Why Does My AC Turn Off By Itself?

Air conditioner maintenance being performed

Is your air conditioning behaving strangely, turning on and off frequently without maintaining a consistent cooling cycle? This issue — known as “short-cycling” — isn’t just frustrating; it may indicate an underlying problem with your cooling system that requires expert attention.

What is Short-Cycling?

Short-cycling is when your air conditioner turns on, runs for a short period, and then shuts off prematurely before completing a full cooling cycle.

Instead of maintaining a steady temperature, the system repeats this rapid on-off cycle, compromising comfort and putting unnecessary strain on the AC unit.

Possible Causes of Short-Cycling

There are several reasons your air conditioner may start short-cycling. These are some of the most common possible causes:

  • Improper sizing: If your AC is too large or too small for your space, it can lead to short-cycling. An oversized unit cools the area quickly, causing it to reach the set temperature too fast and shut off abruptly. An undersized unit struggles to cool the space efficiently, leading to frequent cycling as it tries to maintain the desired temperature.
  • Clogged filter: A dirty or clogged air filter restricts airflow, causing the AC to overheat. To protect itself, the system shuts off automatically, resulting in short-cycling. Regularly cleaning or replacing the air filter at proper intervals is crucial to prevent this.
  • Thermostat placement: Incorrect thermostat placement can lead to inaccurate temperature readings. If the thermostat is exposed to direct sunlight, near a heat source, or in a drafty area, it may sense the wrong temperature, causing the AC to cycle on and off incorrectly.
  • Refrigerant leaks: Insufficient levels of refrigerant due to leakage can cause the evaporator coil to freeze up. This triggers the system’s safety mechanisms, resulting in short-cycling to prevent further damage to the unit.
  • Faulty components: Various faulty AC components, such as a malfunctioning compressor, faulty fan motor, or defective thermostat, can disrupt the proper functioning of your AC system, leading to short-cycling.
