One thing these figures leave out
A heat pump cools as well as heats. If your air conditioner is also near the end of its life, you are replacing two machines with one, and the premium above overstates what you would actually spend. That is the situation where a heat pump wins most clearly, and it is worth checking the age of your AC before deciding.
Common questions
How much does a heat pump cost in Arizona?
Between about $7,000 and $10,600 installed for a 3-ton standard system in a 1,800 square foot home. That is roughly $3,700 more than replacing a gas furnace like for like.
Is a heat pump worth it in Arizona?
On running cost, yes — about $249 a year less than gas here. Against the $3,700 it costs extra to install, that is roughly 14.9 years to break even, which is a long time to wait.
Do I need a cold-climate heat pump in Arizona?
Probably not. Arizona sees about 25 freezing nights a year, which a standard air-source heat pump handles without much backup heat. Paying for a cold-climate model here is buying capacity you would rarely use.
