Electrical Panel Upgrade Contractors in Carrollton, TX

Not every electrician in Carrollton does panel upgrades — and of those who do, not all of them pull permits, perform load calculations, or coordinate with Oncor correctly.

This page lists electricians serving Carrollton, TX who perform electrical panel upgrades, along with TDLR license numbers so you can verify their credentials before calling. For help evaluating and comparing contractors, see the How to Choose guide.

What to Expect Before You Call

Three things every legitimate Carrollton panel upgrade involves — ask about these before scheduling:

What to Confirm	What It Means	Red Flag
City of Carrollton permit	All panel upgrades require a permit pulled before work starts	Contractor suggests skipping permit or calling it "optional"
Oncor service disconnect coordination	Oncor must disconnect power before panel replacement; must be scheduled 2–3 business days ahead	Contractor doesn't mention Oncor or can't explain the process
Load calculation performed	Contractor assesses existing electrical load before recommending amperage	Contractor recommends amperage without an in-person assessment

Timeline to expect: Permit pull → Oncor scheduling → installation → inspection = typically 5–10 business days from signed contract to final inspection.

Verifying a TDLR License Before You Call

All electricians performing panel work in Texas must hold an active Electrical Contractor license from TDLR. Verify any contractor in 2 minutes:

1. Go to tdlr.texas.gov
2. Click "License Holder Search"
3. Enter the license number from the listing above (or ask the contractor for theirs)
4. Confirm status: Active and license type: Electrical Contractor

If a contractor can't provide their TDLR license number before scheduling, that is a disqualifying red flag. See How to Choose a Panel Upgrade Electrician in Carrollton for the full vetting framework including the quote comparison scorecard and DFW-specific red flags.

What Makes a Good Panel Upgrade Electrician?

Three non-negotiable signals — beyond star ratings:

1. TDLR Electrical Contractor license is active — Verify yourself at tdlr.texas.gov. No license number = no booking.
2. Permit pull is included in scope — Ask directly. A contractor who suggests skipping the City of Carrollton permit is operating outside city code.
3. Oncor coordination is in the process — Every DFW panel upgrade requires Oncor to disconnect the service feed. Ask: "What's your Oncor scheduling process?" If they can't answer, find someone who can.

For the full 10-question vetting checklist, quote comparison scorecard, and DFW-specific red flags: How to Choose an Electrician for a Panel Upgrade in Carrollton, TX

Q: How do I verify an electrician's license in Texas? Use the TDLR license lookup at tdlr.texas.gov/LicenseSearch. Search by name or license number. Confirm the Master Electrician license (not just journeyman) is active and not expired or suspended. Also verify the Electrical Contractor (EC) license for the company.

Q: How long does a panel upgrade take in Carrollton? The physical swap typically takes 4–8 hours for a standard 200-amp upgrade. Add time for permit issuance (1–3 business days) and CenterPoint disconnect/reconnect scheduling (usually same-day or next-day). Total project timeline from contract to restored power is typically 3–7 days. Homes with additional complications (service entrance replacement, subpanel work) may take 1–2 days of active labor.

Q: What should be included in a Carrollton panel upgrade contract? Must include: itemized scope (panel model, breaker count, meter base included/excluded, permit and inspection fees), payment schedule (typically 50% at start, 50% at completion), TDLR license number, CenterPoint coordination responsibility, warranty terms (minimum 1 year labor, manufacturer warranty on panel), and timeline with start date.

Q: Who handles the power shutoff and restore during a panel upgrade in Carrollton? CenterPoint Energy performs the meter pull (power disconnect) and reconnect. Your licensed electrician coordinates this directly with CenterPoint. As a homeowner, you do not need to contact CenterPoint separately. The reconnect is typically scheduled for the same day as the work, so your home should not be without power overnight in normal circumstances.

Q: Does my homeowner's insurance need to know about a panel upgrade in Carrollton? Yes — notify your insurer after completion. A permitted and inspected panel upgrade can reduce your insurance premium (some insurers discount homes with updated 200A panels). If you don't notify your insurer and a future claim involves the electrical system, coverage disputes can arise over whether the work was properly permitted.
