We just had an electrician update our electrical in our old house. Went from knob and tube to conduit throughout the entire house and updated our panel from 100 to 200 amps. When our A/C or dishwasher kick on, our lights still briefly flicker. It was a problem before but we assumed once we got the additional amps, it wouldn't happen anymore. Is that still common despite our upgrades? If not, what is the problem? just want to have some insight into the issue before we address with the electrician.
Thanks in advance for any feedback!
