Panel Upgrade · Costa Mesa, California
An electrical panel upgrade in Costa Mesa is usually the fix when your home keeps outgrowing its service: an EV charger, a heat pump, a kitchen remodel or a second AC unit all pull more than an older board was built for. We handle 100 amp to 200 amp upgrades, breaker box replacement and fuse box removal throughout Costa Mesa, California.
Scope of work
Whether you searched for electrical panel upgrade Costa Mesa, electrical panel replacement Costa Mesa or simply electrician near me, this is the crew that turns up. We work across Costa Mesa and the neighbouring California towns, and we give you the price for the described work before anything starts.
How it goes
Tell us what is happening and where. Emergencies get triaged on the phone — sometimes the first thing we do is tell you which breaker to shut off before we arrive.
We open the panel, test the affected circuits and tell you what is actually wrong, including the parts you would rather not hear.
One number for the work described, before it starts. Options where there are options — the repair now versus the replacement that stops it recurring.
We do the job, label the circuits, clean the space and walk you through what changed and what to watch for.
Reviews
Ceiling fans in four bedrooms, none of which had fan-rated boxes. They braced every one properly instead of just hanging them off the old box.
Called at 11pm with half the house dead and a smell coming off the panel. Someone answered, and a van was outside by half midnight. Found a burnt neutral, isolated it that night and came back Tuesday to do it properly.
Two EVs, one 100 amp panel, and three other companies who said it could not be done. Ascot did the load calc, upgraded the service and put in load-sharing chargers. Both cars charge overnight now.
Questions
It depends on whether the meter, service entrance and grounding all get replaced alongside the panel, and on what the utility requires at your address. We price it after looking at the existing service — panel-only swaps sit at the low end, full 100 to 200 amp service upgrades with a new meter-main at the high end.
Most residential panel upgrades in Costa Mesa are a one-day job with the power off for a good part of it. Where the utility has to disconnect and reconnect the service drop, the schedule follows their availability, which we coordinate.
If you are adding an EV charger, a heat pump, a second AC unit or an ADU, usually yes. If you are simply replacing an obsolete panel and your load is unchanged, a like-for-like service can be enough. We run the load calculation rather than guessing.
Almost always, once you are doing any meaningful work. Fuse boxes cap capacity, have no AFCI or GFCI protection at the board, and complicate insurance and resale on Costa Mesa homes.
We cover Costa Mesa itself, its surrounding neighbourhoods and the towns nearby. Ascot Electricians works across California, so if you are just outside the city limits, call (888) 592-6466 and we will confirm coverage in a minute.
Yes. EV charger installation in Costa Mesa includes a load calculation on your existing service, the dedicated circuit, and the Level 2 charger, Tesla Wall Connector or NEMA 14-50 outlet. If the panel cannot carry it, we will tell you what the upgrade costs before you commit.
