Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Smart panels and circuit-sharing devices that can avoid a service upgrade in some homes.
HAXX handles the permit, the inspection and the PG&E work order.
Homes from Pinole's 1960s and 1970s growth were wired for gas heat and fewer appliances. Electrifying often means more capacity, or smarter use of what is there.
HAXX calculates the existing load to see whether the current service can carry new equipment before recommending an upgrade.
Pinole lists an instant permit option for residential service panel upgrades and replacements, or an eTRAKiT Residential Electrical permit.
Service size changes need PG&E work at the meter. HAXX coordinates the disconnect and reconnect.

“I told him that the lights in my living room had been flickering for a while and asked if he could take a quick look. Instead of brushing it off, he immediately went to the main panel, asked a few questions, and then checked my subpanel in the garage.”

A load calculation compares your existing and planned loads against the service rating. HAXX does this during the estimate.
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.
