Denver / Denver
Denver has 718,877 residents (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0820000, checked 2026-10-19), about 4,696 people per square mile.
Denver is the city this door is named for; it covers 153.074 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).
The quote form takes a ZIP code; for Denver that is 80202, 80203, 80204, 80205, 80206, 80207, 80209, 80210 and 24 more (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Median household income in Denver is $94,718 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0820000, 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.
4,696 people per square mile puts Denver in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
40% of Denver homes are single-family detached, 5% are in two- to four-unit buildings and 45% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0820000, checked 2026-10-19).
With 45% of Denver homes in buildings of five or more units and 40% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 51% of Denver homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0820000, checked 2026-10-19), the landlord signs the quote in many of them.
51% of Denver homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0820000, 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.
Of the 335,428 occupied homes in Denver, 61% heat with natural gas, 0% with heating oil, 36% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0820000, checked 2026-10-19).
Gas heats 61% of Denver against electricity at 36%, 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.
Denver has about the Denver County oil share of 0% and the same 36% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US08031, checked 2026-10-19).
No electric utility is on file for Denver 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 Denver address before counting it. With 36% of Denver homes already on electric heat and 62% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Denver has 359,581 housing units, 17% built before 1940 and 55% before 1980, with 31% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0820000, checked 2026-10-19).
Denver tracks Denver County on housing age, with the county at 17% pre-1940 and 31% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US08031, checked 2026-10-19).
The median Denver home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0820000, checked 2026-10-19) and the median home has 4.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0820000, checked 2026-10-19).
Heating design temperature: -2F.

That -2F figure is the Denver County cold-day number a Denver 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 whether the quote is whole-home or partial-home, because with 61% of Denver on gas and 36% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Denver home has 4.5 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
