How It Works

Our Panel Upgrade Process

We follow a clear, structured approach so every San Antonio panel upgrade is completed safely, efficiently, and to code.

01Step 1

On-Site Assessment

We visit your San Antonio property to evaluate your current panel, service entrance, load requirements, and any existing wiring concerns before recommending a solution.

02Step 2

Upgrade Plan and Scope

Our electricians outline the specific panel upgrade needed — including amperage, breaker configuration, and any related work — so you know exactly what to expect.

03Step 3

Safe Panel Replacement

We coordinate the utility disconnect, remove the old panel, and install your new electrical panel following all San Antonio and TX electrical codes.

04Step 4

Testing and Inspection

Once installed, we thoroughly test every circuit, verify proper labeling, and confirm the system meets code requirements before restoring power to your property.

Frequently asked

Panel Upgrade Questions Answered

Common questions get answered quickly so the page feels more trustworthy before someone reaches out.

Q1

How do I know if my panel needs an upgrade?

Common signs include frequently tripping breakers, flickering lights, a fuse box instead of a breaker panel, or struggling to power modern appliances. If your home is older or you're adding high-demand equipment, a panel upgrade is often necessary.

Q2

What amperage panel does my San Antonio home need?

Most modern homes benefit from a 200-amp service, especially if you're running large appliances, HVAC systems, or plan to install an EV charger. Our electricians assess your actual load requirements before making a recommendation.

Q3

Will I need a permit for a panel upgrade in San Antonio?

Yes, panel upgrades in San Antonio, TX typically require a permit and inspection. Classic Electric Co. handles the permitting process and ensures all work meets local code requirements.

Q4

How long does a panel upgrade typically take?

Most residential panel upgrades are completed in a single day. More complex installations or those requiring utility coordination may take additional time. We'll give you a clear timeline before work begins.

Q5

Can a panel upgrade support an EV charger installation?

Absolutely. EV chargers — especially Level 2 units — require dedicated circuits and adequate amperage. Upgrading your panel first ensures your electrical system can safely support EV charging without overloading existing circuits.

Q6

Is my power turned off during the panel upgrade?

Yes, power to your home or business must be shut off during the panel replacement. We coordinate with the utility provider for the disconnect and work efficiently to minimize downtime.

Q7

Do you upgrade panels in commercial properties as well?

Yes. Classic Electric Co. performs panel upgrades for both residential and commercial properties throughout San Antonio, TX, handling the increased demands that commercial electrical systems often require.

Q8

What happens if my wiring is outdated when we upgrade the panel?

Our electricians will flag any wiring concerns during the assessment. In some cases, older wiring may need to be addressed alongside the panel upgrade to ensure the entire system operates safely and to code.
