Heat pumps give year-round comfort to the users and help in lowering energy costs. It is a device that transfers heat energy from one source to another or a thermal reservoir. Heat pumps come with four main components: a condenser, compressor, an expansion valve, and an evaporator. While freezers and air conditioners are typical examples of heat pumps, the term is quite general. Many heating, ventilation, and air conditioning devices used this term for space cooling or heating mode. These devices offer energy-efficient alternatives to air conditioners and furnaces for the climates with moderate cooling and heating needs. They come in three different types: a water source, air-to-air and geothermal, and collect heat from water and air to concentrate it for inside use. Heat pumps make the warm space warmer and cold space cooler using electricity to move heat from a warm place to a cool place.
