This is a question often we hear from homeowners. They want their air conditioning systems to last as long as possible, but they also know that “possible” doesn’t include “forever.” At some point, the air conditioner will age past the point where it’s pragmatic to continue fixing it. It also develops a higher risk of permanently breaking down on a hot day—and nobody wants that to happen!
However, we can’t give you a definite answer about the age at which a central air conditioning system needs to be replaced. It differs depending on the system, how much use it has seen, and if it receives regular maintenance.
