Berwyn logs 5,752 heating degree days and 1,111 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in Berwyn put in far more hours than the air conditioner. A normal year brings 106 nights at or below freezing and 20 days over 90°F. Snowfall averages about 39 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. Berwyn has roughly 12,000 owner-occupied homes, or 61.1% of households.

Cook County had 27 hail days and 75 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.

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. Expect the contractor to pull a mechanical permit for a replacement job in Berwyn. If a bidder suggests skipping it, move on. Also ask for a 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
- A combi boiler frees up space and replaces your water heater.
- Ask your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
