Here’s What You Need to Know About Short Cycling
If you’ve noticed your central air conditioning system cycling on and off more frequently than it should, you’re likely experiencing what is known as “short cycling.” This common issue can not only be annoying but also increase your energy bills and put unnecessary strain on your air conditioning system, potentially shortening its lifespan.
At Central Heating Cooling Plumbing Electrical in Kalispell, we see this issue a lot, and have compiled a comprehensive guide to help you understand the possible causes of short cycling and how to address them, including when it’s time to call in the professionals.
Common Causes of Air Conditioner Short Cycling
Dirty Air Filters
A clogged air filter restricts airflow, which in turn can cause the air conditioner to overheat and shut off. Once it cools down it will run again until the temperature gets to hot again. Check and replace your air filters regularly.
Thermostat Issues
If your thermostat is improperly placed (near windows, doors, or in direct sunlight), it may misread the actual room temperature, leading to frequent cycling.
Low Refrigerant Levels
Refrigerant leaks can cause the system to shut down due to low pressure. This issue requires professional attention.
Oversized AC Unit
An air conditioner must be sized properly for the home. An AC that is too large for your home can cool it too quickly, causing it to turn on and off frequently.
Electrical Problems
Wiring issues within the AC unit or circuitry problems can lead to intermittent operation.
DIY Fixes to Try
Replace the Air Filter
Start with the simplest solution by checking and replacing your air filter if it’s dirty.
Reposition Your Thermostat
Ensure your thermostat is in a location that accurately represents your home’s overall temperature, typically this will be in an interior room or hallway.
Inspect the Condenser Unit
Clear any debris around your outdoor condenser unit to ensure proper airflow.
