Electrical Panel Upgrade in San Antonio, TX

Most San Antonio homes that still run on 100-amp service do not have enough capacity for today's appliances, HVAC systems, and home offices. If your breakers trip regularly or you plan to add high-draw equipment, upgrading to 200-amp service is the practical move.

Yes, a modern panel can improve your home's position during appraisal and buyer inspections in San Antonio. Outdated or undersized panels often show up on inspection reports and give buyers a reason to negotiate your asking price down.

The federal 25C Energy Efficient Home Improvement Credit for panel upgrades expired on December 31, 2025, so new 2026 installations no longer qualify for that credit. If your panel upgrade was completed in 2025 alongside a qualifying energy improvement like a heat pump, you may still be able to claim up to $600 when you file your 2025 federal return using IRS Form 5695 — consult a tax professional to confirm your eligibility.

Panel work involves live utility lines and carries serious risk of electrocution or fire if handled without proper training and tools. In San Antonio, this work also requires an inspection, so a DIY attempt that fails inspection can cost more to correct than hiring a professional from the start.

Frequent breaker trips, lights that dim when large appliances start, a panel that feels warm to the touch, or a fuse box instead of a breaker panel all point toward an upgrade rather than a simple repair. If you are adding square footage, a new HVAC system, or an EV charger in San Antonio, your existing panel capacity should be assessed before that work begins.

In most cases, old breakers are not reused because a panel upgrade is the right time to install new, properly rated breakers that match the new panel. Reusing worn breakers can defeat the purpose of the upgrade and may not meet current code requirements in Texas.
