Should Bel Air switch to a heat pump?
The payback math works in Bel Air on paper, past the equipment's own working life. 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 $118 of lower running costs every year, landing the payback clock at roughly 29.7 years. Bel Air's own numbers say this pencils out only in theory, not in practice.
Why Bel Air's climate drives this number
3918 heating degree days pile up here every year, so Bel Air has a real but manageable winter; the cooling side runs to 1410 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 17.6°F, against a record low of 15.8°F. That puts the seasonal coefficient of performance at 3.12 for the recommended cold-climate unit. A cold-climate unit is the right call in Bel Air — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, MARTIN STATE AIRPORT, 14.5 miles from Bel Air.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,180 kWh a year to keep it warm, plus cooling, for a combined electric bill near $927 a year. The gas furnace it replaces burns roughly 41 Mcf a year at 16.14 per Mcf here, for a running cost near $1,045 a year (electricity here runs 21.16¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 114.4 years, for a 15-year net position $1,730 behind.
Electric resistance heat in Bel Air, compared
Plenty of homes in Bel Air heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Bel Air's answer improves. Switching saves about $1,559 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 5.1 years.
How Bel Air compares nationally
Bel Air lands at position 1577 out of 3206 cities on heating severity (coldest is 1), and 3108 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
Next step for 10,395 people in Bel Air
About 10,395 people live in Bel Air, Maryland, 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.

More on how this number was built
Every constant behind this page — the 3.12 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Bel Air's 17.6°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
