Finding efficient heating for your home is critical in areas where the temperatures drop. Heat pumps have become popular because they can heat and cool your house using less energy. Let’s look at the best heat pumps for cold places, checking out what they can do and how well they work when it is freezing outside.
Key Takeaways
- Cold climate heat pumps are designed to work efficiently in temperatures as low as -13°F (-25°C), using advanced technology to get heat from cold air.
- The best 5 heat pumps for cold climates include models from Mitsubishi, Fujitsu, Carrier, Lennox, and Daikin, each offering unique features and high efficiency ratings.
- When choosing a cold climate heat pump, consider factors like heating capacity, minimum operating temperature, energy efficiency ratings, and proper installation for best performance.
How Does Heat Pump Technology Work in Cold Climates?
Heat pumps move heat from outside air into your home, even in cold weather. Regular heat pumps have trouble when it is extremely cold, usually below 32°F (0°C). That’s where heat pumps made for cold places come in.
Cold climate heat pumps are specifically designed to work efficiently in low temperatures, often down to -13°F (-25°C) or lower. They use advanced compressor technology and refrigerants that can extract heat from cold air more effectively than standard models.
Key Features of Cold Climate Heat Pumps:
- Variable-speed compressors
- Improved vapor injection
- Larger coils for increased heat exchange
- Optimized defrost cycles
- Improved refrigerants
These features let cold climate heat pumps maintain high efficiency and heating capacity even when outdoor temperatures drop significantly.
Maximize your home’s heating efficiency by combining solar air heating with solar radiant heating to get consistent warmth and energy savings.

- Coefficient of Performance (COP). Look for a high COP at low temperatures, indicating better efficiency in cold weather.
- Minimum Operating Temperature. Pick a heat pump that can work well at the coldest temperatures in your area.
- Defrost Mechanism. An efficient defrost system is crucial for maintaining performance in freezing conditions.
- Backup Heating. Consider a system with built-in electric resistance heating or one that can work with your current heating system for extremely cold days.
- Energy Efficiency Ratings. Higher HSPF and SEER ratings mean it uses energy better overall.
- Installation and Maintenance. Factor in the costs and requirements for professional installation and regular maintenance.
Energy Savings and Environmental Benefits
Cold climate heat pumps can save a lot of energy compared to traditional heating systems like furnaces or boilers. By moving heat instead of making it by burning fuel, they can be 300% efficient or more. This means they can make 3 units of heat for every 1 unit of electricity they use.
This high efficiency means lower energy bills and reduced carbon emissions. According to the U.S. Department of Energy, switching to a heat pump can save homeowners hundreds of dollars annually on heating costs, with even greater savings in colder regions.
Comparison of Annual Heating Costs
| Heating System | Annual Cost (Cold Climate) |
| Heat Pump | $500 – $1,000 |
| Natural Gas | $800 – $1,500 |
| Oil Furnace | $1,200 – $2,000 |
| Electric Resistance | $1,500 – $2,500 |
Note: Actual costs may vary based on local energy prices, home size, and insulation levels.
Installation Considerations
Proper installation is crucial for the performance and longevity of cold climate heat pumps. Here are some key considerations:
- Sizing. An accurately sized system ensures optimal efficiency and comfort.
- Placement. The outdoor unit should be installed in a location that allows for proper airflow and is protected from extreme wind and snow buildup.
