How Arizona homes are heated
Heating fuel in Arizona divides along geography. Statewide, the Census Bureau’s table B25117 for 2020-2024 shows electricity as the main heating fuel in 1,024,213 of 1,924,098 owner-occupied homes, 53.2%, and utility gas in 750,595, or 39.0%. Solar is a measurable fuel here: 27,787 owner homes, 1.4%, report it as their main heat source.
| Heating fuel | Owner-occupied homes | Share | Source |
|---|---|---|---|
| Electricity | 1,024,213 | 53.2% | ACS 2020-2024, B25117 |
| Utility gas | 750,595 | 39.0% | ACS 2020-2024, B25117 |
| Bottled, tank or LP gas | 62,191 | 3.2% | ACS 2020-2024, B25117 |
| Wood | 39,158 | 2.0% | ACS 2020-2024, B25117 |
| Solar energy | 27,787 | 1.4% | ACS 2020-2024, B25117 |
| No fuel used | 12,966 | 0.7% | ACS 2020-2024, B25117 |
| Fuel oil, kerosene, coal and other fuels | 7,188 | 0.4% | ACS 2020-2024, B25117 |
Renters push the electric share higher: across all 2,856,081 occupied homes, table B25040 (2020-2024 ACS) shows 59.9% on electricity and 33.3% on utility gas. For an HVAC buyer, fuel signals the kind of system in place, a heat pump or an air conditioner with electric heat on one side and a gas furnace with a split air conditioner on the other, and so the kind of replacement quote involved. These are housing figures, with no bearing on lead share.
Cooling and heating needs in Arizona
NOAA NCEI’s cooling degree day series for Arizona shows 3,313 for 2025, 250 above the 1991-2020 average of 3,063. Among the 48 states with a statewide series, only one recorded more cooling degree days in 2025.
The heating degree day series shows 1,560 for 2025, well under the 1991-2020 average of 1,919 and 44th of 48. The statewide figure blends the low deserts with the high country, and the county table below shows utility gas ahead of electricity in Pima, Yavapai, Cochise and Coconino counties.
What the figures measure: NCEI sums the daily difference between the mean temperature and 65°F over January to December for the whole state, and the 1991-2020 average is the mean of the 30 yearly totals in the same series.
Arizona HVAC contractor licensing
This section is general information, not legal advice. It summarizes official sources as of October 8, 2026; check the current text of each rule before relying on it.
The Arizona Registrar of Contractors issues separate commercial, residential and dual licenses for each trade. Its license classifications page lists these for heating and air conditioning:
- R-39 Air Conditioning and Refrigeration, Including Solar (residential): install and repair comfort air conditioning systems, including refrigeration, evaporative cooling, ventilating and heating, with or without solar equipment. A new circuit may be added to an existing panel, but not a new service panel.
- C-39 Air Conditioning and Refrigeration (commercial): refrigeration and evaporative cooling systems, plus wet, dry or radiant heating systems, with wet systems limited to 30 PSIG for hot water and 15 PSIG for steam.
- CR-39 Air Conditioning and Refrigeration (dual): the scopes of both the commercial C-39 and the residential R-39R licenses. A CR-79 dual license covers the same work including solar.
- B General Residential Contractor: the general builder scope, under which work on air conditioning systems must be subcontracted to an appropriately licensed contractor.
The page also notes that several older R-39R subclasses, such as warm air heating, evaporative cooling and ventilating, no longer accept new applications. A buyer that routes Arizona jobs to installers can confirm the classification on a contractor’s license with the Registrar. Federal refrigerant certification under EPA Section 608 applies on top of the state license.
Arizona owners and renters for HVAC buyers
Arizona has 1,924,098 owner-occupied homes and 931,983 renter-occupied homes in the 2020-2024 ACS, out of 2,856,081 occupied, per table B25003. Owners pay for and approve system replacements. Tenants report failures, and the landlord or property manager usually chooses the new equipment.
Housing age and the local nature of Arizona energy codes are covered on Arizona window replacement leads.
Arizona counties by owner-occupied homes
Arizona’s ten counties with the most owner-occupied homes, with the share heated by utility gas and by electricity, from the ACS 5-year 2020-2024 county tables B25003 and B25117. These are housing statistics; they do not show where leads come from.
| County | Owner-occupied homes | Heated by utility gas | Heated by electricity | Source |
|---|---|---|---|---|
| Maricopa | 1,127,888 | 34.7% | 61.8% | ACS 2020-2024, B25003 and B25117 (county) |
| Pima | 285,639 | 61.2% | 33.7% | ACS 2020-2024, B25003 and B25117 (county) |
| Pinal | 132,318 | 35.0% | 59.6% | ACS 2020-2024, B25003 and B25117 (county) |
| Yavapai | 83,441 | 51.1% | 27.3% | ACS 2020-2024, B25003 and B25117 (county) |
| Mohave | 75,535 | 33.4% | 56.2% | ACS 2020-2024, B25003 and B25117 (county) |
| Yuma | 56,310 | 19.7% | 71.4% | ACS 2020-2024, B25003 and B25117 (county) |
| Cochise | 36,213 | 53.0% | 29.2% | ACS 2020-2024, B25003 and B25117 (county) |
| Coconino | 32,909 | 48.5% | 17.7% | ACS 2020-2024, B25003 and B25117 (county) |
| Navajo | 29,321 | 28.2% | 18.3% | ACS 2020-2024, B25003 and B25117 (county) |
| Gila | 18,329 | 34.8% | 40.5% | ACS 2020-2024, B25003 and B25117 (county) |
Maricopa County alone holds 1,127,888 owner homes, and 61.8% of them heat with electricity. Pima County, around Tucson, reverses that with 61.2% on utility gas. In the higher counties the two columns leave a large remainder: propane heats 15.2% of owner homes in Yavapai, 13.6% in Navajo and 13.3% in Cochise in the same county data (2020-2024 ACS).
Reading the Arizona numbers for an HVAC plan
Three things stand out when the Arizona figures are read together:
- Cooling sets the pace. At 3,313 cooling degree days in 2025 in the NCEI series, more than double the 1,560 heating degree days, air conditioning repair and replacement dominates the work Arizona installers quote.
- Phoenix and Tucson differ. Maricopa County is 61.8% electric and Pima County 61.2% gas in the ACS county table (2020-2024 ACS), so a buyer covering both metros needs heat pump skills in one and gas furnace skills in the other.
- The license class names the work. The Registrar’s classifications separate residential R-39, commercial C-39 and dual CR-39 air conditioning licenses, and a general residential builder must subcontract air conditioning work, so the classification on an installer’s license shows which jobs it can take.
These readings rest on the official data cited above. None of them is a statement about lead counts or demand in Arizona.
What Arizona HVAC buyers filter on
Arizona HVAC buyers filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary on the same kinds of fields as other home services buyers. Linked to the facts on this page:
- Project type: for example install, replace or repair, for heating or cooling. With this cooling load, air conditioning repair and replacement is where most Arizona buyers start.
- Homeowner status: the 1,924,098 owner-occupied homes are where new systems are approved (ACS 2020-2024, B25003).
- Timeframe: a cooling failure in July is a different request from a replacement planned for the winter.
- ZIP code: buyers choose ZIP codes their crews reach, which can separate Phoenix area work from Tucson or the high country.
When HVAC opens, Arizona buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. The sample HVAC lead lists every field.
Where buyers filter in Arizona
One metro dominates Arizona: Phoenix-Mesa-Chandler has more people than the other five largest metro areas combined. The Census Bureau’s July 1, 2025 estimates for the six largest are below. Once HVAC opens, buyers will be able to set coverage on any ZIP code, inside these areas or outside them.
- Phoenix-Mesa-Chandler: 5,228,938 (July 1, 2025 estimate)
- Tucson: 1,074,685 (July 1, 2025 estimate)
- Prescott Valley-Prescott: 252,552 (July 1, 2025 estimate)
- Lake Havasu City-Kingman: 228,102 (July 1, 2025 estimate)
- Yuma: 224,449 (July 1, 2025 estimate)
- Flagstaff: 144,368 (July 1, 2025 estimate)
