Colby is about 232 miles from the Census center point for Wichita in a straight line and covers 3.676 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 2,131 occupied homes in Colby, 85% heat with natural gas, 0% with heating oil, 14% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2014650, checked 2026-10-19).
Gas heats 85% of Colby against electricity at 14%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas boiler stays for the deepest cold, or a whole-home system when the house is ready for it.
Colby has about the Thomas County oil share of 0% and the same 14% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US20193, checked 2026-10-19).
Colby has 2,464 housing units, 15% built before 1940 and 79% before 1980, with 4% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2014650, checked 2026-10-19).
The median Colby home was built in 1969 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2014650, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2014650, checked 2026-10-19).
74% of Colby homes are single-family detached, 10% 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=160XX00US2014650, checked 2026-10-19).
With 74% detached houses and 10% in small multi-family buildings, a Colby quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 33% of Colby homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2014650, checked 2026-10-19), the landlord signs the quote in many of them.
No electric utility is on file for Colby on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 4F.

That 4F figure is the Thomas County cold-day number a Colby heat pump is sized against, so ask the installer to show the system's heating output at 4F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 85% of Colby on gas and 14% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Colby home has 5.6 rooms and was built around 1969, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
