Home Service Costs in Naperville, IL
The questions Naperville homeowners ask before every big repair — what does a water heater cost, a roof, a furnace, a panel upgrade? — answered trade by trade. Every figure is labeled with where it comes from (Angi's 2026 national or Chicago-area data — no Naperville company publishes a price list), and the permit fees are the City of Naperville's own published numbers.

How to read these numbers
Three honesty rules for this page. One: with almost no exceptions, Naperville-area companies do not publish prices — you get numbers by estimate or quote, so the dollar figures here are Angi's 2026 cost data, national unless the figure says "Chicago area." They're the yardstick for judging a quote, not a quote. Two: the one company policy worth knowing for each trade is called out where a company publishes it (free estimates, flat-rate quotes). Three: permit fees are different — those are published by the City of Naperville itself, and they're below in black and white.
Plumbing costs
| Job | Typical range | Source |
|---|---|---|
| Water heater replacement — tank | $882–$1,826 | Angi 2026, national (avg ≈ $1,348) |
| Water heater — tankless install | $1,406–$3,902 | Angi 2026, national (avg ≈ $2,641) |
| Drain cleaning | $165–$414 | Angi 2026, Chicago area (avg ≈ $288) |
| Main sewer line clearing | $250–$900 | Angi 2026, Chicago area |
| Sump pump replacement | $309–$755 | Angi 2026, national (avg ≈ $531) |
| Plumber labor | $45–$200/hr | Angi, Chicago area |
Naperville permit angle: the City's Guide to Building Permits requires a permit for new water heaters (including a change of fuel or power source) but states that no permit is required to replace an in-kind unit — same type, same fuel, same spot. Piping changes are permit work; clearing stoppages and repairing leaks are not. Illinois plumbers are licensed by the Illinois Department of Public Health (IDPH) — our Naperville plumbers guide walks through the two-minute license check and lists the local companies.
Roofing costs
| Job | Typical range | Source |
|---|---|---|
| Full roof replacement | ≈ $9,610 average | Angi 2026, national — roughly $4–$11 per sq ft by material and pitch |
| Replacement, 1,340 sq ft roof | $5,800–$14,700 | Angi 2026, national |
| Replacement, 1,800 sq ft roof | $8,800–$22,100 | Angi 2026, national |
| Roof repair | $395–$1,967 | Angi 2026, national (avg ≈ $1,174) |
| Tear-off of old roof | $1.20–$4.00 / sq ft | Angi 2026, national |
Naperville permit angle — a genuine money-saver: re-roofing a single-family home with asphalt composite shingles needs no City building permit as long as the existing roof sheathing stays in place. A permit is required for metal, wood, slate, or sealed-membrane roofing and whenever sheathing is replaced. But the City is clear that even permit-free work must meet code, and any roofer you hire must be licensed by the State of Illinois. Roofers are licensed under the Illinois Roofing Industry Licensing Act (225 ILCS 335) through IDFPR — verify a license number free in IDFPR's online License Lookup, and note the two license types: limited covers residential buildings of 8 units or fewer; unlimited covers residential, commercial, and industrial.

Heating & cooling costs
| Job | Typical range | Source |
|---|---|---|
| Furnace replacement | $2,823–$6,896 | Angi 2026, national (avg ≈ $4,814) |
| Central AC replacement | $3,887–$8,073 | Angi 2026, national (avg ≈ $5,978) |
| Furnace + AC together | $5,000–$12,500 | Angi 2026, national (avg ≈ $7,500) — usually cheaper than separate projects |
| New ductwork (if needed) | $3,000–$7,500 | Angi 2026, national — an adder on AC replacement, not part of the base price |
| Annual tune-up | $75–$200 | Angi 2026, national; service contracts run $150–$500/yr |
Naperville permit angle: same rule as plumbing — the City requires a permit for a new furnace or AC installation, but no permit for an in-kind replacement. When a permit is needed, the City's published fee schedule totals the air conditioner special permit at $88, inspection included. Local companies: our Naperville HVAC guide.
Electrical costs
| Job | Typical range | Source |
|---|---|---|
| Panel upgrade to 200 amps | $1,300–$2,000 | Angi 2026, national (avg ≈ $1,600; full range $800–$4,000+ with service/meter work) |
| Home EV charger installation | $554–$1,380 | Angi 2026, national (avg ≈ $967) — charger and any panel upgrade extra |
Naperville permit angle: electrical work in Naperville needs a City permit (minor repairs and low-voltage work under 25 volts are the standing exemptions), and the City's permit guide lists electricians among the trades that require a license. Two Naperville specifics matter here. First, the electric utility is the City itself — Naperville has owned its electric utility since 1899 — so anything touching the meter or the service drop is coordinated with the City of Naperville Electric Utility, not ComEd. Second, if the electrical project is an EV charger, the deeper Illinois guide — charger costs, panel math, and which rebates actually apply when your utility is municipal — is on our sister site: Chicago EV Charger installation cost guide. Local companies: our Naperville electricians guide.
What the City of Naperville itself charges
Most residential permits are priced from the City's published residential fee schedule. Simple "miscellaneous" permits are built from an $18 clerical fee + $25 per plan page + $50 per inspection (a reinspection is $68). Common projects are flat "special permits" that bundle the pieces — a few totals from the schedule:
- Air conditioner: $88 total
- Sewer repair: $88 total
- Water softener: $88 total
- Backflow preventer: $88 and up
- Fence: $88 total · Deck: $132 total · Solar: $132 total
The City calls the schedule a good-faith estimate — the TED Business Group (400 S. Eagle St., (630) 420-6100) sets the actual fee by project scope when you apply through the City's online Permitting, Plans and Licensing Portal. And remember the flipside from the sections above: in Naperville, the most common like-for-like replacements — water heater, furnace, AC — need no permit and no fee at all.
Cost FAQ
How much does it cost to replace a water heater in Naperville?
Per Angi's 2026 national data, a standard tank water heater replacement runs $882–$1,826 installed (average about $1,348), and a tankless installation runs $1,406–$3,902 (average about $2,641). One Naperville break on the price: swapping an in-kind unit — same type, same fuel, same spot — needs no City permit at all under the City's Guide to Building Permits.
How much does a new roof cost in Naperville?
Per Angi's 2026 national data, roof replacement averages about $9,610 — roughly $4–$11 per square foot depending on material and pitch. By house size on the same data: a 1,340 sq ft roof runs $5,800–$14,700 and a 1,800 sq ft roof $8,800–$22,100. A tear-off of the old roof adds $1.20–$4.00 per square foot.
Does re-roofing need a permit in Naperville?
Usually not. The City of Naperville does not require a building permit to re-roof a single-family home with asphalt composite shingles as long as the existing roof sheathing stays in place. A permit is required for metal, wood, slate or sealed-membrane roofing, and whenever roof sheathing is replaced. Either way, any roofer you hire must hold an Illinois state roofing license.
How much does a furnace replacement cost?
Per Angi's 2026 national data, furnace replacement runs $2,823–$6,896, averaging about $4,814. Replacing the furnace and central AC together in one project runs $5,000–$12,500 (average about $7,500) — usually less than doing the two jobs separately in different years.
How much does a new AC cost — and does Naperville charge for the permit?
Per Angi's 2026 national data, central AC replacement runs $3,887–$8,073 (average about $5,978), and new ductwork, if your home needs it, adds $3,000–$7,500. On the city side: a like-for-like AC replacement needs no permit in Naperville, while a new installation does — the City's published fee schedule totals the air conditioner special permit at $88, including the inspection.
How much does a 200-amp panel upgrade cost?
Per Angi's 2026 national data, upgrading to a 200-amp panel runs about $1,300–$2,000 for the panel and installation; Angi puts the average 200-amp upgrade at $1,600, with a wide range ($800 to over $4,000) when service lines or meter work are involved. In Naperville the work needs a City electrical permit, and because the City owns the electric utility, service-side changes are coordinated through the City as well.
How much does it cost to install a home EV charger in Naperville?
Per Angi's 2026 national data, home EV charger installation runs $554–$1,380, averaging about $967 — before the charger itself and before any panel upgrade, which Angi lists at $800–$2,000 when the existing panel can't carry the load. Naperville is ComEd-independent: the City runs its own electric utility, so utility-side questions go to the City of Naperville Electric Utility, not ComEd.
How do I check a roofer's license in Illinois?
Illinois roofers are licensed by the state under the Illinois Roofing Industry Licensing Act (225 ILCS 335), administered by the Illinois Department of Financial and Professional Regulation (IDFPR). Ask for the company's roofing license number, then search it free in IDFPR's online License Lookup. Check that the license is the right type — a limited license covers residential work on buildings of 8 units or fewer, an unlimited license covers residential, commercial and industrial — and that it is active.
