How long will an old air conditioning unit keep running before it needs to be replaced?

Some have certainly seen better days, but I’ve seen much older units still chugging along. Age alone isn’t the death sentence for these machines. While newer models offer unbeatable efficiency, quieter operation, and all the bells and whistles, I’ve got plenty of 20-year-old units still keeping their owners cool.

The key is the current performance. If it’s still providing reliable comfort, then there’s no immediate need to replace it. It all boils down to your priorities.
