Heat Pump
A Heat Pump is a versatile heating and cooling system that moves heat from one place to another. Unlike traditional heating systems that create heat, heat pumps transfer existing heat - similar to how a refrigerator works, but on a larger scale. They can both heat a building in winter (by pulling heat from outside) and cool it in summer (by removing heat from inside). This technology is becoming increasingly popular because it's energy-efficient and environmentally friendly. When reading resumes in the HVAC field, you'll often see this term mentioned as it's a key system that technicians work with.
