As we arrived today, Robert said he had a funny sound coming out of his electrical panel. After we removed the panel cover, we heard the sound on multiple occasions. We finally traced it down to the two AFCI breakers in the bottom right corner of the panel. I tried to manually trip both of them. One of them would trip after a few seconds the other one would not trip at all. When it did, it was making the sound that was pretty close to what we heard to begin with. Both breakers are defective and need to be replaced. We removed both our fault breakers and replaced them with new dual function Siemens breakers. Restored power and both breakers worked properly and tripped properly. Also talked to Robert about installing a whole panel surge protector. I’m leaving an attached quote for that as well. It was great meeting you today, Robert! If you have any questions about the estimate or need anything else, please feel free to give me a call anytime. Thank you, Brandon
