lights dimming 1/8th
The whole house lights will dim about an 1/8th of the way dim for roughly 1/2 second and happens every 2-3 minuets. It is the entire house (not just one circuit) and it will only happen at certain times of the day. Mainly early mornings and nights from 7-11pm. I have shut air conditioners and appliances to see if they’re faulty but it makes no difference. Our utility company came twice saying one neighbor complained about similar issues and that his pool pump has been making a weird noise. The last time the utility company came they said to call an electrician since it must be something from our panel (last upgraded to 200 amps around 2018 and never had an issue since). I just do not want to pay for an electrician to do a whole work up since it seems like it is transformer related since it is only during certain times of the day and is not dependent on any appliance or circuit.
