Skokie Weather and HVAC Load
NOAA's 1991-2020 climate normals put Skokie at 6,365 heating degree days and 805 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Skokie put in far more hours than the air conditioner. A normal year brings 128 nights at or below freezing and 17 days over 90°F. Snowfall averages about 34 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 6,365 |
|---|---|
| Cooling degree days / year | 805 |
| Nights at or below 32°F | 128 |
| Days above 90°F | 17 |
| Average low / high | 40.3°F / 59°F |
Skokie Housing Stock
Half the homes in Skokie were built before 1959 (Census ACS median), so the typical house is about 67 years old. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. About 18,000 households here own their home, 74.1% of the occupied total. With a median household income of $93,550 and a median home value of $368,600, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 27 hail days and 75 days with damaging thunderstorm winds in Cook County. The largest hail reported was 2.75 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. Cook County also had 8 tornado days in that period. In Skokie, 20.4% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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. Equipment replacements in Skokie generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Illinois license or registration number and a certificate of insurance with the quote. 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
