It depends on your quotes

It depends on your quotes. A heat pump saves about $180 a year to run, so it comes out ahead over 15 years if its quote is no more than $2,700 above the quote for a new furnace and AC.

Heat pump still wins up to $14,000 Typical quote for either, about $11,400
Quotes before rebates. The shaded part of the bar is where a heat pump quote still has the lower 15-year cost.

What this is based on

  • Electricity: Mohave Electric Cooperative, Inc.'s average residential price in AZ (EIA), $0.112/kWh; the winter price of extra kWh is estimated at $0.109/kWh. Enter your own rate for a closer answer.
  • Weather: Bullhead City (1,100 heating and 4,503 cooling degree days a year, 1991-2020).
  • Gas: Arizona average residential price over the last five winter months (EIA), $1.78/therm.
  • Arizona HVAC installer wages are 3% below the U.S. median (BLS), so installed prices are scaled by 0.99.
  • Energy use for heating and cooling:
    • New gas furnace + new AC: 5,003 kWh and 105 therms a year for heating and cooling
    • Heat pump (replaces both): 5,105 kWh a year for heating and cooling
    • High-efficiency cold-climate heat pump: 3,734 kWh a year for heating and cooling

Rebates

  • APS ended residential HVAC rebates on January 1, 2026. Efficiency Arizona's income-based HEAR rebates no longer cover gas-to-electric switches (since September 1, 2026). The federal 25C tax credit ended with 2025 installs.

How Mohave Electric Cooperative, Inc.'s rates change the answer

Mohave Electric Cooperative, Inc.'s electricity price for a typical home is 28% below the Arizona average ($0.112 vs. $0.155 per kWh). A heat pump moves your heating from gas to electricity, so the electricity price is the biggest single factor: calculators that use a state average can get the answer wrong for your utility. At these prices, a heat pump is cheaper to run for a typical home here.

How we calculate this

Heating and cooling need

Your home's yearly heating and cooling need comes from 1991-2020 NOAA climate normals for the nearest weather station, scaled by floor area and insulation level. If you know last winter's gas use, compare it with the therms in the energy-use list above.

Equipment efficiency

New furnace 95% AFUE; new AC SEER2 13.4; standard heat pump SEER2 15.2 / HSPF2 7.8; high-efficiency cold-climate heat pump SEER2 21.5 / HSPF2 10.6. Heat pump efficiency falls as it gets colder, and in cold months part of the heat comes from backup electric strips (or your old furnace, if you keep it). Existing equipment is assumed to be a 15-20 year old 80% furnace or SEER2 9.5 AC.

Installed costs

Installed prices vary a lot, so we show a typical price and a range for a home of about 1,800 sq ft with existing ductwork, scaled for larger or smaller homes: furnace and AC together $9,000–$14,000; furnace alone $3,800–$7,000; AC alone $4,500–$9,000; standard heat pump $8,000–$15,000; high-efficiency cold-climate heat pump $11,000–$20,000; electrical panel upgrade, if needed, $1,500–$4,000. These are national figures drawn from published studies and program data (NESCAUM / Energy Solutions, Heat Pumps in the Northeast and Mid-Atlantic: Costs and Market Trends (October 2024); Rewiring America, Upfront cost of home electrification (March 2024); EIA, Updated Buildings Sector Appliance and Equipment Costs and Efficiencies (2023)). The most useful number here is how much more a heat pump can cost than a like-for-like quote and still come out ahead: get quotes for both and compare.

Labor and rebates

Half of each installed price is treated as labor and scaled by the state's median HVAC installer wage relative to the U.S. median (U.S. Bureau of Labor Statistics). Listed rebates are subtracted when the box is ticked; per-ton rebates assume about one ton of capacity per 600 sq ft. Rebates change often and have eligibility rules, so confirm with the program before you buy.

Not included

Financing, maintenance (similar for all options), local town rebates, and changes in energy prices over time.
