A residential heat pump typically has an average operational lifespan of 10 to 15 years, though well-maintained units in moderate climates can occasionally last up to 18 to 20 years. Because heat pumps operate continuously year-round for both heating and cooling cycles, they accumulate more runtime hours than standalone furnaces or air conditioners, leading to accelerated mechanical wear on compressors and reversing valves. Regular annual professional maintenance is vital to maximizing their longevity.
