If your air conditioner is starting and stopping frequently enough that you’re asking yourself this question, then the answer is probably no. Now, you have to keep in mind the fact that your air conditioner should not be running constantly, either. ACs are designed to run in cycles, meaning that they should adjust temperatures, shut down, then start back up in relatively even and regular intervals. An AC that is running constantly is no better off than one that starts and stops very frequently.
When it comes to your air conditioning in O’Fallon, MO, you have to keep in mind that “good enough” is never really good enough when it comes to its performance! Truth be told, short cycling may not be indicative of a very serious air conditioning problem. At least, it may not start out that way. However, short cycling may also be caused by a very serious issue, and itself will damage the system if left alone long enough.
