Heat pumps typically last between 10 to 15 years, though this can vary depending on the type of heat pump, how well it's maintained, and the climate in which it operates. In Florida's mild climate, with proper maintenance, a heat pump can sometimes last even longer, potentially up to 20 years. Regular servicing, which includes cleaning the coils, checking refrigerant levels, and ensuring the system is operating efficiently, can significantly extend the lifespan of your heat pump.
