The home heating landscape is experiencing a seismic shift in 2026. After heat pumps outsold gas furnaces by 26% in 2025, the era of electric heating has officially arrived. But there’s a critical twist: federal tax credits expired December 31, 2025, fundamentally changing the economic calculus for millions of homeowners.
This isn’t just about efficiency ratings or equipment costs. It’s about navigating volatile natural gas prices, understanding real-world cold climate heat pump efficiency, and making a decision that aligns with your home’s infrastructure, budget priorities, and long-term goals. Whether you’re in Minnesota’s brutal winters, Tennessee’s mild climate, or Hamilton, Ontario’s variable conditions, this guide delivers the data you need.

The Inflation Reduction Act’s Section 25C tax credits, which offered up to $2,000 (30% of costs) for heat pump installations and up to $600 for high-efficiency gas furnaces, expired December 31, 2025.
This removes one of the biggest financial incentives that made heat pumps competitive on upfront cost. State and local rebates remain available in many areas, but the federal subsidy that pushed heat pump adoption nationwide is gone.
In Canada, programs like the Greener Homes Grant continue, offering up to $10,000 for oil-to-heat-pump switches.
Starting December 18, 2028, all new residential gas furnaces must achieve a minimum 95% AFUE rating.
This effectively bans non-condensing furnaces and will save consumers an estimated $1.5 billion annually while reducing carbon emissions by 332 million metric tons over 30 years. If you’re buying a gas furnace in 2026, you’re investing in technology that will be obsolete in two years unless it’s already high-efficiency.
For the second consecutive year, heat pump sales exceeded gas furnace sales by 26% in 2025 and 25% in the first half alone.
In Canada, over 840,000 heat pumps have been installed with aggressive targets for 2030.
Nearly half of New Brunswick homes now rely on heat pumps. The North American cold climate heat pump market alone was valued at $3.25 billion in 2025 and is projected to reach $3.57 billion in 2026.
Heat Pump: An electric system that transfers heat from outside air (even in freezing temperatures) into your home using a refrigerant cycle and compressor. In summer, it reverses the process for air conditioning. Key components include an outdoor condenser unit, indoor air handler or evaporator coil, and refrigerant lines.
Gas Furnace: Burns natural gas in a combustion chamber to generate heat through a heat exchanger, then distributes warm air via ductwork using a blower. Requires natural gas lines and proper venting for combustion gases.
SEER2 (Seasonal Energy Efficiency Ratio 2): Measures cooling efficiency as total heat removed (in BTU) divided by electricity used over an entire season. Simulates real-world conditions from 65°F to 104°F.
Minimum standard: 14.3 SEER2 for split-system heat pumps. Premium models reach 22 SEER2.
HSPF2 (Heating Seasonal Performance Factor 2): Measures heating efficiency similarly to SEER2 but for the heating season.
Minimum standard: 7.5 HSPF2. High-efficiency models: 9+ HSPF2. Premium models reach 10.5+ HSPF2.
AFUE (Annual Fuel Utilization Efficiency): Measures what percentage of gas burned becomes heat for your home. An 80% AFUE furnace wastes 20% of fuel up the chimney.
Current minimum: 80% nationwide. High-efficiency models: 95-99% AFUE.
By 2028, all new furnaces must meet 95% AFUE minimum.
Here’s the fundamental difference: gas furnaces are limited by thermodynamics to a maximum 99% efficiency (you can’t extract more energy than you burn). Heat pumps, however, move heat rather than generate it, achieving 200-450% efficiency (COP of 2.0-4.5). This means for every unit of electricity consumed, a heat pump delivers 2 to 4.5 units of heating energy.
In practical terms: if you’re heating a 1,800 sq ft home in a cold climate with modern insulation, switching from a gas furnace to a heat pump can save approximately $650 annually. In Maine, field data shows heat pumps cost about 60% less to operate than propane, 53% less than oil, and 11% less than natural gas.
The most persistent misconception about heat pumps is that they don’t work in cold climates. This was true for models from the 1990s and early 2000s. It’s categorically false in 2026.
Modern cold climate heat pumps maintain 100% heating capacity at 5°F and operate efficiently down to -13°F to -23°F.
The Lennox SL22KLV achieves 21.10 SEER2, 13.2 EER2, and 10.50 HSPF2 while operating reliably down to -20°F… delivering 150% higher efficiency at cold temperatures compared to standard heat pumps.
Top 2025 cold climate models include:
Field testing confirms the lab results. In Kake, Alaska, heat pumps save approximately $523 annually versus fuel oil. Lab-backed tests north of the Arctic Circle validate performance in extreme conditions.
The Trade-off: What Gas Furnaces Still Do Better
Gas furnaces excel in three specific scenarios:

If climate impact factors into your decision, the numbers are unambiguous: heat pumps reduce heating-related emissions by 45-72% compared to gas furnaces in typical U.S. homes. In states like Florida, Michigan, and California, lifetime emissions reductions can reach 93%.
This advantage holds even in states with coal-heavy electricity grids. Heat pumps reduce emissions by at least 20% compared to gas boilers regardless of grid makeup. As grids continue to decarbonize, adding more wind, solar, and nuclear, heat pump emissions decrease further. Gas furnace emissions remain constant.
There’s another factor often overlooked: methane leakage. Approximately 3% of natural gas is lost to leaks from well to customer, and methane is 30-80 times more potent than CO₂ as a greenhouse gas depending on the time horizon. This leak impact increases total gas furnace emissions by roughly 40% (100-year calculation) to 115% (20-year calculation).
Beyond environmental impact, there’s a financial incentive: energy-efficient homes, including all-electric configurations, sell for up to 15% more in 2025 markets. As building codes increasingly favor electrification and gas hookup bans spread in certain municipalities, all-electric homes may have better resale value in coming years.

Homes where full electrification isn’t yet feasible due to electrical panel limitations or utility rates
Reducing winter peak demand on electric grids during the coldest daysResearch shows single-speed dual-fuel systems reduced CO₂ emissions in 9 states compared to furnace-only, while variable-speed dual-fuel reduced emissions in 15 states.
Your optimal heating system depends on three primary factors: geographic location, existing home infrastructure, and budget priorities.
| Factor | Heat Pump | Gas Furnace | Dual-Fuel |
| Northern Climate (Zones 5-6) | Cold climate models proven effective; requires HSPF2 8.8+ | Reliable for severe cold below -20°F; 95%+ AFUE recommended | Ideal for extreme variability and peak demand management |
| Southern/Mild Climate (Zones 1-3) | Most cost-effective; combined heating/cooling | 80% AFUE sufficient if choosing gas | Generally unnecessary |
| Existing Infrastructure | Works with ducts or ductless mini-splits; requires 240V circuit | Requires gas lines and ductwork | Requires both systems’ infrastructure |
| Budget: Upfront Cost Priority | Higher initial investment ($6K-$25K) | Lower upfront ($3.8K-$12K) | Highest (both systems) |
| Budget: Long-Term Savings Priority | Lower operating costs in most scenarios; 4-6 year payback | Depends on gas prices; volatile | Optimizes operational costs by climate |

The heat pump vs. gas furnace decision in 2026 isn’t binary. It’s contextual.
If you’re switching from a gas furnace to a heat pump system, these essential accessories can improve performance, protect your equipment, and ensure a reliable installation.
A strong wall mounting bracket helps secure your outdoor heat pump unit, improves airflow, and protects against ground moisture and debris.
A condensate pump removes excess moisture from your HVAC system, preventing leaks and protecting your home from water damage.
The 2026 landscape, with expired federal tax credits and impending 2028 efficiency standards, makes this decision more permanent than in previous years. The market has spoken: heat pumps are the future of home heating in most of North America. But ‘most’ isn’t ‘all.’ Run the numbers for your specific situation. Factor in your climate zone, utility rates, existing infrastructure, and long-term plans.
Whatever you choose, ensure it’s properly sized (via Manual J load calculation), installed by licensed professionals, and maintained according to manufacturer specifications. A correctly installed 95% AFUE furnace will outperform a poorly installed heat pump, and vice versa.
