The short answer to this question is that the expected lifespan of any given air conditioner is about 10-15 years, with most AC manufacturer warranties covering repairs and replacement for 10 years. There are a lot of factors that impact this lifespan though. For instance, the type of air conditioner you have matters. The most common types of air conditioners in Georgia homes are the central AC system, the ductless mini-split, and the heat pump system. Ductless systems tend to last a little longer as a whole system because you can replace each air handler as they fail without replacing the whole entire system. Standard heat pumps and central AC systems though stick pretty firmly to that average lifespan.
