Of course, it all depends on the amount of service the device receives and how often the equipment was used.
It’s safe to say that everything that is tangible has an expiration date, even our bodies will expire at some point. And like our bodies most tangible items will last longer the better we take care of them. Duke visits his doctors so that he can identify any unforeseen issues that could be lurking in his body. And he also visits his doctors to make sure that all his organs are healthy and functioning in the most optimal way. If an issue is discovered, Duke immediately takes the necessary steps to rectify the concern in the best way possible. If he provides the same attention to other tangible items around him, the lifespan can be extended. For example, the Heating, Ventilation & A/C equipment is perhaps one of the most essential devices in Duke’s home so, it makes sense to maintain the equipment so that it could perform in the most efficient way. Most Heating, Ventilation & A/C units have an average lifespan between 15 and 20 years. However, in some cases, Heating, Ventilation & A/C equipment could last up to 25 years. Of course, it all depends on the amount of service the device receives and how often the equipment was used. While the equipment might lose efficiency, it is possible to extend the life of an Heating, Ventilation & A/C equipment with respected service. However, it is commanded that once an Heating, Ventilation & A/C plan is near or at its expiration date that it is updated for a more efficient unit. It would be nice if people could update their bodies for a more efficient one when they expire as well.
