Heat Pump costs $5,584 to $13,198 installed in New Hampshire in 2026. For an average 1,800 sq ft home, that puts the installed total at $5,584 – $13,198, with most projects landing near $9,391. New Hampshire is about 2% above the national average.
Why New Hampshire prices differ from the national average
Roughly 38% of the installed cost of heat pump is labor, and labor is the part of the bill that actually moves between states. New Hampshire construction wages average $38.45 per hour against a national figure near $36.97 — a wage index of 1.04×.
Materials behave differently. Condensers, air handlers, coils, and refrigerant lines are priced by national equipment manufacturers, so the hardware itself costs much the same in every state. That is why we apply the wage index only to the labor share and hold materials at national prices. Doing that puts New Hampshire at $5,584 to $13,198 installed, against a national baseline of $5,500 to $13,000.
Two other forces sit on top of that. Metro areas inside New Hampshire price above the statewide figure because of wages, permitting, and site access. And the local climate drives equipment sizing, and capacity requirements move the hardware cost more than labor rates do.
Heat Pump cost by project size in New Hampshire
These figures apply the New Hampshire rate to common project sizes. They cover a standard specification with normal site access.
| Home size | New Hampshire cost range | Typical |
|---|---|---|
| Small home (~1,000 sq ft) | $4,188 – $9,898 | $7,043 |
| Average home (~1,800 sq ft) | $5,584 – $13,198 | $9,391 |
| Large home (~2,600 sq ft) | $7,538 – $17,817 | $12,677 |
| Very large home (~3,500 sq ft) | $9,492 – $22,436 | $15,964 |
Where the money actually goes
For an average 1,800 sq ft home in New Hampshire at roughly $9,391, a typical bill splits like this:
| Line item | Share | Cost |
|---|---|---|
| Labor | 38% | $3,568 |
| Materials | 47% | $4,367 |
| Site prep & equipment | 9% | $873 |
| Overhead, disposal & finishing | 6% | $582 |
The labor share is why identical projects diverge so sharply between states. It is also why a bid that comes in far below these numbers usually means a thinner specification or a crew cutting site prep, not a genuine bargain.
Heat Pump cost by city in New Hampshire
Statewide averages hide a lot. Manchester, Nashua, Concord all price above the New Hampshire average, while rural counties run below it:
| Area | Cost installed | An average 1,800 sq ft home | vs state |
|---|---|---|---|
| Manchester | $5,974 – $14,121 | $10,048 | +7% |
| Nashua | $6,086 – $14,385 | $10,236 | +9% |
| Concord | $5,751 – $13,594 | $9,672 | +3% |
| Rural New Hampshire | $5,193 – $12,274 | $8,733 | −7% |
What is included in a New Hampshire quote — and what is not
A complete quote for this work should list dimensions, specification and grade, site preparation, materials, labor, cleanup, and disposal. Those are the items already reflected in the ranges above.
Costs that usually sit outside the headline number: permits (around $450 in New Hampshire), demolition or removal of existing work, unusual site access, drainage or grading corrections, and any upgrade to the standard specification. When two bids differ by thousands, the gap is nearly always one of these, not the labor rate.

Permits in New Hampshire
A residential permit for work of this type and value in New Hampshire typically runs around $450, though the figure varies by municipality and often scales with declared project value. Permit cost is rarely folded into a contractor’s per-system quote, so add it separately when comparing bids. Confirm requirements with your local building department before work begins — unpermitted work can surface later during a sale or insurance claim.
Best time of year to schedule in New Hampshire
Weather closes the working window in New Hampshire. Concrete and exterior work generally run from late spring through early autumn, and crews book out well before then. Cold-weather work is possible with blankets, heated enclosures, or accelerating admixtures, but those add cost. Booking in late winter for spring work usually secures better pricing than calling in June.
DIY versus hiring a contractor in New Hampshire
Materials account for roughly 62% of the installed price, so an average 1,800 sq ft home carries about $5,822 in materials against an installed cost near $9,391. The gap is labor, equipment, and the risk of getting it wrong.
Because New Hampshire labor runs at 1.04× the national rate, the DIY saving here is closer to the national norm. Weigh it against tool rental, waste disposal, permit responsibility, and the fact that remedial work almost always costs more than doing it right the first time.
How New Hampshire compares with nearby states

Frequently asked questions
How much does heat pump cost in New Hampshire?
In 2026, heat pump costs $5,584 to $13,198 installed in New Hampshire. For an average 1,800 sq ft home, the installed total typically lands between $5,584 and $13,198, with most projects near $9,391.
Is heat pump more expensive in New Hampshire than the national average?
New Hampshire is about 2% above the national average. The driver is a construction wage index of 1.04 times the national figure, applied to the roughly 38% of the project cost that is labor.
Which parts of New Hampshire are most expensive?
Manchester, Nashua, and Concord price above the statewide average because of higher wages, stricter permitting, and tighter site access. Rural counties typically run around 7% below the state figure.
Do I need a permit in New Hampshire?
Most municipalities in New Hampshire require a permit for work of this type and value. Budget around $450 and confirm with your local building department before work starts, since requirements vary between cities and counties.
What climate zone is New Hampshire, and how does it affect sizing?
New Hampshire sits in a cold climate zone, so heating load drives equipment sizing more than cooling load. Systems here need genuine winter capacity, and a heat pump generally needs either a cold-climate rating or a backup heat source. Expect equipment selection, not labor, to be the biggest single cost decision. New Hampshire sits in IECC zone 6-7 (cold).
When is the cheapest time to book this work in New Hampshire?
Weather closes the working window in New Hampshire. Concrete and exterior work generally run from late spring through early autumn, and crews book out well before then. Cold-weather work is possible with blankets, heated enclosures, or accelerating admixtures, but those add cost. Booking in late winter for spring work usually secures better pricing than calling in June.
How much of the cost is labor versus materials?
Labor is about 38% of the installed price and materials about 62%. That split is why state wage differences move the total so much, and why material price swings move it less than people expect.
Why do contractor quotes in New Hampshire vary so much?
Three things move a quote most: metro versus rural location, site access and preparation, and the specification itself. Two bids are only comparable when both list the same dimensions, the same grade of material, and the same scope of prep work.
