HeatPumpPayback

Heat pump vs. gas furnace in Indiana, PA

In Indiana, a heat pump would cost more to run each year than what you have now. 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. Running costs here land $41 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Indiana's numbers say wait.

The climate behind Indiana's payback figure

Indiana has a real but manageable winter — 4783 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 793 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 8.6°F, against a record low of 3.2°F. That puts the seasonal coefficient of performance at 2.91 for the recommended cold-climate unit. Indiana 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 INDIANA COUNTY/JIMMY STEWART, the closest NOAA station, 3 miles out.

The month-to-month numbers for Indiana

A 2000-square-foot house here would pull roughly 4,162 heating kilowatt-hours annually on top of cooling, totalling about $1,004 a year on electricity. That compares with roughly 50 Mcf a year of gas at Indiana's 15.04 per-Mcf rate — about $962 a year — against a local electricity rate of 20.75¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $4,122 behind.

The other scenario: no gas furnace to begin with

Not every home in Indiana has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $1,722 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 4.6 years.

Indiana against the rest of the country

Among 3206 cities, Indiana's winter puts it at rank 967 for severity, while its size puts it at rank 2477 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Deciding what's next in Indiana, PA

About 14,294 people live in Indiana, 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 Indiana's figure comes from

The methodology guide walks through exactly how Indiana's 2.91 seasonal COP and the rest of this page's numbers get built. Indiana's 8.6°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
