Some common factors that affect the life of an air energy heat pump:
Quality & Build Quality:The quality and manufacturing quality of a heat pump directly affects its lifespan. Better quality equipment usually uses high-quality materials and advanced manufacturing processes to have a longer lifespan.
Device Installation:Proper installation is critical to the operation and longevity of a heat pump. A good installation includes a suitable location selection, proper piping layout, solid facility installation, etc.
Maintenance & Care:Regular maintenance and upkeep can extend the life of your heat pump. This includes cleaning filters, checking refrigerant levels, checking electrical connections, cleaning condensers and evaporators, etc.
Environmental factors:Environmental factors can affect the operation and life of heat pumps. For example, high temperature environments, humid climates, corrosive gases, etc., can adversely affect the operation of heat pumps.
Conditions of use:The conditions under which a heat pump is used can also affect its lifespan. For example, too frequent start-stops, too much load, too high or too low a temperature setting can have a negative impact on the operation and service life of a heat pump.
Running time:The service life of an air energy heat pump is usually related to its operating time. Long operating times can lead to aging and wear of components, which can affect the life of the heat pump.
Frequent maintenance:Frequent repairs and troubleshooting can have a negative impact on the life of a heat pump. Therefore, the importance of regular maintenance and upkeep cannot be overlooked. 
In summary, factors such as the use environment, maintenance, design and installation quality, use method, quality brand, and selection of components and components of air energy heat pumps will have an impact on their lifespan.
