Heat Pumps Hold Up In Cold

Cold-climate heat pumps are increasingly presented as a viable heating option for homes and other buildings in harsh North American climates, including during subfreezing and isolated extreme-cold periods.

Their performance depends heavily on equipment selection, load sizing, insulation, controls, distribution systems, and professional commissioning, while supplemental or dual-fuel heating may still be needed at the lowest temperatures. Incentives, local electricity prices, and installation quality remain central to whether the technology delivers practical cost and emissions benefits.
