Does your air conditioner keep turning on and off like it’s got a mind of its own? You’re not dealing with a haunted HVAC system, but something called short cycling, and unfortunately, it’s more serious than it sounds.

What Is Short Cycling, Exactly?

Short cycling happens when your AC turns on, runs for a brief period, and then shuts off before completing a full cooling cycle. Then it starts again. And again. This rapid on-and-off pattern isn’t just annoying, it can lead to major problems if left unchecked.

Why Is Short Cycling Bad News?

Short cycling puts unnecessary stress on your AC system. Think of it like constantly stopping and starting your car in traffic. Over time, the wear and tear build up. Here’s what can happen:

  • Increased wear on the compressor – One of the most expensive components in your system, the compressor isn’t built to start and stop constantly.
  • Higher energy bills – Starting up uses more electricity than running consistently. The more it starts, the more it costs.
  • Uneven cooling – Because the system never completes a full cycle, your home may feel too warm in some areas and too cold in others.
  • More frequent repairs –  Components that are constantly working harder than necessary tend to fail sooner.

What Causes Short Cycling?

Now that we know what short cycling is, let’s look at the usual suspects behind it:

  • Clogged air filters – A dirty filter restricts airflow, causing the system to overheat and shut off early.
  • Refrigerant issues – Low refrigerant levels or a leak can make it difficult for your AC to cool effectively, leading to short cycles.
  • Oversized AC units – Bigger isn’t always better. A unit that cools your space too quickly will shut off before properly dehumidifying.
  • Faulty thermostats – If the thermostat is misreading your home’s temperature, it might be telling the AC to turn off prematurely.
  • Leaky ducts or frozen coils – These airflow issues can trigger your system to shut down unexpectedly.

When Should You Call A Professional?

If your AC is short-cycling every 5 to 10 minutes, it’s time to call in an expert. You should also reach out if you notice:

  • Rising energy bills
  • Inconsistent temperatures
  • Strange noises or smells coming from the unit
