The answer to 'how long does heat pump last' is that a properly maintained heat pump can last 15-20 years on average. Heat pumps are complex systems that include an outdoor unit, indoor air handler, and refrigerant lines. With regular professional maintenance and proper care, a heat pump can provide reliable heating and cooling for a long time. However, factors like climate, usage, and installation quality can impact the lifespan.
Heat pumps are generally more durable than traditional HVAC systems like furnaces and air conditioners. They have fewer moving parts and don't experience as much wear and tear. But over time, components like the compressor, fan motors, and refrigerant can degrade, reducing efficiency and eventually requiring replacement. Staying on top of annual tune-ups and addressing any issues promptly can maximize the life of a heat pump.
