For many homes in Apex and the Triangle, a heat pump is a better choice than a furnace. Our climate sits in climate zone 4A: mild enough that a heat pump handles both heating and cooling efficiently for most of the year. A gas furnace paired with a separate AC still works fine, but a heat pump does both jobs in one system. The main exception is older homes with existing gas service and poor insulation, where a furnace or a dual-fuel setup may still make more sense for the coldest weeks of winter.
Here's how a heat pump actually works, stripped of the technical jargon. In summer, it moves heat from inside your home to outside, exactly like an air conditioner, because it is one. In winter, it reverses the process and pulls heat from outdoor air into your home. Yes, there's heat in 35°F air. There's heat in 20°F air too, just less of it. The system uses refrigerant and a compressor to concentrate that outdoor heat and deliver it inside. It doesn't burn anything in the house: no combustion and no carbon monoxide from the heat pump itself.
The efficiency numbers tell the real story. A gas furnace converts fuel to heat at 80-98% efficiency, depending on the model. A heat pump doesn't generate heat. It moves it. That process can deliver 2-3 times more heating energy than the electrical energy it consumes. In HVAC terms, a modern heat pump operates at 200-300% efficiency in mild conditions. On a typical mild Triangle winter day, a heat pump is often cheaper to run than a gas furnace, though it depends on your electric and gas rates.
The efficiency advantage shrinks as temperatures drop. As it gets colder, a standard heat pump has to work harder to pull heat from the air, and its output and efficiency fall. Cold-climate models hold up much better. In central North Carolina, the coldest hours of the year are a small share of the heating season, so for most of the winter a heat pump is doing the work efficiently.
When temperatures do drop into that range, you have two options. The first is auxiliary electric heat strips built into the air handler. These are electric heating elements that supplement the heat pump's output during extreme cold. They work, but they're expensive to run. The good news is they're meant to kick in only during the coldest hours. The second option is a dual-fuel system: a heat pump paired with a gas furnace. When temperatures drop below a set point, the system automatically switches from the heat pump to the gas furnace. You get heat pump efficiency for most of the winter and gas heat for the cold snaps. Dual-fuel systems cost more upfront but cover both ends.
A new heat pump system for a typical Apex home runs $5,500-$13,000+ installed, depending on size, efficiency, and brand. That's comparable to buying a new AC and furnace together, except you're getting one system that does both jobs. How the operating costs compare depends on your Duke Energy and gas rates, and we'll walk you through the numbers for your home.
On incentives: the federal energy efficiency tax credit for heat pumps ended for equipment installed after December 31, 2025. Utility rebates may still be available for qualifying systems. We'll tell you what's current when we give you your estimate.
Many newer subdivisions in Apex, Holly Springs, and Fuquay-Varina were built with heat pump systems. Builders often chose them because they're simpler to install where there's no gas line, and the Triangle climate suits them. If your home already has a heat pump and it's reaching the end of its life, replacing it with a newer model is usually the right call. Today's heat pumps are more efficient than models from 10 years ago, and many use variable-speed compressors that adjust output to match conditions rather than cycling on and off.
Our NATE-certified techs install, repair, and maintain heat pump systems daily across Apex, Cary, Raleigh, Durham, Holly Springs, and Fuquay-Varina. We provide free in-home estimates where we evaluate your current system, discuss your heating and cooling priorities, and give you straightforward options. If a heat pump makes sense, we'll explain why. If your situation genuinely calls for a furnace or dual-fuel setup, we'll tell you that too. Financing is available to make the upgrade manageable.
