Why Oklahoma's Climate Matters for This Decision
The heat pump vs. furnace debate has a different answer depending on where you live. In Minnesota or North Dakota, where winters regularly drop to -20°F for weeks, a gas furnace is the clear choice. Heat pumps lose efficiency as temperatures plummet, and in extreme sustained cold they can't keep up without expensive backup electric resistance heat.
Oklahoma is a different story. Our winters are mild to moderate — Oklahoma City averages January lows around 28°F and highs around 48°F. Days below 20°F are uncommon, and sustained extreme cold is rare (though the 2021 ice storm reminded us it can happen). On most winter days, a heat pump operates in its most efficient temperature range: 25–50°F outdoors.
Meanwhile, Oklahoma summers are brutal. We get 90+ days per year above 90°F, and 100°F+ stretches are normal. A heat pump replaces both your furnace AND your air conditioner — one system handles year-round comfort. In a climate where you need serious cooling capacity for 5+ months, that integrated approach has real long-term advantages.
How a Heat Pump Actually Works
A heat pump doesn't generate heat — it moves it. In summer, it works exactly like a central AC: it pulls heat from inside your home and dumps it outside. In winter, it reverses the process: it extracts heat from the outdoor air (even cold air contains heat energy) and moves it inside.
That's why heat pumps are so efficient for heating: instead of burning fuel to create heat — which tops out around 95–98% efficiency for the best gas furnaces — a heat pump moves 2–3 units of heat for every unit of electricity it consumes. A heat pump running at a COP (coefficient of performance) of 2.5 is 250% efficient by conventional measures. No combustion system can match that in mild conditions.
On a 35°F Oklahoma winter day, a modern heat pump might deliver heat at 250–300% efficiency. A top-tier gas furnace delivers at 95–98%. Even accounting for electricity vs. natural gas price differences, the heat pump often wins on monthly operating cost at these temperatures — which represent the majority of Oklahoma winter days.

The Best of Both: Dual-Fuel Systems
There's a third option that's particularly well-suited for Oklahoma: the dual-fuel system (also called a hybrid heat pump). It pairs a heat pump with a gas furnace — the system automatically chooses the most efficient heating method based on outdoor temperature.
In practice: when it's 40°F outside, the heat pump handles heating at 250–300% efficiency. When temperatures drop below a configurable setpoint (typically 25–35°F), the gas furnace kicks in and handles the load more economically than electric resistance backup heat.
For Oklahoma homeowners who want maximum efficiency in our mild winters but peace of mind during ice storms, dual-fuel is worth a serious look. You get heat pump efficiency for 90%+ of heating hours, and gas furnace reliability for the brutal 10%.
Heat pump systems (including dual-fuel setups) may qualify for up to $2,000 in federal tax credits under the Inflation Reduction Act. Ask Kent about current eligibility — the rules change and the installation details matter for qualifying.
Kent's Honest Take
“For most Oklahoma homeowners — especially if you're replacing both AC and heat at the same time — I lean toward a heat pump. Modern cold-climate models stay efficient down to 5–10°F, our winters are mild enough to run in optimal range most of the time, and you get one system instead of two.
That said, I don't push heat pumps on everyone. If your furnace is 5 years old and your AC died, replace the AC — not the whole system. If you lived through February 2021 and you want the reliability insurance of a gas furnace backup, talk to me about dual-fuel.
Call me and tell me your actual situation. I'll give you a straight answer — not the one that maximizes my margin.”
