Is a heat pump worth it in Johnstown?
Here in Johnstown, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Johnstown 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. Running costs here land $92 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Johnstown's numbers say wait.
The climate behind Johnstown's payback figure
Degree days tell the story here: Johnstown racks up 5504 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 584 cooling degree days on the cooling side. 7°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 3°F on file. Worked through the model, that's a seasonal COP of 2.87 on the cold-climate unit fit for this climate. Johnstown needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from J MURTHA JTWN-CMBRA CO APT, the closest NOAA station, 4.5 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,856 heating kilowatt-hours annually on top of cooling, totalling about $1,111 a year on electricity. The gas furnace it replaces burns roughly 57 Mcf a year at 15.04 per Mcf here, for a running cost near $1,019 a year (electricity here runs 20.75¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $4,877 behind.
The other scenario: no gas furnace to begin with
Not every home in Johnstown has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,938 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 4.1 years.
Where Johnstown ranks in this dataset
Johnstown lands at position 377 out of 3206 cities on heating severity (coldest is 1), and 2110 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.

About 17,853 people live in Johnstown, Pennsylvania, 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.

Where Johnstown's figure comes from
Every constant behind this page — the 2.87 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 7°F design temperature, Johnstown sits in cold-climate territory; the guide to that class of unit explains why.
