Get a Free QuoteOnly ~15% of Vermont homes use natural gas — Vermont Gas Systems serves just the northwest corridor. If you are one of them, a cold-climate heat pump can save $668-$1,000/year. GMP time-of-use rates make the economics even stronger. Here is the honest breakdown.
Last updated: March 2026
If your gas furnace is near end-of-life: Yes. A cold-climate heat pump saves $668/year at standard GMP rates and up to $900/year on GMP time-of-use. With Efficiency Vermont rebates, payback is 6-9 years. If your furnace is newer: The economics are tighter. Gas at $1.65/therm is cheaper than oil or propane, so the savings gap is narrower. Wait for replacement age or consider a dual-fuel approach.
Based on Vermont Gas Systems rate of ~$1.65/therm, GMP standard rate of $0.2146/kWh, 90% AFUE gas furnace, and cold-climate heat pump with average COP of 2.7 (accounting for VT's 7,200 HDD).
| Home Size | Sq Ft | Therms/Yr | Gas Cost | Heat Pump Cost | Annual Savings |
|---|---|---|---|---|---|
| Small | 1,200 | 600 | $990 | $580 | $410 |
| Medium | 2,000 | 950 | $1,568 | $900 | $668 |
| Large | 3,000 | 1,400 | $2,310 | $1,310 | $1,000 |
GMP TOU bonus: On GMP time-of-use rates, off-peak electricity is just $0.1452/kWh. If you shift 70% of heating to off-peak hours (nights and weekends), savings increase by 30-40%. A medium home could save $800-$900/year instead of $668.
Vermont is unique in New England — natural gas serves only a narrow corridor in the northwest. Understanding this context matters for your decision.
We believe in honest advice. There are situations where keeping your gas furnace makes more financial sense right now.
A functioning modern gas furnace (95%+ AFUE) is already efficient. Wait until replacement age and switch then.
If you already have a working AC system, the "free cooling" benefit of a heat pump is less impactful since you are not eliminating an AC purchase.
Address insulation and air sealing first. VT homes average 7,200 HDD — a heat pump in a leaky house will run hard and underperform.
These scenarios make switching from gas to a heat pump a clear financial and practical win in Vermont.
If your furnace needs replacement anyway, the incremental cost of choosing a heat pump is much lower. This is the best time to switch.
A heat pump provides heating AND cooling. If you would buy a furnace plus AC, a heat pump replaces both systems at lower total cost.
GMP off-peak rate is $0.1452/kWh. Running your heat pump during off-peak hours (nights, weekends) cuts operating costs by 30-40% compared to standard rates.
Natural gas leaks cause explosions and produce indoor CO2/CO. A heat pump eliminates all combustion appliances from your home.

Vermont is Climate Zone 6 with among the coldest winters in the lower 48. Here is how cold-climate heat pumps actually perform.
Vermont passed the Clean Heat Standard (Act 18, 2023) — one of the most aggressive electrification policies in the US. Here is what it means for gas customers.
Vermont has a layered incentive structure. Efficiency Vermont provides base rebates; your utility may add more on top.
| Utility | Market Share | Rate | TOU Available | HP Advantage |
|---|---|---|---|---|
| Green Mountain Power (GMP) | ~75% | $0.2146/kWh | Yes — off-peak $0.1452, peak $0.3407 | TOU saves 30-40% on HP operating costs |
| Vermont Electric Cooperative (VEC) | ~15% | $0.2348/kWh | No | Standard rate, still cheaper than gas |
| Burlington Electric Dept (BED) | ~3% | $0.1837/kWh | No | Lowest rate in VT — best HP economics |
$350-$400
Per indoor unit for qualifying cold-climate ductless heat pumps. Stacks with utility incentives.
$200
Per unit on top of Efficiency Vermont rebate. GMP customers get the best combined incentive in VT.
Up to $2,000
GMP provides enhanced incentives for income-eligible households. Contact GMP to check qualification.
Important: The federal 25C energy efficiency tax credit ($2,000 for heat pumps) expired December 31, 2025. All savings calculations on this page reflect current available incentives only.
The typical Vermont homeowner using 950 therms of natural gas per year (~$1,568 at $1.65/therm) saves approximately $668 annually by switching to a cold-climate heat pump. On GMP time-of-use rates with off-peak heating, savings can reach $800-$900/year. Payback is typically 6-9 years after Efficiency Vermont rebates.
Yes. Vermont is Climate Zone 6 with design temperatures of -10 to -20 degrees F depending on location. Modern cold-climate heat pumps from Mitsubishi, Fujitsu, and Daikin operate efficiently down to -13 to -15 degrees F. COP drops from 3.0+ at 30 degrees F to about 1.5-2.0 at -10 degrees F, but they still outperform electric resistance. A dual-fuel backup handles the coldest nights.
With a typical system cost of $14,000-$20,000 and Efficiency Vermont rebates of $350-$400/unit plus GMP incentives of $200/unit, the net cost is roughly $12,000-$18,000. At $668/year in savings (standard rates) or $800-$900 (GMP TOU), payback is 6-9 years. If you also eliminate an AC purchase ($4,000-$6,000), effective payback improves further.
Efficiency Vermont offers $350-$400 per indoor unit for qualifying ductless heat pumps. GMP adds $200 per unit on top of that, and income-eligible households can receive up to $2,000 in additional GMP incentives. The federal 25C tax credit expired December 31, 2025 and is no longer available.
Vermont passed the Clean Heat Standard (Act 18, 2023), requiring fossil fuel sellers — including Vermont Gas Systems — to reduce greenhouse gas emissions. This means VGS must fund and promote clean heat measures like heat pumps. For gas customers, this creates additional incentive pathways and signals that gas costs may rise as compliance costs are passed through.
No. Vermont Gas Systems serves only the northwest corridor of Vermont — primarily Chittenden County (Burlington, South Burlington, Winooski, Essex, Williston), plus parts of Addison County (Middlebury) and some areas toward Hinesburg. Only about 15% of Vermont homes use natural gas. The rest use oil, propane, or wood for heating.
