Electrical Panel Upgrades
100 Amp to 200 Amp & 400 Amp Panel Upgrades for Austin & Hill Country Homes
(512) 301-9111 – Free EstimateIs your home's electrical panel keeping up with your family's demands? Many Austin-area homes—especially those built before 2000—have 100-amp panels that simply can't handle today's electrical loads. Between EV chargers, home offices, smart appliances, and HVAC systems, older panels are often pushed beyond their limits.
At Malco Electric, we've been upgrading electrical panels throughout Austin and the Texas Hill Country since 1983. Led by Master Electrician Randy Mallory (Lic. #6328), our team handles everything from straightforward 200-amp upgrades to complex 400-amp service installations—including all permits, inspections, and utility coordination.
Panel Upgrade Services We Offer
100 to 200 Amp Upgrade
The most common upgrade for older Austin homes. Provides the capacity needed for modern electrical demands, EV chargers, and additional circuits.
400 Amp Service
For larger homes with pools, workshops, guest houses, or multiple HVAC systems. Often installed as two 200-amp panels.
Subpanel Installation
Add a subpanel to your garage, workshop, barn, or addition without upgrading your main service. Ideal for EV charger circuits.

When upgrading amperage, the meter base often needs replacement. We coordinate directly with Austin Energy and Pedernales Electric.

Frequently Asked Questions
How much does an electrical panel upgrade cost in Austin?
Electrical panel upgrade costs in Austin typically range from $1,500 to $4,000+ depending on the amperage increase, panel location, permit requirements, and whether the meter base needs replacement. Malco Electric provides free estimates with transparent, upfront pricing—no hidden fees or surprises.
How do I know if I need a panel upgrade?
Common signs include frequently tripping breakers, flickering lights when appliances run, a panel that's warm to the touch, burning smell near the panel, inability to add new circuits, or if your home still has a fuse box. If you're adding an EV charger, hot tub, or pool equipment, you may also need more amperage.
What size electrical panel do I need for my home?
Most modern homes require 200-amp service. Older homes with 100-amp panels often need upgrades to support today's electrical demands. Larger homes, those with EV chargers, pools, or multiple HVAC systems may require 400-amp service. We perform a load calculation to determine your specific needs.
How long does an electrical panel upgrade take?
Most residential panel upgrades take 4-8 hours to complete. The process includes coordinating with your utility for a temporary disconnect, replacing the panel and meter base if needed, and scheduling the final inspection. We handle all the logistics.
Do I need a permit to upgrade my electrical panel in Texas?
Yes, electrical panel upgrades require a permit in Texas. The work must be performed by a licensed electrician and pass inspection. Malco Electric handles all permit applications, inspections, and utility coordination as part of our service—you don't have to deal with the paperwork.
