Think of a panel tune-up like an oil change and multi-point inspection for your car, but for your home’s electrical heart. Over time, the everyday flow of electricity causes minor vibrations, and the natural heating and cooling of copper and aluminum wires can cause connections to loosen.During a tune-up, a licensed electrician removes the panel cover to inspect internal components, check for hidden hot spots using thermal imaging, clean out dust or corrosion, verify your grounding system, and tighten every terminal screw to exact manufacturer specifications.

A standard residential panel upgrade typically takes between 4 and 8 hours to complete. As for the power, yes, your power will need to be completely shut off for a significant portion of the day.

Insurance companies view certain older electrical panels as severe fire hazards. Brands like Federal Pacific Electric (FPE), Zinsco, and old Challenger panels have documented manufacturing defects where the breakers fail to trip during an overload, melting the wires and starting wall fires. If your home has one of these legacy panels, your insurance provider may threaten to drop your coverage entirely or significantly raise your premiums until you provide proof of a professional replacement by a licensed electrician.

For a standard residential home, upgrading from an old panel to a modern 200-amp system generally costs between $2,500 and $5,500.

We recommend having a professional panel tune-up and safety inspection performed once every 3 to 5 years for standard homes. However, you should schedule one sooner if your home is more than 25 years old, if you have recently added high-draw appliances (like a hot tub or EV charger), or if you notice your breakers humming or your lights flickering.

Yes, indirectly! When internal connections are loose or corroded, they create electrical resistance. This resistance forces your electrical system to work harder and draw more current to power your home, generating wasted heat inside your panel box. By cleaning the bus bars and tightening connections, electricity flows smoothly and efficiently. Furthermore, identifying a failing breaker early prevents it from damaging expensive connected appliances like your HVAC compressor or refrigerator.
