A heat pump is a part of a home heating and cooling system that is installed outside the house. It is an energy-efficient alternative to furnaces and air conditioners for all climates. Heat pumps use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house, while during the cooling season, heat pumps move heat from your house into the outdoors. Heat pumps transfer heat rather than generate heat, which makes them more efficient than furnaces and baseboard heaters. There are three main types of heat pumps connected by ducts: air-to-air, water source, and geothermal. The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air. Ground-source heat pumps, also called geothermal heat pumps, transfer heat between the air inside your home and the ground outside. Heat pumps are powered by electricity and transfer heat using refrigerant to provide comfort all year round.

In summary, a heat pump is a versatile, efficient cooling and heating system that transfers heat from one place to another using electricity and refrigerant. It can cool your home in the summer and heat it in the winter, making it a great alternative to furnaces and air conditioners.
