Edelman is committed to helping you understand the inner workings of your heating and cooling systems. One issue that many homeowners experience during the cooling season is something called short cycling. But what exactly is short cycling in an air conditioner, and why should it concern you?
In this blog, we’ll explain what short cycling is, why it can be a problem, and what causes it, so you know when to call the pros at Edelman for AC repair.
What Is Short Cycling?
Short cycling refers to when your air conditioner turns on and off too frequently, without completing a full cooling cycle. Instead of running long enough to properly cool your home, the system kicks on, runs for just a few minutes, and shuts off again—only to repeat the process over and over.
A normal AC cycle lasts anywhere from 15 to 20 minutes under moderate conditions. If your system is turning off in less than 10 minutes and restarting multiple times an hour, there’s likely a short cycling issue at play.
Why Is Short Cycling Bad?
While it may seem like your air conditioner is just working extra hard to cool your home, short cycling is actually a warning sign that something is wrong.
Here’s why short cycling is problematic:
- Increased Wear and Tear – Constant stopping and starting puts significant strain on the compressor, which is one of the most expensive components to replace.
- Reduced Efficiency – The system uses the most energy during startup. When it’s turning on frequently, your energy bills can skyrocket.
- Poor Comfort Levels – Because the system isn’t running long enough, your home may feel unevenly cooled or not cool enough at all.
- Humidity Problems – Part of your AC’s job is to dehumidify. If it can’t run long enough, humidity levels in your home may remain high, leading to discomfort or even mold issues.
Common Causes of Short Cycling
Short cycling doesn’t have a one-size-fits-all cause. It can be triggered by a number of issues, some more serious than others. Here are the most common culprits:
Dirty Air Filter
A clogged air filter restricts airflow, which can cause the system to overheat and shut down prematurely. Replacing or cleaning your air filter every 1–2 months can help prevent this issue.
Oversized Air Conditioner
If your AC is too powerful for your home, it may cool your space too quickly and shut off before completing a full cycle. While this might sound like a good thing, it actually reduces efficiency and shortens system life.
Low Refrigerant Levels
Leaking or low refrigerant reduces the cooling capacity of your AC. As a result, the system may struggle to maintain the set temperature, leading to frequent cycling.
Thermostat Issues
A malfunctioning or improperly placed thermostat (like near a sunny window) can cause inaccurate temperature readings, making the system cycle on and off too frequently.
Electrical or Control Board Problems
Faulty wiring, relays, or control boards can send incorrect signals to the AC, causing it to start and stop erratically.
