A well-maintained heat pump typically lasts between 10 to 15 years, with some models lasting even longer. Regular maintenance, such as cleaning the air filters, checking refrigerant levels, and ensuring the system is running efficiently, can extend the lifespan of your heat pump. The outdoor unit, which is exposed to the elements, may require additional attention, such as cleaning coils and ensuring the fan is in good working order.
Replacing worn-out parts promptly can also help extend the life of the system. In general, heat pumps have a longer lifespan than many traditional heating systems, making them a reliable investment.
