Service Upgrades in San Antonio

Having electrical issues throughout your house? There could be several reasons you’re experiencing these issues. Components degrade and wear down, if you live in an older home, it could lack the necessary power to adequately run modern electronics. Homes without sufficient capacity will experience voltage drop-offs, which can permanently damage electrical equipment and appliances. If your home is more than 30 years old, it could be time for a service upgrade.

Panel Change

An electrical panel (also known as a “fuse box” or “breaker”) is a component of an electricity supply system. This component divides an electrical power feed into subsidiary circuits while providing a circuit breaker for each circuit in a common enclosure.

If your home needs panel changes in San Antonio, contact us today. We can upgrade your home’s electrical capabilities to feature the most advanced and powerful electrical panels available to industry professionals.

Circuit Box

Additionally, we can inspect your residential circuit box in San Antonio for any issues that might hinder electrical efficiency. From damaged circuits to improper installation, we’ll thoroughly examine your home’s circuit box in San Antonio and resolve any problems we find. Contact us today for more information.

Circuit Breakers

A circuit breaker is an automatically operated electrical switch that is designed to protect an electrical circuit from damages as a result of an overload or a short circuit. We have a wide variety of different circuit breakers that can be used for various voltage classes, current ratings, and breaker types. If you need to replace your old circuit breakers in San Antonio, contact us today.

FPE (Federal Pacific Electric) Electrical Panels

There are approximately 90,000 electrical fires per year in the United States and the majority are from faulty electrical panels. If you have a panel manufactured by FPE, you need to change it immediately. Panels made by FPE in San Antonio and across the United States are dangerous and pose fire risks.

FPE (or Federal Pacific Electric) was one of the most common manufacturers of circuit breaker panels from the 1950s to 1980s. However, throughout the years, FPE panels continually failed and caused numerous house fires.

If you have an FPE panel, contact Mister Sparky® of San Antonio immediately to get it removed and replaced with a safer, modern model.

Zinsco Panels

Another safety hazard to consider: panels made by Zinsco. In San Antonio and in other parts of the country, Zinsco parts are considered obsolete. This is because of a design flaw that causes the circuit breaker’s connection to the bar bus to loosen. This issue causes arcing and overheating problems.

Over time, parts and equipment made by Zinsco can cause the breaker to fuse to the bus bar. This fusing of metal makes it impossible to remove. This also prevents the circuits from tripping, which can pose a major fire hazard. Electrical service upgrades are not optional. If your home is outfitted with old, dangerous electrical equipment, count on us to provide the service that you need to ensure that your home’s electrical system is suitable for current requirements.

Everyone quit this company was amazing and we thank you very much from the bottom of our heart

Ron Heredia

Excellent service and installation of a severely worn out sub panel and checking our oven that caught fire recently. Timothy, Matthew and his helper (sorry forgot your name) were respectful and professional. Very clean work. Also added a surge protector to the main panel. Thank you, well worth the investment.

Darryn Christian

I recently had Mister Sparky San Antonio replace my outside breaker panel and the sub panel located in my garage, and I couldn’t be more impressed or pleased. Matt and Keith worked together seamlessly and exceeded all my expectations. They were not only highly knowledgeable and professional, but also incredibly friendly—I felt like I had known them for years by the end of the day. What stood out most was how they handled unexpected issues in real time, taking the time to explain everything clearly so I understood exactly what was happening. They even went above and beyond their original scope of work—replacing a ceiling fan with a burned-out motor and fixing an improperly installed outdoor light from a previous contractor. It was a truly great experience from start to finish. I wouldn’t hesitate to call on them again for future electrical needs. Highly recommended!

I needed a simple receptacle install to mount my LED mirror. Mr. Corey arrived to my house a lot earlier than expected. He was well mannered, knowledgeable, and easy going. Based on his work you could tell that it was professionally done and even cleaned up after himself. I will definitely be using this company so long as Corey works here. Thank you sir!

Julie Healy

I called Mister Sparky to install two pendant lights in my kitchen. Richard Cummings Jr. was my electrician and he did an amazing job. He was efficient, courteous, and extremely knowledgeable. Within minutes, I could tell that I had called the right company. I am very satisfied with my experience, and I would recommend Mr. Cummings and Mister Sparky to anyone. I will definitely be a repeat customer.
