Heat Pump Guide
Discover why heat pumps are the most efficient way to heat and cool your home, with significant rebates available in 2026.
Heat Pump Types
Air Source Heat Pump
Most common type. Extracts heat from outdoor air, even in cold weather. Modern cold-climate models work down to -15°F.
15-22 SEER2 / 8-10 HSPF2
15 years
Best in moderate climates (30°F+)
Pros
- Affordable
- Proven technology
- Heats and cools
- Works with ducts
Cons
- Efficiency drops in extreme cold
- May need backup heat
- Outdoor unit required
Mini-Split Heat Pump
Ductless system with individual indoor units. Excellent for zoned heating/cooling without ductwork.
18-30+ SEER2 / 10-14 HSPF2
20 years
All climates with cold-climate models
Pros
- No ducts needed
- Zone control
- Very efficient
- Quiet operation
Cons
- Visible indoor units
- Higher cost per zone
- Multiple units for whole home
Geothermal Heat Pump
Uses stable underground temperature for maximum efficiency. Ground loop buried in yard or drilled vertically.
45-60 EER (400-600%)
25+ years (50 for ground loop)
All climates
Pros
- Highest efficiency
- Works in all climates
- Longest lifespan
- 30% federal tax credit
Cons
- Highest upfront cost
- Requires land for loop
- Complex installation
Dual Fuel Heat Pump
Heat pump paired with gas furnace backup. Uses heat pump when efficient, switches to gas in extreme cold.
Variable
15-20 years
Cold climates
Pros
- Best for cold climates
- Optimal efficiency
- Reliable backup
Cons
- Higher upfront cost
- More complex
- Requires gas line

Cold Climate Performance
Modern cold-climate heat pumps maintain efficiency even in freezing temperatures. Here's typical performance:
Maximum efficiency, 4x more efficient than electric heat
Excellent efficiency, standard operation
Good efficiency, standard heat pump range
Cold-climate models still very efficient
Cold-climate models maintain good output
Cold-climate models still more efficient than electric
Best cold-climate models can still operate
Frequently Asked Questions
Heat pumps move heat rather than generate it. In winter, they extract heat from outdoor air (even in cold weather) and move it inside. In summer, they reverse to remove heat from your home. This makes them 2-4x more efficient than systems that generate heat directly. Modern refrigerants allow heat extraction even below 0°F.
Yes, modern cold-climate heat pumps work efficiently down to -15°F or colder. Models like Mitsubishi Hyper-Heating and Bosch Cold Climate maintain 100% capacity at 5°F. In extreme cold, efficiency drops but remains better than electric resistance heat. Dual-fuel systems pair heat pumps with gas backup for the coldest days.
Heat pump savings depend on what you're replacing and your climate. Replacing electric resistance heat saves 30-50% on heating bills. Replacing oil heat often saves 40-60%. Replacing gas can save money in moderate climates but may cost more in very cold areas with cheap gas. Factor in cooling savings too.
Heat pumps are more efficient and provide both heating and cooling. Furnaces heat faster and work reliably in any temperature. In moderate climates (above 30°F most of winter), heat pumps are usually the better choice. In very cold climates, consider a cold-climate heat pump or dual-fuel system. Gas furnaces remain cost-effective where natural gas is cheap.
