Electrical Safety in Texas Heat: When to Upgrade to a 200-Amp Panel
Between modern EV chargers, pool pumps, and dual-zone air conditioners running constantly, why older 100A Texas homes need modern electrical panels.
Thousands of homes built before 1995 across Texas still operate on 100-amp or 125-amp breaker boxes. When summer temperatures exceed 100 degrees, simultaneous AC draw, induction stoves, and EV charging can cause dangerous panel overheating or continuous breaker trips.

A whole-home 200A service upgrade ensures safe, clean power distribution, compliance with current NEC electrical codes, and headroom for solar integrations and battery storage systems.
