Is a heat pump worth it in Pontiac?
In Pontiac, 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. The heat pump would cost about $156 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Pontiac's numbers say wait.
Why Pontiac's climate drives this number
4572 heating degree days pile up here every year, so Pontiac has a real but manageable winter; the cooling side runs to 942 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 6.8°F here (record low -4.2°F), which works out to a seasonal COP of 2.86 for the cold-climate class of unit this climate calls for. Pontiac 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. Climate figures trace to the nearest NOAA station, PONTIAC MUNICIPAL AIRPORT, 2.6 miles from Pontiac.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,048 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $925 a year. The gas furnace it replaces burns roughly 48 Mcf a year at 11.25 per Mcf here, for a running cost near $768 a year (electricity here runs 19.06¢/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 $5,844 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Pontiac — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Pontiac's answer improves. The saving here runs about $1,515 a year, which recovers the extra $8,000 spent going electric in roughly 5.3 years.
How Pontiac compares nationally
Ranked against the other 3206 cities covered, Pontiac comes in at 1116 for heating severity — 1 would be the coldest place in the dataset — and 2979 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
Next step for 11,054 people in Pontiac
About 11,054 people live in Pontiac, 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.
More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Pontiac's 2.86 seasonal COP and payback figure. Pontiac's 6.8°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.
