Heat pumps in Phoenix

Cooling runs most of the year here, so summer efficiency matters more than heating at 5°F. At Arizona prices an efficient heat pump delivers heat for about $18.03 per million Btu, against $18.84 for a high-efficiency gas furnace.

Climate and sizing

Cooling runs most of the year here, so summer efficiency matters more than heating at 5°F. This is a dry climate: look at EER2, the efficiency on the hottest afternoons, as well as SEER2. Whatever the climate, the system should be sized from a room-by-room load calculation (ACCA Manual J), not from the size of the old air conditioner or furnace: an oversized heat pump short-cycles, dehumidifies poorly and costs more.

Degree days: NOAA 1991–2020 climate normals. Climate zone: IECC 2021 (PNNL county list). Housing: Census American Community Survey. Seasonal COP: Seasonal COP for a whole heating season, including electric backup heat and defrost, for a heat pump sized for mild to cold weather. Planning values set slightly below modelled results (Dunsky/CCI 2024) because field studies (RDH for FortisBC; Yukon pilot) came in lower. Above 6,000 degree-days the values rest on one partial-season pilot in Whitehorse, so we use the low end of the band from 7,000 degree-days (Yellowknife).

What heat costs to run in Phoenix

Cost per million Btu of heat delivered into the house, at Arizona's average residential prices from the EIA (electricity for July 2026, gas as an annual average). A typical older house in a cold climate uses 50 to 100 million Btu of heat a year; a house in the South uses far less. Here a heat pump costs less to run than a 95% gas furnace whenever its seasonal COP is above 2.4, which an efficient heat pump reaches in this climate.

Delivered heat cost by fuel in Phoenix
Heating system Cost per million Btu of heat vs cheapest Based on
Cold-climate heat pump $16.10 cheapest seasonal COP 2.8 for this climate
Standard heat pump $18.03 +12% seasonal COP 2.5
Natural gas furnace (95%) $18.84 +17% $1.79 per therm (2025 average)
Electric furnace or baseboards $45.07 +180% 15.4¢ per kWh (July 2026)

Against electric resistance heat (baseboards or an electric furnace), even a standard heat pump cuts the heating bill by about 60%.

Heat pump rebates in Phoenix

Every heat pump program we found for the Phoenix area, with the equipment rule that decides which models qualify. Checked against each program's own page on October 19, 2026. Most utility programs need an AHRI-matched system; check the exact pairing in the AHRI directory before you sign.

SRP Cool Cash A/C and Heat Pump Rebate

Open

SRP (Salt River Project)

Heat pump amountsHeat pump, per ton: single-stage $75; multi-stage $150; variable-capacity $225; inverter-driven mini-split heat pump $225. Limit five rebates per customer.

Equipment ruleMinimum 15.2 SEER2. 'All qualifying equipment must be listed in the AHRI Verified Directories as meeting or exceeding the efficiency minimums.' On split central systems, both the indoor air handler and the condensing unit must be replaced. Single-stage systems need a Manual J load calculation. No ENERGY STAR rule.

Heat pump amountsNo amount on the pages read: 'a set rebate amount which is NOT guaranteed to cover the total project cost'. Our October 12 check gives up to $14,000 per household.

Equipment rule'The rebated model must be ENERGY STAR certified and legal for distribution in the United States at the time of purchase.' Since Sept. 1, 2026, rebates are 'only permitted to replace existing electric appliances and heat pumps', including replacing an existing heat pump with a more efficient one. A heat pump can be added alongside a gas furnace, but 'the program is unable to replace or remove the fossil fuel heat source'. 'Heat pumps will no longer be required to serve as a home's primary heating and cooling…

Other conditions'Anyone who participates in the program will be required to work with an Efficiency Arizona Qualified Contractor'; the rebate is applied to the contractor invoice.

StatusOpen under the new rules. Aug. 28, 2026 was the last day to reserve under the old rules, and new rules apply to reservations from Sept. 1, 2026. Owner-occupants at or below 150% AMI only.

High-Efficiency Electric Home Rebates

The federal rebate (formerly HEAR) pays up to $8,000 toward an ENERGY STAR certified heat pump for income-qualified households, through the state. Since May 29, 2026 it covers only upgrades from existing electric equipment, and the installer must be on the state's contractor list. Arizona's status is in the program list above.
