Electrical Panel Upgrades in San Antonio
Old panels can limit your home and create safety concerns. We upgrade electrical service with careful planning, clean installation, and proper testing.
A Panel Upgrade Planned Around Your Home
Replacing a panel is not a one-size-fits-all job. We assess your service size, panel location, connected loads, grounding, and future plans before recommending equipment. That approach helps prevent costly surprises and gives your home the capacity it actually needs.

San Antonio Homeowners Trust Clean, Careful Upgrades
Arnold's Electrical Service replaced our outdated panel in Terrell Hills and cleaned up every wire before leaving. The whole job was finished in one day.
Our lights kept flickering in Stone Oak. Arnold found the loose connection, explained the repair clearly, and had everything working safely that afternoon.
We hired Arnold's Electrical Service to install an EV charger in Alamo Heights. The placement is tidy, the pricing was clear, and charging at home has been easy.
What to Know Before Replacing Your Panel
When does a home need an electrical panel upgrade?
Common signs include frequent breaker trips, an overloaded panel, insufficient capacity for new appliances, obsolete equipment, heat or damage, and plans for an EV charger or major remodel.
How long does a panel upgrade take?
Many residential upgrades can be completed in one working day, but timing varies with service changes, utility coordination, access, permits, and the condition of existing wiring.
Will my power be off during the upgrade?
Yes. The service must be safely de-energized during the replacement. We explain the expected interruption before scheduling the work.
Can you add circuits during a panel upgrade?
Often, yes. We can discuss dedicated circuits for appliances, workshops, HVAC equipment, home offices, or EV charging as part of the overall load plan.
