Green Bay Weather and HVAC Load
NOAA's 1991-2020 climate normals put Green Bay at 7,779 heating degree days and 425 cooling degree days per year. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. A normal year brings 159 nights at or below freezing and 6 days over 90°F. Snowfall averages about 56 inches. On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.

Green Bay Housing Stock
Half the homes in Green Bay were built before 1971 (Census ACS median), so the typical house is about 55 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Green Bay has roughly 25,000 owner-occupied homes, or 55.9% of households. Homes here have a median value of $191,500 and households a median income of $62,546. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 8 hail days and 21 days with damaging thunderstorm winds in Brown County. 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.
Symptoms Worth a Service Call
- The AC runs, but the air coming out is warm
- Ice on the refrigerant lines or the indoor coil
- The system cycles on and off every few minutes
- The outdoor unit hums, but the fan doesn't spin
- The breaker trips when the AC kicks on
What Moves the Price
- The service call or diagnostic fee
- Nights, weekends and holidays
- Whether the equipment sits in a tight attic or on a roof
- Refrigerant type and how many pounds it takes
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both

Wisconsin Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Wisconsin the company should carry a state license or registration. Ask for both.
Before You Hire
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
- Swap the air filter and check the breaker before you call anyone.
- Ask for the per-pound refrigerant price before any work starts.
