What Is A Heat Pump And How Does It Work?
A heat pump is a versatile climate control system that heats and cools your home by transferring heat between indoors and outdoors. In winter, it draws warmth from the outside air (or ground, in geothermal models) and distributes it indoors. In summer, it reverses the operation to expel indoor heat. This technology delivers energy-efficient, year-round comfort.
