However, the ground loop is warrantied for fifty years plus can be relied upon to last twice that long. The actual heat pump is located inside the home plus protected from the elements. With proper service, the unit should supply dependable performance for twenty-plus years. With few moving parts, there are fewer service requirements plus little that can go wrong.
