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Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Much of Daly City was built in the 1940s through the 1960s, and many homes still have the small electrical service of that era. Adding electric appliances usually starts with a panel review.
HAXX calculates existing and planned loads first. Some homes can add a heat pump or charger without a service upgrade.
Original fuse boxes, Federal Pacific, Zinsco and worn split-bus panels are reasons to replace equipment regardless of new loads.
The City of Daly City lists electrical service upgrades among its quick permits. HAXX applies, schedules PG&E and meets the inspector.

“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.”

Electrical service upgrades are listed as a quick permit through Daly City's online permit portal. HAXX handles the application and inspection.
Typically about one working day for the changeover, depending on PG&E scheduling.
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.
