Is Electrification Worth It in Illinois?
Chicago winters are cold. But they're not "heat pumps don't work" cold.
You'll see -10°F a few times each winter. That's exactly the temperature where older heat pumps started struggling and needed backup heat. But modern cold-climate units? They're fine. The bigger issue is Illinois electricity costs ($0.13/kWh ComEd, $0.11/kWh downstate) vs. natural gas ($1.05/therm). Gas is cheap here.
If you're in Chicago proper and heating with an old furnace, I'd probably stick with high-efficiency gas—unless you care a lot about emissions or indoor air quality. But if you're replacing both furnace AND AC, get a heat pump. The cooling efficiency gains pay for a chunk of it, and you get heating as a bonus. Downstate and collar counties have better economics.
What Do Energy Costs Look Like in Illinois?
Here's the real data from EIA (Energy Information Administration). These are the rates that determine whether electrification makes financial sense.
Visual ROI Analysis
Payback Period Comparison
Lower is better • Shortest payback = fastest return on investment
Annual Savings Comparison
Higher is better • More annual savings = greater long-term benefit
Cumulative Net Savings Over Time
Point where line crosses $0 = payback achieved • Steeper line = faster savings growth
Which Upgrades Pay Off the Fastest?
I've broken down the economics for each major upgrade. Pay attention to the payback period—that's how long until savings equal your net cost.
Heat Pump HVAC
Solar Panels
Heat Pump Water Heater
EV Charger + Electric Vehicle
Should You Go All-In?
Here's what it costs to electrify everything at once—heat pump HVAC, solar panels, heat pump water heater, and EV charger. The upfront cost is high, but so are the savings.
