Why Does My AC Keep Starting Up and Shutting Back Down?

Your air conditioner does not run nonstop—or, at least, it shouldn’t. It runs in cycles, meaning that it starts up, cools your house until the desired temperature is met, and then cycles back down. When the temperature warms up again, the cycle repeats. It’s a simple, time-tested process, but it is not one that is always guaranteed to go without hiccups. If you notice that your air conditioner is starting up, but that it is shutting back down too quickly, only to start right back up again before long, you are dealing with what is known as short cycling. If you notice this issue on your property, contact us to schedule prompt AC repairs in Tucson, AZ.

What Causes Short Cycling, and Why Is it Such a Problem?

Short cycling may be caused by a few different issues. If your system has always malfunctioned in this manner, it’s possible that it is simply too large for your home, bringing temperatures up too quickly. We hope that this is not the case, though, as there is no real fix other than replacing the system. It may also be the result of a failing run capacitor, which helps to regulate current in the motor, or even a faulty thermostat. Those are certainly issues that repair services can resolve.

If you don’t think that short cycling sounds like that serious of a problem, think again. The constant starting and stopping can put seriously excessive wear and tear on your system, which increases the risk of operational problems developing. Not only that, but your system requires more power to get going than it does to run on a normal cycle. This means that short cycling can drive up your energy costs as well.
