Phoenix / Marana
Marana has 56,938 residents (give or take 81) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0444270, checked 2026-10-19), about 468 people per square mile.
Marana is about 94 miles from the Census center point for Phoenix in a straight line and covers 121.709 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 Marana that is 85658 (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).
Marana is spread out at 468 people per square mile across 121.709 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 21,767 occupied homes in Marana, 65% heat with natural gas, 0% with heating oil, 31% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0444270, checked 2026-10-19).
Gas heats 65% of Marana against electricity at 31%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Marana has about the Pima County oil share of 0% and 14 points less electric heat than the county's 45% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US04019, checked 2026-10-19).
Marana has 23,432 housing units, 0% built before 1940 and 4% before 1980, with 78% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0444270, checked 2026-10-19).
Marana has 50 points more homes built after 2000 than the county's 28% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US04019, checked 2026-10-19).
The median Marana home was built in 2008 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0444270, checked 2026-10-19) and the median home has 6.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0444270, checked 2026-10-19).
88% of Marana homes are single-family detached, 2% 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=160XX00US0444270, checked 2026-10-19).
With 88% detached houses and 2% in small multi-family buildings, a Marana quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 16% of Marana homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0444270, checked 2026-10-19), the landlord signs the quote in many of them.
Marana has 28 points more detached houses than Pima County overall (60%) and 12 points fewer five-plus-unit buildings than the county's 18% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US04019, checked 2026-10-19).
78% of Marana housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0444270, 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 Marana 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 Marana address before counting it. With 31% of Marana homes already on electric heat and 66% 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 Marana is $112,606 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0444270, 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: 22F.

That 22F figure is the Pima County cold-day number a Marana heat pump is sized against, so ask the installer to show the system's heating output at 22F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 65% of Marana on gas and 31% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Marana home has 6.2 rooms and was built around 2008, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
