Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Madison cold snaps, call right away if freezing weather is forecast — a home without heat risks frozen pipes. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Pipes freezing while heat is out
If you will be away during cold weather, the American Red Cross advises leaving the heat on and set no lower than 55°F (Red Cross). If your Madison home’s heat has failed and freezing weather is forecast, call for service right away.
AC out during a summer heat wave
Outdoor unit silent · warm air at vents · short-cycling. An AC failure in Madison summer heat is worth a same-day call. Electrical and refrigerant faults need a technician to diagnose.

HVAC in Madison, WI: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Wisconsin licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Dane County Regional Airport (KMSN) is the official NOAA reference station for Madison. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00014837), Madison records an annual mean temperature of 47.0°F, an average annual maximum of 56.5°F against an annual minimum of 37.6°F, approximately 7,138.2 annual heating degree days against 627.4 cooling degree days, an annual precipitation normal of 37.13 inches, and an annual snowfall normal of 51.8 inches. The roughly 11:1 HDD-to-CDD ratio makes Madison a strongly heating-dominated market — equipment sizing, fuel choice, and cold-climate heat pump considerations all flow from this asymmetry.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 House Heating Fuel and B25035 Median Year Structure Built for Madison city, Wisconsin) report 125,787 occupied housing units with a median year built of 1979. Heating-fuel distribution: 67.8% utility natural gas (85,281 units), 28.4% electricity (35,768 units), 1,992 units on bottled/tank/LP gas, and 413 on fuel oil or kerosene. Natural gas furnaces dominate the installed base, so AFUE upgrades and gas-side rebates carry meaningful weight here. The 28% electric share also reflects substantial multifamily and electric-resistance stock that is candidate territory for cold-climate heat pump conversion.
Wisconsin DSPS
Per the Wisconsin Department of Safety and Professional Services (DSPS), “no person, entity or business may engage or offer to engage in installing or servicing heating, ventilating or air conditioning equipment unless the person, entity or business holds a registration issued by the Department.” Owner-occupants servicing HVAC equipment in their own residence are exempt. All initial applications, reinstatements, and renewals are submitted through Wisconsin’s online licensing portal at license.wi.gov. DSPS can be reached at (608) 266-2112 or (877) 617-1565.
Focus on Energy (WI)
Wisconsin’s statewide energy-efficiency utility, Focus on Energy, administers residential HVAC rebates that apply to Madison Gas and Electric (MGE) customers. Current air-source heat pump instant discounts are tiered by efficiency: Tier 1 (SEER2 15.2 / HSPF2 8.1) = $400 standard / $600 income-qualified, Tier 2 (SEER2 15.2 / HSPF2 8.5) = $500 / $700, Tier 3 (SEER2 16.0 / HSPF2 9.0) = $600 / $800, and Tier 4 (SEER2 16.0 / HSPF2 10.0) = $700 / $900 (lower amounts apply when replacing propane heat). Certified geothermal heat pump rebates are $1,000 for homes with natural gas service and $750 without. Per Focus on Energy, rebate applications (as opposed to instant discounts) must be submitted within 60 days of installation and no later than January 31, 2027.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
