Air conditioners are complex pieces of machinery, so when anything in them breaks, it requires detective work to locate the cause. This is one of the reasons we recommend you turn to professionals only when you have an air conditioning system that isn’t working. Unless the problem is basic–like a tripped circuit breaker–it takes skilled technicians to find out what the specific malfunction is so it can be fixed.
Today we’re looking at a common source of a “no cool” air conditioner: a broken fan. There are two fans in an air conditioning system handling different jobs. If either fails, you won’t have indoor cooling.
