Homes from 1977, like many in Downtown Mexia, were wired with NM-B Romex for the loads of that era—often just a few major appliances. Your 49-year-old electrical system wasn't designed for the simultaneous demands of 2026, which can include multiple computers, large-screen TVs, and high-efficiency HVAC systems all running at once. This can cause voltage drops, seen as dimming lights. A 100-amp panel, common for the time, may now be operating at its functional limit.

Yes, the rolling prairie terrain around Downtown Mexia can impact your system. Rocky or very dry soil can lead to a high-resistance ground, compromising the safety path for fault currents. Heavy tree canopy near overhead service drops, common in older neighborhoods, can cause line interference and increase the risk of limbs falling on conductors during storms. A proper evaluation includes testing your grounding electrode system and ensuring tree trimming maintains a safe clearance from utility lines.

Any service panel upgrade or replacement in Mexia requires a permit from the City of Mexia Building Inspections Department and a final inspection. The work must comply with the 2020 National Electrical Code (NEC), which Texas follows, and all work must be performed by a Master Electrician licensed by the Texas Department of Licensing and Regulation (TDLR). We handle the permit paperwork and ensure the installation, from the grounding electrodes to the AFCI breakers, meets all current safety standards.

Overhead service masts, standard for 1977 construction, are exposed to the elements and physical strain. Over decades, weathering can loosen masthead connections, and ice or wind can stress the mast itself, potentially pulling it away from the structure. The service drop wires also sag over time. Any damage here is before your meter, so repairs require coordination with Oncor. We inspect the mast's integrity, the weatherhead seal, and the mast's attachment to the house framing during any service evaluation.

For summer peaks, ensure your HVAC system is on a dedicated, properly sized circuit and consider having an electrician evaluate your panel's load calculation. For extended outages from ice storms, a permanently installed generator with an automatic transfer switch is the most reliable solution. It must be installed with a proper interlock kit to prevent back-feeding the grid, which is a deadly hazard to utility workers. Whole-house surge protection is also wise year-round given our local storm frequency.

A burning smell indicates an active electrical fault, which is an immediate safety priority. From our dispatch point near Mexia City Hall, we're typically on US Highway 84 and can be at most Downtown locations within 3 to 5 minutes for an emergency call. The first step is to shut off the main breaker at your meter if it's safe to do so, then we'll diagnose the fault at the panel or service entrance to prevent a fire.

Safely adding a heat pump or Level 2 EV charger to a 1977 home with a 100-amp service is very difficult and often requires a full service upgrade. These devices add significant, continuous loads that your existing panel's bus bars and main breaker are not rated to support. Furthermore, if your panel is a Federal Pacific brand—common in homes of that vintage—it must be replaced immediately due to known failure and fire hazards, which makes the service upgrade a critical safety step anyway.

The Oncor grid in our rolling prairie region experiences high lightning-related surge activity. While some fluctuation is on the utility side, your home's first line of defense is its internal protection. Modern electronics are sensitive, and old wiring or missing whole-house surge protection leaves them vulnerable. We recommend installing a Type 1 or Type 2 surge protective device at your service entrance to absorb major grid spikes before they reach your smart home panel and delicate equipment.
