For most homeowners in Stilwell, Oklahoma and surrounding areas, a heat pump is the more energy-efficient choice for heating and cooling, delivering 2 to 4 times more energy than it consumes. However, a gas furnace still provides fast, reliable heat during our region’s sudden winter cold snaps. The best option for many Oklahoma and Arkansas homes is a dual-fuel system that combines a heat pump with a gas furnace backup, giving you peak efficiency in mild weather and dependable warmth when temperatures drop below freezing.
Key Takeaways
- Heat pumps are 2 to 4 times more efficient than gas furnaces because they transfer heat rather than generate it, making them a strong fit for Oklahoma’s mostly mild to moderate winters.
- Gas furnaces still deliver fast, powerful heat during sudden cold snaps when temperatures plunge below freezing, a reality of living in our part of the country.
- A dual-fuel system pairs a heat pump with a gas furnace backup, giving homeowners the best of both worlds for our region’s unpredictable weather patterns.
- Federal tax credits of up to $2,000 for qualifying heat pumps make 2025 and 2026 an ideal window to consider upgrading your home’s heating system.
How Do Heat Pumps and Furnaces Work Differently?
Understanding the basic mechanics behind each system helps explain why one might be a better fit than the other for your home. The core difference comes down to how each system produces warmth.
How a Heat Pump Heats and Cools Your Home
A heat pump doesn’t create heat. It moves it. In heating mode, the system extracts warmth from the outdoor air and transfers it inside your home using refrigerant and a compressor. In cooling mode, it reverses the process, pulling heat from your indoor air and releasing it outside, working exactly like an air conditioner.
Because a heat pump transfers heat rather than generating it through combustion, it can deliver 2 to 4 times more heating energy than the electricity it consumes. That efficiency is measured by a metric called the Coefficient of Performance (COP). A COP of 3.0, for example, means the system produces three units of heat for every one unit of electricity used.
One of the biggest advantages for Oklahoma homeowners is that a heat pump handles both heating and cooling with a single system. Instead of maintaining a separate furnace and air conditioner, you get year-round comfort from one piece of equipment. To understand how these systems fit into your overall home comfort setup, take a look at how residential HVAC systems work.
How a Gas Furnace Produces Heat
A gas furnace generates heat by burning natural gas (or propane in rural areas) inside a combustion chamber. A heat exchanger captures that thermal energy, and a blower fan distributes the warmed air through your home’s ductwork. Combustion gases are safely vented outside through a flue.
Furnaces are measured by AFUE (Annual Fuel Utilization Efficiency), which tells you what percentage of fuel is converted into usable heat. A furnace with a 95% AFUE rating converts 95 cents of every dollar spent on gas into heat for your home. High-efficiency models reach up to 98% AFUE, but even the best furnaces can never exceed 100% efficiency because they create heat rather than transfer it.

Which System Is More Energy Efficient?
When it comes to raw efficiency, heat pumps have a significant advantage over furnaces in most conditions. But the full picture depends on your local climate and energy prices.
Heat Pump Efficiency Ratings Explained
Heat pump heating efficiency is rated by HSPF2 (Heating Seasonal Performance Factor), while cooling efficiency uses SEER2 (Seasonal Energy Efficiency Ratio). Higher numbers mean greater efficiency. Modern heat pumps commonly achieve SEER2 ratings of 15 to 22 and HSPF2 ratings of 8 to 13.
According to analysis from the Rocky Mountain Institute, heat pumps range from 2.2 to 4.5 times more efficient than an EPA ENERGY STAR gas furnace on an annual basis. In no climate tested was a heat pump less than 200% efficient. Efficiency is highest in mild winter areas like Oklahoma, where the outdoor air holds plenty of thermal energy for the heat pump to capture during most of the heating season.
Modern cold-climate heat pump models have pushed performance even further. According to Trane, their newest variable-speed cold climate heat pumps deliver 100% heating capacity at temperatures down to 5 degrees Fahrenheit and maintain 70% capacity at minus 13 degrees. That kind of technology makes heat pumps a viable primary heating source even in areas that experience occasional deep freezes.
Furnace Efficiency Ratings Explained
Gas furnaces are rated between 80% and 98% AFUE. Standard efficiency models fall in the 80-89% range, while high-efficiency condensing furnaces reach 90-98% AFUE. The higher the AFUE, the less fuel is wasted during operation.
While a 98% AFUE furnace is impressively efficient for a combustion-based system, it still can’t match a heat pump’s ability to deliver 200-400% effective efficiency in moderate temperatures. The furnace’s advantage shows up during extreme cold, when heat pump efficiency naturally declines and the furnace can maintain strong, consistent output regardless of outdoor temperature.
What Does Each System Cost to Install and Operate?
Cost is often the deciding factor for homeowners choosing between a heat pump and a furnace. Both upfront investment and long-term operating costs deserve careful consideration.
Upfront Installation Costs
Heat pumps generally carry a higher initial price tag than furnaces, but they also replace the need for a separate air conditioning system. According to HomeGuide’s 2026 cost data, the average heat pump installation runs $3,800 to $8,200, while a furnace installation typically costs $2,000 to $5,400 or more.
However, that comparison isn’t quite apples to apples. A furnace only heats your home. You’ll still need a separate air conditioner for Oklahoma’s long, hot summers. When you factor in the cost of both a furnace and an AC unit, the total investment often comes close to or exceeds the cost of a single heat pump system that handles both jobs.
Dual-fuel systems, which pair a heat pump with a gas furnace backup, typically add $2,000 to $4,000 on top of the heat pump cost. While the upfront investment is higher, many homeowners find the long-term efficiency savings and comfort benefits justify the expense, especially in a climate like ours.
Monthly Operating Costs in Oklahoma
Natural gas is often cheaper per unit of energy than electricity. But because heat pumps are 2 to 4 times more efficient than furnaces, they frequently cost less to operate even when electricity rates are higher. According to Angi, homeowners in mild to moderate climates can save up to 50% on heating and cooling bills by switching to a heat pump.
Trane reports that energy-efficient heat pumps can save up to 50% on combined heating and cooling bills when replacing an older AC and gas furnace system. For Oklahoma homeowners currently running an aging furnace paired with a 10-plus-year-old air conditioner, the operating cost savings from a modern heat pump can be substantial.
Your actual savings will depend on your local utility rates, home insulation, system size, and how cold your winters get. A qualified HVAC professional can run the numbers based on your specific home and energy costs.

Which System Works Best in Oklahoma and Arkansas Weather?
Oklahoma’s climate creates a unique situation for heating and cooling decisions. Our region doesn’t fit neatly into the “mild climate” or “cold climate” categories that most heat pump vs furnace guides use. We get both extremes, sometimes in the same week.
Why Heat Pumps Thrive in Our Mild Seasons
For roughly 8 to 9 months of the year, Oklahoma and western Arkansas weather falls squarely in the range where heat pumps perform at their best. According to the Oklahoma Climatological Survey, northeastern Oklahoma experiences temperatures of 90 degrees or higher for 60 to 85 days per year, and our winters are generally milder than northern states with only occasional deep freezes.
During spring, fall, and the majority of winter, outdoor temperatures in our area typically stay well above 30 degrees, which is where heat pumps operate at peak efficiency. A heat pump running in these conditions delivers significantly more comfort per dollar than a gas furnace. It also handles summer cooling, eliminating the need for a separate air conditioning system entirely.
For homeowners comparing ductless and traditional configurations, our guide on central air vs mini split systems breaks down the options.
When a Furnace Still Makes Sense
Oklahoma’s weather isn’t always mild. Sudden cold snaps can drop temperatures into the teens or single digits, especially during January and February. During these brief but intense cold stretches, a gas furnace provides fast, powerful heat without any efficiency loss from extreme outdoor temperatures.
A furnace also makes practical sense for homeowners who already have natural gas service and a well-functioning duct system. If your current furnace is relatively new and working well, replacing it with a heat pump may not deliver enough savings to justify the investment right away. In that case, a focused maintenance approach through a seasonal HVAC maintenance checklist can help you maximize the life and efficiency of your existing equipment.
The Dual-Fuel Advantage for Our Region
For many homes in the Stilwell area and surrounding Oklahoma and Arkansas communities, a dual-fuel system offers the ideal balance. This setup pairs a heat pump with a gas furnace in a single integrated system. The heat pump handles heating and cooling during mild and moderate temperatures, where its 200-400% efficiency delivers the biggest energy savings. When temperatures drop below a set threshold, typically around 30 to 35 degrees, the system automatically switches to the gas furnace for backup heating.
This approach gives you the efficiency of a heat pump for 80-90% of the heating season and the reliable power of a gas furnace for the few weeks each winter when extreme cold demands it. You get lower annual energy costs, year-round comfort, and the peace of mind that comes from having two heating sources in one system.

What About Comfort, Safety, and Indoor Air Quality?
Beyond efficiency and cost, the day-to-day experience of living with each system matters. Heat pumps and furnaces deliver comfort differently, and each has distinct implications for indoor air quality and safety.
Humidity and Air Quality Differences
Gas furnaces produce very dry heat. The combustion process removes moisture from the air, which can lead to dry skin, static electricity, and respiratory discomfort during winter months. Many homeowners with gas furnaces end up adding a whole-house humidifier to compensate.
Heat pumps circulate naturally humid air and can actually help maintain more comfortable indoor moisture levels during the heating season. In summer cooling mode, heat pumps also dehumidify your home effectively, which is a real benefit during Oklahoma’s humid months. The result is more consistent year-round comfort without the need for supplemental humidity control.
Both systems benefit from clean ductwork and fresh air filters to maintain good indoor air quality. Regular professional maintenance keeps either system delivering clean, comfortable air throughout your home.
Safety Considerations
Heat pumps run entirely on electricity and involve no combustion, which means there’s no risk of carbon monoxide leaks, gas line issues, or flue blockages. For families with young children, elderly members, or anyone sensitive to indoor air quality concerns, this is a meaningful advantage.
Gas furnaces are safe when properly installed, vented, and maintained. However, they do require a functioning carbon monoxide detector in your home, regular inspection of the heat exchanger for cracks, and proper venting to the exterior. Annual professional maintenance is essential for keeping a gas furnace operating safely throughout the winter.
Are There Tax Credits or Rebates for Heat Pumps in 2025-2026?
Federal incentives have made this one of the best times in recent history to invest in a heat pump system. The Inflation Reduction Act provides a federal tax credit of 30% of installation costs, up to $2,000, for qualifying air-source heat pumps. This credit is available for systems installed through at least 2032.
Americans purchased 21% more heat pumps than gas furnaces in 2023, a shift driven in large part by these financial incentives and improvements in cold-climate heat pump technology.
In addition to the federal credit, many state and local utility programs offer additional rebates that can further reduce your out-of-pocket costs. Oklahoma homeowners should check with their local electric cooperative or utility provider for any current incentive programs. Between federal credits and potential local rebates, it’s possible to offset $2,000 to $4,000 or more of the total installation cost, significantly closing the price gap between a heat pump and a traditional furnace and AC setup.
