What your neighbors are saying about us

Patrick was very professional! I cannot recommend him highly enough, and whatever company he is working for. I very much liked their maintenance plan. He explained it very well and we purchased it. I highly recommend this plan, this company and this technician.

We absolutely love Hunters for all our electrical needs. We had originally called them out bc someone redoing our floors had burned up an outlet. Christopher was very knowledgeable and polite. He explained all recommendations that he had in a way that I understood. They are the only company I will use for all our electrical needs and upgrades.

I am very pleased with the service I've received from Hunter Service Group. Stacy was kind, respectful of my home, and professional. The install was performed in a timely fashion and I couldn't be more pleased. I will use Hunter Services for any future needs that I have within your scope! Thank you!

I highly recommend Hunter Service Group. We have recently worked with Noe Garcia and Tony Ruiz to help my in-laws find the right home generator for them to add some peace of mind if the power goes out. Installation should take place in the next few weeks. It has been a great experience so far.

Signs Your Electrical Panel Needs to Be Upgraded or Replaced

Electrical panels don’t always fail dramatically. More often, they show gradual signs that something isn’t right. In San Antonio, where air conditioning runs hard for the better part of the year, an undersized or aging panel gets pushed to its limits on a regular basis. Watch for these warning signs:

Your breakers trip frequently, even under normal household loads.
Breakers trip but won’t reset, or reset only to trip again shortly after.
The panel feels warm, or you notice a burning smell near it.
Lights dim or flicker when large appliances like the AC or dryer kick on.
You’re adding new appliances, an EV charger, or a home addition, and your current panel can’t support the added load.
Your home still has a fuse box rather than a modern circuit breaker panel.
The panel is a known problematic brand, such as Federal Pacific or Zinsco.

Risks of an Outdated or Undersized Electrical Panel

An aging or undersized panel isn’t just an inconvenience. It’s a safety concern. When a panel can’t handle the electrical load being placed on it, it creates conditions that can lead to overheated wiring, arc faults, and in serious cases, electrical fires. Panels that use fuses instead of breakers, or that contain breakers that no longer trip correctly, lose their ability to protect your home the way they’re designed to.

Older panels also weren’t built for the electrical demands of today’s homes. The combination of high-efficiency HVAC systems, smart home devices, multiple large appliances, and EV chargers puts a level of sustained load on residential electrical systems that panels from 30 or 40 years ago simply weren’t designed to manage. In San Antonio, where AC systems run nearly year-round, that strain is compounded even further.

Enough capacity to support today’s appliances, HVAC systems, and future additions like EV chargers or solar.
Reduces the risk of tripped breakers and the frustration that comes with them.
Better performance from your electrical system overall, including more stable power delivery to sensitive electronics.

Frequently Asked Questions

How do I know if my electrical panel is a safety hazard?

If your panel is a Federal Pacific, Zinsco, or similar problematic brand, if breakers trip frequently or fail to trip when they should, or if you notice warmth or a burning smell near the panel, these are all reasons to have a licensed electrician evaluate it as soon as possible.

How long does an electrical panel upgrade take?

Most panel replacements are completed in a single day. The work requires a temporary power shutoff while the new panel is installed. We’ll coordinate everything, including any required utility disconnects, and let you know what to expect before we start.

How much amperage does my home need?

Most older homes were built with 100-amp service, which is often no longer sufficient for modern electrical demands. Many homes today benefit from upgrading to 200-amp service, and homes with EV chargers, large HVAC systems, or significant square footage may need even more. Our electricians will assess your load and recommend the right capacity.

Is a permit required for panel replacement in San Antonio?

Yes. Panel replacement and upgrades require a permit and inspection in San Antonio. Hunter Service Group handles the permitting process as part of our service, so you don’t have to manage it yourself.

Will upgrading my panel increase my home's value?

It can. A modern, properly sized electrical panel is viewed favorably during home inspections and appraisals. For older homes with outdated panels, an upgrade can remove a common obstacle that comes up during real estate transactions.
