One of the most common reasons customers call our HVAC technicians for air conditioning repair in Chicago, IL is when they have an AC that’s turning on and off almost constantly over a short time. This is known as short-cycling, and there are many different potential causes:
- A clogged air filter
- Undercharge of refrigerant due to leaks
- Leaks in the ventilation system
- AC is too powerful for the space
- Dirty or iced-up refrigerant coils
Short-cycling is both a symptom of a problem and a problem on its own since it significantly increases the workload on the air conditioner. Parts wear down faster, cooling bills rise, and the system will end up needing an early replacement.
But how long should an air conditioner’s cooling cycle last? Understanding this is important so you can know when you’ve got an AC that’s short-cycling.
