On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

Aurora Housing Stock

Half the homes in Aurora were built before 1986 (Census ACS median), so the typical house is about 40 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Aurora has roughly 40,000 owner-occupied homes, or 66.8% of households. 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.

Symptoms Worth a Service Call

  • The outdoor unit hums, but the fan doesn't spin
  • The AC runs, but the air coming out is warm
  • Ice on the refrigerant lines or the indoor coil
  • Water pooling around the indoor unit
  • The system cycles on and off every few minutes

What Moves the Price

  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Whether the equipment sits in a tight attic or on a roof
  • Nights, weekends and holidays
  • Refrigerant type and how many pounds it takes
  • The service call or diagnostic fee

Illinois Licensing and Efficiency Rules

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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Illinois the company should carry a state license or registration. Ask for both.

Before You Hire

  • If you see ice, shut the system off. Running it frozen can kill the compressor.
  • Swap the air filter and check the breaker before you call anyone.
  • Ask for the per-pound refrigerant price before any work starts.
