For a burning smell and power loss, we treat it as a critical dispatch. From a landmark like the library, we can use I-57 for a direct route, typically arriving within 5-8 minutes in Markham. Your first action should be to turn off power at the main breaker if safe to do so. This immediate response is crucial to prevent an electrical fire from starting.

Overhead service masts, common in Markham's older neighborhoods, are exposed to the elements. The mast head can corrode, and the connection where the utility's drop line attaches can loosen over time, potentially causing arcing. We also inspect the mast's structural integrity; if it's sagging or damaged, it may not support the newer, heavier service cables required for a panel upgrade.

Safely adding a heat pump or Level 2 EV charger requires a service upgrade. Your existing 100A panel is already at capacity for a 1964 home, and we must first check for a Federal Pacific panel, which is a known fire hazard and requires immediate replacement. A modern 200A service with a new panel creates the necessary capacity and safety foundation for those high-demand appliances.

All panel upgrades require a permit from the Markham Building Department, and the installation must comply with the 2023 NEC. As a master electrician licensed by the Illinois Department of Financial and Professional Regulation, I handle the permit application and scheduling of the required inspections. This ensures the work is documented, safe, and adds value to your home.

The flat terrain itself doesn't directly cause issues, but it can influence grounding. Proper grounding requires driving rods into soil that may have varying moisture content. More relevant is that open prairie offers no wind break for the overhead service lines feeding your home, making them susceptible to damage during severe straight-line winds, which can lead to prolonged outages.

This points to grid-level surges, which are common with the moderate, seasonal thunderstorms here. While ComEd manages the main grid, surges enter your home and can damage sensitive electronics. Installing a whole-house surge protector at your main panel is the professional solution. It acts as a first line of defense, clamping down on those voltage spikes before they reach your devices.

Your cloth-jacketed copper wiring is over 60 years old, which is the core issue. While that wiring was reliable for its era, it was never designed to handle the simultaneous loads of a modern 2026 household. The insulation becomes brittle over time, increasing fire risk. Upgrading the wiring and your 100A service panel is the only way to safely support today's appliances.

For winter ice storms, ensure your backup generator has a proper transfer switch installed to prevent back-feeding the grid, which is lethal to utility workers. In summer, brownouts from AC demand cause low voltage that can overheat motors in your fridge or AC unit. A licensed electrician can install protective devices that monitor voltage and automatically disconnect circuits to prevent damage during these events.
