Do I Need a Permit for HVAC in Aurora, IL?
Aurora's Climate Zone 5A — the cold/humid Chicago climate — creates some of the highest heating demand of any city in this guide. Natural gas heating (Nicor Gas) is the dominant choice for Aurora homeowners, and the gas furnace has been the workhorse of Chicago-area residential heating for generations. Heat pumps work well in Aurora's climate with modern equipment, but there's no Illinois code mandate driving the choice — homeowners decide based on their priorities.
Aurora HVAC permit rules — the basics
Aurora's Building & Permits Division processes mechanical permits through eTRAKiT. Standard same-location equipment replacements apply for the mechanical permit, and a separate electrical permit when circuit work is included. The 2026 fee schedule (annually indexed) governs permit costs — call (630) 256-3130 for current amounts. After the permit is issued, one final inspection is typically required after equipment installation, verifying the installation quality, refrigerant documentation, and gas connection integrity (for gas equipment).
Illinois licenses HVAC contractors under the Illinois Plumbing License Act (for gas piping work — which covers most heating equipment connections) and other state licensing requirements. Verify any HVAC contractor's Illinois license before hiring. Contractors must be registered with Aurora's Building & Permits Division before pulling permits. For gas furnace work specifically, the contractor must hold appropriate Illinois licensing for gas piping work — the city permit and inspection verify this through the contractor registration process.
ComEd (Commonwealth Edison / Exelon) serves Aurora for electricity. ComEd does not require pre-approval before Aurora mechanical permits can be applied for. For heat pump installations that require electrical panel upgrades — particularly conversions from gas-only heating to heat pump systems where the panel may not have adequate capacity — ComEd service upgrade coordination is required separately from the city permit. ComEd's service upgrade process in the Aurora/Chicago suburbs typically takes 2–4 weeks. Contact ComEd at 1-800-334-7661 for service upgrade coordination when applicable.
Nicor Gas serves most of Aurora for natural gas. For gas furnace replacements or modifications to gas lines serving HVAC equipment, a gas/plumbing permit and pressure test are required through the city's eTRAKiT system. Nicor Gas does not require pre-approval before the city permit is applied for for standard same-location equipment replacements. For new gas service connections or gas meter installations, Nicor Gas coordination is required — contact Nicor at 1-888-642-6748.
Three HVAC scenarios in Aurora, IL
| Variable | How it affects your Aurora HVAC permit |
|---|---|
| No Illinois heat pump mandate | Illinois has no equivalent to California's 2025 CMC heat pump prescriptive default. Aurora homeowners freely choose gas furnace, heat pump, or conventional AC based on their priorities — energy costs, installation cost, equipment reliability, and personal preference. The Chicago-area's gas heating tradition is well-established — Nicor Gas has extensive residential coverage and gas furnaces remain the dominant choice in Aurora's housing stock. |
| Climate Zone 5A — heat pump performance context | Aurora's cold winters (design heating temperature approximately -5°F to -10°F at the 99% design condition) pushed older-generation heat pumps toward their efficiency cliff. Modern cold-climate heat pumps rated to -13°F or -22°F perform well in Aurora's conditions, maintaining heating capacity and efficiency in all but the coldest extreme events. The federal Section 25C ITC (30%, up to $2,000 for qualifying cold-climate heat pump systems) provides meaningful incentive. ComEd's electricity rates in the Chicago area should be compared against Nicor Gas rates in the homeowner's specific annual energy cost calculation. |
| ComEd service upgrades for heat pump conversion | Heat pump installations in homes with 100A service — common in Aurora's pre-1980 housing stock — often require electrical panel upgrades to 200A. ComEd service upgrade coordination is required separately from the city permit — contact ComEd at 1-800-334-7661. ComEd's service upgrade process in the Aurora/Chicago suburbs typically takes 2–4 weeks. Apply for city permits and initiate ComEd coordination simultaneously to minimize project timeline. |
| Nicor Gas for gas furnace work | Nicor Gas serves most of Aurora. Gas furnace replacements in the same location with the same gas connection don't require Nicor Gas pre-approval — the city gas/plumbing permit and pressure test cover the installation. For new gas service connections (adding gas to a home converting from oil heat, or extending gas service), Nicor Gas coordination is required at 1-888-642-6748. Nicor Gas does not require pre-approval before the city permit is applied for for standard same-location gas equipment replacements. |
| A2L refrigerants | New HVAC equipment uses A2L refrigerants (R-32, R-454B) per EPA AIM Act phase-down. A2L refrigerants are mildly flammable and require enhanced installation safety protocols. Contractors must hold EPA Section 608 certification for A2L handling. The city mechanical permit documents the refrigerant type. This applies in Aurora as in all other cities in this guide — a national EPA requirement, not unique to Illinois. |
| HCOA for historic district properties | HVAC work on historic district properties may require HCOA review if any exterior element is changed — condenser placement, line set routing visible from the street, new penetrations through the building envelope. Rear-yard condenser placements that are not visible from the street typically don't require HCOA review. Contact the Historic Preservation Division at 630-844-3648 before planning equipment placement if the property is in a historic district. |
Heat pumps in Aurora's Chicago climate — the honest assessment
The question Aurora homeowners ask most when considering heat pumps is whether they work in Chicago winters. The answer for modern cold-climate equipment is yes — but with important context. Modern variable-speed cold-climate heat pumps (Mitsubishi, Daikin, Bosch, and similar) maintain rated heating capacity at temperatures as low as -13°F or lower. Aurora's average low in January is approximately 16°F; the 99% design condition (the coldest 1% of hours) is approximately -5°F to -10°F. Modern cold-climate heat pumps handle this well, though their heating COP (efficiency) decreases at the coldest temperatures — supplemental resistance heat kicks in during extreme cold events.
The practical financial analysis for an Aurora homeowner considering a heat pump vs. gas furnace involves comparing ComEd's electricity rates against Nicor Gas's gas rates. In the Chicago suburbs, electricity is more expensive per BTU of delivered heat than gas at most outdoor temperatures — but modern heat pumps deliver 2–4 BTU of heat for every 1 BTU of electricity consumed, making them competitive against gas even at Chicago-area utility rates. At high efficiency (Coefficient of Performance 2.5+), a heat pump competes well against gas heating on operating costs for most of the heating season in Aurora.
What HVAC costs in Aurora, IL
Aurora HVAC costs track the Chicago suburban market. Gas furnace + central AC replacement (same location): $6,500–$12,000. Cold-climate heat pump replacement (without panel upgrade): $9,000–$16,000. Cold-climate heat pump with panel upgrade: $12,000–$20,000. Ductless mini-split (multi-zone, 3 zones): $9,000–$16,000. Permit fees per the 2026 annually indexed schedule are modest — typically $100–$250 for standard equipment replacements. Federal Section 25C ITC (30%, up to $2,000 for qualifying heat pump systems) reduces net cost for qualifying installations.
