Will a heat pump pay off in Laconia, NH?
In Laconia, a heat pump would cost more to run each year than what you have now. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. The heat pump would cost about $231 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Laconia's numbers say wait.
Why Laconia's climate drives this number
6350 heating degree days pile up here every year, so Laconia has a cold winter that leans hard on heating equipment; the cooling side runs to 560 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 5°F here (record low -2°F), which works out to a seasonal COP of 2.82 for the cold-climate class of unit this climate calls for. Laconia needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. Climate figures trace to the nearest NOAA station, LACONIA MUNICIPAL AIRPORT, 2.6 miles from Laconia.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 5,702 heating kilowatt-hours annually on top of cooling, totalling about $1,656 a year on electricity. Laconia's gas rate of 18.61 per Mcf, applied to the 66 Mcf a year the furnace burns, puts its running cost near $1,425 a year, against 26.80¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $6,962 behind.
Electric resistance heat in Laconia, compared
Plenty of homes in Laconia heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $2,848 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 2.8 years.
Where Laconia ranks in this dataset
Ranked against the other 3206 cities covered, Laconia comes in at 112 for heating severity — 1 would be the coldest place in the dataset — and 2164 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Laconia
About 17,310 people live in Laconia, New Hampshire, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Where Laconia's figure comes from
Every constant behind this page — the 2.82 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 5°F design temperature, Laconia sits in cold-climate territory; the guide to that class of unit explains why.
