As an expert in the field of HVAC systems, I can provide you with a detailed explanation on the functionality of heat pumps in cold weather conditions.
Heat pumps are designed to transfer heat from one location to another, regardless of the temperature outside. They can extract heat from the air even when the temperature is below freezing. This is because heat pumps operate based on the principle of refrigeration, which allows them to extract heat from the air or ground, even if it is colder than the inside of the building.
However, the efficiency of a heat pump can be affected by the external temperature. When the temperature drops below freezing, the heat pump has to work harder to extract heat from the air. The colder the air, the more energy the heat pump consumes to maintain the desired indoor temperature.
One of the critical aspects of heat pump operation in winter is the potential for ice formation on the outdoor components. When the temperature falls below freezing, ice may begin to form on the heat exchanger coils. This can impede the heat transfer process and reduce the heat pump's efficiency.
To counteract this, most heat pumps are equipped with a defrost cycle. The defrost cycle is a crucial safety feature that reverses the operation of the heat pump to melt any ice that has formed on the outdoor components. During this cycle, the heat pump will switch from its normal heating mode to a defrosting mode, where it uses the heat generated by the compressor to melt the ice.
This defrost cycle is essential for maintaining the heat pump's performance and preventing damage to the system. It ensures that the heat pump can continue to provide heat even in freezing conditions. However, it's important to note that the defrost cycle can also consume additional energy, which may affect the overall efficiency of the heat pump.
In summary, heat pumps can work below freezing, but their performance and efficiency can be impacted by the cold temperatures. The defrost cycle is a vital feature that helps to maintain the heat pump's operation and prevent damage due to ice formation. Proper maintenance and preparation for winter conditions are essential to ensure that your heat pump continues to provide reliable heating.

Your heat pump can always pull heat out of the air. ... But, it's crucial for heat pump operation in winter. Ice may begin to form on your outdoor components when the temperature drops below freezing. So, your heat pump will reverse operation to defrost those components.
