Upfront Cost Comparison
What you'll actually pay to buy and install each system.
| Gas Furnace + AC | Heat Pump | |
|---|---|---|
| Equipment | $3,500 – $7,500 | $4,000 – $8,000 |
| Installation labor | $3,000 – $6,000 | $3,000 – $6,000 |
| Total installed | $6,500 – $13,500 | $7,000 – $14,000 |
| Federal tax credit | — | Up to $2,000 (30%) |
| Net cost after credit | $6,500 – $13,500 | $5,000 – $12,000 |
| Typical lifespan | 15 – 20 years | 15 – 20 years |
Note: Gas furnace + AC requires two separate units. A heat pump replaces both in one system. The federal 25C tax credit applies to heat pumps meeting efficiency requirements.
Annual Operating Costs by State
Based on average residential utility rates and a typical 2,000 sq ft home with moderate insulation.
Beyond Cost
Operating cost isn't the only factor. Here's what else to consider.
Environmental impact
A heat pump produces zero on-site emissions. As the grid gets cleaner, your heat pump gets greener automatically. A gas furnace burns fossil fuel in your home for as long as you own it.
Comfort
Heat pumps deliver lower-temperature air more continuously, avoiding the blast-of-hot-air-then-nothing cycle of a furnace. Many homeowners report more even temperatures room to room. Mini-splits allow per-room temperature control.
Maintenance
Heat pumps need annual filter changes and occasional coil cleaning. No combustion means no carbon monoxide risk, no gas leak risk, and no annual furnace inspection. Overall maintenance costs are similar to a central AC unit.
Noise
Modern inverter-driven heat pumps run at 40-55 dB outdoors — about the level of a quiet conversation. Indoor units are typically quieter than a furnace blower. Older or budget models can be louder.
Resale value
Zillow data suggests homes with heat pumps sell for 4-7% more than comparable homes. Buyers increasingly value energy efficiency, and a heat pump signals a modern, well-maintained home.
Frequently Asked Questions
Is a heat pump cheaper than gas?
For upfront cost, they're roughly the same once you factor in the federal tax credit — and the heat pump replaces both your furnace and AC. For operating cost, it depends on your local gas and electricity rates. In most of the US, the combined heating + cooling cost of a heat pump is lower. In areas with very cheap gas and expensive electricity, gas can be cheaper for heating alone.
How much does a heat pump cost to run per month?
For a typical 2,000 sq ft home, expect $80-$200/month for heating in winter and $50-$150/month for cooling in summer, depending on your climate and electricity rate. Spring and fall months are much cheaper since the heat pump barely runs. Annual operating cost is typically $1,000-$2,500 for both heating and cooling combined.
Can a heat pump replace a gas furnace?
Yes. A ducted heat pump connects to your existing ductwork and replaces both the furnace and AC. In cold climates (zones 5-7), many homeowners keep the gas furnace as backup in a dual-fuel configuration — the heat pump handles most of the work and the furnace kicks in only on the coldest days. In zones 1-4, a heat pump can fully replace the furnace with no backup needed.
