Is a heat pump or a gas furnace better in Tucson?
For a home in the Tucson basin, a heat pump is the sensible default. Winters are mild, summers are long, and the same unit that heats also does the cooling you need anyway. A gas furnace still makes sense in some homes, and Mount Lemmon is a different story. Climate Pros Tucson matches you with a licensed pro who can quote both for your house.
Why does the climate favor a heat pump?
Tucson International Airport’s 1991-2020 normals show 3,424 cooling degree days and 1,333 heating degree days, about 2.6 cooling degree days for every heating degree day. Fewer than 12 nights a year drop to 32F or below, and no normal day stays below freezing. The City of Tucson’s code lists a winter design temperature of 35F.
How do the two compare?
| Question | Heat pump | Gas furnace |
|---|---|---|
| Fuel | Electricity (TEP or Trico) | Natural gas (Southwest Gas) |
| Cooling | Same unit cools in summer | Needs a separate AC |
| Cold nights | Handles Tucson basin winters | Handles any cold |
| New gas line | Not needed | Needed if the home has none |
| TEP rebate | Efficient Home Program lists heat pumps | Not listed |
| Southwest Gas rebate | Not applicable | None for furnaces on the 2026 application |
TEP serves most of the metro. Trico Electric Cooperative serves northwest Tucson and Marana south to Green Valley and Sahuarita. Check which one is yours, since plans and programs differ.
What does the rebate picture look like?
As listed by TEP in October 2026, the Efficient Home Program shows up to $720 for a heat pump quality installation through a participating contractor. Southwest Gas’s 2026 Arizona residential rebate application lists no furnace or thermostat rebate. Arizona’s HEAR program, as of October 2026, no longer pays to replace gas appliances with electric ones. Read TEP and Arizona rebates.
What do Arizona homes use now?
Statewide, the EIA’s 2020 survey found 25% of Arizona homes heat mainly with a central heat pump and 55% with a central furnace. Electricity is the main heating fuel in 51% of Arizona homes and natural gas in 36%. Those are Arizona numbers, not Tucson numbers.
When might a furnace still win?
When the home already has gas service and a working duct system, the pro may still suggest a gas furnace paired with an AC. A dual-fuel setup pairs a heat pump with a gas furnace for the coldest nights. Read dual fuel heat pumps in Tucson.
What about Mount Lemmon and Summerhaven?
The picture changes. Normals at Mount Lemmon run about 53 nights a year at or below 32F, and annual heating degree days are 4,024, about three times the airport. A cold-climate heat pump or backup heat is a question for the pro there.
