Load calculation
A written load calculation of existing and planned appliances, so you know whether you need more capacity at all.
Panel out of space or too small for a heat pump, EV charger or ADU? HAXX upgrades panels in Oakley with a load calculation, city permit and PG&E coordination.
Serving Summer Lake, Cypress Grove, Vintage Parkway, the Laurel Road corridor, Downtown Oakley and the Delta waterfront and the rest of Oakley. Share your address to confirm availability.

Most panel projects start with a heat pump, EV charger, induction range or remodel. HAXX begins with your real electrical load and only upgrades what the numbers require.

Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Oakley's newer tract homes often have more capacity than the older homes near Main Street, but adding an EV charger, heat pump and ADU together can still exceed it.
HAXX calculates actual demand under the California Electrical Code before recommending an upgrade. Many homes do not need one.
Homes near Downtown can have aging panels with no spare spaces. Replacement restores capacity and safe breakers.
HAXX files with the City of Oakley, schedules the PG&E disconnect and reconnect, and meets the inspector.

“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.”
“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.”

Typically one working day, depending on PG&E's schedule for the disconnect and reconnect.
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.
