Madison Weather and HVAC Load
In a normal year, Madison racks up 7,096 heating and 639 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Madison put in far more hours than the air conditioner. On average, Madison gets 157 freezing nights and 10 days above 90°F per year. Snowfall averages about 39 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 70,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Madison Housing Stock
Half the homes in Madison were built before 1979 (Census ACS median), so the typical house is about 47 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. Madison has roughly 59,000 owner-occupied homes, or 46.6% of households. Homes here have a median value of $346,900 and households a median income of $76,983. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 24 hail days and 30 days with damaging thunderstorm winds in Dane 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. Dane County also had 7 tornado days in that period.
When It Makes Sense
- Energy bills are higher than you want them to be
- Your AC needs replacing, and you'd like cheaper heat at the same time
- There's no natural gas service on your street
What Moves the Price
- A ducted system or a ductless mini-split
- Size in tons, and whether the unit is cold-climate rated
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Electrical panel capacity and wiring
- Variable-speed (inverter) or single-stage compressor

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. Expect the contractor to pull a mechanical permit for a replacement job in Madison. If a bidder suggests skipping it, move on. Also ask for a Wisconsin 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
- Make sure the installer sized the system for your heating load, not only cooling.
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.
- Where winters get cold, ask for a model on the NEEP cold-climate list.

Heat Pump Installation Questions from Madison Homeowners
How much is heat pump installation in Madison?
Plan on $6,800 to $16,800, with most jobs near $12,300. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Madison?
Between late spring and early fall. Madison averages 157 freezing nights a year, and heating calls spike from November through February.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
