Heat pump vs. furnace in Illinois by electric utility

What to know about the Illinois numbers

• Rebates not checked yet. We haven't checked heat pump rebates in Illinois yet, so the numbers here leave them out. Utility and state programs can take thousands off a heat pump, so ask your utility and your contractor what's available.
• Mostly average prices. Only 0% of Illinois ZIP codes here are priced on a current utility tariff. The rest use the utility's average price from the U.S. Energy Information Administration, which is about two years old and doesn't show tiers, so the winter price of extra kWh is estimated. Enter the rate from a recent bill for a closer answer.
• Supplier choice. Many Illinois households buy their electricity supply from a competitive supplier. We use the utility's standard price; if you buy from a supplier, enter your total price per kWh from your bill.
• Regional fuel prices. EIA doesn't publish a Illinois price for every fuel: heating oil uses the regional average. Enter your own price if you heat with it.
