A heat pump condenser is the outdoor unit of a heat pump HVAC system. It plays a major role in both home heating and cooling. In warm weather, the condenser helps cool your home by removing heat from the inside. In cold weather, it works in reverse—pulling in heat from the outside air to warm your home, even when it’s chilly outside.

If you have a heat pump system, this unit is what makes it possible to keep your home comfortable year-round with energy-efficient climate control.
