With a median household income of $90,109 and a median home value of $260,400, local labor rates come out above the national middle in our model.
NOAA storm reports for Kane County show 10 hail days and 48 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2.5 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Kane County also had 11 tornado days in that period.

Illinois Permits, Efficiency Rules and Rebates
Illinois falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Plan on a mechanical permit for most replacements in Aurora; the contractor normally pulls it. Before you sign, ask each bidder for their Illinois license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- Rinse the indoor filters once a month during heavy use.
