The best time to make a Chicago home more efficient is while it is open for a remodel. With drywall off and floors up, your crew can air seal and insulate the walls, run new circuits for induction or a heat pump, and plan efficient lighting with far less disruption than later. Before you commit, check the current offers from ComEd and your gas utility, and plan without the 2 main federal home energy tax credits: the IRS says they do not cover work installed after 2025.
This guide covers which upgrades to plan, what Chicago’s permit list says about them, and which programs are worth checking as of November 2026. Terms change every year and no rebate is guaranteed, so confirm eligibility with each program before you build.
Why a Remodel Is the Best Time for Energy Work
Many of the most useful energy upgrades sit behind finished surfaces: gaps around pipes and wires, empty wall cavities, and the rim joists where the floor framing meets the foundation. In a finished home, reaching them means cutting and patching. In a remodel, the opening is already there.
The U.S. Department of Energy’s insulation and air sealing guidance notes that walls and rim joists typically make up more than 40% of a house’s envelope area. A remodeling guide from the editors of Home Energy magazine, published on the Department of Energy’s website, puts it simply: if you are tearing out wallboard for a kitchen or bath, use that open cavity to air seal and insulate the wall.
Start With a Free Energy Assessment
Peoples Gas says it partners with ComEd on a free energy assessment with personalized recommendations for upgrades that qualify for rebates. As of November 2026, owners of single-family homes, two-flats and individually metered condos and townhomes are eligible. Book it before your design is final, so the findings shape the plan.
Seal and Insulate While the Walls Are Open
ENERGY STAR says sealing air leaks and adding insulation can make a home more comfortable and save up to 10% on annual energy bills. The Department of Energy adds that in an existing home, air sealing some parts of the house may only be practical during a major renovation.
Air Seal First
Order matters: both Peoples Gas and Nicor Gas pay attic insulation rebates only when the project includes air sealing. The Department of Energy’s guidance points to places a remodel exposes:
- The attic floor: seal around recessed lights, HVAC registers and other openings into the living space.
- Rim joists: in an unfinished basement, caulk or spray foam can “picture frame” each joist bay.
- Windows and doors: seal between the frame and the house framing with foam backer rod and caulk, or low-expansion foam.
- Every new hole: seal around each pipe and wire run through the walls.
Insulate the Open Cavities
With the studs exposed, insulating an exterior wall is far simpler than in a finished room. If the project includes new siding, the Department of Energy calls that the best time to add continuous insulation outside the framing. Pipes count too: Peoples Gas offers rebates for insulating boiler and hot water piping.
Old Walls Need Care
The City of Chicago says work must follow asbestos and lead-safe work practices, and you may need to file a notice with the Chicago Department of Public Health first. Nicor Gas recommends consulting a trained, certified professional before insulating an attic that holds vermiculite or perlite.
Windows and Exterior Doors
ENERGY STAR sets its window criteria by climate zone, based on National Fenestration Rating Council ratings, so look for a unit certified for your zone.
The city’s list of work that needs no permit includes replacing an exterior window in-kind in its existing opening, in a residential building up to 4 stories. In-kind means the same type, size and shape, so a new or enlarged opening is a different project. The exceptions may not apply to a Chicago Landmark or a home in a landmark district. If you are keeping original windows, the same list exempts storm windows in any building, and Nicor Gas offers rebates on ENERGY STAR certified low-e storm window inserts.
In a high-rise condo, windows and heating and cooling are often tied to building systems, so start with your association. Our guide to condo board approval for a Chicago remodel covers that process.
Heat Pumps and Efficient Heating and Cooling
ENERGY STAR says an air-source heat pump can deliver up to 3 times more heat energy than the electricity it uses, and it cools in summer as well. For a Chicago winter, 3 points matter:
- Ask for a cold climate model. ENERGY STAR’s cold climate certification requires verified performance in tests down to 5°F. The units keep working below that, but ENERGY STAR says a backup heat source is most efficient in deeper cold.
- Consider dual fuel. With a fairly new furnace and an old air conditioner, ENERGY STAR suggests a heat pump, creating a dual-fuel system that heats with whichever source works best.
- Size it to the finished house. ENERGY STAR recommends a “Manual J” load calculation. Since insulation and air sealing change what the house needs, size the system after the envelope plan is set.
On permits, the city exempts in-kind replacement of a furnace, boiler or air conditioner in residential buildings up to 4 stories; otherwise, complete replacement requires a building permit. A heat pump in place of a furnace is a new type of equipment, so plan on a permit.
Induction Cooking and Electrical Capacity
ENERGY STAR says induction transfers about 85% of its heating energy to what is in the cookware, compared with about a third for gas, and heats faster. To check your pans, try a magnet: if it sticks, it works.
The planning question is electrical. ENERGY STAR’s electric-ready checklist notes that new 240-volt outlets may be needed for a stove, heat pump, heat pump water heater, dryer or EV charger, and recommends a licensed electrician review your panel. It adds that the cost of a new circuit depends partly on how easily the electrician can get into the walls, which a remodel provides. Even if you are not switching now, consider running circuits for later.
Swapping the cooktop itself is on the city’s no-permit list, but new circuits are not. For one luxury option, see our post on induction cooktops in luxury kitchens.
Lighting and Controls
The Department of Energy says LEDs use 75% less energy and last up to 25 to 50 times longer than incandescent bulbs. Open ceilings make it the moment to plan layered LED lighting and dimming, and to seal recessed fixtures below an attic. Our guide to lighting for Chicago kitchens goes further on layout.
Peoples Gas and Nicor Gas both list smart thermostat rebates for 2026. With a heat pump, ENERGY STAR advises picking a comfortable temperature and leaving it, because heat pumps do not save energy the way furnaces do when turned down.
The Rebates Worth Checking in November 2026
Utility offers are set by program year and paid only when you meet each program’s rules. Check them before you sign, and again before installation.
ComEd Energy Efficiency Program
ComEd says its Energy Efficiency Program’s Home Heating and Cooling offering provides discounts on heat pump installations through participating contractors, and reported in May 2026 that it had supported more than 20,000 customer installations. Its full list of home offers is at ComEd.com/WaystoSave.
Peoples Gas, North Shore Gas and Nicor Gas
Peoples Gas delivers natural gas in the city of Chicago. Its home energy rebates cover furnaces, boilers, water heaters, smart thermostats, gas heat pumps, pipe insulation, and insulation and air sealing, and its 2026 application also covers North Shore Gas customers. As of November 2026:
- Weatherization rebates are paid only for work by approved contractors, as instant discounts, up to $1,200 per project, and wall and attic insulation rebates require air sealing in the same project.
- Equipment must be installed during 2026, with the application in within 30 days of installation or by December 31, 2026, whichever comes first.
- The project must replace equipment in an existing building, and the existing equipment must be operational when you apply. If your remodel removes a system early, ask the program how that applies before demolition.
If your gas comes from Nicor Gas, its 2026 rebates require a program approved contractor for air sealing, insulation, duct sealing and windows, and an application within 90 days of installation or by January 31, 2027, whichever comes first. Its window rebates require any air sealing to be finished first.
These offers cover installations in 2026. A project that finishes in 2027 would fall under that year’s terms, if the programs continue.
Illinois Programs
As of November 2026, the Illinois EPA says the state’s federally funded Home Energy Rebate Programs are not yet launched: one pilot is pending federal approval, and it plans to direct the funds first to low-income households, with no retroactive rebates. Income-qualified households can look to the Illinois Home Weatherization Assistance Program, which can fund air sealing and insulation. Peoples Gas also points customers to the Illinois Energy Efficiency Loan Program, which lets you pay for improvements through a monthly charge on your utility bill.
What Changed With Federal Tax Credits
A federal law of July 4, 2025 brought forward the end of 2 key credits. The IRS fact sheet on the change says:
- The Energy Efficient Home Improvement Credit, which covered items such as insulation, windows and heat pumps, is not allowed for any property placed in service after December 31, 2025.
- The Residential Clean Energy Credit, which covered items such as solar panels and geothermal heat pumps, is not allowed for expenditures made after December 31, 2025. The IRS treats the expenditure as made when installation is complete, so paying early does not help if installation finished later.
Some websites, including older government pages, still describe these credits as running into the 2030s. Go by the IRS fact sheet linked above. For qualifying work installed in 2025, the home improvement credit is claimed for the year of installation on Form 5695. A tax professional can confirm how this applies to you.
How to Sequence Energy Upgrades in Your Remodel
Areté has worked as a design-build firm in Chicago since 2002, with design and construction under one roof and an in-house interior design team. Each project is run by a Project Manager. That matters for energy work because the decisions are linked: the envelope sets the equipment size, the equipment sets the electrical load, and the programs set who may do the work. A well-run plan for residential remodeling in Chicago follows a clear order.
- Assess. Book the free assessment and note the age of every system.
- Check the programs. Confirm contractor rules, product requirements and deadlines before the design is final.
- Seal, then insulate. Do the envelope while walls are open, and finish air sealing before new windows.
- Size the systems after the envelope plan is set.
- Plan the electrical for induction, a heat pump and future equipment.
- Sort out permits. Our guide to Chicago remodeling permits explains what needs one.
- Keep the paperwork. Save invoices, model numbers and before-and-after photos.
Whether it is one room of interior remodeling in Chicago or a whole house, the Chicago residential remodeling team at Areté can build these steps into your schedule.
Frequently Asked Questions
Can I Still Get a Federal Tax Credit for Insulation or a Heat Pump in 2026?
Not under the 2 main home credits, according to the IRS: they do not cover property placed in service, or expenditures made, after December 31, 2025. Check irs.gov and a tax professional for your situation.
Do I Have to Use an Approved Contractor for Utility Rebates?
For weatherization, usually yes. As of November 2026, Peoples Gas and Nicor Gas both require their approved contractors for air sealing, insulation and duct sealing rebates, and Nicor also for windows.
Is a Heat Pump Practical in a Chicago Winter?
It can be. ENERGY STAR certifies cold climate models tested down to 5°F and suggests backup heat for deeper cold. ComEd notes that many of its customers choose a dual-fuel system that pairs a heat pump with a gas furnace.
Do I Need a Permit for New Windows in Chicago?
Not always. The city exempts in-kind replacement in the existing opening in residential buildings up to 4 stories. A new opening, a taller building or a landmark property can change that, so confirm with the Department of Buildings or your contractor.
