Panel Upgrade · San Dimas, California
An electrical panel upgrade in San Dimas 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 San Dimas, California.
Scope of work
Whether you searched for electrical panel upgrade San Dimas, electrical panel replacement San Dimas or simply electrician near me, this is the crew that turns up. We work across San Dimas 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
They did our tenant improvement over three nights so we never closed. Panel, subpanel, twenty new circuits and all the display lighting. Invoiced exactly what was quoted.
Recessed lighting in a vaulted living room, which everyone else told me would need a soffit. They laid it out, showed me the spacing on paper first, and it looks like it came with the house.
Generator install went in ahead of the schedule they gave us. Transfer switch cut over during the October shutoff without us noticing until we saw the neighbours' lights out.
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 San Dimas 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 San Dimas homes.
Three common causes: too much load on one circuit, a short somewhere on the run, or a failing breaker. A breaker that trips instantly on reset usually means a short and should not be reset repeatedly. Call (888) 592-6466 and we will trace it.
Both. Residential work covers repairs, remodels, rewires and installations. Commercial work covers offices, retail, restaurants and warehouses in San Dimas, and we schedule it outside your trading hours where we can.
