Yes, it's a common issue. Overhead service lines running through dense tree canopy can experience interference from swaying branches, leading to momentary faults and flickering lights. Furthermore, the moist, root-filled soil in these areas can degrade grounding electrode system performance over time. An electrician can assess your service mast clearance and test your ground rod's resistance to ensure safety.

Your electrical system is about 46 years old, installed around 1980. Original NM-B Romex wiring from that era, while functional, was sized for the smaller appliance loads of its time. Modern kitchens, home offices, and HVAC systems draw far more current, often causing voltage drop that manifests as dimming lights. Upgrading the service and key circuits can resolve this capacity issue.

The BGE grid in our area faces moderate surge risk from seasonal thunderstorms. These voltage spikes can easily bypass basic power strips and damage sensitive electronics. Whole-house surge protection installed at your main panel is the most effective defense, clamping dangerous surges before they enter your home's wiring. This is now a recommended practice in the NEC for all homes.

For summer peaks, ensure your AC system is on a dedicated, properly sized circuit and consider a hard-wired surge protector. For winter ice storms that can bring down lines, a permanently installed generator with an automatic transfer switch is the safest backup. It isolates your home from the grid, preventing backfeed, and powers essential circuits automatically, all in compliance with county codes.

From our central dispatch point near Arnold Park, we can typically be on-site in Arnold Heights within 5-8 minutes via MD-2. A burning odor indicates an active fault, such as a failing breaker or loose connection, which demands immediate attention. Please turn off the main breaker if safe to do so and meet us outside. We prioritize these calls to prevent fire spread.

A 100-amp service from 1980 is insufficient for a Level 2 EV charger, which alone can require a 40-50 amp circuit. More critically, many Arnold homes from this period have Federal Pacific panels, which are a known fire hazard due to breakers that fail to trip. A full service upgrade to 200 amps is the required first step for both safety and to accommodate modern loads like EV chargers or heat pumps.

Overhead or mast service is standard for Arnold Heights and is generally reliable. The primary considerations are ensuring the masthead is secure against weather and that tree limbs are trimmed back from the service drop conductors. While underground service is less prone to weather disruption, overhead systems allow for easier inspection and repair of the utility-owned lines leading to your meter.

Absolutely. A panel replacement is major work that requires a permit and inspection from the Anne Arundel County Department of Inspections and Permits. This ensures the installation meets NEC 2023 safety standards, is properly documented for future homeowners and insurance companies, and is performed by a licensed Master Electrician credentialed by the Maryland State Board. We handle all permitting and coordinate the final inspection.
