The quote form takes a ZIP code; for Parker that is 80134 (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).
Of the 21,789 occupied homes in Parker, 75% heat with natural gas, 0% with heating oil, 24% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0857630, checked 2026-10-19).
Gas heats 75% of Parker against electricity at 24%, 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.
Parker has about the Douglas County oil share of 0% and 1 points more electric heat than the county's 23% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US08035, checked 2026-10-19).
Parker has 22,397 housing units, 0% built before 1940 and 3% before 1980, with 63% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0857630, checked 2026-10-19).
Parker has 7 points more homes built after 2000 than the county's 56% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US08035, checked 2026-10-19).
The median Parker home was built in 2004 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0857630, checked 2026-10-19) and the median home has 6.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0857630, checked 2026-10-19).
70% of Parker homes are single-family detached, 1% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0857630, checked 2026-10-19).
With 70% detached houses and 1% in small multi-family buildings, a Parker quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 28% of Parker homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0857630, checked 2026-10-19), the landlord signs the quote in many of them.
63% of Parker housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0857630, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for Parker 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 Parker address before counting it. With 24% of Parker homes already on electric heat and 75% 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 Parker is $133,369 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0857630, 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 Douglas County cold-day number a Parker 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 75% of Parker on gas and 24% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Parker home has 6.6 rooms and was built around 2004, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
