The belief that heat pumps are ineffective in cold climates is outdated. While older models can struggle at low temperatures, modern cold-climate heat pumps are specifically designed to perform efficiently in colder regions. These advanced systems use innovative technologies to extract heat from outdoor air, even in freezing conditions, making them a viable heating option during harsh winters.According to the U.S. Department of Energy (DOE), modern cold-climate heat pumps can operate efficiently in temperatures as low as 5°F, with some manufacturers advertising reliable operation as low as -5°F.(1)(3) These advancements make heat pumps suitable for a wide range of geographical locations, including colder climates where traditional systems like gas furnaces have typically been preferred.(1)
