How It Works
A panel upgrade is a straightforward process when it's handled by someone who knows what they're doing. Here's what to expect when you work with Classic Electric Co.
We start by reviewing your current panel, evaluating your electrical load, and identifying whether a full replacement or targeted upgrade is the right solution for your property.
Once we understand what's needed, we walk you through the scope of work before scheduling. No surprises on the day of the job.
Our electricians handle the full installation, including disconnecting the old panel, installing the new one, reconnecting circuits, and verifying everything is properly labeled and functional.
We confirm the completed work meets current TX electrical code requirements. If a permit or utility coordination is required, we handle that as part of the process.
Frequently asked
Common questions get answered quickly so the page feels more trustworthy before someone reaches out.
Q1
Common signs include frequently tripping breakers, flickering lights, a panel that feels warm to the touch, or a fuse box that hasn't been updated in decades. If you're adding high-draw appliances or an EV charger, a capacity upgrade may be needed.
Q2
Most modern homes run comfortably on a 200-amp panel. Older homes with 60 or 100-amp service often benefit from upgrading, especially if you're running central AC, electric appliances, or planning to add an EV charger.
Q3
Yes, most panel upgrades in San Antonio, TX require a permit. Classic Electric Co. handles the permitting process as part of the job so you don't have to track that down yourself.
Q4
Most residential panel upgrades are completed in a single day. Larger commercial jobs or cases requiring utility coordination may take longer. We'll give you a realistic timeframe before we start.
Q5
Yes, power to your home or the affected circuits will be off during the installation. We work efficiently to minimize downtime and let you know in advance how long to expect the outage to last.
Q6
Absolutely. EV chargers, particularly Level 2 units, draw significant power. If your current panel doesn't have the capacity, upgrading it first is the right move. We handle both services and can coordinate them as one project.
Q7
A panel upgrade replaces or expands your breaker panel. A service upgrade increases the amperage coming into your home from the utility. Sometimes both are needed, and Classic Electric Co. can assess which applies to your situation.
Q8
Yes. Classic Electric Co. works with both residential and commercial clients throughout San Antonio. Commercial panel upgrades follow a similar process but are scoped to the higher demand loads businesses typically require.
