Kenosha Weather and HVAC Load
NOAA's 1991-2020 climate normals put Kenosha at 6,446 heating degree days and 721 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Kenosha put in far more hours than the air conditioner. Count on roughly 135 nights below 32°F and 11 afternoons past 90°F in a typical year. Snowfall averages about 36 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.

Wisconsin Permits, Efficiency Rules and Rebates
Wisconsin 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 Kenosha generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Wisconsin 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
- For a steam system, hire a contractor who works on steam regularly.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
