Phoenix / Douglas
Douglas has 15,981 residents (give or take 41) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0420050, checked 2026-10-19), about 1,601 people per square mile.
Douglas is about 211 miles from the Census center point for Phoenix in a straight line and covers 9.981 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 4,566 occupied homes in Douglas, 63% heat with natural gas, 0% with heating oil, 34% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0420050, checked 2026-10-19).
Gas heats 63% of Douglas against electricity at 34%, 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.
Douglas has about the Cochise County oil share of 0% and 1 points less electric heat than the county's 35% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US04003, checked 2026-10-19).
Douglas has 5,468 housing units, 20% built before 1940 and 69% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0420050, checked 2026-10-19).
Douglas has 13 points more pre-1940 homes than Cochise County as a whole (7%) and 15 points fewer homes built after 2000 than the county's 28% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US04003, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Douglas home was built in 1969 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0420050, checked 2026-10-19) and the median home has 5.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0420050, checked 2026-10-19).
74% of Douglas homes are single-family detached, 6% are in two- to four-unit buildings and 9% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0420050, checked 2026-10-19).
With 74% detached houses and 6% in small multi-family buildings, a Douglas quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 37% of Douglas homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0420050, checked 2026-10-19), the landlord signs the quote in many of them.
Douglas has 9 points more detached houses than Cochise County overall (65%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US04003, checked 2026-10-19).
69% of Douglas homes were built before 1980 and only 13% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0420050, 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 Douglas on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
SRP Cool Cash variable-capacity heat pump rebate, run by SRP, is a live program for Arizona addresses and covers qualifying equipment at $1,000 per system (registry row 32 verified 2026-10-14, https://www.srpnet.com/energy-savings-rebates/home/rebates/air-conditioner, checked 2026-10-16); confirm eligibility for the Douglas address before counting it. With 34% of Douglas homes already on electric heat and 64% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Efficiency Arizona HEAR (Home Efficiency and Electrification Rebates): $8,000 usd_max (https://efficiencyarizona.com/, checked 2026-10-16); confirm eligibility for the address.
Median household income in Douglas is $42,019 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0420050, 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: 16F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Cochise County row, 99% heating, PDF pages 7 to 8 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 16F figure is the Cochise County cold-day number a Douglas heat pump is sized against, so ask the installer to show the system's heating output at 16F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 63% of Douglas on gas and 34% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Douglas home has 5.3 rooms and was built around 1969, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
