Your home's original electrical system is now 30 years old. The NM-B Romex wiring from 1996 was installed for the appliance loads of that era, not the combined demands of today's high-draw devices like induction cooktops and tankless water heaters. Dimming lights are a clear sign the circuit is overloaded and the voltage is dropping. Upgrading specific branch circuits or your main service may be necessary to handle modern 2026 electrical consumption safely.

Flickering can originate from both the utility grid and your home's wiring. Given the high lightning surge risk in our area, CoServ's grid can experience voltage fluctuations. However, consistent flickering when a major appliance cycles on usually points to a loose connection in your home, often at the main service lugs, a failing breaker, or an overloaded circuit. A whole-house surge protector installed at your panel is also a critical defense for your sensitive electronics against grid-borne surges.

For summer brownouts, ensure your HVAC system is serviced and consider a hard-wired surge protector to guard against voltage sags and spikes. For winter ice storms, a permanently installed generator with a transfer switch is the safest backup for sump pumps, furnaces, and refrigerators. Portable generators must never be connected to your home's wiring without a proper transfer switch, as backfeed can electrocute utility workers and destroy your home's electrical system.

Yes, the flat prairie plains and clay soil common around Lewisville Lake Park directly impact grounding effectiveness. Clay can retain moisture, which is good for conductivity, but it also expands and contracts, which can physically displace or break underground grounding rods over time. We test ground resistance to ensure your grounding electrode system meets NEC standards, providing a safe path for fault currents and stabilizing your whole electrical system.

For a burning smell, we treat it as a fire hazard emergency and dispatch immediately. From Lewisville Lake Park, we're typically on the road in minutes, using I-35E to reach most Castle Hills addresses within 15-20 minutes. Our priority is to secure your home by killing power to the affected circuit at the panel and diagnosing the fault before it escalates. Please evacuate the area around the outlet until we arrive.

It depends heavily on your panel's brand and its available capacity. A 150-amp service from 1996 may already be near its limit with central AC. Adding a 50-amp EV charger and a heat pump often requires a service upgrade to 200 amps. Crucially, if your panel is a Federal Pacific brand, it must be replaced immediately regardless of your plans, as its breakers are known to fail to trip during overloads, posing a severe fire risk.

Any service panel upgrade or replacement requires a permit from the City of Lewisville Building Inspection Division. The work must comply with the NEC 2023, which includes updated rules for AFCI and GFCI protection. As a Master Electrician licensed by the Texas Department of Licensing and Regulation (TDLR), I handle the permit application, scheduling of inspections, and ensure the installation meets all current safety codes, which is mandatory for both legality and your insurance coverage.

Your underground lateral service is common in Castle Hills and is generally more reliable and aesthetically pleasing than overhead lines. The key points are the integrity of the conduit where it enters the home and the accessibility of the meter main panel for utility workers. Any excavation near the service line requires calling 811 to locate it. If you need a service upgrade, the existing underground conduit can often be reused, which simplifies the project.
