Heat pumps in cold weather
Canonical HVACentric knowledge for residential questions on this topic.
DIRECT ANSWER
Modern heat pumps can operate in cold weather, but capacity and efficiency change as outdoor temperature falls. A good proposal considers the building load, the selected equipment’s published low-temperature performance, electrical service, controls, ducts or indoor units, and the backup-heat strategy. Climate suitability cannot be decided from the words “heat pump” alone.
