What Arizona Residents Should Know

Arizona falls in IECC climate zone 2B with 1,500 heating degree days per year — well below the national average. With an average heating COP of 3.5, heat pumps in Arizona operate at high efficiency, producing 3.5 units of heat for every unit of electricity consumed.

At Arizona's natural gas price of $1.30 per therm and electricity at $0.138 per kWh, a heat pump can save roughly $3 per year in heating costs compared to a gas furnace. Heat pumps also provide cooling in summer, potentially replacing both your furnace and central AC in a single system and eliminating separate maintenance contracts.

A heat pump also replaces your air conditioner, and Arizona's 4,000 cooling degree days make that dual-function value real: one system handles both seasons, so you retire a separate AC unit and its maintenance along with the furnace. For homes with an aging furnace-and-AC pair, replacing both at once is usually where a heat pump makes the strongest financial case in Arizona.

Arizona residents can access up to $725 in state rebates and incentives for heat pump installations. With the federal 25C credit having ended December 31, 2025, these state and utility programs are now the primary way to reduce the upfront installation cost, which typically ranges from $4,000 to $8,000 depending on system size and complexity.
