If you’re replacing an aging heater (or planning ahead before the next cold snap), you’ll probably run into the same question a lot of Concord homeowners ask:

Should I go with a heat pump or a furnace?

Both can keep your home comfortable. The “best” choice depends on your home, your budget, your fuel options, and how you want your system to perform on those chilly Carolina mornings we’re still seeing before spring.

Below is a simple heat pump vs. furnace guide to help you decide. Plus, a few scenarios we see all the time in the Concord area.

Quick answer: Which one should you choose?

A heat pump may be your best fit if you want:

• One system that heats and cools (replacing both your heater and AC)
• High efficiency in typical day-to-day winter temps
• A great option for electric-only homes (no gas line)
• A system that pairs well with modern comfort upgrades and filtration

A furnace may be your best fit if you want:

• Hot, fast heat
• Strong performance during the coldest nights
• A good option if your home already has natural gas and proper venting
• A heating-only upgrade (you’ll still need AC separately)

Not sure? Many homeowners choose a third option:

Dual fuel (heat pump + furnace)

A “hybrid” setup uses a heat pump most of the time, then switches to a furnace when it’s colder outside, often giving you a nice balance of comfort and efficiency.

What is a heat pump?

A heat pump doesn’t “create” heat the way a furnace does. It moves heat, kind of like how a refrigerator moves heat out of your food to keep it cold.

• In winter, it pulls heat from outside air and moves it indoors.
• In summer, it works like an air conditioner, moving heat out of your home to cool it.

That’s why a heat pump is often viewed as a “two-in-one” comfort system: heating + cooling.

Do heat pumps work in winter?

Yes. Even when it’s cold outside, there’s still heat energy in the air. Heat pumps can use it, though efficiency changes with outdoor temperature, and some systems will rely more on backup heat during colder stretches.

What is a furnace?

A furnace creates heat by burning fuel (most commonly natural gas) or using electric heating elements. The warm air is then delivered through your ductwork.

You’ll often hear efficiency discussed with a percentage rating called AFUE (Annual Fuel Utilization Efficiency). In simple terms:

• Higher AFUE generally means less wasted fuel and better efficiency

A furnace does one job extremely well: make warm air quickly. But it’s heating-only, so you’ll still need an air conditioner (or another cooling option) for summer.

Heat pump vs. furnace: side-by-side comparison

Feature	Heat Pump	Furnace
Heating + Cooling	✅ Yes (2-in-1)	❌ No (heating only)
Comfort	Warmer “steady” heat	Hotter “blast” of heat
Efficiency	Often very efficient in milder temps	Very efficient models available (AFUE-based)
Upfront considerations	Equipment + sometimes electrical needs	Gas line/venting + furnace type/efficiency
Cold snaps	May use backup heat more often	Strong performance in very cold weather
Best fit for	Replacing HVAC system, efficiency goals	Homes with gas + preference for hotter heat

Cost & Incentives: What Concord Homeowners Should Know

What affects the installed cost?

Heat pump and furnace pricing varies a lot from home to home. A few things that typically move cost up or down:

• Home size + system sizing: Proper sizing matters for comfort and efficiency (bigger isn’t always better).
• Ductwork condition: Leaky/undersized ducts can limit performance and may need repairs for best results.
• Fuel and venting: Furnaces may require gas line/venting considerations, depending on your setup.
• Electrical needs: Some heat pump installs may require electrical upgrades (panel capacity, wiring, etc.).
• Efficiency level + features: Higher-efficiency systems and upgraded comfort features can raise upfront cost but may improve performance and operating costs over time.
• Dual fuel options: Pairing a heat pump with a furnace can add upfront complexity but can be a great “best of both worlds” solution in the Charlotte metro.

Best next step: an in-home estimate that confirms sizing, ductwork, and your best option (heat pump vs. furnace vs. dual fuel).

Are there rebates or incentives for heat pumps in Concord?

Potentially — and they can make a real difference. Here are a few places Concord-area homeowners often find savings:

• Local/utility rebates:
  • If you’re a City of Concord Electric Systems customer, there’s a published electric heat pump rebate program (eligibility requirements apply).
  • Some homeowners may also qualify for rebates through utility programs like Duke Energy’s home improvement rebate offerings (program rules vary).
  • You can also search by ZIP using the ENERGY STAR Rebate Finder.
• State/federal programs:
  North Carolina’s State Energy Office / DEQ has information on energy-efficiency rebate programs (including heat pumps) that may be available to eligible households.
• Federal tax credit note (important timing):
  ENERGY STAR and the IRS both indicate the Energy Efficient Home Improvement Credit for qualifying air-source heat pumps applies to products purchased and installed between January 1, 2023, and December 31, 2025 (with annual limits). Because this post is being published in 2026, homeowners should verify the current status before relying on any federal credit.

Pro tip: If rebates are a priority, ask for rebate-ready model options during your estimate so you don’t miss an eligibility detail.

What about those cold, damp days in Concord?

Two things are common questions for heat pump homeowners:

1) “Is steam or a loud whoosh normal?”

Sometimes, yes. Heat pumps can run a defrost cycle on cold, damp days to clear frost from the outdoor unit. You might see steam or hear a brief change in sound. That can be normal.

If the unit stays iced over or heat doesn’t return after defrost, that’s when it’s time to schedule service.

2) “Why does my thermostat show AUX heat?”

Many heat pump systems have auxiliary (backup) heat that kicks on when the system needs a boost to keep up with demand. It’s not always a problem. It can be normal during colder weather or if the thermostat is set much higher than the indoor temperature.

The “best of both worlds” option: Dual fuel (hybrid heating)

If you want the efficiency of a heat pump without giving up the power of a furnace on the coldest nights, dual fuel is worth asking about.

A dual-fuel system typically:

• Runs the heat pump during milder weather for efficient heating
• Automatically switches to the furnace when temperatures drop (or when it’s more cost-effective)

For many homes, it’s an excellent upgrade path, especially if you already have a gas furnace and you’re replacing an older central AC.

3 real-world replacement scenarios we see in Concord

Scenario A: “My furnace is older, but my AC still works”

If your AC is in good shape, a furnace replacement may be a straightforward option (depending on the furnace condition and efficiency goals).
If your AC is also aging, consider a heat pump (or dual fuel) so you can upgrade both heating and cooling at once.

Scenario B: “My AC is struggling and my heater is just okay”

This is often a perfect time to consider a heat pump because you’re solving both comfort problems with one new system.

Scenario C: “Some rooms are always colder than others”

Before choosing equipment, you’ll want a contractor who looks at:

• Ductwork condition and airflow
• System sizing (bigger isn’t always better)
• Home comfort issues like insulation gaps or return-air limitations

The right install details matter just as much as the brand on the unit.

FAQs: Heat Pump vs. Furnace

Is a heat pump cheaper to run than a furnace?

Sometimes, especially in moderate weather, but it depends on your home, your system efficiency, and local electric vs. gas costs. An in-home assessment is the best way to estimate real operating costs.

Do heat pumps work when it’s below freezing?

Yes, heat pumps can still work in freezing conditions. Efficiency may drop as outdoor temperatures fall, and backup heat may run more often.

What does “AUX heat” mean?

AUX heat is supplemental heat that helps a heat pump maintain the set temperature during colder weather or high-demand situations. It can be normal, but frequent AUX use can also indicate a sizing, airflow, or performance issue.

Is dual fuel worth it in Concord?

For many homeowners, dual fuel is a great option, especially if you have natural gas and want efficient heating most days, plus strong backup heat on the coldest nights.

How do I know when it’s time to replace my system?

If your system is older, needs frequent repairs, struggles to heat evenly, or your energy bills keep climbing, it’s worth comparing repair vs. replacement options.
