Cold-Climate Heat Pump (ccASHP)
A heat pump specifically designed to maintain high heating capacity at very low outdoor temperatures (typically rated to -13°F/-25°C or lower).
Why It Matters
Cold-climate heat pumps have eliminated the old objection that heat pumps don't work in winter. Brands like Mitsubishi (Hyper-Heating) and Daikin (Aurora) maintain full capacity to 5°F.

Heat Pump
An efficient HVAC system that transfers heat rather than generating it, providing both heating and cooling. Air-source heat pumps are most common; ground-source (geothermal) are most efficient.
COP (Coefficient of Performance)
The ratio of heating or cooling output to electrical energy input for a heat pump. A COP of 3.0 means the system produces 3 kWh of heat for every 1 kWh of electricity consumed.
