For most Tucson homes, a heat pump is the better fit when you’re replacing both your heating and cooling, because one system handles both and our mild winters play to its strengths. A gas furnace still makes sense when your AC is fairly new, you already have gas service and only the furnace needs replacing.
Signature Heating, Cooling & Plumbing is a veteran-owned, family-owned HVAC company in Tucson, and we install both heat pumps and gas furnaces. That means our recommendation comes down to what fits your home, your existing equipment and your budget. If you’re already planning a new system, our heater installation page covers what the process looks like.
Why do heat pumps work well in Tucson?
Tucson’s winters are mild compared with most of the country. Overnight lows occasionally dip near freezing, but daytime temperatures usually recover quickly, and the heating season is short. Heat pumps are most efficient in exactly those conditions.
Our cooling season is the opposite: long, hot and demanding. In a Tucson home, a heat pump spends far more of its life cooling than heating, so it’s really an air conditioner that can also run in reverse. That’s why the decision often starts with the condition of your AC.
How does a heat pump work?
A heat pump moves heat rather than creating it by burning fuel. In winter, it pulls heat from the outdoor air and transfers it inside. In summer, it reverses direction and moves heat out of your home, working just like a central air conditioner.
Because it moves heat instead of generating it, a heat pump typically delivers two or more units of heat for every unit of electricity it uses in mild weather. That makes it far more efficient than electric resistance heating, such as electric furnaces or baseboard heaters.
What is the difference between a heat pump and a gas furnace?
| Feature | Heat pump | Gas furnace |
| Heating | Yes | Yes |
| Cooling | Yes, same system | Needs a separate AC |
| Energy source | Electricity | Natural gas or propane |
| Combustion | None | Yes, requires venting and CO safety measures |
| Supply air feel | Warm, steady, longer run times | Hotter air in shorter bursts |
| Best fit | Homes replacing both heating and cooling, or homes without gas | Homes with gas service and an AC that still has useful life |
Neither option is automatically cheaper to run in every Tucson home. Your electric and gas rates, how much you heat and whether you’re replacing the AC at the same time all shape the long-term cost.
When is a heat pump the better choice?
Your AC needs replacing too
This is the strongest case for a heat pump. Instead of buying a new air conditioner and keeping a separate furnace, you replace both with a single system. If you’re still deciding whether your AC is worth fixing, our guide on whether to repair or replace your AC can help.
Your home doesn’t have gas service
In an all-electric home, a heat pump provides efficient heating without adding a gas line.
You currently heat with electric resistance
Electric furnaces and baseboard heat use a lot of electricity. Switching to a heat pump can noticeably lower winter energy use because it moves heat rather than generating it directly.
When does a gas furnace make more sense?
Your AC is still relatively new
If your air conditioner has plenty of life left and only the furnace has failed, replacing the furnace alone is usually more practical than retiring a working AC early.
You already have gas service and like furnace heat
An existing gas line makes a furnace replacement more straightforward. A furnace also produces hotter supply air than a heat pump, which some homeowners prefer on cold mornings.
Your budget calls for replacing one piece of equipment
Replacing a single failed furnace usually costs less upfront than replacing both heating and cooling equipment. If your AC is also nearing the end of its life, though, it’s worth comparing the combined cost of doing both jobs separately over the next few years.
Is dual fuel worth it in Tucson?
A dual-fuel system pairs a heat pump with a gas furnace. The heat pump handles most of the heating, and the furnace takes over when it’s colder or when gas is the cheaper option at the moment.
In most Tucson homes, the heating load is small enough that a heat pump alone does the job, so the added equipment cost of dual fuel is harder to justify. It can make sense for homes with unusually high heating needs or for homeowners who want to keep existing gas equipment in service. We can help you decide whether it’s worth it for your home.
What efficiency ratings should you compare on a heat pump?
A heat pump carries three ratings worth checking:
- SEER2 measures cooling efficiency across a typical season.
- EER2 measures cooling efficiency at a 95°F outdoor temperature, which makes it especially useful in Tucson.
- HSPF2 measures heating efficiency.
Because a Tucson heat pump spends most of its time cooling, SEER2 and EER2 usually matter more here than HSPF2. Federal minimums currently require split-system heat pumps to meet at least 14.3 SEER2 and 7.5 HSPF2 nationwide. Arizona is part of the Department of Energy’s Southwest region, which adds EER2 requirements for central air conditioners.
Why does sizing matter for a heat pump in Tucson?
A heat pump has to handle both our intense summer cooling load and our milder winter heating load, and in Tucson the cooling side almost always drives the size. The right capacity comes from a load calculation that looks at your home’s insulation, windows, orientation and ductwork, not square footage alone. Our guide on what size AC you need for a Tucson home explains how that calculation works, and the same process applies to heat pumps.
Is there still a federal tax credit for a heat pump in 2026?
No. The federal Section 25C Energy Efficient Home Improvement Credit, which offered up to $2,000 for qualifying heat pumps, doesn’t apply to equipment placed in service after December 31, 2025.
Are there heat pump rebates in Tucson?
Yes. Tucson Electric Power’s Efficient Home Program offers instant rebates on qualifying high-efficiency heat pumps and air conditioners installed through participating contractors. Rebate amounts and requirements change, so confirm current eligibility before you sign an agreement.
Income-eligible households may also qualify for Efficiency Arizona, a state-run rebate program. Under rules that took effect September 1, 2026, the program no longer covers replacing a gas system with an electric one, so rebates now apply only when replacing existing electric equipment, such as an older heat pump or electric resistance heat.
What should you ask before choosing a heating system?
Before you approve a replacement, ask your contractor:
- Can my current AC and furnace be replaced with one heat pump system?
- Can my electrical panel handle the new equipment?
- How was the system size determined?
- Which rebates could this project qualify for?
- Does my ductwork need repairs or changes?
What safety considerations apply to gas furnaces?
Gas furnaces burn fuel, so proper venting, annual inspections and working carbon monoxide detectors are essential. If you choose a furnace or keep your existing one, schedule regular heater maintenance and test your CO detectors every season.
Frequently Asked Questions
Do heat pumps work well in Tucson?
Yes. Tucson’s mild winters are ideal conditions for heat pump heating, and the same system handles our long cooling season. It still needs to be sized and installed correctly for your home.
Is a heat pump cheaper to run than a gas furnace in Arizona?
It depends on your electric and gas rates and how much heating your home needs. A heat pump tends to be most cost-effective when you’re replacing both your AC and furnace at the same time.
Why does heat pump air feel cooler than furnace air?
A heat pump delivers warm air at a lower temperature than a furnace and runs longer cycles to hold the thermostat setting. The house stays just as warm, but the air coming from the vents won’t feel as hot.
Do heat pumps produce carbon monoxide?
No. An electric heat pump doesn’t burn fuel, so it doesn’t create carbon monoxide. Gas furnaces do, which is why they need proper venting and working CO detectors.
Not Sure Which System Fits Your Home?
We’ll help you compare both options honestly, based on your equipment, your home and your budget.
