Will a heat pump pay off in Riverdale, IL?
Riverdale is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Riverdale 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 $278 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Riverdale's numbers say wait.
Why Riverdale's climate drives this number
Degree days tell the story here: Riverdale racks up 4971 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 864 cooling degree days on the cooling side. -5.3°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -10.7°F on file. Worked through the model, that's a seasonal COP of 2.57 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Riverdale sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from LANSING MUNICIPAL AP, the closest NOAA station, 8.9 miles out.
The month-to-month numbers for Riverdale
A 2000-square-foot house here would pull roughly 4,898 heating kilowatt-hours annually on top of cooling, totalling about $1,074 a year on electricity. That compares with roughly 52 Mcf a year of gas at Riverdale's 11.25 per-Mcf rate — about $796 a year — against a local electricity rate of 19.06¢/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 $7,671 behind.
The other scenario: no gas furnace to begin with
Not every home in Riverdale has gas service. Swap the comparison to resistance heat instead of gas, and Riverdale's answer improves. About $1,539 a year comes back this way, enough that the 5.2-year payback clears the $8,000 premium comfortably within the equipment's life.
How Riverdale compares nationally
Ranked against the other 3206 cities covered, Riverdale comes in at 788 for heating severity — 1 would be the coldest place in the dataset — and 3127 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
Deciding what's next in Riverdale, IL
About 10,299 people live in Riverdale, Illinois, 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.

Every constant behind this page — the 2.57 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Riverdale's -5.3°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.
