Madison / Lodi
Lodi has 3,204 residents (give or take 13) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5545350, checked 2026-10-19), about 1,856 people per square mile.
Lodi is about 17 miles from the Census center point for Madison in a straight line and covers 1.726 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Of the 1,415 occupied homes in Lodi, 93% heat with natural gas, 0% with heating oil, 6% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5545350, checked 2026-10-19).
Gas heats 93% of Lodi against electricity at 6%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Lodi has about the Columbia County oil share of 1% and 10 points less electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55021, checked 2026-10-19).
Lodi has 1,511 housing units, 23% built before 1940 and 44% before 1980, with 30% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5545350, checked 2026-10-19).
Lodi has 8 points more homes built after 2000 than the county's 22% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55021, checked 2026-10-19).
The median Lodi home was built in 1989 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5545350, checked 2026-10-19) and the median home has 6.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5545350, checked 2026-10-19).
68% of Lodi homes are single-family detached, 15% are in two- to four-unit buildings and 8% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5545350, checked 2026-10-19).
25% of Lodi homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5545350, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Lodi has 9 points fewer detached houses than Columbia County overall (77%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US55021, checked 2026-10-19).
No electric utility is on file for Lodi on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Focus on Energy air source heat pump instant discount (ratepayer), run by Focus on Energy, is a live program for Wisconsin addresses and covers qualifying equipment at $900 per system (registry row 20 verified 2026-10-07, https://assets.focusonenergy.com/production/docs/trade-ally/TAS-Trade-Ally-Solutions-Rebates-Overview-20260101_CLEAN.pdf, checked 2026-10-16); confirm eligibility for the Lodi address before counting it. With 6% of Lodi homes already on electric heat and 95% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Lodi is $117,584 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5545350, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: -3F.

That -3F figure is the Columbia County cold-day number a Lodi heat pump is sized against, so ask the installer to show the system's heating output at -3F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 93% of Lodi on gas and 6% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Lodi home has 6.4 rooms and was built around 1989, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
