FAIRFIELD DETAILSPanel upgrades for
Panel upgrades for
Fairfield homes.
Older homes in central and north Fairfield often have smaller panels that already carry central AC. Adding a heat pump, EV or induction range makes capacity the first question.
01
Load calculation
HAXX measures what the panel can carry before recommending an upgrade. Some homes need one, many do not.
02
Permit and inspection
Service upgrades are permitted through the City of Fairfield. The inspector also verifies smoke and CO alarms at the final.
03
PG&E coordination
HAXX schedules the PG&E disconnect and reconnect so the outage stays as short as possible.

★★★★★
“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 Fairfield: questions, answered.
Does a panel upgrade need a permit in Fairfield?
Yes. HAXX files it with the City of Fairfield, coordinates with PG&E and meets the inspector.
Why does the inspector check smoke alarms?
California requires smoke and CO alarms in required locations, and Fairfield verifies them during residential permit inspections.
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.
