You know when your air conditioner won’t come on that something is wrong. Maybe the fan isn’t activating, so there’s no air coming from the vents. Or the compressor isn’t responding, so the air from the vents is at room temperature—and that’s no help on a hot summer day. You’ll know you need to call for repairs ASAP.
There’s the reverse situation, and it’s just as bad—the air conditioner that won’t stop running. You may not at first notice this. No matter how hot it is, the AC isn’t supposed to have the compressor or fan run continuously. It’s supposed to operate in cycles. A “runaway” air conditioner is a problem, and we’re going to look into it a bit deeper.
