Heat pump installation in New Hampshire is a heating project that also cools, not a central air conditioner with a marketing name. Call (603) 420-0791 with your ZIP code, your current fuel, and whether you want the heat pump to carry the whole house or to sit beside the furnace or boiler you already have. An independent contractor quotes the work after a load calculation and a look at the electrical panel. Confirm license and insurance. This site does not design the system and does not file rebates for you.
Cold-climate air-source heat pumps are built to keep producing heat at temperatures common in a New Hampshire January. Capacity still falls as outdoor temperature falls. A house in Berlin or Littleton is not the same design problem as a house in Portsmouth. Ask the contractor for the unit's capacity at the design temperature they are using, not only the nameplate rating at 47°F. If the heat pump cannot carry the house on the coldest nights, the honest designs are a larger system, a cold-climate ductless layout that still has backup, or dual fuel: the heat pump runs most hours and the furnace or boiler covers the peak. Dual fuel is a control strategy. The thermostat has to know when to call the backup. That wiring is part of the quote, not an extra surprise.
Ducted, ductless, and the building
A ducted heat pump uses the furnace air handler or replaces it. Leaky, undersized ducts in older New Hampshire homes will disappoint you. A ductless system, covered on its own page, heats rooms with indoor heads and no ductwork. Many houses end up with a mix: a ducted system for the main floor and a head for a finished attic or an addition. Ask which rooms will still be cold, and ask it before you sign.
Electrical service matters. Heat pumps draw more power in heating mode than a straight air conditioner. Older panels in mill-era houses and 1950s ranches sometimes need a subpanel or a service upgrade. That work is often an electrician's license, not a gas fitter's. The quote should name who does it.
Rebates are not the installed price
NHSaves, the program run with Eversource, Liberty, Unitil, and the New Hampshire Electric Cooperative, publishes heat pump rebates. Reviewed on 2026-09-30, the residential page at nhsaves.com listed $250 per ton for customers switching from oil, natural gas, or propane, with a described limit of 5 tons per account, and a higher per-ton amount when a qualifying heat pump replaces electric-resistance heat, with pre-verification. A May 29, 2026 NHSaves note said utility customers may receive up to $2,000 per ton when switching from electric resistance. Amounts, dates, and efficiency lists change. Read the page, and the qualified product list it points to, before you subtract a rebate from a quote. This site does not promise that you qualify.
Typical cost factors
We are not publishing an installed-cost range. Third-party blogs quote wide dollar bands that we cannot tie to a New Hampshire invoice. What actually moves the quote: duct repairs, electrical upgrades, number of indoor heads, line-set length, a new pad or wall bracket, backup heat, and whether oil tank removal is included. Ask for those lines in writing. See what a heat pump costs and winter performance.
The contractor quotes the price after they assess the house. You confirm license and insurance. People in photos are actors or models.
Commissioning is part of installation
A heat pump that is hung on the wall and powered on is not commissioned. Ask the contractor to confirm charge by the method the manufacturer specifies, to set the backup balance point in front of you, and to show you how defrost sounds so you do not call it a failure on the first cold night. Ask them to write the filter sizes and the head locations on the invoice. Ask what the emergency heat switch does and when you should touch it. Homeowners who flip that switch in October and leave it there buy a winter of resistance heat and then blame the heat pump.
If the project includes an old oil tank, ask whether abandonment or removal is in the quote and what the fire department or the town expects. That is local, and it is not a detail this website can answer for every town. The contractor should. You should see it in writing before you assume the yard is part of the price.
