Hello, my name is XXXXX XXXXX I'm here to answer any of your electrical questions.
Does this happen at any given time? Or when a event is happening? Like when the air conditioner kicks on?
What kind of lights do you have as far as the bulbs go? Fluorescent, led's or incandescent?
CFL's are very sensitive and sometimes flicker any time there is a fluctuation in voltage. The best advice I can give you right now is to call the power company, let them know what is going on, and they will check their side of things. When the CFL is not the problem and there is flickering going on the cause is usually related to a loose neutral on the power companies side of things.
Another thing you can do is make sure that all of your connections in your panel are nice and tight Make sure to turn off the main breaker first. Then remove the outer panel. After that you will see all the connections where the wires attach to. The breakers, and the ground and neutral bar, or bars. Tighten all of them.
THank you very much. If you have further questions, just let me know. Please rate, and thank you for your time.
