower, around $3,414, reflecting a wider mix of small and large jobs.

HomeAdvisor and Bob Vila cluster closely on a blended national average across all air-source configurations: $6,087 (range $4,237-$7,943) and $5,947 (range $4,206-$7,688) respectively — likely reflecting similar underlying datasets. HomeGuide and This Old House report notably higher figures because they price a whole-house central (ducted) system specifically rather than blending in cheaper mini-splits: $8,350 average / $5,000-$15,000 range (HomeGuide) and $8,000-$15,000 for a central system (This Old House). Thumbtack's marketplace-quote data is lower still on average ($3,414 typical, $1,430-$7,778 range) but has a wider tail at both ends ($422 low to $23,217 high), consistent with it aggregating real bids across everything from small ductless add-ons to large multi-zone jobs rather than a single 'typical' project. national_average_usd ($6,087) and project_low/high_usd ($4,237-$7,943) are anchored to the HomeAdvisor/Bob Vila cluster, which best represents a typical single-system air-source replacement. range_low_usd ($1,300) reflects the low end of a single-zone ductless mini-split (HomeAdvisor, Bob Vila), and range_high_usd ($20,000) reflects the high end of a premium or cold-climate central system (HomeGuide), giving the full realistic span from a small ductless add-on to a large, high-efficiency whole-house install. by_type breaks the job out by ducted tonnage tier (2-ton, 3-ton, 5-ton, installed), by system class (ductless single zone, whole-house central, cold-climate/premium central), and by SEER efficiency tier (equipment only, not installed — HomeAdvisor's and Bob Vila's SEER tables price the unit alone, separate from their tonnage tables which are installed cost). Figures generally include equipment and standard installation labor; ductwork beyond incidental hookups, electrical upgrades, permits, and smart thermostats are commonly quoted as separate line items. On incentives: HomeAdvisor and Bob Vila both cite a 30% federal tax credit for air-source heat pumps installed 2023-2032 (capped at $2,000 per HomeAdvisor), and a 30% credit for geothermal installed 2021-2033 (through Dec. 2033 per HomeAdvisor) — but that is stale. Air-source heat pumps fall under the Energy Efficient Home Improvement Credit (26 U.S.C. 25C); the IRS states that credit covers 'improvements made through December 31, 2025' and 'qualifying property placed in service on or after Jan. 1, 2023, and before December 31, 2025' (IRS, reviewed 28-Apr-2026). Geothermal heat pumps instead fall under the Residential Clean Energy Credit (25D), which the IRS states 'is not available for any property placed in service after December 31, 2025' (IRS, reviewed 04-Jul-2026). Both credits, in other words, ended for equipment placed in service in 2026 — neither the $2,000 air-source credit nor the 30% geothermal credit applies to a heat pump installed this year, regardless of what HomeAdvisor's and Bob Vila's pages still say. Homeowners should confirm current eligibility with a tax professional before budgeting for either credit.
