Phoenix / Coolidge
Coolidge has 16,636 residents (give or take 39) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0415500, checked 2026-10-19), about 199 people per square mile.
Coolidge is about 55 miles from the Census center point for Phoenix in a straight line and covers 83.473 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 Coolidge that is 85128 (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).
Coolidge is spread out at 199 people per square mile across 83.473 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 5,359 occupied homes in Coolidge, 21% heat with natural gas, 0% with heating oil, 73% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0415500, checked 2026-10-19).
Electricity already heats 73% of Coolidge homes, ahead of gas at 21%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Coolidge has about the Pinal County oil share of 0% and 12 points more electric heat than the county's 61% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US04021, checked 2026-10-19).
Coolidge has 5,876 housing units, 3% built before 1940 and 36% before 1980, with 52% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0415500, checked 2026-10-19).
Coolidge has 13 points fewer homes built after 2000 than the county's 65% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US04021, checked 2026-10-19).
The median Coolidge home was built in 2001 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0415500, 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=160XX00US0415500, checked 2026-10-19).
85% of Coolidge homes are single-family detached, 1% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0415500, checked 2026-10-19).
With 85% detached houses and 1% in small multi-family buildings, a Coolidge quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 27% of Coolidge homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0415500, checked 2026-10-19), the landlord signs the quote in many of them.
Coolidge has 8 points more detached houses than Pinal County overall (77%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US04021, checked 2026-10-19).
52% of Coolidge housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0415500, 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 Coolidge 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 Coolidge address before counting it. With 73% of Coolidge homes already on electric heat and 23% 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 Coolidge is $67,023 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0415500, 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: 25F.

That 25F figure is the Pinal County cold-day number a Coolidge heat pump is sized against, so ask the installer to show the system's heating output at 25F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Coolidge home has 5.6 rooms and was built around 2001, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
