Heat Pump Cost in New Hampshire 2026
A whole-home ducted heat pump costs $7,030-$11,580 installed in New Hampshire in 2026, and a cold-climate ducted system runs $9,170-$15,760. That price lands in a state where the heating bill is the argument for the machine: about 42% of New Hampshire homes burn heating oil as their main fuel, and oil cost $6.06 a gallon in the first week of November 2026, up $2.56 in a year. Electricity is expensive here too — about 27 cents a kilowatt-hour — so a heat pump only wins if it is a true cold-climate unit that keeps its efficiency at 5 degrees and below, sized to the house with a Manual J calculation and backed by the oil or propane system it replaces. This guide prices every system from a single mini-split head to geothermal, compares Manchester with Nashua and Concord, works the oil-versus-electricity sums at four different seasonal efficiencies, and is blunt about the money that is not here: the federal tax credit is $0, the $8,000 HEAR rebate has not launched, and even when it does, a fuel switch from oil will probably not qualify. What is here is NHSaves at $250 a ton, $2,000 a ton for homes leaving electric resistance heat, and a $650 regional discount that stacks on top.
