Heat Pump Payback in Greenwood, IN
Heat pump vs. gas furnace in Greenwood, IN
In Greenwood, a heat pump would cost more to run each year than what you have now. $5,500 is what Greenwood would pay extra to go electric rather than replace the furnace and AC with the same again. The heat pump would cost about $80 more a year to run than the furnace it replaces, a premium with no payback. There's no spin on that: Greenwood's numbers say wait.

The climate behind Greenwood's payback figure
Greenwood has a real but manageable winter, 4285 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1278 cooling degree days. Sizing runs off the design temperature, not the average day: -0.9°F here (coldest 2024 reading -6°F), which works out to a seasonal COP of 2.68 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Greenwood, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Indianapolis International Ai, the closest NOAA station, 12.6 miles out.
Greenwood's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,049 kWh a year to keep it warm, plus cooling, for a combined electric bill near $875 a year. The gas furnace it replaces burns roughly 45 Mcf a year at $11.49 per Mcf here, for a running cost near $795 a year including the old AC (electricity here runs 17.03¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $6,703 behind.
What would change Greenwood's answer
The heat pump would become the cheaper option in Greenwood if electricity fell to 14.7¢/kWh (from 17.03¢) or gas rose above $13.29 per Mcf (from $11.49). At today's prices a cheaper quote cannot rescue the gas comparison in Greenwood, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Plenty of homes in Greenwood heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,255 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 8 years.
How Greenwood compares nationally
Ranked against the other 3206 cities covered, Greenwood comes in at 1345 for heating severity, 1 would be the coldest place in the dataset, and 572 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Where Greenwood's figure comes from
Every constant behind this page, the 2.68 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. At a -0.9°F design temperature, Greenwood sits in cold-climate territory; the guide to that class of unit explains why.
