Best Electrical in Plano, TX — 18 Vetted Contractors

Yes. Per the City of Plano Development Services / Building Inspections division, a permit is required for electrical panel upgrades, service changes, and new circuit installations. The permit triggers an inspection by a city inspector, which protects you legally and at resale. Any licensed electrician operating in Plano should pull this permit as a standard part of the job — it's not optional, and a contractor who suggests skipping it is a red flag.

Use the free license lookup tool at tdlr.texas.gov — the Texas Department of Licensing and Regulation regulates all electrical contractors in the state. Search by name or license number. You want to confirm the license is active, not expired or suspended. The individual doing the work should hold at least a Journeyman Electrician license; the company should have a Master Electrician on staff or as the license holder.

Possibly. Homes built in Plano between roughly 1965 and 1978 may have aluminum branch circuit wiring, which was common during a period of high copper prices. Aluminum wiring isn't automatically dangerous, but it requires aluminum-rated outlets, switches, and connections. Improperly terminated aluminum wiring is a documented fire risk. Have a licensed electrician do a wiring assessment — they'll check terminations, look for signs of overheating, and tell you whether remediation (COPALUM crimping or CO/ALR device replacement) is needed.

Based on regional cost data for the DFW market, expect $1,200–$2,800 for a 200-amp panel upgrade in Plano. The range depends on whether the meter base needs replacement, whether Oncor needs to disconnect and reconnect service (which adds coordination time), and the condition of the existing wiring. Get at least two itemized quotes. Be cautious of bids under $1,000 — they often exclude permit fees, Oncor coordination, or necessary meter base work.

For a straightforward garage installation with an existing 200-amp panel and available breaker space, expect $400–$900 installed in Plano. If you need a sub-panel added, a long conduit run, or a panel upgrade first, costs rise accordingly. A permit is required for this work in Plano. Some EV manufacturers and utilities offer rebates — check with Oncor and your EV manufacturer for any current incentives before booking.

Given North Texas's active spring storm season and the frequency of lightning-related power surges in the DFW area, most Plano electricians consider whole-home surge protection a high-value upgrade. Installed at the main panel, it protects all circuits in the home. Typical installed cost in Plano is $200–$500 depending on the device and labor. It won't protect against a direct lightning strike to your service entrance, but it handles the far more common utility-side surges that kill appliances and electronics.

It can be both, and a licensed electrician should be your first call. Common electrical causes include a breaker that's worn and tripping below its rated amperage, a loose connection at the disconnect box or panel causing resistance heat, or a dedicated circuit that's undersized for the actual draw of the unit. The HVAC technician can rule out a failing compressor drawing excess current. In Plano's summer heat, this issue is common — don't ignore it, as a failing breaker that stops tripping is more dangerous than one that trips.

In May 2026, expect 1–3 week lead times for non-emergency residential work from reputable licensed electricians in Plano. Pre-summer demand for panel assessments, HVAC circuit work, and EV charger installs peaks in May. For genuine safety emergencies — burning smell, sparking outlets, loss of power to critical circuits — call and explain the situation; most contractors triage safety calls. If you have flexibility, booking in late April or early June typically means shorter waits.
