The quote form takes a ZIP code; for Maricopa that is 85138 (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 21,038 occupied homes in Maricopa, 50% heat with natural gas, 0% with heating oil, 47% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0444410, checked 2026-10-19).
Gas heats 50% of Maricopa against electricity at 47%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Maricopa has about the Pinal County oil share of 0% and 14 points less 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).
Maricopa has 23,233 housing units, 0% built before 1940 and 2% before 1980, with 93% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0444410, checked 2026-10-19).
Maricopa has 28 points more 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 Maricopa home was built in 2007 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0444410, checked 2026-10-19) and the median home has 6.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0444410, checked 2026-10-19).
96% of Maricopa homes are single-family detached, 0% are in two- to four-unit buildings and 1% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0444410, checked 2026-10-19).
With 96% detached houses and 0% in small multi-family buildings, a Maricopa quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 16% of Maricopa homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0444410, checked 2026-10-19), the landlord signs the quote in many of them.
Maricopa has 19 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).
93% of Maricopa housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0444410, 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 Maricopa 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 Maricopa address before counting it. With 47% of Maricopa homes already on electric heat and 52% 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 Maricopa is $96,391 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0444410, 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 Maricopa 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 whether the quote is whole-home or partial-home, because with 50% of Maricopa on gas and 47% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Maricopa home has 6.5 rooms and was built around 2007, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
