Heat pump vs. gas furnace in Leominster, MA
In Leominster, the extra upfront cost technically comes back, just not before the equipment wears out. $3,500 is what Leominster would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $108 saved annually, for a payback of roughly 32.5 years. That's a technicality, not a recommendation, for anyone actually living in Leominster.
Leominster's weather, in the numbers that matter
Leominster has a cold winter that leans hard on heating equipment — 5524 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 824 cooling degree days. 9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 0°F on file. Worked through the model, that's a seasonal COP of 2.92 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Leominster — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Leominster's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,790 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,656 a year. The gas furnace it replaces burns roughly 58 Mcf a year at 25.06 per Mcf here, for a running cost near $1,764 a year (electricity here runs 30.15¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 125.5 years, for a 15-year net position $1,886 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Leominster heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $2,883 a year, which recovers the extra $8,000 spent going electric in roughly 2.8 years.
Leominster against the rest of the country
Ranked against the other 3206 cities covered, Leominster comes in at 356 for heating severity — 1 would be the coldest place in the dataset — and 933 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 Leominster
Leominster, Massachusetts is home to about 44,209 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 Leominster, nothing is lost by holding off until the current equipment genuinely fails.

Where Leominster's figure comes from
The methodology guide walks through exactly how Leominster's 2.92 seasonal COP and the rest of this page's numbers get built. Leominster's 9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
