How does a heat pump work in the winter?

A heat pump is an efficient HVAC system that works by transferring heat from one area to another. In the winter, a heat pump extracts heat from the outside air and transfers it into the home. This process is known as air-source heat pumping. The heat pump uses a refrigerant to absorb the heat from the outside air and then compresses it to a higher temperature. The heat is then released into the home, providing warmth and comfort. Heat pumps are also capable of reversing the process and providing cooling in the summer.
