Will a heat pump pay off in Salisbury, MD?
Salisbury technically pencils out, but only past the point the equipment would need replacing anyway. $3,500 is what Salisbury 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 $101 saved annually, for a payback of roughly 34.5 years. Salisbury's own numbers say this pencils out only in theory, not in practice.
The climate behind Salisbury's payback figure
Salisbury has a real but manageable winter — 3711 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1246 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 17.1°F, against a record low of 12°F. That puts the seasonal coefficient of performance at 3.11 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Salisbury sits firmly in cold-climate territory, so that's the class of unit priced here.

Salisbury's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,021 heating kilowatt-hours annually on top of cooling, totalling about $864 a year on electricity. That compares with roughly 39 Mcf a year of gas at Salisbury's 16.14 per-Mcf rate — about $965 a year — against a local electricity rate of 21.16¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 133.2 years, for a 15-year net position $1,980 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Salisbury — 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 $1,466 a year comes back this way, enough that the 5.5-year payback clears the $8,000 premium comfortably within the equipment's life.
How Salisbury compares nationally
Salisbury lands at position 1669 out of 3206 cities on heating severity (coldest is 1), and 1221 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

About 33,616 people live in Salisbury, 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.
Ask a local HVAC contractor for a quote before committing either way.
