Heat Pump Installation Cost Calculator
Estimate the cost to install an air-source heat pump by home size, efficiency (SEER2/HSPF2), ductwork, and backup heat. Get a materials and labor breakdown in seconds.
Project Details
Conditioned floor area. We size at roughly one ton per 600 sq ft — a rule of thumb; a Manual J load calculation is the accurate method, and right-sizing matters more for heat pumps than for AC.
HSPF2 rates heating efficiency. Cold-climate (premium) models hold capacity well below freezing and may qualify for larger rebates.
No ducts at all? A ductless mini-split is usually cheaper than retrofitting — see the mini-split calculator.
Backup heat covers the coldest days when the heat pump alone can't keep up. Dual-fuel uses a gas furnace below the balance point.

Materials
| Item | Qty | Low | Mid | High |
|---|---|---|---|---|
| Air-Source Heat Pump (3.5-ton) | 3.5 ton | $2,975 | $4,200 | $6,125 |
| Electric Strip Backup Heat | 1 unit | $100 | $300 | $500 |

| Installation Labor | 3.5 ton | $1,575 | $2,100 | $3,325 |
| Permit & Inspection | 1 job | $150 | $350 | $700 |
| Subtotal | $1,725 | $2,450 | $4,025 |
Notes
- • Sized at about 3.5 tons for 2,000 sq ft. Right-sizing matters more for heat pumps than for AC — an oversized unit short-cycles and heats poorly. A Manual J load calculation is the accurate method.
- • Standard/high-efficiency model. In a cold climate, weigh a cold-climate (premium) unit that needs less backup heat.
- • Includes electric strip backup for the coldest days; strip heat is expensive to run, so a well-sized heat pump should rarely need it.
- • May qualify for the federal Energy Efficient Home Improvement Credit (up to $2,000 for a qualifying heat pump) plus state and utility rebates — confirm current limits with a tax professional. Excludes electrical-panel upgrades and old-system removal.
About the Heat Pump Calculator
A heat pump heats and cools with one system by moving heat rather than making it, which is why it's become the default upgrade for homeowners trying to cut energy bills and electrify. What you'll pay depends on your home's size, how efficient and cold-tolerant a model you choose, whether your ductwork is usable, and what backup heat you add for the coldest days. This calculator combines the heat pump, backup heat, ductwork when needed, installation labor, and permits into a realistic low, average, and high range before you gather quotes.
How We Calculate Heat Pump Cost
We size the system from your home's square footage at roughly one ton per 600 sq ft, rounded to the nearest half-ton and capped at 5 tons. Equipment cost is a per-ton price scaled by an efficiency multiplier for the SEER2/HSPF2 tier — cold-climate variable-speed models cost the most. We add electric strip backup or dual-fuel integration depending on your choice, ductwork priced per square foot when you don't have usable ducts, per-ton installation labor, and a permit. Everything is split into materials and labor across low/average/high tiers.
Factors That Affect Heat Pump Cost
The biggest swings are efficiency tier and ductwork. A cold-climate variable-speed unit can cost well over half again as much as a standard model, and new ducts add $3,000–$8,000+. After that come system size, backup-heat choice (dual-fuel adds furnace integration), electrical-panel capacity, and local labor rates — use the Location selector to adjust for your state. Don't size on price alone: an oversized heat pump short-cycles and heats unevenly, so the Manual J load calculation matters more here than for a cooling-only AC.
Heat Pump Cost by Type
Installed cost ranges by heat-pump type. Air-source ducted is the whole-home default; ductless and geothermal serve different needs.
| Type | Installed cost | Best for | Notes |
|---|---|---|---|
| Air-source (ducted) | $4,500 – $10,000 | Whole home with ducts | Most common; uses existing ductwork |
| Ductless mini-split | $3,500 – $8,000 | No ducts, additions, zoning | Per-zone; see mini-split calculator |
| Cold-climate (variable-speed) | $7,000 – $16,000 | Cold regions | Holds capacity below freezing; bigger rebates |
| Geothermal (ground-source) | $15,000 – $35,000 | Highest efficiency, long stay | Ground loop drives cost; large tax credit |

Will a heat pump keep up in cold weather?
This is the question that stalls most heat-pump decisions, and the honest answer is: a modern one will, if you size and spec it right. Older single-speed heat pumps did lose their breath near freezing and lean hard on expensive electric strip heat. Today's variable-speed cold-climate models are a different animal — many hold most of their rated capacity at 5°F and keep producing heat well below zero.
Two numbers tell the story: HSPF2 (seasonal heating efficiency) and the capacity rating at low temperature, which a good contractor will show you. The point where the heat pump can no longer meet the home's heat loss on its own is the balance point; below it, backup heat fills the gap. In a cold climate, a cold-climate model plus a sensible backup — electric strip for mild regions, a dual-fuel gas furnace for harsh ones — gives you efficient heating most of the winter and a safety net for the coldest snaps.
Heat pump vs. furnace + AC: which costs less?
Up front, a heat pump and a furnace-plus-AC system land in a similar range when you already have ducts — the heat pump replaces both the AC condenser and the furnace's heating job with one outdoor unit. Where a heat pump pulls ahead is operating cost and incentives: it can deliver several units of heat per unit of electricity, and the federal tax credit for a qualifying heat pump (up to $2,000) is more than triple the central-AC cap, with utility rebates often stacked on top.
The case for keeping a furnace is a cold climate with cheap natural gas — there, a dual-fuel setup pairs a heat pump for mild weather with the furnace for deep cold, capturing the best of both. If you're replacing a dead AC and your furnace is also aging, pricing a heat pump (or dual-fuel) instead of a like-for-like AC is almost always worth doing before you sign.
Heat Pump Cost by Home Size

| 2,000 sq ft | $4,800 | $6,950 | $10,650 |
| 2,500 sq ft | $5,450 | $7,850 | $12,000 |
| 3,000 sq ft | $6,750 | $9,650 | $14,700 |
