Northeast Energy Efficiency Partnerships - a non-profit that maintains the Cold Climate Air Source Heat Pump specification list.

Coefficient of Performance at 5°F outdoor temperature. Higher values mean better cold weather efficiency - a COP of 2.0 means 200% efficiency.

Seasonal Energy Efficiency Ratio (updated test procedure). Measures cooling efficiency - higher SEER2 means lower cooling costs.

What makes a heat pump "cold climate"?

Models must meet NEEP specifications including rated heating capacity at 5°F and COP values that demonstrate efficient operation in freezing temperatures.
