Electrical Panel Upgrades in Celina & Collin County, TX

A panel doesn't usually fail all at once - it tells you first. Common warning signs we see on service calls across Collin County:

• Breakers that trip repeatedly, especially when running the microwave, AC, and a hair dryer at the same time
• A panel still rated at 60 or 100 amps in a home with central air, an electric range, or a growing number of devices
• Warm, discolored, or buzzing breakers and panel covers
• Flickering or dimming lights when large appliances kick on
• A panel brand with a known history of failure (Federal Pacific, Zinsco, some Sylvania) - see our breaker & panel repair page for more on hazard brands
• Rust, corrosion, or evidence of past water intrusion inside the panel
• Wanting to add an EV charger, a hot tub, or a home addition and being told the existing service can't support it

If any of that sounds familiar, it's worth having a licensed electrician actually open the panel and look, rather than guessing from the outside.

A lot of homes built in Collin and Denton County before the 1990s were wired for 100-amp service, which was adequate for the appliance load of that era. Today, 200-amp service is the standard for a modern home, and for good reason - it gives you headroom for central AC, an electric range, a workshop, and an EV charger without constantly juggling what's running at once.

According to the U.S. Department of Energy, electrical demand in the average home has climbed steadily as households add more electronics, HVAC capacity, and now EV charging - which is exactly why so many DFW homeowners are upgrading proactively rather than waiting for a failure.

Panel work is one of the few electrical jobs in Texas that always requires a permit, and we treat that as a feature, not a hassle - it means a third party confirms the work was done correctly before your walls close back up. Our process:

1. On-site evaluation - We inspect your existing panel, wiring, grounding, and service entrance, and talk through what you actually need (EV charger, hot tub, addition, or just peace of mind).
2. Permit pulled - We handle the paperwork with the local building department; typical TX electrical panel permits run roughly $50-$300 depending on the municipality.
3. Coordination with the utility - Larger upgrades sometimes require a brief service disconnect coordinated with the utility company; we schedule this to minimize downtime.
4. Installation - We install the new panel, breakers, grounding, and bonding to current code, sized for your household's real load.
5. Inspection - A local inspector reviews and signs off on the work, which is your documentation that the job was done to code - important for insurance and resale.

The Texas Department of Licensing and Regulation oversees electrical licensing in Texas, and permitted, inspected work is part of how that system protects homeowners.

Every home is different, but homeowners researching this project should know the general range before they start calling around. See our full panel upgrade cost guide for a deeper breakdown, or request a free, no-pressure quote for your specific home.

A panel upgrade isn't usually the end goal - it's what unlocks everything else. Homeowners typically upgrade so they can add an EV charger or Tesla Wall Connector, install a whole-home surge protector, run a larger AC system, add a hot tub, or finish a garage workshop without tripping breakers constantly. If you're in Prosper, Frisco, or anywhere in our Collin County service area, and you're not sure whether your current panel can support what you're planning, that's exactly the kind of question we're happy to answer on-site before you commit to anything.
