Load calculation
A written load calculation of existing and planned appliances, so you know whether you need more capacity at all.
Breakers tripping or no room for a heat pump or EV charger in a San Pablo home? HAXX upgrades panels and services and coordinates with PG&E.
Serving Hasford Heights, the Rumrill Boulevard area, Road 20 and Church Lane near Contra Costa College, plus nearby Rollingwood and Tara Hills and the rest of San Pablo. 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Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
City of San Pablo permit records include both like-for-like 100-amp panel replacements and upgrades to 200-amp service, which reflects how varied the city's older wiring is.
HAXX calculates the current and planned load before recommending a new service, so you only upgrade when it is needed.
Swapping an outdated panel and raising the service size are different jobs. Each is quoted separately and explained.
Electrical permits go through eTRAKiT. Service upgrades also require PG&E disconnect and reconnect scheduling.

“The technician from Haxx immediately pointed out multiple violations of the National Electrical Code and explained that the wiring was overheating and could potentially become a fire hazard. They offered to redo the installation the correct way, pulled the proper permit, and installed the EV charger safely and professionally. The city inspection passed without any issues.”
“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!”

It depends on the house and the appliances. Some homes manage on 100 amps with load management, while others need 200 amps. A load calculation decides.
Yes. Panel and service work requires a City of San Pablo electrical permit and inspection before PG&E reconnects power.
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.
