CONCORD DETAILSPanel upgrades for
Panel upgrades for
Concord homes.
Much of Concord was built from the 1950s through the 1970s with panels sized for gas appliances. Adding electric loads often starts here.
01
Load calculation first
HAXX calculates your actual load before recommending a bigger service. Sometimes load management or a smart panel avoids a full upgrade.
02
Older panels
Panels from the 1960s and 1970s can have worn breakers, aluminum branch wiring or no room for new circuits. HAXX inspects and explains what it finds.
03
Permits and PG&E
HAXX applies for the electrical permit through Concord's ePermit Online portal and coordinates any service change with PG&E.

“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!”
★★★★★

GOOD TO KNOW
Electrical Panel Upgrade in Concord: questions, answered.
Will a heat pump force me to a 200-amp service?
Not always. Many Concord homes fit a heat pump on the existing service after a load calculation. HAXX will tell you which applies.
Is a permit needed to upgrade a panel in Concord?
Yes. It requires an electrical permit and inspection, and service changes need PG&E coordination. HAXX handles both.
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.
