When an air conditioner short cycles, it is usually an indication that something is not right with the air conditioner.
The thermostat of an air conditioner or an HVAC system usually switches on and off when the air conditioner reaches the set temperature. Once the temperature in a room begins to increase the air conditioner switches on again. It brings the room back to the set temperature.
However, there are times, when an air conditioner shuts on and off in repeated cycles within short periods of time and in rapid succession. This is known as short cycling.
When an air conditioner short cycles, it is often an indication that something is not right with the air conditioner. A short cycling air conditioner system harms the energy efficiency of your air conditioner, as well as affects the overall health of your air conditioner.
The following are a few reasons your air conditioner may be short cycling:
- Oversized air conditioner – The most common issue that leads to short cycling is installing an air conditioner that is too big, and more powerful than the area it is designed to cool. Many air conditioner owners think that the bigger the air conditioner, the faster it will cool the room. While this is often true, they tend to overlook the fact that when oversized air conditioner’s cool down smaller rooms, they do not completely dehumidify the air, resulting in a clammy, damp room, with higher fluctuations in temperatures. These fluctuations result in wearing the motor and the other components of the air conditioner faster.
- Ice on evaporator coils – Ice developing on the evaporator coils of the air conditioner can result in short cycling. When ice develops on the evaporator coils causing short cycling, it is most often a refrigerant issue or an airflow problem.
- Dirty air filter – A dirty air filter or a clogged air filter could cause a reduction in air flow or insufficient air flow, resulting in an AC turning on and off or short cycling. The air conditioner could face increased wear and tear due to the rapid fluctuations in air temperature, making it work harder than needed.
- Leak or loss of refrigerant – The refrigerant keeps the air conditioner cool. If there is a leak in the refrigerant holder or loss of refrigerant, the heating parts of the AC can over heat causing short cycling.
- Thermostat issues – Issues with a malfunctioning thermostat can also cause short cycling problems.
It is essential for HVAC owners to read and understand the user’s manual before trying and self-troubleshooting the issue at hand. A number of complications that could lead to short cycling are often well beyond the means of a homeowner trying to troubleshoot the issue on their own.
