Of the 71,768 occupied homes in Fort Collins, 66% heat with natural gas, 0% with heating oil, 31% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0827425, checked 2026-10-19).
Gas heats 66% of Fort Collins against electricity at 31%, 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.
Fort Collins has about the Larimer County oil share of 0% and 6 points more electric heat than the county's 25% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US08069, checked 2026-10-19).
Fort Collins has 74,558 housing units, 5% built before 1940 and 31% before 1980, with 37% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0827425, checked 2026-10-19).
Fort Collins tracks Larimer County on housing age, with the county at 5% pre-1940 and 39% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US08069, checked 2026-10-19).
The median Fort Collins home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0827425, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0827425, checked 2026-10-19).
52% of Fort Collins homes are single-family detached, 9% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0827425, checked 2026-10-19).
48% of Fort Collins homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0827425, checked 2026-10-19), so beside the 52% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Fort Collins has 12 points fewer detached houses than Larimer County overall (64%) and 10 points more five-plus-unit buildings than the county's 19% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US08069, checked 2026-10-19).
48% of Fort Collins homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0827425, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
No electric utility is on file for Fort Collins on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Colorado Heat Pump Tax Credit (HPTC), run by Colorado Energy Office, is a live program for Colorado addresses and lists a standard figure of $1,000 (registry row 4 verified 2026-10-15, https://energyoffice.colorado.gov/hptc, checked 2026-10-16); confirm eligibility for the Fort Collins address before counting it. With 31% of Fort Collins homes already on electric heat and 67% 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 Fort Collins is $85,070 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0827425, 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.

That 1F figure is the Larimer County cold-day number a Fort Collins heat pump is sized against, so ask the installer to show the system's heating output at 1F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 66% of Fort Collins on gas and 31% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Fort Collins home has 5.7 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
