When a heat pump goes into defrost mode, it temporarily reverses its operation to warm the outdoor coil, melting any accumulated frost or ice. This process involves the heat pump drawing heat from the indoor air and transferring it to the outdoor unit, preventing ice build-up that can hinder efficiency. The defrost cycle typically lasts only a short time, after which the system resumes normal heating operation. The unit may also briefly stop blowing warm air indoors during this cycle.
