Unfortunately, there is not a one-size-fits-all answer to this question. Instead, the lifespan of an air conditioning unit can vary greatly depending on the type, brand, amount of use and other factors.
With this in mind, we will look at these various factors and provide some average numbers depending on the type of AC unit.
This will allow you to estimate how long the aircon unit you currently own or are considering buying will last.
