Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.
Coordinating the utility, meter and service equipment when the home needs more power from the street.
Adding a subpanel for a garage, ADU or new circuits when the main panel is out of space.

HAXX handles the permit, the inspection and the PG&E work order.
Large Piedmont homes built in the 1920s often still run on small or outdated services. Piedmont's code amendments also set how future electric loads are counted.
When AC or electric heat is added, Piedmont's amendments require the calculation to include an induction range, dryer and EV circuit, so the panel is ready for later projects.
Piedmont's rebate program now covers a main panel upgrade or a smart panel on its own, with higher amounts for income-qualified households. Confirm current terms.
Old homes may have original circuits, crowded panels or obsolete breakers. HAXX notes problems found during the upgrade.

“Recently, my dishwasher stopped working, and they discovered it was actually an outlet issue. Not only did they diagnose it quickly, but they also fixed the outlet—saving me from calling an electrician. Reliable, professional, and skilled at handling both appliances and electrical issues.”
“I purchased a couple of ceiling fans and was reluctant due to how old my house was with old wiring so I wanted someone professional and trustworthy. They have been both!”
“Prompt and professional - they helped run a new thermostat wire through a wall and crawl space.”

Not always. A load calculation, a smart panel or load management can avoid it in many homes. HAXX shows you the numbers.
Piedmont lists rebates for main panel upgrades and smart panels, applied for within four months of the permit. Funding is first-come, first-served.
Not always. A load calculation shows whether your current service can carry the new appliances, sometimes with load management. HAXX recommends an upgrade only when the numbers require it.
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
