MAIN 200AElectrical Panel Upgrade in Los Angeles, CA
A lot of Los Angeles houses are still running the panel they were built with, on a service sized for one window AC and a black-and-white television. Add an EV, a heat pump and an induction range and that panel is out of room and out of capacity.
Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

Situations we see in Los Angeles
Adding an EV, heat pump or ADU
All of these need a load calculation. If existing demand plus the new load exceeds your service, the upgrade comes first.
Panel is rusted or wet
Water in an enclosure corrodes bus stabs and creates high-resistance connections. Once rust reaches the bus, the panel is done.
Zinsco or Federal Pacific panel
These breakers have a documented history of failing to trip under fault. Replacement is the only real remedy, and it is one of our most common Los Angeles jobs.
No space left in the panel
Double-tapped breakers and tandem cheaters are a sign the panel is full. A 200 amp replacement gives you 40 or more spaces and room for the next ten years.

Reviews from Los Angeles County
Added outlets to three bedrooms and a weatherproof one out back. Cuts were small, patches were tidy, and everything got labeled at the panel.
Hugo S.Outlet installation · Los AngelesOur restaurant lost the walk-in circuit on a Friday. They came out after close, traced it to a failed feeder lug, and we opened Saturday on time.
Ken A.Commercial repair · Los AngelesBought a 1948 house with cloth wiring. They phased the rewire so we always had power in half the house, and gave us paperwork our insurer accepted.

Do I need a permit for a panel upgrade in Los Angeles?
Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.
How long will my power be off during the upgrade?
Plan on most of a working day. We coordinate the utility disconnect and reconnect so the outage lands in one block rather than spread over days.
Do I really need 200 amps?
If you are adding EV charging, electric heat, a hot tub or an ADU, almost certainly. We run an actual load calculation rather than guessing, and if 100 amps genuinely still works we will tell you.
How much does an electrical panel upgrade cost in Los Angeles?
Cost tracks the service size, the condition of the service entrance and whether the meter has to move. A straight 100 to 200 amp swap sits well below a job that needs a new mast and underground feed. Call (833) 652-8933 and we will walk your panel and quote a flat number.
Can you replace just the breakers instead of the whole panel?
Sometimes. On a sound modern panel, breaker replacement is fine. On a Zinsco, Federal Pacific or corroded enclosure, new breakers don't fix the bus, so the panel gets replaced.
