Is it true that heat pumps work in very cold climates?
Partly. Several peer-reviewed studies report ground- and air-source heat pumps operating through cold-climate heating seasons, and one reference text says cold climates should use air-source heat pumps. Other reference and peer-reviewed sources say heat pumps work less well or unreliably in very cold temperatures, so the evidence covers cold-climate operation only in part and points both ways.
