What Naperville Electric pays in 2026
Naperville gives the rebate as a one-time credit on your utility bill, usually within two months of approval. Each application goes through the city's online portal.
Air source heat pump
$900 for 15.2 SEER2 or better, $1,400 for 17 SEER2 or better if you keep a gas furnace for backup, $1,800 for 17 SEER2 or better with no gas backup. Heating rating must be 8.1 HSPF2 or better.
Smart thermostat
For any Wi-Fi smart thermostat. Limit of two per household. Owners and renters can apply.
Attic insulation, windows, tune-ups
Attic insulation, single-pane window replacement, furnace blower motor and air conditioner tune-up rebates are used up for the year.
Because Naperville has its own electric utility, you cannot also claim ComEd's heat pump discount at the same address. For gas rebates, Naperville homes use Nicor Gas.
Why Naperville is different
Most of the Chicago suburbs buy their electric delivery from ComEd. Naperville is an exception: its customers pay the City of Naperville Department of Public Utilities for electric service, and the city sets its own rebate programs. If your electric bill comes from the city, use this page. If it comes from ComEd, use our ComEd guide instead.
Gas is separate. Nicor Gas serves Naperville, and its list of served communities includes it. Nicor's rebates are for gas equipment that replaces gas equipment. See our Nicor Gas guide.
How the heat pump amounts work
The city pays more when you pick a more efficient unit and more again when you give up gas backup. A heat pump that meets 15.2 SEER2 gets $900. A heat pump that meets 17 SEER2 gets $1,400 if you keep your gas furnace as a backup, and $1,800 if you remove it. The unit must be a replacement, must be sized for a home (65,000 Btu per hour or smaller) and must show its ratings on an AHRI certificate, which is the industry's rating sheet.
There is a limit of one incentive per household, and the city must receive your complete application within 120 days of the install date. The program ends when its funding is all allocated, and the page does not say how much is left, so apply soon after the work.
The renewable energy rule on the closed programs
For attic insulation, windows, solar, the tune-up and the blower motor, Naperville asks you to give at least $5 a month to its Renewable Energy Program for five years. Those contributions pay for the rebates. The city says it gave out 100 percent of the $280,000 budget as of June 26, 2026, and that applications are closed for the rest of the calendar year. The attic rebate was $1 a square foot up to $2,500, and windows were $250 each up to $2,500. The page does not say when they reopen, so check in January.
The heat pump and thermostat pages did not list that rule or that closure, but we could not tell whether those two have enough money left. Ask the city at 630-305-5357 before you buy.
Naperville's housing in numbers
The Census Bureau's survey for 2020 to 2024 counts 57,135 homes in Naperville. About 75% of occupied homes are owned and 25% are rented. Detached houses are 62.8% of the stock, and only 25.8% of homes were built before 1980, the lowest share of our four Illinois cities. Utility gas heats 86.1% of homes and electricity 11.9%. With so many newer, gas-heated homes, the heat pump rebate with gas backup at $1,400 may fit more households than the $1,800 full switch.
Free help and state programs
The state's weatherization program covers income-eligible Naperville households with free work, whatever their electric company. See the Illinois hub for the income limits.

Common questions
Does ComEd serve Naperville?
No. Naperville's electric service comes from the City of Naperville's own electric utility, which has separate rebates.
How much does Naperville pay for a heat pump?
$900, $1,400 or $1,800 depending on efficiency and whether you keep a gas furnace for backup.
Can renters apply?
For the heat pump and smart thermostat, owners and renters who are residential electric customers can apply.
Why are attic and window rebates closed?
The city says it gave out the full $280,000 budget as of June 26, 2026 and closes applications for the rest of the year once that happens.
How long do I have to apply?
The city must receive your complete application within 120 days of installation.
Is there a state solar rebate I can use instead?
Illinois Shines pays for the credits your solar panels create, but we did not read whether Naperville's utility customers get the same pricing. Ask the city and an approved vendor.
