Heat Pump Payback in New Carrollton, MD
Will a heat pump pay off in New Carrollton, MD?
The payback math works in New Carrollton on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. New Carrollton's residents would see roughly $119 a year back in running costs, putting the payback around 46.4 years. That's a technicality, not a recommendation, for anyone actually living in New Carrollton.

How cold New Carrollton actually gets
3720 heating degree days pile up here every year, so New Carrollton has a real but manageable winter; the cooling side runs to 1541 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 14.9°F, and the coldest daily reading in the 2024 station record was 12.9°F. That puts the seasonal coefficient of performance at 3.06 for the recommended cold-climate unit. A cold-climate unit is the right call in New Carrollton, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

New Carrollton's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,078 kWh a year to keep it warm, plus cooling, for a combined electric bill near $929 a year. That compares with roughly 39 Mcf a year of gas at New Carrollton's $16.14 per-Mcf rate, about $1,048 a year with the old AC included, against a local electricity rate of 21.16¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $3,722 behind.
How sensitive New Carrollton's result is to prices
Gas would only overtake the heat pump in New Carrollton if electricity rose past 26.1¢/kWh from 21.16¢, or gas fell under $13.08 per Mcf from $16.14. A useful quote test for New Carrollton: the heat pump is worth it within a decade if it costs less than $1,190 more than replacing the furnace and AC, and within 7 years if the gap is under $833.
Electric resistance heat in New Carrollton, compared
Gas isn't universal in New Carrollton, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,486 a year comes back this way, enough that the 6.7-year payback clears the $10,000 premium comfortably within the equipment's life.
