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.

Andre Jones

Ant and Mark did an excellent job servicing my home today. They came out to give an estimate on my issue with no power to my water heater. They found that the water heater breaker was tripping and not resetting. I provided the breaker and they replaced that for me but they noticed in the laundry room was missing a bushing and the grounding wasn’t up to par along with a loose box. They did a great job of letting me know the issues and provided options for me. I will be recommending to family and friends the great work they completed for me. I now have hot water ; and now a happy customer!

Thank you Luciano for scheduling my mounting quote appointment promptly and efficiently. Kevin showed up and did an amazing job with the inspection he provided for our new home. Kevin was very knowledgeable and really seemed passionate about his work. I appreciate the great service!

Chris Schalk

Buck was extremely helpful. Replaced a GFCI and diagnosed a larger problem in our house. Explained everything really thoroughly and was really friendly. Enjoyed talking to him and having him in the house. Would absolutely come back to Misty Sparky again based on this experience.

Sam Small

Frank arrived, assessed the situation, and gave me options for what I want completed. He explained all options and once I made the decision, he went to work like a Boss! He was pleasant to talk with and answered all questions completely. What I liked most, he enjoyed doing what he knows how to do. He deserves a bonus! Thank you Frank and staff for getting here as quick as you did to complete an urgent matter. You’re tops in my book. Mr. Sparky will be my first and only call when service is required. OUTSTANDING!

New update 11/7/25- I had Mister Sparky out again for new electrical tasks since my first review. Again very pleased and will continue to call them for my needs. This time I had Matthew and team and it was a big job and they were extremely professional and respectful (and did a great job) Original review: Very pleased- Art was my electrician and he was so kind and professional. He did a great job hanging a very big light fixture on a very tall ceiling.
