It should come as no surprise that one of the most important elements that affect the lifespan of an A/C unit, like any appliance, is how often it is used. An A/C unit in a region where frequent use is required on average can last 10 to 15 years, while one that is used less frequently may continue operating for 20 or even 25 years (all other variables held constant).
In order to extend the life of your unit, consider turning the thermostat up a couple of degrees so there is less strain put on the unit. In most cases, this will not result in much impact on your comfort level, but it can have a significant impact on the performance of your system over time.
