Which outcome arises when a heat pump's outdoor coil ices over during winter operation?

💡 Explanation

When the outdoor coil of a heat pump ices over, thermal resistance increases because ice insulates the coil and reduces heat transfer from the environment, dropping heating capacity. Therefore reduced heating capacity and efficiency arises, not a longer motor lifespan, increased subcooling, or decreased temperature stratification which require opposite changes to cooling system performance.
