Denver / Allenspark
Allenspark has 825 residents (give or take 268) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0801420, checked 2026-10-19), about 69 people per square mile.
Allenspark is about 47 miles from the Census center point for Denver in a straight line and covers 11.938 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).
Allenspark is spread out at 69 people per square mile across 11.938 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 412 occupied homes in Allenspark, 6% heat with natural gas, 0% with heating oil, 19% with electricity and 50% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0801420, checked 2026-10-19).
Propane leads in Allenspark at 50%, ahead of electricity at 19%, and a propane home is the clearest heat pump case on this door because delivered fuel is priced per gallon with no pipe to fall back on.
Allenspark has about the Boulder County oil share of 0% and 6 points less electric heat than the county's 25% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US08013, checked 2026-10-19).
Allenspark has 903 housing units, 26% built before 1940 and 79% before 1980, with 6% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0801420, checked 2026-10-19).
Allenspark has 20 points more pre-1940 homes than Boulder County as a whole (6%) and 20 points fewer homes built after 2000 than the county's 26% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US08013, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Allenspark home was built in 1948 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0801420, checked 2026-10-19) and the median home has 4.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0801420, checked 2026-10-19).
99% of Allenspark homes are single-family detached, 0% are in two- to four-unit buildings and 1% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0801420, checked 2026-10-19).
With 99% detached houses and 0% in small multi-family buildings, a Allenspark quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 18% of Allenspark homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0801420, checked 2026-10-19), the landlord signs the quote in many of them.
Allenspark has 42 points more detached houses than Boulder County overall (57%) and 25 points fewer five-plus-unit buildings than the county's 26% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US08013, checked 2026-10-19).
79% of Allenspark homes were built before 1980 and only 6% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0801420, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Allenspark 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 Allenspark address before counting it. With 19% of Allenspark homes already on electric heat and 56% 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 Allenspark is $108,056 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0801420, 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 -2F figure is the Boulder County cold-day number a Allenspark heat pump is sized against, so ask the installer to show the system's heating output at -2F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Allenspark home has 4.2 rooms and was built around 1948, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
