<h3>What are heat pumps?</h3>

It is characterized by being a thermal machine or a device based on thermodynamics that, through an absorption process, takes heat from one place and transfers it to another, that is, it extracts heat from a cold source to a hot one.

An air-to-air heat pump starts by sucking in outside air or recovers heat from outside and transfers it to a higher temperature level in the ambient air, raising the temperature of the room, being adjustable to adapt to the heating needs of  the conditioned space.

Therefore, we can conclude that according to the research, the correct option is remove. An air-to-air heat pump removes heat from the outside air and deposits it in the conditioned space..
