Is a heat pump worth it in Anchorage?
Anchorage is a place where a heat pump genuinely costs more to operate than the alternative. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). The heat pump would cost about $1,630 more a year to run than the furnace it replaces — a premium with no payback. That's Anchorage's own climate and rates talking, not a hedge or a caveat.
Anchorage's weather, in the numbers that matter
Anchorage has one of the harshest winters in the country — 10275 heating degree days a year against a 65°F base — and summers rarely ask much of an air conditioner, at 6 cooling degree days. Sizing runs off the design temperature, not the average day: -30.1°F here (record low -32.6°F), which works out to a seasonal COP of 2.3 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Anchorage — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from BRYANT ARMY AIRFIELD HELIPORT, the closest NOAA station, 13.8 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 11,312 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $3,019 a year. That compares with roughly 107 Mcf a year of gas at Anchorage's 12.96 per-Mcf rate — about $1,389 a year — against a local electricity rate of 26.68¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $27,957 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Anchorage 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. About $3,924 a year comes back this way, enough that the 2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Anchorage ranks in this dataset
Among 3206 cities, Anchorage's winter puts it at rank 4 for severity, while its size puts it at rank 75 for population — 1 in both cases being the extreme. 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 Anchorage
Anchorage, Alaska is home to about 289,600 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Anchorage, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page — the 2.3 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a -30.1°F design temperature, Anchorage sits in cold-climate territory; the guide to that class of unit explains why.
