Heat pump installation prices in Nashua by material
Each row starts from the installed price per home published in a national cost guide, then moves only the labor part of that price by Nashua's labor index. For 2,000 sq ft home:
| Material | National | Nashua | Midpoint |
|---|---|---|---|
| Ducted air-source heat pump | $10,000–$20,000 | $11,000–$22,000 | $16,500 |

Permit fee in Nashua
Named in the schedule The fee schedule names this kind of work.
“Ductless split system: $40.”
“Mechanical: Nonrefundable application processing and review fee: $50.”
Applied to a 2,000 sq ft home heat pump estimated at $11,000 to $22,000, that gives $90 to $90, about 0.55% of the midpoint price. Among the 15 towns on this site whose schedules cover this work, Nashua ranks 8 from the cheapest; Fitzwilliam is lowest at $50 and Newport highest at $202.81 for its own midpoint job. The schedule names ductless split systems; a ducted system is not named separately, so the ductless line is shown for both.
Schedule: City of Nashua Code, Chapter 105 Building Construction, § 105-28 Fee Schedule (amended 3-9-2021 by Ord. O-21-045). The building department decides whether a permit is required and what valuation it accepts; the national guide puts heat pump permits at $50–$300.
Why Nashua differs from the national price
Nashua is in Hillsborough County, which the Bureau of Labor Statistics counts in the Manchester-Nashua, NH metropolitan area. The median wage there for hVAC mechanics and installers is $35.14 an hour against $29.33 nationally, so the labor part of a national price is scaled by 1.198 (+19.8%).
On this job the labor portion is $5,000 to $10,000 at national rates and $6,000 to $12,000 at Nashua rates, so the midpoint rises $1,500 above the national figure. Against the New Hampshire statewide wage it is $90 lower. Materials are priced at the national figure: shingle, lumber and equipment prices are set by distributors, not by a town.
A second published benchmark points the same way for the region: Remodeling's 2025 Cost vs Value report prices its “HVAC Conversion, Electrification” job at $19,500 nationally and $22,200 in New England. Those are fixed specification jobs, not per-square-foot prices, so they are shown for comparison only.

Before asking for quotes
- The Nashua building department can say for free whether this job needs a permit and what it will cost; the schedule linked above is its own published document.
- Written quotes that list the same scope (area, material line, removal, disposal, permit) can be compared line by line; the quote comparison guide walks through it with these numbers.
- A quote far below $11,000 or above $22,000 is not wrong in itself, but it is worth asking what it includes or leaves out.
