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.
| Heating degree days / year | 6,446 |
|---|---|
| Cooling degree days / year | 721 |
| Nights at or below 32°F | 135 |
| Days above 90°F | 11 |
| Average low / high | 39.7°F / 58.7°F |
Kenosha Housing Stock
Census figures put the median build year in Kenosha at 1968, so a typical house here has about 58 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 23,000 households here own their home, 59.3% of the occupied total. With a median household income of $68,532 and a median home value of $210,500, local labor rates come out near the national middle in our model.
NOAA storm reports for Kenosha County show 3 hail days and 13 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Kenosha County also had 2 tornado days in that period.
When Replacement Makes Sense
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- The furnace is 15 to 20 years old or more
- Gas or electric bills keep climbing even though usage hasn't changed
- A repair quote runs past a third of the cost of a new unit
What Moves the Price
- New PVC venting if you move to a condensing model
- Condition of the existing ductwork and any changes it needs
- Permit and inspection fees, which the local building department sets
- Single-stage, two-stage or modulating gas valve
- BTU size, which should come from a Manual J load calculation
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
We raised the national figures about 9% for Kenosha using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Gas line and vent connections
- The permit and the manufacturer warranty registration
- Combustion and safety tests
- Removing and hauling away the old furnace
- The new furnace, filter rack and thermostat wiring
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
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
