Heat pump vs. gas furnace in Havre de Grace, MD
In Havre de Grace, the extra upfront cost technically comes back, just not before the equipment wears out. 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. That premium is recovered through $96 of lower running costs every year, landing the payback clock at roughly 36.4 years. That's a technicality, not a recommendation, for anyone actually living in Havre de Grace.
How cold Havre de Grace actually gets
3872 heating degree days pile up here every year, so Havre de Grace has a real but manageable winter; the cooling side runs to 1221 cooling degree days, where summers are hot enough that cooling matters as much as heating. 16.7°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12.7°F on file. Worked through the model, that's a seasonal COP of 3.1 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Havre de Grace — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Havre de Grace
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,163 kWh a year to keep it warm, plus cooling, for a combined electric bill near $890 a year. That compares with roughly 40 Mcf a year of gas at Havre de Grace's 16.14 per-Mcf rate — about $986 a year — against a local electricity rate of 21.16¢/kWh. Buy it outright, not incrementally, and payback stretches to 140.4 years; over 15 years the net position sits $2,057 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Havre de Grace — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,520 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 5.3 years.
How Havre de Grace compares nationally
Havre de Grace lands at position 1607 out of 3206 cities on heating severity (coldest is 1), and 2370 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
