Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Many San Jose homes from the 1950s to 1970s still have 100-amp service and full panels. Electrification projects are the most common reason homeowners call.
A load calculation shows whether your current service can carry new equipment, sometimes with load management, before you pay for a service upgrade.
HAXX files the City of San Jose electrical permit, schedules the inspection and coordinates the PG&E work order for service changes.
Older panels and full panels in garages and side yards are common in San Jose ranch homes. Location and clearances are part of the plan.

“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!”
