Panel upgrades in
Antioch.
Panel needs vary across Antioch. Older homes near Downtown often have small services, while 1980s to 2000s homes in Dallas Ranch and Lone Tree may simply be out of breaker space.
01
Load calculation
The City's residential checklist calls for service and load calculations with electrical plans. HAXX does this first, and it often shows an upgrade is not needed.
02
Outdated equipment
Federal Pacific, Zinsco and worn split-bus panels are replaced rather than patched.
03
PG&E coordination
Service upgrades require a PG&E disconnect and reconnect. HAXX schedules it with the inspection.

★★★★★
“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.”

GOOD TO KNOW
Electrical Panel Upgrade in Antioch: questions, answered.
Does a panel upgrade in Antioch need a permit?
Yes. HAXX submits electrical plans with load calculations to the City of Antioch, coordinates PG&E and meets the inspector.
How long will the power be off?
Plan on most of one working day. The exact window depends on when PG&E can disconnect and reconnect the service.
Do I need 200 amps?
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.
How long does a panel upgrade take?
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
