Cold-Climate Heat Pump Technology

How Cold-Climate Heat Pumps Work

Traditional Heat Pumps:

• Performance declines below 40°F
• Need backup heat below 30°F
• Efficiency drops significantly in cold

Cold-Climate Heat Pumps:

• Advanced compressor technology
• Variable-speed compressors
• Enhanced refrigerant systems
• Performance maintained down to -15°F
• May still need backup heat in extreme cold (<-15°F)

Key Technologies

Variable-Speed Compressors:
