Heat Pump vs Gas Furnace Efficiency & Operating Math · Facilities Matrix
Field Verified

## The decision matrix

| Factor | Heat pump wins | Furnace wins |
| --- | --- | --- |
| Climate zone | Zones 1-5 (south, mid-Atlantic, Pacific Northwest) | Zones 6-7 (Northeast, Midwest, Mountain) |
| Gas price | > $0.85/therm | < $0.85/therm |
| Electric price | < $0.16/kWh | > $0.20/kWh |
| Existing heating | Replacing electric resistance / oil | Replacing gas furnace one-for-one |
| Service capacity | 200A+ electric service | 100A service (no panel upgrade needed) |
| State rebate | HEEHRA / Mass Save / NYSERDA available | No rebate available |
| AC needed too? | Yes (heat pump = heating + cooling in one unit) | No (heat-only need) |

## Annual operating cost (the number that drives the math)

| System | Efficiency | Annual energy (avg 2,200 sqft, mod climate) | Annual cost |
| --- | --- | --- | --- |
| Cold-climate heat pump (COP 3.0) | HSPF2 10.5 | ~5,800 kWh | **$928** |
| Standard heat pump (COP 2.5) | HSPF2 8.5 | ~7,000 kWh | $1,120 |
| 96% AFUE gas furnace | 96 AFUE | ~880 therms | $1,144 |
| 80% AFUE gas furnace | 80 AFUE | ~1,050 therms | $1,365 |
| Electric resistance furnace | 100% (resistive) | ~21,000 kWh | $3,360 |

Assumes $0.16/kWh electric, $1.30/therm gas, 60M BTU annual heating load. Cold-climate heat pump beats 96% gas furnace by ~$216/yr at these rates. Margin shrinks at $0.20/kWh and $1.00/therm, gas wins at those rates by ~$50/yr. Margin widens at $0.12/kWh, heat pump wins by ~$400/yr.

## Install cost reality

| System | Equipment | Install labor + ductwork | Electrical / panel work | Total installed |
| --- | --- | --- | --- | --- |
| Cold-climate heat pump (3-5 ton) | $4,000-$7,000 | $1,500-$3,500 | $0-$3,500 (panel upgrade if needed) | **$5,500-$12,000** |
| 96% AFUE gas furnace + new AC | $3,500-$6,000 | $1,000-$2,500 | $0 | $4,500-$8,500 |
| Hybrid (heat pump + gas furnace) | $6,500-$10,000 | $2,000-$3,500 | $0-$3,500 | $10,000-$14,000 |

## Cold-climate ratings, the spec that matters

Manufacturer marketing splashes the lowest operating temp like it's the whole story. It isn't. The spec that matters is **rated heating capacity at 5°F**, anything above 80% of nameplate is acceptable. Below 80%, the compressor is working past its design envelope and the unit is throwing electric resistance heat at the problem (which is what you bought a heat pump to avoid). Mitsubishi FX Hyper-Heat, Daikin Aurora, and Fujitsu XLTH all hit 100% nameplate at 5°F. Cheaper "cold-climate" units often hit 65-75% at 5°F, they'll run, but they're cycling through electric-strip backup and your bill reflects it.

## The 25C credit is gone, what's left in 2026

The Inflation Reduction Act **Section 25C heat pump federal credit expired December 31, 2025**. State and utility rebates remain, and in many states are more generous than the old federal credit:

- **HEEHRA point-of-sale rebates**, up to $8,000 for income-qualified households on whole-home heat pump installs (state-administered, IRA-funded)

- **Mass Save** (Massachusetts), up to $10,000 for whole-home heat pump installs

- **NYSERDA** (New York): Clean Heat program rebates $1,000-$3,500

- **Efficiency Maine**, up to $4,000 ductless heat pump rebate

- **PSE&G / Eversource / ConEd**, varied utility programs $500-$2,500

Check [DSIRE](https://www.dsireusa.org/) for your specific ZIP before any install conversation.

## The hybrid (dual-fuel) option

Heat pump as primary heat above ~35°F, gas furnace as backup below. Captures the operating-cost savings of a heat pump in shoulder seasons (which is most of the year in mixed climates) plus the no-failure heat of gas in deep cold. Premium install ($10K-$14K) but **lowest annual operating cost in mixed climates**, typically beats heat-pump-only by $150-$300/yr and gas-only by $200-$400/yr.

Worth considering specifically in: Mid-Atlantic, Midwest with moderate winters, mountain west. Less compelling in: Deep South (gas barely runs) or Northeast/upper Midwest (cold-climate heat pump alone now competitive).

## FAQ

Is a heat pump cheaper to run than a furnace?

Yes in mild climates. Above $0.85/therm gas pricing and below $0.16/kWh electric, heat pumps win. Cold-climate-rated units required for northern climates.

Install cost difference?

Heat pump: $5,500-$12,000. Furnace: $4,500-$8,500. Delta: $1,000-$3,500. Hybrid: $10,000-$14,000.

Will a heat pump work in cold climates?

Cold-climate models (Mitsubishi FX, Daikin Aurora, Fujitsu XLTH) run continuously to -13°F. Verify rated heating capacity at 5°F, above 80% nameplate is acceptable.

Did the heat pump tax credit expire?

Federal 25C: yes, December 31, 2025. State/utility rebates remain. Check DSIRE.

What's a hybrid (dual-fuel) heat pump?

Heat pump + gas furnace backup. Heat pump above ~35°F, gas below. Premium install, lowest operating cost in mixed climates.

## The bottom line

If you're in a mild climate (Zones 1-4) replacing AC plus heat: cold-climate heat pump wins on operating cost and avoids the gas-line install. If you're in deep cold (Zone 6-7) on a tight budget: 96% AFUE gas furnace beats a marginal heat pump install. If you're in a mixed climate and can afford it: hybrid dual-fuel is the operating-cost winner. The right answer depends on your zip code, your gas-vs-electric rate ratio, and whether your state offers HEEHRA-class rebates. Stop deciding from the SERP. Get three install quotes that include both options.
