Heat Pump Payback in Portage, IN
Is a heat pump worth it in Portage?
Here in Portage, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Portage would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $109 a year here, so the extra spend stays unrecovered. There's no spin on that: Portage's numbers say wait.

The climate behind Portage's payback figure
Degree days tell the story here: Portage racks up 4617 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 859 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 1.6°F here (coldest 2024 reading -7.2°F), which works out to a seasonal COP of 2.74 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Portage sits firmly in cold-climate territory, so that's the class of unit priced here.

Portage's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,267 heating kilowatt-hours annually on top of cooling, totalling about $851 a year on electricity. That compares with roughly 48 Mcf a year of gas at Portage's $11.49 per-Mcf rate, about $742 a year with the old AC included, against a local electricity rate of 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 $7,139 behind.
The break-even point in Portage
The heat pump would become the cheaper option in Portage if electricity fell to 14.2¢/kWh (from 17.03¢) or gas rose above $13.76 per Mcf (from $11.49). At today's prices a cheaper quote cannot rescue the gas comparison in Portage, since there is no yearly saving to recover it from.
Electric resistance heat in Portage, compared
Not every home in Portage has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,329 a year, which recovers the extra $10,000 spent going electric in roughly 7.5 years.
Portage against the rest of the country
Portage lands at position 1070 out of 3206 cities on heating severity (coldest is 1), and 1073 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Portage
About 38,576 people live in Portage, Indiana, 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.
Where Portage's figure comes from
The methodology guide walks through exactly how Portage's 2.74 seasonal COP and the rest of this page's numbers get built. Portage's 1.6°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.
