A heat pump installation can range from approximately $4,500 to $25,000, with the average cost for a typical system being around $6,000 to $15,000, according to various sources.
Of course the final price depends on the equipment manufacturer, capacity, complexity of installation, home size and location.

A well-maintained heat pump typically lasts 10 to 15 years, but with advances in technology and proper care, some units, especially ductless mini-splits or ground-source models, can last 20 to 25 years or more.
Of course the lifespan depends on the equipment manufacturer, installation, and regular preventive maintenance.

Heat pumps should be serviced by a professional at least once a year, with a recommendation for two check-ups per year—once in the spring and once in the fall. Professional maintenance involves cleaning coils, checking electrical components, lubricating motors, inspecting refrigerant levels, and ensuring proper airflow, which helps prevent costly breakdowns and extends the unit’s lifespan.
