Upgrading electrical service to 200 amps is priced after an on-site evaluation, because final cost depends on your existing panel, service entrance, and utility requirements. The biggest driver is whether your home already has a meter base and service drop/lateral that can support 200 amps; if not, utility coordination and material changes add time and parts. Many homes also need grounding/bonding updates or a new main panel, while some can defer a full upgrade with dedicated circuits or managed-load devices. Our licensed team completes 200‑amp upgrades around the San Antonio area near Converse and handles permitting and inspections. Free surge protector with purchase of any panel or full electrical service upgrade ($795 value).
Key cost drivers we confirm during the visit:
- Panel replacement vs. relocation and amperage rating
- Meter base, service mast or conduit, and wire size to 200A
- Trenching or riser work for underground/overhead feeds
- Grounding, bonding, AFCI/GFCI updates, and utility scheduling

The cost to replace a fuse box (upgrade to a modern breaker panel) varies by home and scope. We provide upfront, transparent pricing after an in‑home evaluation by a licensed electrician (TDLR #40048). Factors include the panel’s condition and any needed wiring or safety corrections. We can start the same day and offer financing. New customers may get $50 off electrical repairs when applicable. Our Home Comfort Club includes an electrical inspection that can identify issues before pricing in San Antonio and New Braunfels.
